1-4 Responsibility
These machines are constructed for maximum operator safety when used under standard
operating conditions and when recommended instructions are followed in the maintenance
and operation of the machine.
All personnel engaged in the use of the machine should become familiar with its operation as
described in this manual.
Proper operation of the machine promotes safety for the operator and all workers in its
vicinity.
Each individual must take responsibility for observing the prescribed safety rules as outlined.
All warning and danger signs must be observed and obeyed. All actual or potential danger
areas must be reported to your immediate supervisor.
General Responsibility
No mater who you are, safety is important. Owners, operators and maintenance personnel
must realize that every day, safety is a vital part of their jobs.
If your main concern is loss of productivity, remember that production is always affected in a
negative way following an accident. The following are some of the ways that accidents can
affect your production:
• Loss of a skilled operator (temporarily or permanently)
• Breakdown of shop morale
• Costly damage to equipment
• Downtime
An effective safety program is responsible and economically sound.
Organize a safety committee or group, and hold regular meetings. Promote this group from
the management level. Through this group, the safety program can be continually reviewed,
maintained, and improved. Keep minutes or a record of the meetings.
Hold daily equipment inspections in addition to regular maintenance checks. You will keep
your equipment safe for production and exhibit your commitment to safety.
Please read and use this manual as a guide to equipment safety. This manual contains safety
warnings throughout, specific to each function and point of operation.
Operator Responsibility
15, 30, & 60 cfm Compact Dryers

Download from Www.Somanuals.com. All Manuals Search And Download.
The operator’s responsibility does not end with efficient production. The operator usually has
the most daily contact with the equipment and intimately knows its capabilities and
limitations.
Plant and personnel safety is sometimes forgotten in the desire to meet incentive rates, or
through a casual attitude toward machinery formed over a period of months or years. Your
employer probably has established a set of safety rules in your workplace. Those rules, this
manual, or any other safety information will not keep you from being injured while operating
your equipment.
Learn and always use safe operation. Cooperate with co-workers to promote safe practices.
Immediately report any potentially dangerous situation to your supervisor or appropriate
person.
REMEMBER:
• NEVER place your hands or any part of your body in any dangerous location.
• NEVER operate, service, or adjust the dryer without appropriate training and first
reading and understanding this manual.
• NEVER try to pull material out of the dryer with your hands while it is running!
• Before you start the dryer check the following:
• Remove all tools from the dryer;
• Be sure no objects (tools, nuts, bolts, clamps, bars) are laying in the
hopper area;
• If your dryer has been inoperative or unattended, check all settings before starting the
unit.
• At the beginning of your shift and after breaks, verify that the controls and other
auxiliary equipment are functioning properly.
• Keep all safety guards in place and in good repair. NEVER attempt to bypass, modify,
or remove safety guards. Such alteration is not only unsafe, but will void the warranty
on your equipment.
• When changing control settings to perform a different mode of operation, be sure
selector switches are correctly positioned. Locking selector switches should only be
adjusted by authorized personnel and the keys removed after setting.
• Report the following occurrences IMMEDIATELY:
• unsafe operation or condition
• unusual dryer action
• leakage
• improper maintenance
• NEVER stand or sit where you could slip or stumble into the dryer
while working on it.
• DO NOT wear loose clothing or jewelry, which can be caught while working on a
dryer. In addition, cover or tie back long hair.
• Clean the dryer and surrounding area DAILY, and inspect the machine for loose,
missing or broken parts.

• Shut off power to the dryer when it is not in use. Turn the switch to the OFF position,
or unplug it from the power source.
Maintenance Responsibility
Proper maintenance is essential to safety. If you are a maintenance worker, you must make
safety a priority to effectively repair and maintain equipment.
Before removing, adjusting, or replacing parts on a machine, remember to turn off all electric
supplies and all accessory equipment at the machine, and disconnect and lockout electrical
power. Attach warning tags to the disconnect switch.
When you need to perform maintenance or repair work on a dryer above floor level, use a
solid platform or a hydraulic elevator. If there is a permanently installed catwalk on your
equipment, use it. The work platform should have secure footing and a place for tools and
parts. DO NOT climb on dryers, machines, or work from ladders.
If you need to repair a large component, use appropriate handling equipment. Before you use
handling equipment (portable “A” frames, electric boom trucks, fork trucks, overhead cranes)
be sure the load does not exceed the capacity of the handling equipment or cause it to become
unstable.
Carefully test the condition of lifting cables, chains, ropes, slings, and hooks before using
them to lift a load.
Be sure that all non-current carrying parts are correctly connected to earth ground with an
electrical conductor that complies with current codes. Install in accordance with national and
local codes.
When you have completed the repair or maintenance procedure, check your work and remove
your tools, rigging, and handling equipment.
Do not restore power to the dryer until all persons are clear of the area. DO NOT start and
run the dryer until you are sure all parts are functioning correctly.
BEFORE you turn the dryer over to the operator for production, verify all dryer enclosure
panels, guards and safety devices are in place and functioning properly.
Reporting a Safety Defect
If you believe that your equipment has a defect that could cause injury, you should
immediately discontinue its use and inform the manufacturer.
The principle factors that can result in injury are failure to follow proper operating procedures
(i.e. lockout/tag out), or failure to maintain a clean and safe working environment.

Chapter 2: Functional Description
2-1 Models Covered in This Manual
This manual provides operation, installation, and maintenance instructions for 15, 30 and 60
cfm dehumidifying dryers. Model numbers are listed on the serial tag. Make sure you know
the model and serial number of your equipment before contacting the manufacturer for parts
or service.
Our dehumidifying mini dryers are designed to generate heated dehumidified air (at a very
low dew point) at carefully controlled temperatures for use in plastic drying systems. The
dryer circulates hot air through a column of plastic resin in the large drying hopper. The resin
in the hopper is discharged through a slide gate in a “first in, first out” manner.
2-2 General Description
The Drying System
Dehumidifying dryers are used to generate very low dew point air heated to a controlled
temperature for drying plastic pellets and regrind.
Our dryers force hot, dry air through resin in a drying hopper, where air picks up moisture
from the material and draws it back to the dryer. In the dryer, a desiccant bed strips moisture
from the air. The dried process air is then re-heated and delivered back into the drying
hopper for more moisture removal.
Portion of the low dew point process air is directed to the desiccant tank that is off process.
This air is heated to approximately 450°F (232°C) before entering the bed that is in
regeneration. The moisture is then forced from the desiccant before being exhausted into the
atmosphere. A small amount of ambient air is introduced into the process return air filter to
make up for the air lost during the bed regeneration. To compensate for the humidity content
in the air, this dryer is supplied with the proper amount of desiccant.
What is desiccant?
Desiccant is a material that attracts and holds (absorbs) water from the air. The desiccant our
dryers use is a synthetic crystalline metal aluminosilicate blended with a clay binder and
formed into beads.
The Process/Regeneration Cycle
Our dryers have two desiccant beds. While one bed is on-line in the process air loop, the
other is off-line, being regenerated.
When a desiccant bed is on-line, it absorbs moisture from the process air. In time, the bed
becomes saturated with moisture and needs to be regenerated. The dryer automatically
redirects the process airflow to the second bed, and starts the regeneration cycle on the first
bed.
During regeneration, the dryer system heats the very low dew point air and forces it through
the desiccant bed. The moisture driven off the bed bleeds to the atmosphere.

Safety Circuit Standards
Safety circuits used in industrial systems protect the operator and maintenance personnel
from dangerous energy. They also provide a means of locking out or isolating the energy for
servicing equipment.
Various agencies have contributed to the establishment of safety standards that apply to the
design and manufacture of automated equipment. The Occupational Safety and Health
Administration (OSHA) and the Joint Industrial council (JIC) are just a few of the
organizations that have joined with the plastics industry to develop safety standards.
Every effort has been made to incorporate these standards into the design of the drying
system; however, it is the responsibility of the personnel operating and maintaining the
equipment to familiarize themselves with the safety procedures and the proper use of any
safety devices.
Fail Safe Operation
If a safety device or circuit should fail, the design must be such that the failure causes a
“Safe” condition. As an example, a safety switch must be a normally open switch. The switch
must be held closed with the device it is to protect. If the switch fails, it will go to the open
condition, tripping out the safety circuit.
At no time should the safety device fail and allow the operation to continue. For
example, if a safety switch is guarding a motor, and the safety switch fails, the motor should
not be able to run.
Safety Device Lock-Outs
Some safety devices disconnect electrical energy from a circuit. The safety devices that are
used on these dryers are primarily concerned with electrical power disconnection and the
disabling of moving parts that may need to be accessed during the normal operation of the
machine.
Some of the safety devices utilize a manual activator. This is the method of initiating the
safety lock out. This may be in the form of a plug, lever or a handle. Within this lockable
handle, there may be a location for a padlock. Personnel servicing the equipment should
place a padlock in the lockout handle.
In addition to the safety devices listed above, these dryers are equipped with a line cord plug.
This allows the operator or maintenance personnel to unplug the dryer from its power source
and tag it out. The plug can then be tagged with any number of approved electrical lockout
tags available at most electrical supply stores.
WARNING! Always disconnect and lockout all electrical power and pneumatic (i.e. compressed air)
sources prior to servicing or cleaning the dryer. Failure to do so may result in serious
injury. No one but the person who installed the lockout may remove it.

4. Lower slowly.
3-2 Rigging and Placing the Dryer
Take care when rigging and placing the dryer. Figures 1, 2 and 3 on the following pages show
a suggested safe rigging diagram. It lets you lift the dryer/hopper unit vertically for
installation on the machine throat. Adjust chain lengths at the center sling bracket before you
lift the unit. Your dryer has built-in lifting lugs.
Caution!
If you are mounting a machine-mount dryer with a magnet or transition adaptor on the
machine throat, you must provide additional support to hold the dryer securely on the
machine.
Be aware that off-center static and dynamic hopper loading can occur with machine
vibration. Again, provide additional support to hold the dryer securely on the machine.
Use caution and observe safety rules when lifting and placing your dryer!

3-3 Electrical Connections
When making electrical connections to your dryer, ensure that you take into consideration
and make arrangements for the following:
• A qualified electrician should make all electrical connections.
• Fulfill all national, state, and local safety and electrical code requirements.
• The serial tag lists voltage, phase, and amp draw information:
• Line voltage must be within plus or minus ten percent (±10%) of the
voltage listed on the serial tag, or damage may occur. Phase imbalance
must be less than two percent (2%).
• Connect main power to the dryer at the disconnect or terminals in the upper right
corner of the control enclosure.
• Install a fused disconnect with a lockout feature in the power main leading to the dryer.
• The power drop must include a ground wire.
• Make sure all electrical connections are tight.

3-4 Setup Procedures
This section provides the procedures necessary for configuring your Dehumidifying Dryer.
Configuration of your dryer includes checking for proper blower rotation, making
dryer/drying hopper process air connections and the optional aftercooler (on 15 and 30 cfm
models). We recommend that you carry out these procedures in the order given here.
Note: Before carrying out these procedures, install all equipment as
described in this section.
Checking for Proper Blower Rotation
Three-Phase Models
Caution!
In three-phase models, incorrect phasing of power leads can cause
backward rotation of blower motors and CONTAMINATION OF THE
DESICCANT!
Always check blower rotation before putting material in the drying hopper!
The blower is rotating properly when air flows from the delivery outlet.
Note: Holding your hand in front of the air return will also indicate if the
blower rotates in the proper direction.
If the three-phase blower rotates improperly, reverse any two wires at the fused disconnect
outside the dryer or at the disconnect/terminal in the control enclosure. This assures that the
blower rotates in the proper direction.
Making Dryer/Drying Hopper Process Air Connections
Floor Mount Models
When making process air connections to your floor mounted dryer, ensure that you take into
consideration and make arrangements for the following:
• Use high-temperature flexible dryer hose or rigid tubing to connect the dryer to the
drying hopper.
• Keep the delivery hose to the drying hopper as short as possible to minimize heat loss.
We strongly recommend insulated hose for maximum energy savings.
• Do not use insulated hose on the return from the drying hopper.
• The return air to the blower must be 150°F (66ºC) or below. If the return air
temperature is not below this point, you should purchase and install the optional
aftercooler to remove excessive heat. Consult the manufacturer for more information.
Aftercooler considerations also apply to machine-mount models.
• Make sure that hoses are not kinked or collapsed.
• Drying hopper air inlet and outlet locations vary, but always connect hoses so the dry
process air from the dryer enters the bottom of the drying hopper and flows out the top
to return to the dryer inlet.
• Thermocouple is to be installed at drying hopper’s delivery tube.

Drying Hopper Air Trap Considerations
Our exclusive air trap assembly on the top of the drying hopper prevents ambient air from
contaminating the material being dried. To ensure that your unit will operate at peak
efficiency, do the following:
• Keep the material level at the mid point of the air trap
This can be achieved by utilizing a hopper loader or vacuum conveying system to
supply material to the drying system.
Optional Aftercooler
Water-cooled 15 and 30 cfm models use a water-to-air heat exchanger as an aftercooler.
Cooling water is required for this design (3 gpm at 85°F or lower). Return air from the
hopper passes through the air filter to trap fines and dust before entering the heat exchanger.
Installing Water Lines
(Hose and Hose Clamp)
When installing the water lines, ensure that the aftercooler utilizes either tower, chilled or city
water up to 85°F (29°C). Recommended flow rate is three (3 gpm) gallons per minute (11
liters per minute).
3-5 Initial Start-up
Pre-Startup Checks
; Check the process and return hoses for tight connections.
; Check all companion equipment, such as the drying hopper; verify that the loading
system is ready for operation.
; Verify that all dryer electrical connections are tight.
Caution!
Clean the rust-preventing oil from inside the drying hopper.
Failure to clean the hopper fouls the desiccant and voids your warranty!
; Verify that the dryer’s thermocouple is properly connected in the center of the drying
hopper’s delivery tube.
; Verify that the temperature control has been configured for your specified scale (ºF
or ºC).
Starting Up the Dryer
1. Turn on (energize) the disconnect switch in your power drop, then turn on the
disconnect switch on the dryer (3 phase only).
2. Turn the system ON/OFF switch to ON to start the dryer.
3. Close the slidegate at the bottom of the drying hopper.
Make sure that the blowers turn in the right direction.
4. Fill the drying hopper with material. Dryer performance is compromised if hopper is
not full!
5. If your dryer has a water-cooled aftercooler, make sure that sufficient cooling water
(3gpm at 85°F or lower) flows properly through the coil and that you have bled any
15, 30, & 60 cfm Compact Dryers

trapped air from the system. Make sure the aftercooler has the proper supply water
temperature.
6. Set the process set point on the temperature controller.
7. After the proper pre-drying time for the initial hopper fill has elapsed, fully open the
drying hopper slide gate.
Note: To allow proper residence time during continuous processing,
maintain the material level in the hopper at the midpoint of the air trap
assembly.
Auto-Tuning the Dryer
1. For Auto-tuning, press the Level Key once. The AT screen will show
with the setting OFF.
2. Press UP arrow to change the setting to ON.
3. Press the Level Key again to the Temperature Screen. Your actual
temperature will start to flash for about 10-20 minutes with the
temperature fluctuating up and down during that period. After the
flashing stops, it means auto-tuning has finished.
Shutting Down the Dryer
1. Turn off the conveying system supplying the drying hopper.
2. When processing is complete, close the hopper slide gate and shut down any in-line

Process Air Temperature Controller
Our dryers use a microprocessor-based PID temperature controller for maintaining process air
temperature. The controller is a modular, self-contained unit you can remove from the
mounting housing. All parameters except for the process air set point are factory set and
adjusted; normally, no field adjustment to the internal controls is necessary.

4-2 Dryer Operation Procedures
Controller Operation
1. Turn the disconnect (if applicable) on the control panel to the ON position. Power is
applied to the voltage line fuses, line side of the control power switch.
2. Turn the control power switch to the ON position. Power is applied to the
temperature control, programmable relay and dew point controller. The valve will
move to the start position as follows:
a. The valve motor rotates until the cam switch makes 2 transitions.
b. If the cam switch does not make a transition within 10 seconds, a valve
motor fault is generated. “VALVE MTR” is displayed on the relay screen,
the alarm light is activated. The valve motor, heaters, and blower shut off.
To restart the dryer, cycle control power to deactivate the alarm light and
restart the valve motor sequence.
Note: The relay screen which contains the Alarm Display Messages is located
inside the controller enclosure. For a list of Alarm Display Messages,
see Page 32.
WARNING! Do not attempt to check the Alarms on the Controller located within the
unit enclosure unless you are a qualified electrician!
c. The valve will normally complete one full cycle (revolution).
If the drying process shuts down due to an alarm, the dryer has been setup to
have the following operational features:
• The bed in process at power-down will remain in process.
• The bed in regeneration at power-down will remain in regeneration.
• The regeneration timing cycle will restart from the beginning.
3. Once the control power is on and no fault conditions exist, the dryer will start as
follows:
a. The process/regen blower is started.
b. The process heater is turned on and controlled by the E5CN controller.
c. The regen heater is turned on and the regeneration timing sequence is
initiated. For default timing settings for regeneration, see the table below.

5-2 Preventative Maintenance
This section describes maintenance procedures which will increase the longevity and
efficiency of your dehumidifying dryer. Perform them at the regular intervals listed on the
dryer checklist on the previous page.
Servicing Process Air Filters
Caution!
Operating the dryer without the process air filter installed voids your
warranty!
Filter cleaning is an important part of your dryer maintenance program.
Dehumidifying dryers have a single cartridge canister-type filter in the process air loop. The
filter protects blowers from plastic fines drawn in from the drying hopper and prevents the
desiccant from being contaminated. Regular filter cleaning is essential to keep your dryer
operating at peak efficiency.
You can blow or vacuum the dirt out of the filter with compressed air, but remember, it could
become damaged from high-pressure blowing.
Recommendations for Cleaning and Replacing Filters
• Turn off and/or lock out electrical power to the dryer.
• Remove the threaded fastener securing the filter access cover, then remove the cover.
• Remove the nut on the center retaining rod to remove the filter cartridge.

Vacuuming
Try vacuum-cleaning a soiled filter first. Vacuuming removes most large particles and
surface contaminants, and may suffice for the first time you clean a filter. Use a commercial-
duty (recommended) or household vacuum cleaner. Vacuum the filter from the air intake
(dirty) side only.

Cleaning with Compressed Air
Blow clean, dry compressed air up and down the pleats, blowing out the filter
from the inside out. Remove loose dirt from the filter with compressed air or
vacuum from the outside.
Caution!
DO NOT clean/wash filter with water!
After each cleaning:
• Inspect the filter element. Briefly hold a light bulb behind the element
and look for any fatigued paper or residual dirt. Inspect for holes and
tears by looking though the filter toward a bright light. Check for
damaged gaskets or dented metal parts. Do not re-use a damaged
filter!
• Check the gasket for damage. A damaged gasket allows contaminants
into the process. Replace as needed.
Servicing the Dew Point Monitor
The accuracy of the dew point monitor on mini dryer systems depends on proper operation of
the dew point sensor and the control board. The dew point sensor is in the process air stream
and is therefore susceptible to contamination.
Dew point sensor life depends on:
• Air temperature and flow passing over the sensor.
• The amount of fines (dust) in the process air.
• The amount of plasticizer vapor in the process air.
Once every six months, the dryer operator should monitor the initial dew point sensor
readings and establish a periodic replacement schedule as needed.
Caution!
Do not attempt to check the continuity or resistance of the dew point
sensor.
5-3 Corrective Maintenance
This section provides you with the information necessary to correct or repair any issues
which might appear during the normal operation of your dehumidifying dryer. Although we
have listed how to perform these procedures, it is recommended that you call the Service
Department to have any in-depth maintenance performed.
Symptoms of Worn Desiccant
The moisture absorption capacity of the desiccant used in your dehumidifying dryer degrades
after an indefinite period of time. Useful life depends on variables such as the condition of the
process filter, how much dust and fines have been passed through the filter and got into the
desiccant chamber, and plasticizer vapors in the return air.

WARNING! Handling desiccant material is HAZARDOUS.
Wear an N-100 type safety filter mask or equivalent to avoid prolonged
breathing of desiccant dust. Wear safety goggles and gloves to avoid
contact with eyes and skin.
• Handle with adequate ventilation.
• Wash hands thoroughly after handling.
+ FIRST AID +
In case of eye contact, immediately flush eyes
with plenty of water for at least 15 minutes.
SEE A PHYSICIAN IMMEDIATELY IF IRRITATION PERSISTS.
Replacing Worn Desiccant
Caution!
DESICCANT BEDS ARE HOT DURING OPERATION.
To avoid burn hazard, make sure desiccant beds are sufficiently cool
before replacing worn desiccant.
To access the Desiccant Bed:
1. Disconnect electrical power to the dryer.

Chapter 6: Troubleshooting
6-1 Introduction
The utmost in safety precautions should be observed at all times when working on or around
the machine and the electrical components. All normal trouble-shooting must be
accomplished with the power off, line fuses removed, and with the machine tagged as out of
service.
The use of good quality test equipment cannot be over-emphasized when troubleshooting is
indicated. Use a good ammeter that can measure at least twice the AC and DC current that
can be encountered for the machine. Be sure that the voltmeter has at least minimum
impedance of 5,000 OHMS-per-volt on AC and 20,000 OHMS-per-volt on DC scales.
Popular combination meters, VOM and VTVM can be selected to provide the necessary
functions.
Before making haphazard substitutions and repairs when defective electrical components are
malfunctioning, we recommend that you check the associated circuitry and assemblies for
other defective devices. It is common to replace the obviously damaged component without
actually locating the real cause of the trouble. Such hasty substitutions will only destroy the
new component. Refer to wiring diagrams and schematics.
Locating mechanical problems, should they occur, is relatively straightforward. When
necessary, refer to the parts catalog section.

6-2 Determining Temperature Controller Errors or Sensor Errors
Using a Thermocouple
If the controller displays a temperature that is close to room temperature (70ºF/21ºC) when
you short-circuit controller input terminals, the controller is normal and the sensor is probably
broken, short-circuited, or incorrectly wired.
Other service problems or questions can be answered by contacting the Service
Department.

Chapter 7: Appendix
7-1 Warranty
Unless otherwise specified, this product includes a Standard ONE YEAR PARTS
WARRANTY.
Warranty Specifications
The manufacturer hereby expressly warrants all equipment manufactured by it to be free from
defects in workmanship and material when used under recommended conditions, as set forth
in the operating manuals for such equipment. THE FOREGOING EXPRESS WARRANTY
IS EXCLUSIVE AND IN LIEU OF ALL OTHER WARRANTIES, GUARANTIEES,
AGREEMENTS, AND SIMILAR OBLIGATIONS OF THE COMPANY AND/OR
MANUFACTURER (UNLESS OTHERWISE SPECIFIED IN THE SPECIFIC PRICE
PAGE OR LIMITED BY THE MANUFACTURERS’ WARRANTY FOR PARTS). The
Company’s obligation is limited to repair or replace FOB the factory any parts that are
returned, prepaid, within one year of equipment shipment to the original purchaser, and
which in the Company’s opinion, are defective. Any replacement part assumes the unused
portion of this warranty.
Warranty Restrictions
This parts warranty does not cover any labor charges for replacement of parts, adjustment
repairs, or any other work. This warranty does not apply to any equipment which, in the
Company’s opinion, has been subjected to misuse, negligence, or operation in excess of
recommended limits, including freezing or which has been repaired or altered without the
Company’s express authorization. If the serial number has been defaced or removed from the
component, the warranty on that component is void. Defective parts become the property of
the warrantor and are to be returned immediately, without any further use or handling.
Warranty Liabilities
THE COMPANY EXPRESSLY DISCLAIMS ANY AND ALL LIABILITY FOR ANY
SPECIAL, CONSEQUENTIAL OR INCIDENTAL DAMAGES OR EXPENSES THAT
RESULT FROM THE USE OF THIS PRODUCT. Some states do not allow the exclusion or
limitation of special, consequential or incidental damages, so the above limitation may not
apply to you. The Company’s obligation for parts not furnished as components of its
manufactured equipment is limited to the warranty of the manufacturers of said parts. The
company neither assumes nor authorizes any other persons to assume for it any liability in
connection with the sale of its equipment not expressed in this warranty. No person, agent,
manufacturer, distributor, dealer, installer or company is authorized to change, modify or
extend the terms of this warranty in any manner whatsoever.
The time within which an action must be commenced to enforce any obligation of the
Company’s arising under this warranty, or under any statute or law of the United States or
any state thereof, is hereby limited to the duration of this warranty. Some states do not permit
this limitation, so the above may not apply to you. This warranty gives you specific legal
rights and you may also have other rights which vary from state to state. For transactions
involving the potential applicability of international law or that of a foreign country,
this warranty policy and the procedures hereunder shall be governed by
applicable federal and state law, but not by the United Nations Convention on Contracts for
the Sale of Goods.
