CHAPTER 6: OPERATING INSTRUCTIONS
6.6 Testing Dual Hi-Limit Controls
Note: Perform this test before replacing old shortening. This high temperature test will greatly
reduce life of new shortening. Start test with the fryer turned ON and with the oil at normal
frying temperature. Stir the oil thoroughly to ensure even distribution and temperature and
place a pyrometer sensing probe in center of frypot about one-inch deep. When verifying oil
temperature, use a pyrometer indicating 0-6000F and a pryometer sensor probe. A high
temperature thermometer may be used instead of a pyrometer.
CAUTION
If the result listed for each step does not occur, turn off fryer at the main circuit breaker panel and do
not use the fryer. Call service agency.
To test the high limit thermostats, proceed as follows:
STEP 1: Press the hi-limit test switch to the 1st hi-limit switch and hold in that position until the
trouble light comes on. The trouble light should come in between 4100F + or - 30F, and
the heating elements must shut off. The HEAT light goes out and the TROUBLE light
comes on. Release the test switch.
STEP 2: Press the hi-limit test switch to the 2nd hi-limit position and hold in that position until the
2nd hi-limit light comes on. It should illuminate between 430°F and 460°F, and the heating
elements must shut off. Release the test switch. All fryers connected to the external shunt
power supply will be shut off completely and all control panel lights will be extinguished.
For fryers not connected to an external shunt power supply, the 2nd hi-limit light will come
on and the fryer will shut off.
STEP 3: Turn power switch to the OFF position.
STEP 3: Allow the cooking oil to cool to below normal frying temperature. When the power switch
is again turned ON, the heaters will turn on and the operating thermostat will resume
control of the temperature. If the red trouble light remains on instead, allow the oil
additional time to cool.
6-4
CHAPTER 7: DRAINING AND MANUAL FILTERING
WARNING
Use care when draining and filtering cooking oil/shortening to avoid serious burns.
7.1 Filtering
If you are using a filter other than a FRYMASTER built-in filter system, consult the filter unit
manufacturer’s operating instructions for the recommended procedures. Instructions for using the
FRYMASTER Footprint systems are included in Chapter 16 of this manual.
7.1.a Manual Filtering
The following procedure is recommended to drain and filter your cooking oil/shortening when a filter
machine is not available:
1. Turn the fryer controller power switch to the OFF position. Screw the drain extension pipe
(provided with the fryer) tightly into the drain valve. Make sure the curved end of the tube is
pointing down.
2. Position a metal container with sealable cover under the drain pipe. The metal container must be
able to withstand the hot cooking oil and other hot liquids and be of sufficient capacity to hold
the contents of the frypot. Frymaster recommends that a Frymaster filter cone holder and filter
cone be used when a filter machine is not available. If you are using the Frymaster filter cone
holder and cone, be sure the filter holder rests firmly on the metal container.
3. Open the drain valve slowly to avoid splattering. If splattering occurs, exercise extreme caution.
4. If the drain valve becomes clogged with food particles, use the Fryer’s Friend (poker-like tool).
Use this tool from inside of the frypot ONLY. Grip the tool on the handle as far as possible
from the hot shortening in the frypot. DO NOT HAMMER ON THE DRAIN VALVE, as this
will damage the drain valve ball.
WARNING
Never run water through built-in filtration system.
DANGER
Do not insert the tool into the front of the drain valve to unclog the valve. Hot oil will rush out,
creating an extreme burn hazard!
CAUTION
Allow the shortening to cool to 100°F (38°) or lower before transporting the container and removing
the drain pipe. Exposure to oil at temperatures above 140°F (60°C) can result in severe burns.
5. After draining the oil/shortening, clean all food particles and residual oil/shortening from the
frypot before refilling.
6. Close the drain valve and refill the frypot with clean (or filtered) oil/shortening.

1. Insert a good grade thermometer or pyrometer probe into the cooking oil/shortening near the fryer
temperature-sensing probe.
2. Turn thermostat knob to frying temperature.
3. Let elements cycle on and off automatically three times to allow the cooking oil temperature to be
uniform.
4. When the elements start for the fourth time, the pyrometer reading should be within 5°F (2°C) of
the thermostat knob setting. If it is not, calibrate as follows:
a. Loosen set screw in thermostat control knob until outer shell of knob will rotate on insert inside
knob.
b. Rotate outer shell of knob until index line on knob aligns with marking that corresponds to
thermometer or pyrometer reading.
c. Hold knob and tighten set screw.

f. If calibration cannot be obtained for any reason, call a Factory Authorized Service Center.
5. Remove thermometer or pyrometer probe.
8.2 Hi-Limit tests
Hi-limit 1 checks the ability of the fryer’s controller to shut down
the fryer.
The test is conducted with the oil at or near operating temperature.
Hold the Hi-limit rocker switch in the 1st position.
The oil will heat to 4100F +- 30F degrees before the controller stops
calling for heat. The trouble light will illuminate just at the heat
light goes out.
Reset the fryer by turning the unit off and back on at the control
panel.
Hi-Limit 2 checks the ability of the fryer’s mechanical hi-limit
probe to shut down the fryer. To run the test, hold the rocker
switch in the 2nd position. With the rocker depressed, the oil will
heat to 430-4500F degrees before the mechanical hi-limit probe
opens, which shuts off power to the fryer.

CHAPTER 12: OIL FILTRATION (Surface Ship Only)
DANGER
Never attempt to remove a filter pan containing hot cooking oil/shortening. Hot oil/shortening will flow
through the outlet in the bottom of the pan and cause severe burns to feet and legs.
CAUTION
Never operate the filter unit unless the cooking oil/shortening in the fryers has been brought up to cooking
temperature.
NOTE: Exercise care when using the Fryer's Friend to prevent damage to the frypot and the drain valve.
Do not drain more than one frypot at a time. To do so will cause overfilling of the filter pan.
DANGER
Except when using the rear flush option, do not operate without power shower. Hot cooking oil/
shortening can splash and cause injury.
NOTE: Filter motor is equipped with a manual reset switch in case the filter motor overheats or an
electrical fault occurs.
CAUTION
Turn off power to the filter system and allow pump motor to cool 20-30 minutes before attempting to
reset switch on the pump motor
WARNING!
The crumb tray must be emptied into a fireproof container at the end of each day. Some food
particles can spontaneously combust if left in certain shortening.

CHAPTER 13
CARE AND CLEANING OF THE FILTER SYSTEM
DANGER:
WARNING:
NEVER use the filter pan to dispose or
transport old cooking oil/shortening to the
disposal area.
Never operate the filter system without
cooking oil in the system.
Always allow cooking oil to cool below 100°F (38°C) before transporting to the disposal area. A
Shortening Disposal Unit (SDU), available from your local distributor, is available and highly
recommended for safety.
1. Do not drain water into the filter pan. Water will damage the filter pump. Perform the following
to drain the frypot:
A. Footprint III
1) Pull the filter carriage forward.
2) Remove the empty filter pan assembly.
3) Push the filter carriage back into the fryer.
4) Place suitable container under the drain.
5) Open the drain valve.
A. Footprint III - the o-ring is on the bottom of
the filter pan.
3. Immediately after use, drain the power shower completely. If you suspect blockage, unscrew the
plugs at each corner of the power shower frame. Use a long narrow bottle brush with hot water
and detergent to clean the inside of the power shower. Rinse, dry thoroughly, and reinsert plugs
before using.
CHAPTER 13
CARE AND CLEANING OF THE FILTER SYSTEM
13.1 Filtration Problems
One of the most common errors is placing the filter
paper on the bottom of the filter pan rather than on
top of the filter screen.
Whenever the complaint is “the pump is running,
but no oil is returning,” check the installation of the
filter paper, and ensure that the correct size paper is
being used. While you are checking the filter
paper, verify that the o-ring on the bottom of the
filter pan (and on the suction tube if applicable) is
present and in good condition. A missing or worn
o-ring allows the pump to suck air and decrease its
efficiency.
The filter screen must go in the bottom of the pan
first. The filter paper goes on top of the screen.
For Filter Magic Systems, if the pump runs, but does not return oil, the most likely causes are that the
filter carriage is not properly positioned all the way to the rear of the fryer or the suction tube o-rings
are missing or worn.
If the pump motor overheats, the thermal overload will trip and the motor will not start until it is
reset. If the pump motor does not start, press the red reset switch located on the end of the motor.
If the pump then starts, something caused the motor to overheat. If the motor runs for a prolonged
period, it may overheat. Allow the motor to cool down for at least 30 minutes and press the reset
button.
The pump may also overheat for one of the fo llowing reasons:
• Shortening solidified in the pan or filter lines.
• The operator attempted to filter oil or shortening that was not heated. Cold oil and shortening are
thicker and cause the pump motor to work harder and overheat.
If the pump will not return oil and you hear a humming sound just before the overload trips, the pump
is blocked. Paper which is incorrectly sized or installed will allow food particles and sediment to
pass through the filter pan and into the pump. When sediment enters the pump, the gears may bind
causing the motor to overload, tripping the reset circuit breaker. Solidified shortening in the pump
may also prevent it from turning, with the same result.
CHAPTER 13
CARE AND CLEANING OF THE FILTER SYSTEM
FREEING A SIEZED PUMP
Freeing a Seized Pump
Sediment Particle
Up for reverse
Down for forward
A pump seized by debris or hard shortening can usually be freed by manually moving the gears with
a screwdriver or other instrument.
1. Disconnect power to the filter system.
2. Remove the input plumbing from the pump.
3. Use a screwdriver to manually turn the gears.
• Turning the pump gears backward will release a hard particle.
• Turning the pump gears forward will push softer objects and solid shortening through the pump
and allow free movement of the gears.
Incorrectly sized or installed paper will also allow food particles and sediment to pass through and
clog the suction tube on the bottom of the filter carriage. Particles large enough to block the suction
tube may indicate that the crumb tray is not being used.
Pan blockage can also occur if shortening is left in the pan and allowed to solidify. The heater strip
on the suction tube is designed to prevent solidification of residual shortening left in the tube. It will
not melt or prevent solidification of shortening in the pan.
A blockage can be removed by forcing the item out with a stiff wire or drain snake. Compressed air
or other pressurized gases should not be used to force out the blockage.
Possible problems with the Power Shower include clogged openings, solidified shortening or debris
in the tubes, missing clean-out plugs, and missing or worn O-rings. Cleaning the unit and replacing
missing plugs and missing or worn O-rings will correct these problems.
The electronics of the filter system are simple and straightforward. Micro-switches, attached to
handles for each vat and wired in parallel, provide the 24 VAC required to energize the pump relay
coil when the oil return handles are moved to the ON position. The energized pump relay supplies
the power to the pump motor.
The suction tube heater and flexible hose heater are wired directly into the 24 VAC source. They
remain energized as long as the unit is plugged into an outlet.
