ICE Series  
General Information  
How To Use This Manual  
Ice-O-Matic provides this manual as an aid to the service technician in installation, operation,  
and maintenance of the ICE Series (electro-mechanical) cube ice machines. If used properly  
this manual can also assist the service technician to troubleshoot and diagnose most of the  
problems that may occur with the machine.  
The first two sections of this manual provide general information and maintenance information.  
The remainder of the manual beginning with Section C provides troubleshooting and service  
information. Section C contains flow charts called troubleshooting trees. Page C-1 provides  
instructions on using the troubleshooting trees. Each troubleshooting tree is named to describe  
a particular problem with the operation of the machine.  
When following the troubleshooting trees, the service technician will be led through questions  
and checks and end up with a probable solution. When using the troubleshooting trees, it is  
important that the service technician understand the operation and adjustments of the  
components being checked and the component suspected of malfunctioning. A detailed  
description of the operation and adjustments of the components as well as other service  
information is available in the pages that follow Section C.  
Sections D, E, and F focus on a particular system in the ice machine: water distribution system,  
refrigeration system, and it is important that these sections be used together with the  
Troubleshooting Trees in Section C.  
Most aspects of the ICE Series machines are covered in this manual, however, should you  
encounter any conditions not addressed herein, please contact the Ice-O-Matic Technical  
Service Department for assistance. You may also fax, e-mail or write the Ice-O-Matic Technical

ICE Series  
General Information  
Model and Serial Number Format  
Since all Enodis companies will eventually be  
utilizing same operating system, a company wide  
format for serial numbers has been designed.  
This format is 14 characters long and begins with a  
date code followed by the Ice-O-Matic identifier, and  
then a sequential number. This is an entirely  
numerical serial number.  
The new serial number will look like the example.  
0407 1280 010123  
010123 is the serial identifier.  
1280 is the identifier. (Ice-O-Matic)  
0407 is the date code, in YYMM format. (2004 July)  
The date code will change monthly and yearly to  
reflect the date of manufacture.  
Large data plate will be placed on the back of  
the unit.  
Small data plate will be placed by the service  
valves.

Remote Condenser Installation  
For proper operation of the Ice-O-matic ice machine, the following installation guidelines must be  
followed. Failure to do so may result in loss of production capacity, premature part failure, and  
may void all warranties.  
Installation Guidelines  
 Ambient operating temperatures: -20°F (-28.9°C) to 120°F (48.9°C)  
 Maximum refrigerant line length: 60 ft. (18.29 Meters)  
 Maximum vertical rise:  
16 ft. (4.88 Meters)  
 Minimum condenser height:  
ICE Series ice machine remote condensers must not be  
installed more than 6 feet (1.3 meters) below the refrigerant line quick connects at the rear of the  
ice machine. No part of the refrigerant lines, between the ice machine and the remote  
condenser, should fall below this point. Condensers must have a vertical airflow.

General Information  
The following remote ice makers incorporate the mixing valve in the condenser. This configuration allows  
up to a 100 foot calculated remote line set run. Reference the diagram below to calculate the maximum 100  
foot line set run.

Limitations for new remote machines that have the mixing valve mounted in the condenser.  
Maximum Rise is 35 feet.  
Maximum Drop is 15 feet.  
Maximum equivalent run is 100 feet.  
Formula for figuring maximum equivalent run is as follows:  
Rise x 1.7 + Drop x 6.6 + horizontal run = equivalent run.  
Examples: 35 ft. rise x 1.7 + 40 ft. horizontal = 99.5 equivalent feet line run  
35 ft. rise  
40 ft. horizontal  
Verify the ICE machine is compatible with the remote  
condenser. Some ice machines and some remote  
condensers may or may not have a Mixing Valve (Head  
Master). Only one valve is required per system. Kits are  
available to modify the condenser for compatibility. For  
more information contact your Ice-O-Matic Distributor.

ICE Series  
General Information  
How the ICE Machine Works  
A general description of how the ICE Series cubers work is given below. The remainder of the  
manual provides more detail about the components and systems.  
With the ICE/OFF/WASH switch in the ICE position, the compressor, water pump and condenser  
fan motor (when applicable) will energize starting the freeze cycle.  
During the freeze cycle, water is circulated over the evaporator(s) where the ice cubes are formed.  
When the suction pressure has pulled down to the proper cut-in pressure of the timer initiate  
(pressure control), the contacts will close and energize the time delay module (timer). See Page  
F3 for proper cut-in pressures. At this time the cubes will close to completion.  
The remaining portion of the freeze cycle is determined by the timer setting. The timer is pre-set at  
the factory to achieve the proper ice bridge thickness but may need to be adjusted upon initial  
start-up, see Page F4 for initial timer settings.  
Once the amount of time on the timer has passed, the control relay will be energized and the  
machine will enter harvest. Power is now supplied to the water purge valve, hot gas valve, and the  
harvest motor. The water purge valve opens, and allows the water pump to purge the water  
remaining in the water, removing impurities and sediment. This allows the machine to produce  
clear ice cubes and keep mineral build up at a minimum. The hot gas solenoid opens allowing hot  
gas to go directly to the evaporator, heating the evaporator and breaking the bond between the  
evaporator and the ice slab.  
The harvest assist motor, which is also energized during harvest, turns a slip clutch, which pushes  
a probe against the back of the ice slab. Once the evaporator has reached approximately 40°F  
(4.5°F) in temperature, the slip clutch overcomes the bonding of the ice to the evaporator and  
pushes the slab of ice off of the evaporator and into the storage bin. The clutch also actuates a  
switch that rides on the outer edge of the clutch. When the clutch completes one revolution, the  
switch is tripped and the machine enters the next freeze cycle.  
When ice drops into a full bin during harvest, the splash curtain is held open which activates a bin  
switch shutting the machine off. When ice is removed from the bin, the splash curtain will close  
and the machine will come back on.

ICE Series  
Scheduled Maintenance  
Cleaning and Sanitizing (continued)  
5. Add recommended amount of approved Nickel Safe ice machine cleaner to the water trough  
according to label instructions on the container.  
6. Initiate the wash cycle at the ICE/OFF/WASH switch by placing the switch in the “WASH”  
position. Allow the cleaner to circulate for approximately 15 minutes to remove mineral  
deposits.  
7. Depress the purge switch and hold until the ice machine cleaner has been flushed down the  
drain and diluted by fresh incoming water.  
8. Terminate the wash cycle at the ICE/OFF/WASH switch by placing the switch in the “OFF”  
position. Remove the splash curtain and inspect the evaporator and water spillway to assure all  
mineral residue has been removed.  
9. If necessary, wipe the evaporator, spillway and other water transport surfaces with a clean soft

10. Turn OFF ice machine water supply and clean the water trough thoroughly to remove all scale  
or slime build-up. If necessary, remove the water trough to reach all splash areas and float.  
11. Prepare 1½ to 2 gallons (5.7 to 7.5 liters) of approved (EPA/FDA) sodium hypochloride food  
equipment sanitizer to form a solution with 100 to 200 ppm free chlorine yield.  
12. Add enough sanitizing solution to fill the water trough to overflowing and place the  
ICE/OFF/WASH switch to the “WASH” position and allow circulation to occur for 10 minutes  
and inspect all disassembled fittings for leaks. During this time, wipe down all other ice  
machine splash areas, plus the interior surfaces of the bin, deflector and door with the  
remaining sanitizing solution. Inspect to insure that all functional parts, fasteners, thermostat  
bulbs (if used), etc. are in place.  
13. Depress the purge switch and hold until sanitizer has been flushed down the drain. Turn ON  
the ice machine water supply and continue to purge to the diluted sanitizing solution for another  
1 to 2 minutes.  
14. Place the ICE/OFF/WASH switch to the “ICE” position and replace the front panel.

Cabinet Care  
Cleaning stainless steel  
Commercial grades of stainless steel are susceptible to rusting. It is important that you properly  
care for the stainless steel surfaces of your ice machine and bin to avoid the possibility of rust or  
corrosion. Use the following recommended guidelines for keeping your stainless steel looking like  
new:  
1. Clean the stainless steel thoroughly once a week. Clean frequently to avoid build-up of  
hard, stubborn stains. Also, hard water stains left to sit can weaken the steel's corrosion  
resistance and lead to rust. Use a nonabrasive cloth or sponge, working with, not across, the  
grain.  
2. Don't use abrasive tools to clean the steel surface. Do not use steel wool, abrasive sponge  
pads, wire brushes or scrapers to clean the steel. Such tools can break through the "passivation"  
layer - the thin layer on the surface of stainless steel that protects it from corrosion.  
3. Don't use cleaners that use chlorine or chlorides. Don't use chlorine bleach or products like  
Comet to clean the steel. Chlorides break down the passivation layer and can cause rusting.  
4. Rinse with clean water. If chlorinated cleansers are used, you must thoroughly rinse the  
surface with clean water and wipe dry immediately.  
5. Use the right cleaning agent. The table below lists the recommended cleaning agents for  
common stainless steel cleaning problems:  
Cleaning Activity  
Cleaning Agent  
Method of Application  
Routine cleaning  
Soap, Ammonia, Windex, or  
detergent with water.  
Fantastik, 409 Spic’nSpan  
Liquid are also approve for  
Stainless Steel.  
Apply with a clean cloth  
or sponge. Rinse with  
clean water and wipe dry.  
Removing grease or  
fatty acids  
Easy-Off or similar oven  
cleaners.  
Apply generously, allow  
to stand for 15-20 minutes.  
Rinse with clean water.  
Repeat as required.  
Removing hard water spots  
and scale.  
Vinegar  
Swab or wipe with clean cloth.  
Rinse with clean water and  
dry.

Troubleshooting Trees  
How To Use The Troubleshooting Trees  
The troubleshooting trees were developed to be used in conjunction with the service information in  
the sections that follow. If used together as intended, these two parts of the manual will allow the  
ice machine service technician to quickly diagnose many of the problems encountered with the ice  
machines. When used as designed, the troubleshooting trees can lead you from a general  
symptom to the most likely component to suspect as the cause of the problem. The trees are not  
designed to be “parts changer guides”: please do not use them as such.  
Components returned to the factory for warranty are tested by the factory and will not be covered  
under the warranty policy if they are not defective.  
The troubleshooting trees are made of three types of boxes:  
?
9
!
QUESTION boxes (Circle) ask a yes/no question and the answer will lead to either another  
question box, a check box or a solution box.  
CHECK boxes (Rectangle) will suggest a point to check for proper operation, and will often refer  
you to a page in the service information sections of this manual. The result of the check may lead  
to another box, or a solution box.  
SOLUTION boxes (Hexagon) suggest the most likely component to cause the malfunction  
described in the heading of the tree. When reaching a solution box, DO NOT immediately assume  
the component is defective. The final step is to verify that the component is indeed defective, by  
using the service information in the sections that follow.  
To use the troubleshooting trees, first find the page with the heading describing the type of  
problem occurring. Begin at the top of the page and follow the tree, step-by-step. When a check  
box is reached, it may be necessary to refer to another section in the manual.  
Once a solution box is reached, refer to the appropriate section to verify that the component in the  
solution box is, indeed, the problem. Adjust, repair or replace the component as necessary.

Water System  
Water Distribution and Components  
Water enters the machine through the float valve located in the water trough. The water trough  
holds water used for ice making. The float valve is used to maintain the proper water level in the  
water trough. During the freeze cycle water is continuously circulated over the evaporator by the  
water pump. When the machine enters harvest, the purge valve (not shown) opens and mineral  
laden water is pumped out of the water trough to the drain. After water is purged from the trough,  
the water pump and purge valve are de-energized and the trough refills.  
Float Valve  
The water level can be adjusted by carefully bending the arm of the float. The water level should  
be ½ inch (13mm) above the top of the water pump impeller housing during the freeze cycle.  
If the float valve does not allow water into the trough or water flow is slow, the float valve may be  
restricted. Remove and disassemble the float valve and clean the orifice. If the water flow is still  
slow, check the water pressure to be sure it is at least 20 PSI (1.4 bar).  
If the float valve does not stop the water flow, make sure the water pressure to the machine does  
not exceed 60 PSI (4.1 Bar). Install a water pressure regulator if the pressure is too high. If the  
water pressure is not the problem, the float plunger or the entire float valve assembly may need to  
be cleaned or replaced.

ICE Series  
Water System  
Water Distribution Tube  
Water is pumped to a distribution tube located at the top of the evaporator and is used to distribute  
water evenly over the evaporator. The distribution tube can be removed and dissembled for  
cleaning if the hole becomes plugged or if there is excessive mineral build-up in the water system.  
The water distribution tube is a tube within a tube. Water enters and fills the inner tube and exits  
through a series of holes along the top of the inner tube. Water then fills the outer tube and exits  
through a series of holes along the bottom of the outer tube. For proper water flow over the  
evaporator, it is important that the tube be assembled correctly after cleaning. The tube can be  
checked for proper assembly by checking the “bump” on the flanges at the tube ends, the “bump”  
should be at the top.  
Water Distribution Disassembly  
Remove 2 screws holding the distribution tube to the evaporator spillway. Remove the clamp  
holding the water tube to the distribution tube. Twist the end caps of the distribution tube  
counterclockwise and pull to remove the inner tube halves from the outer tube. To reassemble,  
push the inner tube halves into the outer tube with the holes facing the same direction. Make sure  
the inner tube halves seat together completely. Twist the end caps clockwise ½ turn to lock the  
inner tubes in place. The holes in the tubes will now be facing in the opposite directions.  
Important! For proper water flow over the evaporator, the inner tube holes must face up.  
Turn counterclockwise to remove

Water System  
Water Splash Curtain  
The water splash curtain covers the evaporator to prevent water from splashing into the bin and is  
also used to actuate the bin switch. When the bin becomes full of ice, the splash curtain is held  
open when the ice drops off of the evaporator. The actuator tab or wire bale on the splash curtain  
will release pressure on the bin switch and the machine shuts off. See bin control on page F9.  
On single evaporator units, the splash curtain can be opened or removed during the freeze cycle  
and the machine will continue to run until the ice drops from the evaporator. On dual evaporator  
units, if the curtain is opened or removed during the untimed freeze cycle, or during defrost, the  
machine will shut down. If the curtain is opened or removed during the timed freeze cycle, the unit  
will continue to operate.  
The splash curtain can be removed by swinging the bottom of the curtain away from the  
evaporator and lifting the right side of the curtain up and out of the hinge pin slot. To reinstall the  
curtain, position the left side pin into the slot first, then insert the right hand side with the actuator  
tab of the curtain behind the bin switch.  
Note: The ICE0250 and ICE0305 utilize a curtain-retaining clip. The ICE Undercounter Series  
ice machines do not utilize a splash curtain.

Water System  
Water Purge Valve  
When the machine enters the harvest cycle, the water pump continues to run and the purge valve  
opens. This allows mineral laden water to be pumped from the water trough to the drain. This  
helps keep the water system clean. The water pump and purge valve de-energizes once the water  
is flushed from the water trough. The cam switch controls the length of time that the water pump  
and purge valve remains energized see page F7. The purge valve can also be energized  
manually by pushing the purge switch. The purge switch is used when cleaning the water system  
to flush cleaning solution down the drain. See page B1 for cleaning instructions.  
The purge valve must be completely closed during the freeze cycle. If water leaks through the  
purge valve during the freeze cycle, the freeze cycle will be extended due to the float allowing  
warm water into the trough and poor ice formation will result. The purge valve may be defective or  
need cleaning.  
The purge valve can be disassembled for cleaning by:  
1. Disconnect electrical power form the ice machine.  
2. Lift and remove the coil retainer cap.  
3. Leave the coil wires attached to the coil and lift coil from the valve body. (Note coil orientation)  
4. Rotate the enclosing tube ¼ turn counterclockwise to remove.  
5. Remove the enclosing tube, plunger and diaphragm from the valve body  
6. Reverse procedure to reassemble.  
The purge valve can be easily cleaned or rebuilt without  
removing the entire valve body. Dirty or clogged purge  
valves are not considered a warranty repair.

Refrigeration System  
Refrigerant Cycle and  
Components  
Before diagnosing the refrigeration  
system, it is very important that the  
refrigerant charge be correct.  
Whenever the refrigeration system  
has been opened, the filter-drier  
must be replaced and the proper  
refrigerant charge must be weighed  
in. See refrigerant charge data on  
page A5–A8.  
Refrigerant Pressures  
The suction pressure at the  
beginning of the freeze cycle can vary +/- 10 psi  
(.7 bar) depending on operating conditions. Reference Chart on page E10-E13. Pressures less  
than this may indicate an undercharge. The discharge pressure on water-cooled units should be  
250 psi (17.01 bar) for R404a units and 150 psi (10.21 bar) for R134a units. The discharge  
pressure on air cooled units will vary with ambient conditions but will typically run higher than water  
cooled units. Remote condensers located in ambient temperatures below 70°F (21°C) will typically  
run a lower discharge pressure. See Mixing Valve later in this section.  
Refrigerant in a gas state is pumped throughout the refrigeration system by a hermetic  
compressor to the condenser. Heat is removed from the refrigerant either by forced air  
movement through an air-cooled condenser or transferring heat from the refrigerant to water  
through a water-cooled condenser. The refrigerant changes to a liquid when cooled.  
The refrigerant in a liquid state passes through a filter drier. The filter drier traps  
small amounts of moisture and foreign particles from the system. The filter drier must  
be replaced whenever the refrigeration system is opened or if the refrigerant charge  
has been completely lost.  
Compressor  
The compressor runs during the entire cycle. If the valves in the  
compressor are damaged, the compressor will be unable to pump  
refrigerant efficiently. Damaged valves are usually the result of another  
problem in the refrigeration system such as liquid refrigerant returning to  
the compressor, oil slugging or high head pressure. When a compressor  
is replaced it is important that the refrigerant charge be weighed in and  
the system checked for proper operation to prevent a repeat failure.  
An inefficient compressor will usually have a higher than normal suction  
pressure at the end of the cycle. The freeze cycle will be longer than normal and/or the harvest  
cycle may be excessively long. Check the compressor amperage draw 5 minutes into the freeze  
cycle. If the compressor amp draw (Reference data plate on ice machine back panel) is less than  
70% of rated full load amps, the compressor may be inefficient. These symptoms may also be  
caused by other problems, therefore it is important to use the troubleshooting trees when  
diagnosing a problem. See Electrical System for more information on the compressor and  
compressor start components.

ICE Series  
Refrigeration System  
Refrigerant  
Refrigerant in a high-pressure liquid form is fed to an expansion valve where the refrigerant is  
reduced to a low-pressure liquid. Under this low pressure, the liquid will absorb heat from the  
evaporator causing the liquid to change to a vapor. This vapor is then drawn into the compressor  
where the temperature and pressure of the vapor are increased. The high temperature, high  
pressure vapor flows to the condenser where the heat is removed, causing the vapor to return to  
the liquid form, making the refrigerant ready to flow back to the evaporator to pick up more heat.  
Most Ice-O-Matic ice machine use R134a or R404a refrigerant. Always check the serial number  
data plate for the proper type of refrigerant and the amount used in the machine you are servicing.  
R404a and R134a are both HFC refrigerants, which result in no ozone depletion factor. R404a  
cylinders are orange in color, R134a cylinders are light blue in color.  
Important: When discharging refrigerant from an icemaker, recover as much of the  
refrigerant as possible with a recovery device or some other means to prevent the  
refrigerant from entering the atmosphere.  
Method of Charging Refrigerant  
In order to achieve a properly charged refrigeration system, the system must be completely  
evacuated.  
To achieve a complete evacuation you will need a service gauge manifold with properly maintained  
hoses, and a vacuum pump capable of pulling a 50-micron vacuum. This will require a two-stage  
pump.  
Connect the service gauge manifold to the high and low side service ports and vacuum pump.  
Make sure the valves on the gauge manifold are closed, then start the pump.  
Note: Do not use a refrigeration compressor as a vacuum pump. Compressors are able to  
pull only a 50,000-micron vacuum.  
After the vacuum pump has been started, open the valves on the gauge manifold. This will allow  
the refrigeration system to start being evacuated.  
If there has not been an excessive amount of moisture in the system, allow the vacuum pump to  
pull the system down to about 200 microns or 29.9 inches or less. Once this has been achieved,  
allow the vacuum pump to operate for another 30 minutes. Then close the valves on the gauge  
manifold and stop the vacuum pump. Then watch your gauges. A rise to 500 microns in three (3)  
minutes or less indicates a dry system under a good vacuum.  
If your gauge registers a more rapid rise, the system either has moisture remaining or there is a  
leak in the system, requiring a check for the leak, and repair and another complete evacuation.  
Note: Seal the ends of the gauge manifold hose and pull them into a deep vacuum to determine if  
the leak is not in the hoses. The gauge manifold should be able to hold the vacuum for three (3)  
minutes.

ICE Series  
Refrigeration System  
Thermostatic Expansion Valve (TXV)  
The thermostatic expansion valve meters the flow of refrigerant into the  
evaporator changing its state from a high-pressure liquid to a low-pressure  
liquid. This drop in pressure causes the refrigerant to cool. The cooled  
refrigerant absorbs heat from the water circulating over the evaporator. As  
the evaporator fills with liquid refrigerant, the evaporator becomes colder.  
The flow of refrigerant into the evaporator is controlled by the temperature at the outlet of the  
evaporator. The expansion valve bulb, mounted to the top of the suction line, senses the  
evaporator outlet temperature causing the expansion valve to open or close. As ice forms on the  
evaporator, the temperature drops and the flow of refrigerant into the evaporator decreases,  
resulting in a drop in suction pressure.  
The evaporator should become completely flooded (filled with liquid refrigerant) during the freeze  
cycle. A completely flooded evaporator will have a uniform freeze pattern (ice formation across the  
evaporator). A starved evaporator (not enough liquid refrigerant) will have poor or no ice formation  
at the top of the evaporator, and the tube(s) exiting the evaporator will not frost. All tubes should  
be within 10 degrees of each other and frosted approximately 5 minutes from the start of the freeze  
cycle.  
An expansion valve that is restricted or not opening properly will starve the evaporator resulting in  
lower than normal suction pressure. A low refrigerant charge will also starve the evaporator and  
cause low suction and discharge pressures. If not sure of the amount of charge in the system, the  
refrigerant should be recovered and the correct charge be weighed in before a defective valve can  
be diagnosed.  
If the evaporator is starved but the suction pressure is higher than normal, the TXV is not the  
problem; refer to the troubleshooting tree in section C. If the TXV sticks open or if the thermal bulb  
is not making good contact with the suction line, the flow of refrigerant into the evaporator will be  
too great and liquid refrigerant will flood the compressor. The suction pressure will remain higher  
than normal and the machine will remain in an extended freeze cycle. Ice will build evenly but will  
be very thick.

ICE Series  
Refrigeration System  
Thermostatic Expansion Valve (Continued)  
A dual evaporator machine will have one TXV for each evaporator. If one TXV sticks open and the  
other is operating normally, the suction pressure will be higher than normal and both evaporators  
will build thick ice. It is recommended that both valves be replace if one sticks open.  
If one TXV sticks closed and one is operating normally, the suction pressure will be normal or low  
but the evaporator with the defective valve will be starved (thick ice at the bottom and thin ice at  
the top).  
Evaporator  
As water is circulated over the front of the evaporator, liquid refrigerant is circulated through the  
tubing attached to the back of the evaporator. As the liquid refrigerant in the tubing vaporizes, it  
absorbs heat from the water causing the water to freeze. The evaporator should be completely  
flooded throughout most of the freeze cycle. A flooded evaporator will build ice evenly across the  
evaporator. A starved evaporator will have uneven ice formation. Most problems with ice  
formation or harvesting are not related to a defective evaporator, use the Troubleshooting Trees in  
section C for additional help.  
Refrigerant enters the evaporator through the bottom tube and exits through the top tube. On  
models ICE800, 1000, 1800 and 2100 the refrigerant line at the TXV outlet splits into two feeder  
tubes. This split occurs at the distributor, which is a fitting that is soldered to the TXV. One feeder  
tube from the distributor feeds the top of the evaporator; the other tube feeds the bottom of the  
evaporator. The evaporator tubes run parallel, in opposite directions, along the back of the  
evaporator creating a dual pass.  
If the evaporator is flooded but not building ice evenly, it is possible the evaporator has coil  
separation. Evaporator coil separation is the separation of the refrigerant tubing from the back of  
the evaporator plate. This is very rare but occasionally occurs.  
To confirm coil separation, remove and check the back of the evaporator. If the coil is separated,  
the evaporator must be replaced. If the outlet(s) of the evaporator is not frosted, the problem is not  
with coil separation (Refer to the troubleshooting trees, section C).

Refrigeration System  
Note: Permanent discoloration of the evaporator plating is normal and will cause no problems with  
harvesting the ice or sanitary conditions. Before condemning the evaporator for plating problems,  
be certain it is not just discoloration. Good evaporators will not be covered under warranty. If the  
spillway (plastic evaporator top) becomes damaged, it can be replaced. It is not necessary to  
replace the entire evaporator.  
As liquid refrigerant leaves the evaporator, it changes to a low-pressure gas before returning to the  
compressor. Liquid refrigerant must not return to the compressor or damage will result. Frost on  
the suction line at the inlet of the compressor indicates liquid returning to the compressor. Check  
for frost at the end of the freeze cycle. If liquid is returning to the compressor, the problem must be  
located and corrected. See Refrigerant Charge, Thermostatic Valve and Evaporator.  
Harvest Cycle  
Once the freeze cycle is complete, the machine enters the harvest cycle. The hot gas valve  
opens to allow hot discharge gas to enter the evaporator.  
Hot Gas Valve  
When the machine enters harvest the hot gas valve coil is energized opening  
the hot gas valve. Discharge gas is pumped through the hot gas valve directly  
into the evaporator. The evaporator temperature will reach approximately 40°F  
(4.5°C). The suction pressure during harvest should be a minimum of 70 psi  
(4.8 bar) for R404a units or 50psi (3.4 bar) for R134a units. The discharge  
pressure will drop during harvest.  
If the hot gas valve does not completely open during harvest, there will not be enough hot gas in  
the evaporator to defrost the ice. If there is not enough hot gas entering the evaporator, the  
suction pressure will be lower than the above stated pressures. It is important when making this  
check that the machine has the proper refrigerant charge, normal head pressure and the  
compressor is functioning properly. If the hot gas valve leaks during the freeze cycle, ice will not  
form on the top of the evaporator and suction pressure will be higher than normal. To check if the  
hot gas valve is leaking, let the machine run in the freeze cycle for approximately 5 minutes. Now  
feel the temperature between the inlet and outlet of the valve. A definite temperature difference  
should be felt. If the lines are the same temperature and the suction pressure is higher than  
normal; the valve is leaking and should be replaced. Use Troubleshooting Trees in section C.  
Remote System  
Machines that use remote condensers have several components that are not used in self  
contained machines. A mixing valve controls the head pressure when the ambient temperature at  
the condenser drops below 70°F (21°C). When the bin fills with ice or is turned off at the selector  
switch, the machine will pump all the refrigerant into the receiver before shutting off.  
Remote Condenser  
For proper operation, the remote condenser must be installed properly.  
Improper installation will void the warranty. See remote guidelines on page  
A18. The location of the remote condenser should be such that the ambient  
air temperature does not exceed 120°F (48.9°C). If ambient temperature  
exceeds 120°F (48.9°C) ice production will decrease until the ambient  
temperature decreases.

ICE Series  
Refrigeration System  
Remote Condenser (Continued)  
If the airflow is restricted or the condenser is dirty, the head pressure will be excessively high, slow  
production will result and the compressor may overheat and eventually become damaged. The  
condenser coil and fan blades must be kept clean. The condenser can be cleaned with  
compressed air or by using a brush. If a brush is used, brush in the direction of the fins taking care  
not to bend the fins. If the condenser fins are bent, this will restrict the airflow through the  
condenser and the fins will need to be straightened with a fin comb. Problems related to a dirty  
condenser or poor airflow will not be covered under warranty. Note: The condenser fan motor runs  
continually, it will shut off when the icemaker shuts off.  
Mixing Valve  
When the temperature at the condenser is above 70°F (21°C), the refrigerant flow from the  
compressor is directed by the mixing valve through the condenser and into the receiver. When the  
temperature at the condenser drops below 70°F (21°C), the pressure in the bellows of the mixing  
valve becomes greater than the pressure of the liquid refrigerant coming from the condenser. This  
change allows the valve to partially restrict the flow of  
refrigerant leaving the condenser and allows discharge  
gas to by-pass the condenser and flow directly into the  
receiver, mixing with the liquid refrigerant from the  
condenser. The amount of discharge gas that  
bypasses the condenser increases as the ambient  
temperature decreases. This action of the mixing  
valve allows the discharge pressure to be maintained  
at approximately 240 psi (16.5 bar) during low ambient  
conditions. If the refrigerant system is undercharged  
and the ambient temperature is below 70°F (21°C), the  
mixing valve will not work properly. The mixing valve  
will allow too much refrigerant to bypass the  
condenser.

Refrigeration System  
Pump Down System (Remote Only)  
The pump down system prevents liquid refrigerant from migrating to the evaporator and  
compressor during the off cycle and prevents the compressor from slugging or starting under an  
excessive load.  
Liquid Line Solenoid  
When a machine with a remote condenser shuts off, the liquid line solenoid valve,  
located at the outlet of the receiver, is de-energized causing the valve to close  
completely restricting the flow of refrigerant. The compressor will pump all of the  
refrigerant into the condenser and receiver.  
As the system pumps down, the pressure on the low side of the system drops. When the suction  
pressure drops to 10 psi (.68 bar), the pump down control opens and shuts the machine off. See  
page F9 for pump down control operation. Liquid refrigerant is stored in the condenser and  
receiver while the machine is off. It is normal for the machine to pump down once or twice an hour  
as the pressures equalize.  
When the machine comes back on (the bin switch closes or the selector switch placed to the ICE  
position), the liquid line solenoid valve opens and the refrigerant is released from the receiver.  
When the suction pressure rises to 35 psi (2.38 bar) the pump down control closes and the  
machine comes back on. If the machine will not pump down, the valve may not be closing all the  
way. A weak compressor will also prevent the machine from pumping down. Check for signs of a  
weak compressor before replacing the liquid line solenoid. Prior to replacing the valve,  
disassemble and check for obstructions that may not allow the valve to seat.  
Receiver  
If the system has a remote condenser, the refrigerant will enter a receiver before  
passing through the filter drier. The receiver holds reserve liquid refrigerant during  
the freeze cycle. The receiver also stores liquid refrigerant during the off cycle.

Refrigeration System  
Refrigerant  
Refrigerant in a high-pressure liquid form is fed to an expansion valve where the refrigerant is  
reduced to a low-pressure liquid. Under this low pressure, the liquid will absorb heat from the  
evaporator causing the liquid to change to a vapor. This vapor is the drawn into the compressor  
where the temperature and pressure of the vapor are increased. The high temperature, high  
pressure vapor flows to the condenser where the heat is removed, causing the vapor to return to  
the liquid form, making the refrigerant ready to flow back to the evaporator to pick up more heat.  
Most Ice-O-Matic ice machine use R134a or R404a refrigerant. Always check the serial number  
data plate for the proper type of refrigerant and the amount used in the machine you are servicing.  
R404a and R134a are both HFC refrigerants, which result in no ozone depletion factor. R404a  
cylinders are orange in color, R134a cylinders are light blue in color.  
Important: When discharging refrigerant from an icemaker, recover as much of the  
refrigerant as possible with a recovery device or some other means to prevent the  
refrigerant from entering the atmosphere.  
Method of Charging Refrigerant  
In order to achieve a properly charged refrigeration system, the system must be completely  
evacuated.  
To achieve a complete evacuation you will need a service gauge manifold with properly maintained  
hoses, and a vacuum pump capable of pulling a 50-micron vacuum. This will require a two-stage  
pump.  
Connect the service gauge manifold to the high and low side service ports and vacuum pump.  
Make sure the valves on the gauge manifold are closed, then start the pump.  
Note: Do not use a refrigeration compressor as a vacuum pump. Compressors are able to  
pull only a 50,000-micron vacuum.  
After the vacuum pump has been started, open the valves on the gauge manifold. This will allow  
the refrigeration system to start being evacuated.  
If there has not been an excessive amount of moisture in the system, allow the vacuum pump to  
pull the system down to about 200 microns or 29.9 inches or less. Once this has been achieved,  
allow the vacuum pump to operate for another 30 minutes. Then close the valves on the gauge  
manifold and stop the vacuum pump. Then watch your gauges. A rise to 500 microns in three (3)  
minutes or less indicates a dry system under a good vacuum.  
If your gauge registers a more rapid rise, the system either has moisture remaining or there is a  
leak in the system, requiring a check for the leak, and repair and another complete evacuation.  
Note: Seal the ends of the gauge manifold hose and pull them into a deep vacuum to determine if  
the leak is not in the hoses. The gauge manifold should be able to hold the vacuum for three (3)  
minutes.

ICE Series  
Refrigeration System  
If the refrigeration system is extremely wet, use radiant heat to raise the temperature of the  
system. This action will cause the moisture to vaporize at less of a vacuum.  
The use of two (2) valves, one between the vacuum pump and gauge manifold and the other  
between the refrigerant cylinder and the gauge manifold allows you to evacuate and charge the  
system without disconnecting any hoses. If the hoses were disconnected, air or moisture will have  
the opportunity to enter the hoses and then the system.  
A properly charged icemaker is a service technician’s greatest ally. Proper charging will allow any  
concern with the icemaker to be accurately diagnosed.  
The refrigerant charge must be weighed into the icemaker either by using a charging scale or with  
a dial-a-charge.  
The amount of proper refrigerant required for the icemaker is printed on the serial data plate  
attached to the icemaker and is listed on the following pages. Never vary the amounts from those  
listed.  
Remote models with sixty (60) foot lineset runs will need an additional fifteen (15) ounces of  
refrigerant added.  
In some cases the complete refrigerant charge may not enter the refrigeration system. In those  
instances, close the gauge manifold high side valve and disconnect the manifold from the high side  
port.  
When the icemaker is completely charged, secure the caps to the service ports and check to make  
sure the ports are not leaking refrigerant.

ICE Series  
Electrical System  
Control Circuit  
All machines in this manual are electro-mechanical controlled; however the control circuitry on the  
single evaporator units differs from the dual evaporator units and is detailed below.  
Selector Switch  
The selector switch is used to put the machine into the ICE making or WASH cycle or to turn the  
machine OFF. The WASH position allows only the water pump to run and is used during the  
cleaning process to circulate cleaning solution throughout the water system. When the selector  
switch is turned to the ICE position, the machine begins the freeze cycle.  
Contactor  
When the selector switch is in the ICE position, the contactor coil is energized and  
pulls in the contactor contacts. This energizes the compressor start components,  
which starts the compressor.  
Purge Switch  
The purge switch is a momentary switch used to manually energize the purge valve. It is used  
during the cleaning process to flush the cleaning solution from the water trough. The purge valve  
will remain energized as long as the purge switch is depressed.  
Note: Single Evaporator Units. The normally closed contacts of the purge switch also create a  
circuit to relay 1. These contacts should remain closed unless the switch is depressed. If the  
switch is defective and the normally closed contacts are open when the machine enters harvest,  
the machine will return to freeze when the timer initiate control opens.  
Compressor and Start Components  
The compressor should run during the entire cycle. If the machine is in the ICE position but the  
compressor is not running, check the compressor contactor to see if it is engaged. If the contactor  
is not engaged, the problem is not with the compressor or the compressor start components. If the  
contactor is engaged and there is correct voltage through the contactor, there could be a problem  
with one of the starting components or the compressor. It is recommended that the compressor  
starting components be replaced when replacing a compressor.  
Compressor Check  
Disconnect power before servicing  
If the compressor uses an  
internal overload, be  
certain that the compressor has cooled and the overload has reset before diagnosing the  
compressor. If the compressor is cool and is still not running, check the compressor motor  
windings by first removing the wires at the compressor terminals. With an ohmmeter, check for  
continuity between all three terminals, if an open circuit exists between any of the terminals, the  
compressor may need to be replaced. Check for continuity from each terminal to the compressor  
body, if continuity is found from any terminal to the compressor body, the compressor windings are  
shorted to ground and the compressor will need to be replaced. If the compressor appears to be  
good at this point, it is advisable to use a compressor analyzer to isolate the compressor from the  
start components while checking for a locked rotor. If an analyzer is not available, the compressor  
starting components must be checked.

ICE Series  
Electrical System  
Compressor Check (Continued)  
If all starting components are good, check the voltage from the common terminal of the  
compressor, making sure proper voltage is supplied to the compressor and all wiring is properly  
connected. If the compressor does not start and there is excessive amperage draw, (see locked  
rotor amps on compressor tag) the compressor has a locked rotor and should be replaced.  
Important: Compressors returned to the factory for warranty are tested and will not be covered  
under the warranty policy if they are not defective.  
Overload (External)  
If there is no amperage draw check the compressor overload. The compressor overload can be  
checked for continuity after removing it from the compressor and letting it cool to room  
temperature. If there is no continuity between the two terminals, replace the overload. If the  
overload is suspected of opening prematurely, it should be replaced with an overload, which is  
known to be good.  
Capacitors  
The start capacitor is an electrical storage device used to provide starting torque to the  
compressor. If a start capacitor is defective, the compressor will not start properly.  
The run capacitor is an electrical storage device used to improve the running characteristics and  
efficiency of the compressor.  
Before checking a capacitor, it should be discharged by shorting across the terminals. If a run or  
start capacitor is cracked, leaking or bulging it should be replaced. If a capacitor is suspected of  
being defective, it can easily be checked by replacing it with a capacitor of the correct size, which  
is known to be good. If the compressor starts and runs properly, replace the original capacitor. A  
capacitor tester can also be used.  
Start Relay  
The start relay breaks the electrical circuit to the start windings when the compressor motor speed  
increases. If the relay is defective, the compressor will not start or it may start but will run for a  
very short time.  
A compressor relay can be checked by removing the relay and checking the relay contacts for  
damage and check for continuity across the closed relay points. Check the relay coil with an  
ohmmeter. If no continuity is read, replace the relay.

ICE Series  
Electrical System  
Untimed Freeze Cycle  
During the freeze cycle the compressor, water pump and condenser fan motor(s) (if used) are  
running. On remote systems the liquid line solenoid is also energized, see Refrigeration System.  
As ice forms on the evaporator, the suction pressure drops. The machine is in the untimed portion  
of the freeze cycle and will remain in untimed freeze until the suction pressure drops low enough to  
close the timer initiate control. See page E10-13 for operating pressures.  
Timer Initiate  
The timer initiate is a low-pressure control that closes (cut in) on a drop in suction pressure. When  
the timer initiate control closes, the freeze timer is energized and the machine enters the timed  
portion of the freeze cycle. When the machine enters harvest, the suction pressure rises and  
opens the control. The timer initiate control should be adjusted per the chart on page E10-13.  
The timer initiate is factory set and does not normally need to be adjusted. If the ice bridge  
thickness is incorrect, the freeze timer should be adjusted rather than the timer initiate. See page  
F4 for freeze timer adjustment procedure. The timer initiate may need to be adjusted if excessive  
time (more than 7 minutes) is needed on the timer to achieve proper bridge thickness of if very little  
time (less than 1 minute) is needed on the timer to achieve proper bridge thickness.  
If the timer initiate is suspected of being out of adjustment or not operating properly, check the  
control as follows. Make sure the high temperature safety control is not open, see page F8. Turn  
the machine off and disconnect incoming power by unplugging the machine or switching the circuit  
breaker OFF. Attach one lead of a voltmeter to terminal 1 and the other lead to terminal 2 of the  
timer initiate control. Reconnect incoming power and turn the machine to the ICE position.  
Connect a low pressure gauge to the machine. The volt meter should read line voltage until the  
timer initiate control closes at which point the voltmeter should read zero volts. Note the suction  
pressure at this point. Adjust the timer initiate if necessary. Turning the adjustment screw counter  
clockwise will lower the cut in pressure, turning the adjustment screw  
clockwise will raise the cut in pressure. The differential is preset and  
does not require adjustment. If the control cannot be adjusted to the  
correct pressure setting or if the cut in point is erratic the control must be  
replaced. If the suction pressure is not dropping properly, see the  
Troubleshooting Tree “Machine Does Not Enter Harvest” in Section C.  
Adjustment Screw  
Relay 1  
Relay 1 is used to energize the fan motor on air-cooled units. The fan is energized through the  
common and normally closed contacts.  
Relay 2 (Note: Relay 2 is not used on Undercounter models)  
On single evaporator machines, relay 2 is used only to bypass the bin control during the freeze  
cycle and the first part of the harvest cycle. Relay 2 is energized through the normally closed  
contacts of the cam switch at the beginning of the freeze cycle. When energized, Relay 2 will  
prevent the machine from shutting off if the bin switch opens. The relay will remain energized until  
the cam switch is lifted onto the high part of the cam during harvest. At this time the machine will  
shut off if the bin switch is open.  
Relay 3 and Relay 4 (ICE1506 Applications) Relay 3 and Relay 4 bypass the bin switches to  
allow the curtains to open and close during the freeze cycle on an ice dispenser application. This  
will prevent the ice machine from shutting off during dispenser agitation.

ICE Series  
Electrical System  
Timed Freeze  
When the freeze timer is energized, the machine  
is in the timed portion of the freeze cycle. The  
freeze timer will time out the remainder of the  
freeze cycle. Once the time has passed, the  
machine will enter the harvest cycle.  
Freeze Timer  
The freeze time is an adjustable timer used to  
control the ice bridge thickness. The freeze timer  
is factory set but may need to be adjusted upon  
initial start up of the machine. When time is  
added to the freeze timer, the length of the freeze  
cycle is increased, therefore the ice bridge  
thickness is increased. When time is removed  
from the timer, the freeze cycle is decreased and  
the ice bridge thickness is decreased.  
The freeze timer can be adjusted by sliding one  
or more switches to either the ON or OFF  
position to obtain the setting which will produce  
the proper bridge thickness. A timer setting of 128 and 256  
switched ON will provide an initial timer setting.  
Combine time in seconds  
The ice bridge thickness should be approximately 3/16”  
(5mm) on the ICEU undercounter series, ICE0250 and  
ICE0305, and 1/8” (3 mm) on ICE0400 and larger units.  
If the bridge is too thick, remove enough time from the  
timer to achieve proper thickness. If the bridge is too  
thin, add enough time to the timer to achieve proper  
thickness.  
Bridge Thickness  
Check the freeze timer for proper operation as follows: Make sure that the high temperature safety  
control is not open, see page F8. Turn the machine OFF and disconnect the incoming power by  
unplugging the machine or switching the circuit breaker OFF. Attach one lead of a voltmeter to  
terminal 1 and the other lead to terminal 3 of the timer.  
Reconnect incoming power and turn the machine to the ICE position. The volt meter should read  
zero volts until the timer initiate closes at which point the timer will energize and line voltage should  
be read.  
When the timer counts out, the voltmeter will again read zero volts. The time it takes the freeze  
timer to time out, once it has been energized should match the timer adjustment. If it does not or if  
the timer never closes, the timer is defective.  
Note: The hot gas delay timer utilized on the ICE1400, ICE1506, ICE1606, ICE1800 and  
ICE2100 Series cubers should always be set at 4 seconds. (Not applicable on Version 3)

ICE Series  
Harvest Cycle  
Electrical System  
Single Evaporator Machines  
Once the freeze timer has timed out, power is sent to relay 1 and the machine enters the harvest  
cycle. Once in harvest motor, the purge valve, hot gas valve and harvest motor are energized.  
The water pump continues to run during the first part of the harvest cycle so that mineral laden  
water remaining in the water trough can be pumped through the purge valve to the drain. The  
harvest motor turns the clutch assembly to actuate the cam switch.  
The cam switch is in the normally closed position during freeze and at the beginning of harvest.  
Once the clutch turns far enough to actuate the cam switch, the water pump and purge valve is de-  
energized. The harvest motor continues to turn the clutch. When the cam switch returns to the  
normally closed position, the machine returns to the freeze cycle.  
If the bin switch is open when the cam switch is actuated by the high part of the cam, the machine  
will shut off. Remote units pump down before shutting off.  
Relay 1  
When relay 1 is energized, the normally open contacts (1-B) close sending power to the hot gas  
valve and harvest motor and (1-A) close sends power to the purge valve and the coil of relay 1 to  
keep the coil energized when the timer initiate opens. The fan motor on self contained air cooled  
model are wired through the NC contacts of relay 1, when the contacts open during harvest, the  
condenser fan motor is de-energized.  
Relay 2 See Page F4.  
Dual Evaporator Machines  
Once the freeze timer has counter out, power is sent to: (A) harvest motor 1 and relay coil 1  
through the normally closed contacts of cam switch 1, (B) to harvest motor 2 and relay coil 2  
through the normally closed contacts of cam switch 2. The contacts of relay 1B and 2B closing,  
energizes the 4-second hot gas delay timer (Right Hand Timer)  
This 4-second delay will allow the harvest motors to rotate and allow the cam switches to switch to  
the normally open position before the low-pressure control opens during hot gas. The cam  
switches are now in the normally open position and will continue to energize the harvest motors  
and relays until the cam rotates and the switch returns to the normally closed position.  
Once the 4-second delay timer has timed out, the hot gas valves and purge valve will energize  
and allow hot gas into the evaporators. The bin control switches are by passed through the  
normally open contacts of relay 1A and 2A.  
The bin switches are bypassed to allow the cam switch to return to the normally closed position  
prior to the machine shutting down if the curtain is open. Each harvest assist motor will only make  
one revolution prior to shutting down on full bin or advancing to the next freeze cycle.  
Both hot gas valves and the water purge valve remain energized until both harvest assist motors  
complete one revolution. The water pump is energized throughout the harvest cycle. The unit will  
shut down if the curtains are open during the freeze cycle. Remote units pump down before  
shutting off. The fan motors on self contained air cooled model are wired through the NC contacts  
of relay 1B, when the contacts open during harvest, the condenser fan motors are de-energized.

ICE Series  
Electrical System  
Harvest Assist Assembly  
The harvest assist assembly  
has several purposes: to assist  
in moving the ice off of the  
evaporator, to control the  
length of harvest and to  
terminate harvest. When the  
machine enters harvest, power  
is sent to the harvest motor  
which turns a slip clutch. A  
probe is attached to the  
rotating clutch and is pushed  
against the back of the ice  
slab. The clutch begins to slip  
when the probe applies  
approximately 25 ounces of  
pressure against the ice slab.  
It takes approximately 1 minute  
for hot gas to heat the evaporator enough to loosen the ice from the evaporator plate. At this point  
the clutch pressure overcomes the capillary attraction of the ice to the evaporator plate and the ice  
begins to move off of the evaporator. As the ice is being pushed, the clutch stops slipping and  
begins to turn, extending the probe enough to push the ice completely off of the evaporator.  
Harvest Motor  
The harvest motor is energized at the beginning of harvest and will remain energized until the  
machine returns to the freeze cycle. A defective harvest motor will usually not run. The harvest  
motor rotates in a clockwise direction. It is possible for a defective motor to run backwards  
(counterclockwise). If this happens the motor must be replaced. It is also possible for a defective  
motor to “bump” backwards immediately when entering harvest. This will activate the cam switch  
and cause the machine to return to the freeze cycle immediately after entering harvest. If the  
machine is in harvest only for a split second, the harvest motor may be defective. Verify the motor  
is defective by watching the clutch closely when the machine enters harvest.  
Clutch Assembly  
The clutch assembly consists of a slip clutch and cam. A probe is attached to the clutch assembly  
and the harvest motor turns the clutch during harvest. As the harvest motor turns, the clutch will  
slip while the probe is pushed against the ice. The clutch will continue to slip as long as the  
pressure required to move the ice is greater than the 25 oz. Once the evaporator has heated  
enough to break the bond of ice to the evaporator, the pressure required to move the ice becomes  
less than the 25 oz. And the clutch begins to move.  
The clutch assembly is not adjustable. If the clutch tension is weak (less than 25 oz.) a slow  
harvest or excessive ice meltage during harvest will result. If the clutch pressure becomes too  
tight, the force of the probe against the back of the ice may cause the slab to break and the ice  
may not fall off of the evaporator. If the clutch tension is suspected of being too tight or loose, turn  
the clutch by hand. The clutch should turn smoothly without “grabbing”, but should offer some  
resistance. If in doubt as to whether or not the clutch is defective, compare the tension with one  
that is known to be good.

ICE Series  
Electrical System  
Probe Tip and Swivel  
The probe tip is attached to the clutch and makes contact with the back of the ice slab during  
harvest. The swivel allows the probe tip to pivot as the clutch turns so that the probe is pushed  
straight through the evaporator probe guide.  
The tip of the probe should be flush with the back of the evaporator or recessed up the 1/16 of an  
inch (.16cm). The probe tip must not extend into the freezing area of the evaporator during freeze.  
(Note: Units manufactured after June 2004 utilize a non adjustable probe.)  
The length of the probe is adjustable by loosening the locknut and adjusting the probe in or out of  
the swivel. Once the probe has been adjusted to the proper length, tighten the locknut. If the  
probe tip binds during operation it may cause the clutch to slip unnecessarily. This may occur if  
the harvest motor mounting bracket is not aligned properly or if the probe tip has excessive mineral  
deposits on it. Remove and clean the probe if necessary.  
To check the probe tip for binding, remove the shoulder bolt holding the swivel to the clutch and  
simulate the movement of the swivel and probe by moving the swivel in a circular motion around  
the outer portion of the clutch. The swivel should also move freely. If any resistance is felt the  
bracket should be adjusted by loosening the bracket mounting screws and repositioning the  
bracket until the probe moves freely.  
Cam Switch Operation-Single Evaporator Machines  
The actuator arm of the cam switch rides on the edge of the clutch assembly and is actuated by  
the high and low portion of the cam. When the machine is in the freeze cycle the actuator arm of  
the cam switch is in the low part of the cam. During freeze, power is supplied to the water pump  
and relay 2, through the normally closed contacts of the cam switch. When the machine enters  
harvest, power is supplied to the water pump and purge valve through the normally closed  
contacts of the cam switch and through the normally open contacts of relay 1 (closed during  
harvest). The water pump, purge valve and relay 1 remain energized until the cam switch is lifted  
on to the high part of the cam. Relay 2 will also de-energize at this time allowing the machine to  
shut off if the bin switch opens. Undercounter machines manufactured after July of 2004 will have  
the water pump run continually until the machine shuts down.  
Cam Switch Operation-Dual Evaporator Machines (Prior to January 2008)  
Once the freeze timer has counted out, power is sent to: (A) harvest motor 1 and relay coil 1  
through the normally closed contacts of cam switch 1, (B) to harvest motor 2 and relay coil 2  
through the normally closed contacts of cam switch 2.  
This 4-second delay will allow the harvest motors to rotate and allow the cam switches to switch to  
the normally open position before the low-pressure control opens during hot gas. The cam  
switches are now in the normally open position and will continue to energize the harvest motors  
and relays until the cam rotates and the switch returns to the normally closed position.  
The bin switches are bypassed to allow the cam switch to return to the normally closed position,  
prior to the machine shutting down if the curtain is open. Each harvest assist motor will only make  
one revolution prior to shutting down on full bin or advancing to the next freeze cycle.  
Both hot gas valves and the water purge valve remain energized until both harvest assist motors  
complete one revolution. The water pump is energized throughout the harvest cycle. The unit will  
shut down if the curtains are open during the freeze cycle.

ICE Series  
Electrical System  
Cam Switch Adjustment  
Check the cam switch for proper adjustment by slowing turning the clutch by hand in a  
counterclockwise direction while listening for the switch contacts to change. The switch should  
have an audible “click” as the roller reaches the high part of the cam. Now slowly turn the clutch in  
a clockwise direction and the switch should have an audible “click” as the roller reaches the low  
part of the cam. Adjust the switch by loosening the mounting screws and moving the position of  
the switch. If the cam switch is suspected of being defective it should be checked with an  
ohmmeter. It should not be assumed that the switch is good because a “click” can be heard  
when moving the actuator arm.  
High Temperature Safety Control  
The high temperature safety control is a thermal disc that protects the  
machine if the machine “sticks” in the harvest cycle. The high temperature  
safety is clamped to the suction line near the expansion valve thermal bulb.  
It opens when the suction line temperature reaches 120ºF (48.8ºC) and closes when the  
temperature drops to 80ºF (26.6ºC). If the high temperature safety opens during harvest, it will  
de-energize the harvest components. If the high temperature safety is defective and fails open  
during the freeze cycle, it will not allow the relay(s) to energize and the machine will not enter  
harvest. Remove the high temperature safety control and check it with an ohmmeter to verify that  
it is defective.  
Note 1: ICE0500R3, ICE0606R3, ICE0806R3 and ICE1006R3: The high temperature safety  
control specifications have been changed to open at 120ْF and close at 100ْF.  
Note 2: On models where the high temperature safety control is mounted on the hot gas valve  
outlet tube, the specifications are open at 180ºF and close at 120 ºF.  
Additionally the high temperature safety control is wired in series with the contactor. If the  
high temperature safety control opens for any reason, the compressor will shut down.  
This is an automatic reset control. Do not allow the machine to operate without the  
high temperature safety control. Damage to the machine may result and the  
warranty will be void.  
Bin Control Operation  
The bin control is used to shut the machine off when the bin fills with ice. The bin control must be  
checked upon installation or initial start-up and when performing maintenance. Adjustments are  
not covered under warranty.  
There is one bin switch for each evaporator. The actuator arm of the bin switch comes in contact  
with the splash curtain. When the bin is full of ice, the splash curtain is held open when ice drops  
off of the evaporator. This releases the pressure of the bin switch actuator arm allowing the switch  
to open.  
Single evaporator machines: If the bin switch opens during freeze, or the first part of harvest,  
relay 2 bypasses the bin switch and the machine will continue running. If the bin switch is opened  
during harvest, when the cam switch is lifted onto the high part of the cam, the machine will shut  
off. When the bin switch closes again, the machine will restart.  
Dual evaporator machines: If either bin switch opens during the freeze cycle, the machine will  
shut off. Relay 1 and relay 2 will bypass the bin switches during defrost. If either bin switch is  
open when the machine returns to the freeze cycle, the machine will shut off.

ICE Series  
Electrical System  
Undercounter machines: A thermostatic bin control is used on the undercounter models. The bin  
thermostat is located in the control box with a capillary tube, which is in a brass thermo-well  
mounted to the water trough. When ice comes in contact with the capillary tube thermo-well, the  
bin thermostat opens and the machine will shut off.  
Bin Control Adjustment  
All Models (Except Undercounter Models): Check the bin switch for proper adjustment by  
swinging the bottom of the curtain away from the evaporator. Slowly bring the curtain towards the  
evaporator. The switch should close when the bottom edge of the curtain is even with the outer  
edge of the water trough. Adjust the switch by loosening the screws the hold the switch in place.  
Move the switch to the proper position and retighten the screws. Recheck the adjustment.  
Adjustments are not covered under warranty.  
Undercounter Models  
Turn the machine to the ICE or WASH position. Hold ice against the brass thermal-well mounted  
to the water trough making sure the ice is in contact with at least 6 inches (15 cm) of the thermal-  
well. The machine should shut off in approximately 1 minute, remove the ice, the machine should  
restart in approximately 3 minutes. If a major adjustment is required, turn the adjustment screw  
counterclockwise (warmer) until it stops then turn the adjustment screw clockwise (colder) 1/8 of a  
turn. This should put the control close to the proper adjustment, recheck and make a minor  
adjustment if needed. If a minor adjustment is required, turn the adjustment screw clockwise  
(colder) or counterclockwise (warmer). Adjustments are not covered under warranty.  
Pump Down System (Remote Only)  
If a remote machine is shut down by the selector switch or bin control, the liquid line solenoid valve  
is de-energized allowing the valve to close. This blocks the flow of refrigerant causing all the  
refrigerant to be pumped into the receiver and condenser. This is done to prevent liquid refrigerant  
from migrating into the compressor during the off cycle, which could damage the compressor on  
start-up. Also see Pump Down System in the Refrigeration Section on page E7. As the refrigerant  
is pumped into the receiver, the suction pressure begins to drop. Once the suction pressure  
reaches approximately 10 psi (.68 bar) the pump down control contacts open, which will de-  
energize the compressor contactor. When the machine is turned back on, power is supplied to the  
liquid line solenoid which opens the valve and allows the suction pressure to rise enough to close  
the pump down controls contacts.  
Pump Down Control  
The pump down control is a low pressure control that shuts the machine off when the  
suction pressure drops during the pump down phase. The control is factory set to open at  
10 psi (.68 bar) and close at 30 psi (2.04 bar). The pump down control does not normally  
need to be adjusted, however an adjustment may be made by turning the adjustment  
screw. Note: Later model machines have a non adjustable pump down control.  
Fan Control  
On models utilizing a fan control, the fan will cycle on at 250 psi (17.01) and  
cycle off at 200 psi (13.61 bar).
