INSTALLATION:  
INSTALLATION CLEARANCES:  
The fryer needs clearance around it to allow for correct combustion, cleaning and for fire hazard reasons. It is  
recommended that the fryers have a minimum of 15 cm of clearance from any combustible surface and have at  
least 15 cm floor clearance. If the fryer is equipped with a filter, it will be necessary to allow at least 0.75 m front  
clearance for the removal/installation of the filter pan/module.  
VENTILATION & FIRE SAFETY SYSTEMS:  
All fryers must be placed under a Hood style ventilation system. An adequate supply of fresh air shall be provided  
into the room or space enclosing equipment for the units ventilation and combustion requirements. Exhaust gases  
can reach high temperatures, therefore, it is important to install a fire safety system. Both the Ventilation Hood  
and Fire Safety System must be installed according to local and national codes.  
GAS CONNECTION:  
NEVER supply the fryer with a gas that is not indicated on the data plate, located on the inside of the door. To  
ensure peak performance and correct combustion Pitco Fryers must be supplied with an amount of Fuel Gas  
sufficient to meet the rating requirements shown on the data plate, found on the inside of the door. All gas  
connections must be made by a Certified Gas Service Technician.  
FUEL LINE TESTING:  
Since the internal gas valve of the Pitco Fryer is rated at 50 mbar maximum pressure, it is imperative that no  
testing be done at a pressure greater than this. If it is necessary to test at a pressure greater than this, the fryer  
should be isolated from the gas line so that damage to the gas valve does not occur.

INITIAL ASSEMBLY:  
Remove the two (2) screws that mount the rear of the tank to the cabinet. Place the Flue Heat Deflector in place  
with the bend facing forward. Replace the tank mounting screws, through the Flue Heat Deflector into the tank. In  
some cases the fryers legs may need to be installed.  
ELECTRICAL CONNECTIONS: (Some machines do not require an electrical connection)  
Pitco Frialators are manufactured to run on a particular electrical supply. Do NOT attempt to connect any fryer to  
an electrical supply that is not indicated on the data plate on the inside of the door. All electrical connections must  
be made according to the local codes and regulations .  
INITIAL ADJUSTMENTS:  
Thermocouple: The pilot is set at the factory and requires NO further adjustment.  
Gas Pressure (Only when Governors are installed.): The gas pressure should be adjusted until the manifold  
pressure reads the same pressure that is indicated on the data plate, located on the inside cover of the door.  
Air Pressure (RPB14 ONLY): Use a pressure gauge capable of measuring under 3 mbar. Adjust the air pressure  
at each burner supply elbow to 2.21 mbar by adjusting the air slides at the blower.  
Regulating Thermostats: These are preset at the factory and DO NOT need further adjustment. Do NOT attempt  
to make adjustments to this device.  
Hi Limit Thermostats: These are preset at the factory and DO NOT need further adjustment. Do NOT attempt to  
make adjustments to this device.  
INITIAL CLEANING:  
Before filling any Pitco Frialator with oil, it is advised that it be thoroughly cleaned to remove any foreign particles  
from the cooking area. The machine should be filled with water to at least, the minimum level. Add the sample  
packet of Fryer Cleaner and set the temperature control between 90º and 100º C. Using the supplied brush and  
the appropriate protective clothing, brush the inside of the fry tank until clean. When finished, turn the machine  
OFF and drain, rinse the tank with fresh water and dry carefully. The machine should be filled with oil at this time  
and all exposed surfaces coated with a small amount of cooking oil to prevent surface rust.  
OPERATION:  
COVERS:  
In case of an oil fire in the fryer the cover can be used to place on top of the fryer to extinguish the flames. It  
should be kept in a nearby location that is uncluttered and easy to reach.  
FILLING THE FRY TANK WITH SHORTENING:  
When using solid shortening, it must be cut into approximately 3 cm cubes and loosely packed around each of  
the heat tubes. Be careful not to obstruct the optional float switch. If installed, it will be located in the bottom of the  
fry tank at the rear as it must be allowed to float freely. Check that the oil level is at the minimum level once the oil  
has melted.  
LIGHTING THE PILOT:  
On NON Electronic Ignition Fryers: Turn the gas valve knob to the PILOT position and press inward. Light the  
pilot flame. Continue to press the gas valve knob for approximately 15 to 30 seconds. The pilot should remain lit  
when the gas valve knob is released, if NOT, try to reset the Hi-Limit and relight the pilot.  
On Electronic Ignition Equipped Fryers: The pilot does NOT require lighting, since the machine will do this  
automatically.  
RUNNING THE FRYER UP TO OPERATING TEMPERATURE:  
GS Thermostat Equipped (The Thermostat is connected to the Gas Valve by 2 small gas lines): Turn the gas  
valve knob to the ON position and turn the Thermostat Dial to the desired level. The burners will automatically  
bring the oil up to the cooking temperature. You may now cook with your Pitco fryer.  
Digital Thermostat Equipped: Turn the gas valve knob to the ON position and press the ON/OFF switch on the  
Display. The Digital control will illuminate and bring the shortening up to the desired temperature. You may now  
cook with your Pitco fryer.  
Computer Equipped: Turn the gas valve knob to the ON position and press the Switch to the ON position. The  
computer display will come on and automatically bring the temperature up to the desired level and display  
READY. You may now cook with your Pitco fryer.

CLEANING / MAINTENANCE:  
DAILY CLEANING:  
Using a soft cloth and a mild detergent, wipe all external surfaces until they are free of debris. It is permissible to  
allow a thin film of cooking oil to remain on all exposed (NON PAINTED) surfaces. Be sure to clean the front  
panel and behind the door.  
WEEKLY CLEANING:  
Turn the gas valve knob to the PILOT position. The fryer should be completely drained of shortening. Fill the fry  
tank with water to above the minimum and below the maximum level lines. (For best results use Pitco Fryer  
Cleaner Part Number P6071397.) Turn the fryer ON as described in the "RUNNING THE FRYER UP TO THE  
OPERATING TEMPERATURE:" section. When the water boils, use a pair of insulated rubber gloves and the  
supplied cleaning brush (35C+ fryers are economy models and are not supplied with cleaning brush) to scrub the  
inside of the fry tank, taking care not to damage the thin capillary tubes inside the tank. When the fryer is clean,  
shut the fryer down as described in the "SHUTTING THE FRYERS DOWN FOR A SHORT PERIOD:" section.  
Drain the water into a container that is capable of withstanding boiling water. Rinse the inside of the tank with  
fresh water and dry with a soft cloth until all of the water is gone. This is a good time to perform the DAILY  
CLEANING. The fryer is now ready to be refilled and used.  
OPTIONS:  
There are many options available on Pitco Frialator Fryers, these may include one or more of the following:  
DIGITAL CONTROLS:  
Machines with this option are completely controlled by the Digital Control. For programming instructions, refer to  
the Operating section of this manual.  
COMPUTERS:  
All machines manufactured with the Computer option have a Back Up Thermostat. This Thermostat is located  
behind the door of the fryer. When the computer receives an Open Probe signal from the Temperature Sensing  
Probe, the Computer will display PROBE and the Back Temperature control will automatically begin to control the  
oil temperature. For programming instructions, refer to the Operating section of this manual.  
FLOAT SWITCH:  
Take care to keep the Float Switch Ball free of any obstructions and debris as this will effect the way the fryer will  
operate. When cleaning the Float Ball, the Clip must be removed first to provide access to the Float Ball. When  
replacing the Float Ball make sure the Stamped letters are on the top. This option requires no other operator  
maintenance.  
BASKET LIFTS:  
On machines that are equipped with Computers or Digital Controls, the Basket Lifts will automatically run when a  
product button is pressed. When the Product Cook Time has expired the Basket Lifts will raise automatically.  
UFM OR BUILT IN FILTER (F) OPERATION:  
Filter paper should be changed when it is no longer effectively filtering the operating oil. For instructions on how to  
filter, please refer to the Operating section of this manual.

SERVICE  
This chapter provides the qualified technician with the trouble shooting techniques necessary to diagnose  
individual components within the Pitco fryer.  
Thermostats:  
GS (The Thermostat is connected to the Gas Valve by two small tubes): This type of thermostat has an open port  
when the temperature at the probe is LESS than the Set temperature. When the temperature is above the Set  
level the port becomes closed. If Gas is leaking through the port the Thermostat must be replaced. If the  
thermostat will not calibrate or maintain calibration within ±5ºC it should be replaced.  
Gas Valves:  
GS (The Thermostat is connected to the Gas Valve by two small tubes): Turn the Pilot Knob the PILOT position.  
Remove the Outlet tube from the gas valve actuator. Seal the Outlet port at the gas valve. Turn the Pilot Knob the  
ON position. With the Outlet Port sealed the main burners should not come ON, release the seal and the main  
burner should come ON. Cycle the Gas Valve several times. If the Gas Valve does not perform as expected it  
should be replaced.  
Electric Actuated: Test for Voltage at the wires on the Gas Valve Actuator. If voltage IS present and the valve  
Actuator does NOT operate (Usually a small sound can be heard as the Actuator moves) the Gas Valve should  
be replaced. If the Actuator operates but the main burners still do not come ON the Actuator should be removed  
and inspected. If any part of the Actuator is damaged it should be replaced.  
Electronic Ignition: These Gas Valves use Electric Actuators which should be diagnosed as described in the  
above section. These Gas Valves also use a small solenoid, mounted on the side of the body of the valve, to  
control the flow of gas to the pilot. Test for 24 vac between the wires at the solenoid, if voltage IS present and NO  
gas is evident at the Pilot, the Gas Valve should be replaced as a complete assembly.  
Regulators: Vent caps must be kept clean and free from debris at all times.  
Pilot Solenoids: Using a test meter capable of measuring 0 - 50 mv connect the negative lead to the pilot bracket  
and the positive lead to the bottom connection on the hi limit. Light the pilot and allow enough time for the voltage  
to increase to a normal level. Turn the Gas Valve Knob to the OFF position and allow the pilot to go out. Listen for  
a small noise made when the Pilot Solenoid drops out. The millivoltage reading when this happens should be no  
more that 10 mv.

Hi Limits Thermostats:  
All Hi Limits are electric switches that OPEN at a pre determined temperature. Check for continuity across the  
terminations when the wires are disconnected.  
Thermocouples:  
Use a Multi Meter capable of measuring DC voltage below 1V. Attach the Negative lead to the Pilot Bracket and  
the Positive lead to the upper connection at the Hi Limit. Light the Pilot and measure the DC voltage. The voltage  
should be 25-35 mv. If the measured voltage is less than specified, the part should be changed.  
Pilots:  
Standard: Pilots must be kept clean and free from anything that might block the flow of gas.  
Electronic Ignition: As with Standard pilots, care must be taken to keep this area clean. The Electronic Ignition  
Pilot Assembly incorporates the Spark Tip which is encased in a ceramic insulator. Check for any cracks or signs  
of damage. Check the spark gap which should be between 3 - 6 mm. The High Voltage wire should also be free  
of damage. If the High Voltage Wire is suspected of being at fault it should be checked for continuity.  
Probes:  
Unplug the probe wires at a convenient location and check for resistance. Also check the temperature of the oil. If  
the resistance is NOT close to that shown on the chart below it should be changed.

Electronic Ignition Modules:  
The module receives a 24 vac signal from the Temperature control system and starts a cycle to light the pilot and  
prove the pilot flame. Check the module by following the steps below:  
{ Check between the THS Terminal and GROUND for 24 vac to verify that the module is receiving a signal.  
{ Listen for a spark sound. If NO spark sound can be heard, Turn the fryer OFF. Unplug the High Voltage Wire from  
the module and replace it with a new Electronic Ignition Pilot Assembly. Temporarily ground the Pilot assembly  
against a suitable Ground. Turn the machine ON and listen for a spark sound. If a sound can now be heard check  
the ground wire on the installed Pilot and repair if damaged. If a spark CAN be heard go to the next step.  
{ Check for 24 vac between the two wires at the Pilot solenoid on the Gas Valve. If voltage is found, turn the fryer  
OFF and check the Pilot Solenoid for a Resistance of 60 Ohms. If the resistance varies more than 10 Ohms from  
normal the Pilot Solenoid is defective and the Gas Valve must be replaced.  
{ If the Pilot comes on normally and the Main Burners do NOT, check for 24 vac at the Main Burner Solenoid of the  
Gas Valve. If voltage is found, turn the fryer OFF and check the Main Solenoid for a Resistance of 60 Ohms. If the  
resistance varies more than 10 Ohms from normal the Main Burner Solenoid is defective and the Gas Valve must  
be replaced.  
{ If a spark can be heard but it continues without the Pilot lighting check the Flame Sensor as described in the  
appropriate section.  
Flame Sensors:  
Run the fryer and check between the Flame Sensor wire and GROUND for 150 mv. If the millivoltage is NOT  
present the Electronic Ignition Module is at fault. Turn the fryer OFF, unplug the wire from the connection on the  
sensor. Connect a test meter capable of measuring Microamps in Series with the wire and the Flame Sensor.  
Run the fryer so that the Pilot lights. The meter reading should be between 0.15 - 0.35 ma. Remove the meter  
and replace the Flame Sensor wire. If the Microamperage is NOT present but the Millivoltage is, the Flame  
Sensor is at fault.  
Computers:  
{ If the computer does NOT have a lit display check for 24 vac between the Green/Yellow and Red wires on the fryer  
harness that plugs into the computer harness. If voltage is found, and the display is NOT lit the computer  
connections should be checked for integrity. If the connection is good the computer is faulty.  
{ If the display is lit but the Main Burners do NOT light, check for 24 vdc at the coil of the K6 relay. This is the Heat  
Demand Relay and is switched ON only when the computer calls for a heating cycle. If voltage is present when the  
computer is calls for a heat cycle the K6 relay may be at fault. If voltage is NOT present, check the computer

connections for integrity If the connection is good the Probe should be checked as described in the appropriate  
section. If the Probe is not at fault the computer may be suspect.  
{ If the display is lit but the Main Burners are still controlled by the Alternate Thermostat, check for 24 vdc at the K5  
relay. This relay is the Control Transfer Relay and is energized at all times when the computer is ON. When the  
computer senses an OPEN PROBE condition it will cease to energize the Control Transfer Relay and the Alternate  
Thermostat will control the Heat Demand.  
Digital Controls:  
Check for an input voltage of 24 vac between the Red and White/Black wires at the control. When the control is  
calling for a heating cycle check for a 24 vac output signal between Gray and the White/Black wires. If the control  
des NOT output a signal when calling for a heat cycle it should be replaced.  
Basket Lifts:  
Micro Switch: Check for continuity between all connections with the plunger in the in and out positions.  
Motors: Check for the incoming voltage between the two wire leading to the motor. If voltage is present but the  
motor does NOT turn the motor is defective. If the Basket Lift assembly comes UP and stops but drifts down, the  
brake assembly on the motor is defective and the motor must be changed. If the Basket Lift assembly moves up  
and down when operated but stops and starts at different positions check and adjust the Switch Actuation Plate  
located on the output shaft of the motor.  
Float Switches:  
It is important to keep Float Switches clean and free from debris. The Float Ball should only be installed with the  
writing in the UP position. To check the switch, electrically isolate the wiring and check for continuity.  
Interlock Switchs:  
These switches are mounted on the Drain Valve body and handle. When the handle is moved the Actuator  
(magnet) on moves away from the switch and causes it to OPEN, this can be verified by checking for continuity  
between the two wires that lead to the switch. The nominal gap between the Actuator and Switch should be  
between 3 - 6 mm.  
Relays:  
When the correct voltage is supplied to the coil the switch section of the relay will close. Relays may be checked  
by checking continuity between Switch terminals when the Relay IS and IS NOT energized.  
Hot Surface Ignitors (Also known as HSI - RPB14 Only):  
Disconnect the wiring harness leading to the part. Check for a resistance of 3 - 5 W while the Ignitor is at room  
temperature. Run the fryer for five minutes and recheck the resistance. The reading should now be 5 - 7 W.  
Hot Surface Ignition Modules (RPB14 Only):  
Check between the TH terminal and GROUND for 24 vac. For the first 4 seconds after the module receives  
voltage there will be a 24 vac output to the HSI. At this time the Check Fryer Light will light. This can be measured  
between terminals HSI1 and HSI2. After this initial period, the module outputs a 24 vac signal to the gas valve  
solenoid between VAL and GROUND. At the same time the HSI module sends a signal to the gas valve it begins  
to sense a 0.15 - 0.35 ma signal from the Hot surface Ignitor. If this signal is NOT found the module will shut  
down and send a 24 vac signal to the Check Fryer Light. This can be found by checking between the LAMP and  
GROUND terminals.  
Blower circuits (RPB14 Only):  
The same 24 vac signal that controls the HSI module also energizes a Blower Relay. This relay switches a 240  
vac signal to the Blower. Check for voltage at the Blower. The Relay can be checked in the same manner as  
described in the appropriate section.  
Burners (RPB14 Only) :  
In order to inspect the burners for defect they must be removed from the machine. There must be NO visible  
signs of damage, such as creases or holes. Remove the HSI before attempting to remove the burner, as they are  
easily damaged.

TROUBLE SHOOTING:  
Before diagnosing any machine for defective components check the following items:  
v Check all power cords and appropriate circuit breakers to ensure that electrical power is supplied to the machine.  
v Check all machine gas shut off valves to ensure that gas is supplied to the machine.  
v Check all machine fuses.  
v Check any appropriate electrical connections within the machine.  
v Check all appropriate switches and gas valve knobs to ensure that machine is operated correctly.
