Equipment Description
Fryers in the 47 Series are of an open-pot design with no tubes and have a hand-sized opening into
the deep cold zone, which simplifies cleaning the frypot. Units consisting of a battery of two or
more fryers may also be equipped with a FootPrint III built-in filtration system, which prolongs the
useful life of oil or shortening.
1-2
Fryers equipped with FootPrint III built-in filtration systems are shipped completely assembled.
Fryers without the FootPrint III require installation of legs or optional casters at point of use. All
fryers are shipped with a package of standard accessories. Each fryer is adjusted, tested, and
inspected at the factory before crating for shipment.
Frypots are constructed of welded, heavy-gauge stainless steel. Heating is supplied by a burner
assembly having multiple gas jets that are focused on ceramic targets located around the lower side
of the frypot. The burner assembly can be configured for natural gas, propane, or manufactured gas
as required by the customer. A drain is tapped into the center of the frypot, with a front-controlled
manual ball valve.
Each fryer is equipped with a thermostat probe for precise temperature control. The probe is located
on the centerline of the frypot for rapid response to changes in loads and to provide the most
accurate temperature measurement.
47 Series fryers may be equipped with an optional melt cycle feature which pulses the burner on and
off at a controlled rate. The melt cycle feature is designed to prevent scorching and uneven heating
of the frypot for customers who use solid shortening.
The controls on your fryer vary depending on the model and configuration purchased. Control
options include one or more thermostat controllers, digital controllers, basket lift timers, or
Computer Magic III computers.

CHAPTER 2: INSTALLATION INSTRUCTIONS
2.1
General Installation Requirements
Qualified, licensed, and/or authorized installation or service personnel, as defined in Section
1.7 of this manual, should perform all installation and service on Frymaster equipment.
Conversion of this appliance from one type of gas to another should only be performed by
qualified, licensed, and/or authorized installation or service personnel as defined in Section 1.7
of this manual.
Failure to use qualified, licensed, and/or authorized installation or service personnel (as
defined in Section 1.7 of this manual) to install, convert to another gas type or otherwise
service this equipment will void the Frymaster warranty and may result in damage to the
equipment or injury to personnel.
Where conflicts exist between instructions and information in this manual and local or
national codes or regulations, installation and operation shall comply with the codes or
regulations in force in the country in which the equipment is installed.
DANGER
Building codes prohibit a fryer with its open tank of hot oil/shortening being installed
beside an open flame of any type, including those of broilers and ranges.
DANGER
Frymaster appliances equipped with legs are for stationary installations. Appliances
fitted with legs must be lifted during movement to avoid damage to the appliance
and bodily injury. For movable installations, optional equipment casters must be
used. Questions? Call 1-800-551-8633.
DANGER
Do not attach an apron drainboard to a single fryer. The fryer may become unstable,
tip over, and cause injury. The appliance area must be kept free and clear of
combustible material at all times.
Upon arrival, inspect the cooker carefully for visible or concealed damage. (See Shipping Damage
Claim Procedure in Chapter 1.)
CLEARANCE AND VENTILATION
The fryer(s) must be installed with a 6” (150 mm) clearance at both sides and back when installed
adjacent to combustible construction; no clearance is required when installed adjacent to
noncombustible construction. A minimum of 24” (600 mm) clearance should be provided at the
front of the fryer.
2-1
One of the most important considerations of efficient fryer operation is ventilation. Make sure the
fryer is installed so that products of combustion are removed efficiently, and that the kitchen
ventilation system does not produce drafts that interfere with proper burner operation.
The fryer flue opening must not be placed close to the intake of the exhaust fan, and the fryer must
never have its flue extended in a “chimney” fashion. An extended flue will change the combustion
characteristics of the fryer, causing longer recovery time. It also frequently causes delayed ignition.
To provide the airflow necessary for good combustion and burner operation, the areas surrounding
the fryer front, sides, and rear must be kept clear and unobstructed.
Fryers must be installed in an area with an adequate air supply and adequate ventilation. Adequate
distances must be maintained from the flue outlet of the fryer to the lower edge of the ventilation
filter bank. Filters should be installed at an angle of 45º. Place a drip tray beneath the lowest edge
of the filter. For U.S. installation, NFPA standard No. 96 states, “A minimum distance of 18 in.
(450 mm) should be maintained between the flue outlet and the lower edge of the grease filter.”
Frymaster recommends that the minimum distance be 24 in. (600 mm) from the flue outlet to the
bottom edge of the filter.
Information on construction and installation of ventilating hoods can be found in the NFPA standard
cited above. A copy of the standard may be obtained from the National Fire Protection Association,
Battery March Park, Quincy, MA 02269.
DANGER
No structural material on the fryer should be altered or removed to accommodate
placement of the fryer under a hood. Questions? Call the Frymaster/Dean Service
Hotline at 1-800-551-8633.
DANGER
This appliance must be installed with sufficient ventilation to prevent the occurrence
of unacceptable concentrations of substances harmful to the health of personnel in
the room in which it is installed.
NATIONAL CODE REQUIREMENTS
The type of gas for which the fryer is equipped is stamped on the data plate attached to the inside of
the fryer door. Connect a fryer stamped “NAT” only to natural gas, those stamped “PRO” only to
propane gas, and those stamped “MFG” only to manufactured gas.
Installation shall be made with a gas connector that complies with national and local codes, and,
where applicable, CE codes. Quick-disconnect devices, if used, shall likewise comply with national,
local, and, if applicable, CE codes.
ELECTRICAL GROUNDING REQUIREMENTS
All electrically operated appliances must be grounded in accordance with all applicable national and
local codes, and, where applicable, CE codes. A wiring diagram is located on the inside of the fryer
door. Refer to the rating plate on the inside of the fryer door for proper voltages.
2-2
DANGER
This appliance is equipped with a three-prong (grounding) plug for your protection
against electrical shock, and must be plugged directly into a properly grounded
three-prong receptacle. Do not cut, remove, or otherwise bypass the grounding
prong on this plug!
DANGER
This appliance requires electrical power for operation. Place the gas control valve in
the OFF position in case of a prolonged power outage. Do not attempt to operate
this appliance during a power outage.
FCC COMPLIANCE
The user is cautioned that any changes or modifications to Frymaster computers not expressly
approved by the party responsible for compliance could void the user’s authority to operate the
equipment.
Frymaster computers have been tested and found to comply with the limits for a Class A digital
device, pursuant to Part 15 of the FCC rules. While these devices are verified as Class A devices,
they have been shown to meet the Class B limits. These limits are designed to provide reasonable
protection against harmful interference when the equipment is operated in a commercial
environment. This equipment generates, uses, and can radiate radio frequency energy and, if not
installed and used in accordance with the instruction manual, may cause harmful interference to
radio communications. Operation of the equipment in a residential area is likely to cause harmful
interference in which case the user will be required to correct the interference at his own expense.
If necessary, the user should consult the dealer or an experienced radio and television technician for
additional suggestions.
The user may find the booklet “How to Identify and Resolve Radio-TV Interference Problems”
helpful. It is prepared by the Federal Communications Commission and is available from the U.S.
Government Printing Office, Washington, DC 20402, Stock No. 004-000-00345-4.
2.2
Caster/Leg Installation
Depending upon the specific configuration ordered your fryer may have been shipped without
installed casters or legs. If casters or legs are installed, you may skip this section and proceed to
section 2.3, Pre-Connection Preparations.
If your fryer requires the installation of casters/legs, install them in accordance with the
instructions included in your accessory package.
2-3
2.3
Pre-Connection Preparations
DANGER
Do not connect this appliance to the gas supply before completing each step in this
section.
After the fryer has been positioned under the exhaust hood, ensure the following has been
accomplished:
1. Adequate means must be provided to limit the movement of fryers without depending upon the
gas line connections. If a flexible gas hose is used, a restraining cable must be connected at all
times when the fryer is in use. The restraining cable and installation instructions are packed with
the flexible hose in the accessories box that was shipped with your unit.
2. Single unit fryers must be stabilized by installing restraining chains on appliances equipped with
casters or anchor straps on appliances equipped with legs. Follow the instruction shipped with
the casters/legs to properly install the chains or straps.
DANGER
Do not attach an apron drain board to a single unit. The appliance may become
unstable, tip over, and cause injury. The appliance area must be free and clear of
combustible material at all times.
3. Level fryers equipped with legs by screwing out the legs approximately 1 inch then adjusting
them so that the fryer is level and at the proper height in the exhaust hood. Frymaster
recommends that the minimum distance from the flue outlet to the bottom edge of the filter be 24
in. (600 mm) when the appliance consumes more than 120,000 BTU per hour.
For fryers equipped with casters, there are no built-in leveling devices. The floor where the fryer
is to be installed must be level.
4. Test the fryer electrical system:
a. Plug the fryer electrical cord(s) into a grounded electrical receptacle.
b. Place the power switch in the "ON" position.
•
For fryers equipped with thermostat controls, verify that the power and heat lights are lit.
•

2. Ensure the fryer ON/OFF Switch is in the "OFF" position, then light the pilot. (Refer to Chapter
3 for detailed lighting instructions.)
3. Insert a good grade thermometer or pyrometer into the frypot so that it touches the thermostat
guard.
4. Disconnect the solid extension shaft from the end of the flexible shaft using an appropriately
sized Allen wrench.
5. Remove the flexible shaft from the thermostat shaft screw.
6. Place the fryer ON/OFF switch in the "ON" position.
NOTE: If the burner does not light at this time, it does not mean the thermostat is defective.
Recheck the wiring, and then slowly turn the thermostat adjusting screw counterclockwise
until the burner lights. (Turning the adjusting screw counterclockwise causes the burner to
light and clockwise causes it to shut off.)
7. When the cooking oil/shortening temperature reaches 325°F (162°C), turn the thermostat
adjusting screw slowly clockwise until the burner shuts off.
8. Allow the fryer to sit for a few minutes, then slowly turn the thermostat adjusting screw
counterclockwise until the burner lights.
9. Repeat steps 7 and 8 at least three times to ensure an accurate setting is obtained. The
Thermostat Control is considered to be properly calibrated if the burner lights as the cooking
oil/shortening cools to 325°F (162°C), and not when the burner shuts off as the temperature rises.
10. Once the calibration point of 325°F (162°C) is determined, allow the burner to cycle on and off
at least 3 times to be sure it will light at the calibrated temperature.
11. After the calibration is complete, place the fryer power switch in the "OFF" position and
disconnect the fryer from the electrical supply.
12. Carefully install the thermostat flexible extension on the thermostat shaft, ensuring that the
setscrews are tight.
CAUTION
The adjusting screw must not be moved while installing the flexible extension shaft.
13. Install the solid metal extension shaft on the end of the flexible shaft with the stop pin at the 12
o’clock position. Ensure the stop pin and setscrews are tight to prevent slippage.
2-8
14. Reinstall and secure the fryer control panel. Loosen the temperature dial plate screws and rotate
the dial until the 325°F (162°C) index mark is at the 12 o’clock position, then retighten the
screws.
15. Reinstall the thermostat knob with its pointer aligned with the 325°F (162°C) index mark on the
temperature dial plate. Tighten the thermostat knob set screws to prevent slippage.

47 SERIES GAS FRYERS
CHAPTER 3: OPERATING INSTRUCTIONS
3.1
Start-Up Procedure
DANGER
Never operate this appliance with an empty frypot. The frypot must be filled with
water or cooking oil/shortening before lighting the burners. Failure to do so will
damage the frypot and may cause a fire.
WARNING
The on-site supervisor is responsible for ensuring that operators are made aware of
the inherent hazards of operating a hot oil filtering system, particularly the aspects
of oil filtration, draining and cleaning procedures.
CAUTION
The cooking oil/shortening capacity of the 47 Series fryer is 50 lbs (25 liters) at 70°F
(21°C) for a full-pot and 25 lbs (12.5 liters) at 70°F (21°C) for each half of a split-pot.
Before lighting the fryer, make sure the fryer is OFF and the frypot drain valve(s)
is/are closed. Remove the basket support rack(s), if installed, and fill the frypot to
the bottom OIL LEVEL line. If solid shortening is being used, make sure it is packed
down into the bottom of the frypot.
NOTE: For units configured as pilot ignition (millivolt) systems, the pilot must be
manually lit before the fryer can be placed into operation. On fryers configured with
electronic ignition, the pilot is automatically lit when the unit is turned on.
ACCESSING THE PILOT
In full-vat units, the pilot is mounted on the left side of the burner manifold and is accessed through
an opening in the front frypot insulation. In dual-vat units, there is a pilot on both the left and the
right halves of the burner manifold. In either case, swing the round cover over the opening out of
the way and insert a long match or taper through the hole to light the pilot.
LIGHTING THE PILOT ON NON-EUROPEAN (NON-CE) FRYERS
1. Ensure power to the unit is OFF, then turn the gas valve knob to the OFF position. Wait at least
5 minutes, then rotate the gas valve knob to the PILOT position (see Figure 1).

2. Push the knob in and light the pilot. (If the fryer is equipped with a piezo ignitor, repeatedly
press the piezo ignitor button while depressing the gas valve knob until the pilot lights.)
Continue to hold the knob in for about 60 seconds after the flame appears on the pilot. Release
the knob. The pilot should remain lit.
CAUTION
If the pilot fails to remain lit, turn the gas valve knob to the OFF position and wait at
least five minutes before attempting to re-light.
3. With the pilot lit, push down and slowly turn the knob to the ON position (see Figure 2 on Page
3-1).
LIGHTING THE PILOT ON FRYERS BUILT FOR THE EUROPEAN COMMUNITY (CE)
1. Ensure power to the unit is OFF, then press the OFF (red) button on the gas valve (see photo
below). Wait at least 5 minutes.
PILOT Button
OFF Button
2. Place a flame near the pilot assembly, push and hold the PILOT (white) button in, light the pilot,
and continue to depress the button for at least 60 seconds after the pilot lights. (If the fryer is
equipped with a piezo ignitor, press the ignitor button repeatedly while holding in the PILOT
button until the pilot lights.) Failure to hold the button in long enough will cause the pilot to go
out when the button is released. If the pilot goes out when the button is released, wait at least 5
minutes then repeat this step.
NOTES ABOUT FRYERS WITH ELECTRONIC IGNITION SYSTEMS
WARNING
Never use a match or taper to light the pilot on this ignition system.
When the computer/controller power switch is placed in the ON position, the ignition module will
turn the pilot gas supply on and provide an ignition spark. The spark will light the pilot. A flame
sensor verifies the presence of the pilot flame. Unless the pilot flame is sensed, the ignition module
will not allow the gas valve to supply gas to the burners. The computer/controller controls the firing
of the burners after pilot ignition takes place.
If the pilot flame fails, the ignition module will shut down and “lock out” the system. To restart the
system, turn the computer/controller OFF, wait approximately 5 minutes for the system to recycle
itself, then turn the computer/controller ON again.
3-2
WARNING
In the event of prolonged power failure, the ignition module will shut down and “lock
out” the system. Turn the computer/controller OFF and then back ON after power
has been re-established.
PLACING THE FRYER INTO OPERATION
CAUTION
If this is the first time the fryer is being used after installation, refer to Section 3.2,
Boil-Out Procedure.
For units equipped with Thermostat Controls:
Place the Melt Cycle switch (if so equipped) to the ON position and set the thermostat knob to
the desired cooking temperature. The U-shaped burner should ignite and burn with a strong,
blue flame.
CAUTION
Thermostat-controlled fryers equipped with Melt Cycle switches will stay in the Melt
Cycle mode until the Melt Cycle Switch is placed in the OFF position.
For units equipped with other than Thermostat Controls:
Place the computer/controller ON/OFF switch in the ON position and set the controller to – or
program the controller for – the desired cooking temperature, referred to as the setpoint. The
U-shaped burner should ignite and burn with a strong, blue flame. The unit automatically enters
the Melt Cycle mode if the frypot temperature is below 180°F (82°C). (NOTE: During the melt
cycle, the burner will repeatedly fire for a few seconds, then go out for a longer period.) When
the frypot temperature reaches 180°F (82°C), the unit will automatically switch to the Heating
mode. The burner will remain lit until the frypot temperature reaches the programmed cooking
temperature (setpoint).
3.2
Boiling-Out the Frypot
To ensure that the frypot is free of any contamination resulting from its manufacture, shipping, and
handling during installation, the frypot must be boiled out before first use. Frymaster recommends
boiling out the frypot each time the oil or shortening is changed.
DANGER
Never leave the fryer unattended during the boil-out process. If the boil-out solution
boils over, turn the fryer off immediately and let the solution cool for a few minutes
before resuming the process. To lessen the chance of boil over, turn the fryer’s gas
valve knob to the PILOT position occasionally.
1. Before lighting the burner, close the fryer drain valve(s) and fill the frypot to the bottom OILLEVEL line with a mixture of cold water and dishwashing detergent.
3-3
2. For units equipped with a Thermostat or Solid State (Analog) Controller, set the thermostat to

gallons (8 liters) of cold water and stir. Drain the solution into a suitable container and clean the
frypot thoroughly.
WARNING
Do not drain boil-out solution into a shortening disposal unit, a built-in filtration unit,
or a portable filter unit. These units are not intended for this purpose, and will be
damaged by the solution.
6. Rinse the frypot at least twice by filling the frypot with clean water and draining. Dry the frypot
thoroughly with a clean, dry towel.
DANGER
Remove all drops of water from the frypot before filling with cooking oil or
shortening. Failure to do so will cause spattering of hot liquid when the oil or
shortening is heated to cooking temperature and may cause injury to nearby
personnel.
3.3
Shutting the Fryer Down
For short-term shut down during the workday, place the fryer power switch in the "OFF" position
and put the frypot covers in place (if the fryer is so equipped).
When shutting the fryers down at closing time, place the fryer power switch in the "OFF" position,
place the gas valve in the "OFF" position, and put the frypot covers in place (if the fryer is so
equipped).

47 SERIES GAS FRYERS
CHAPTER 4: FILTRATION INSTRUCTIONS
4.1
Draining and Manual Filtering
WARNING
The on-site supervisor is responsible for ensuring that operators are made aware of
the inherent hazards of operating a hot oil filtering system, particularly the aspects
of oil filtration, draining and cleaning procedures.
DANGER
Draining and filtering of cooking oil or shortening must be accomplished with care to
avoid the possibility of a serious burn caused by careless handling. The oil to be
filtered is at or near 350°F (177°C). Ensure all hoses are connected properly and
drain handles are in their proper position before operating any switches or valves.
Wear all appropriate safety equipment when draining and filtering cooking oil or
shortening.
DANGER
NEVER attempt to drain cooking oil or shortening from the fryer with the burner lit!
Doing so will result in a flash fire if the oil or shortening splashes onto the burner.
Also, applying burner heat to an empty frypot will severely damage the frypot and
void the Frymaster warranty.
DANGER
Allow oil/shortening to cool to 100ºF (38ºC) or lower before draining to an
appropriate container for disposal.
If your fryer is not equipped with the built-in FootPrint III Filtration System, the cooking oil or
shortening must be drained into another suitable container. For safe, convenient draining and
disposal of used cooking oil or shortening, Frymaster recommends the use of the Frymaster
Shortening Disposal Unit (SDU). The SDU is available through your local distributor.
DANGER
When draining oil/shortening into a disposal unit or portable filter unit, do not fill
above the maximum fill line located on the container.
1. Turn the fryer power switch to the OFF position. Screw the drainpipe (provided with your fryer)
into the drain valve. Make sure the drainpipe is firmly screwed into the drain valve and that the
opening is pointing down.
2. Position a metal container with a sealable cover under the drainpipe. The metal container must
be able to withstand the heat of the cooking oil/shortening and hold hot liquids. If you intend to
reuse the oil or shortening, Frymaster recommends that a Frymaster filter cone holder and filter
cone be used when a filter machine is not available. If you are using a Frymaster filter cone
holder, be sure that the cone holder rests securely on the metal container.
4-1
3. Open the drain valve slowly to avoid splattering. If the drain valve becomes clogged with food
particles, use the steel clean-out rod to clear the blockage.
DANGER
NEVER attempt to clear a clogged drain valve from the front of the valve! Hot oil or
shortening will rush out creating the potential for severe burns.
DO NOT hammer on the drain valve with the cleanout rod or other objects. Damage
to the ball inside will result in leaks and will void the Frymaster warranty.
4. After draining the oil/shortening, clean all food particles and residual oil/shortening from the
frypot. BE CAREFUL, this material may still cause severe burns if it comes in contact with bare
skin.
5. Close the drain valve securely and fill the frypot with clean, filtered or fresh cooking oil or solid
shortening to the bottom OIL-LEVEL line.
DANGER
When using solid shortening, pack it down into the bottom of the frypot. DO NOT
operate the fryer with a block of shortening sitting in the upper portion of the frypot.
This will cause damage to the frypot and may cause a flash fire.
4.2
Operation of the FootPrint III Built-In Filtration System
The FootPrint III (FP III) filtration system allows cooking oil or shortening in one frypot to be safely
and efficiently filtered while the other frypots in a battery remain in operation. Operation of the
FootPrint III system is illustrated in the steps below. Most reported problems with these systems are
caused by improper operation. Careful attention to the instructions that follow will ensure that your
system operates as intended.
4.2.1 Preparing the Filter Unit for Use and/or Changing the Filter Paper
1. Pull the filter unit from the cabinet, open the cover, and remove the crumb tray.
4-2
2. Remove the paper hold-down ring (and if changing the filter paper, remove and discard the used
filter paper). Remove the filter screen and clean the crumb tray, hold-down ring, filter screen,
and pan with a solution of hot water and dishwashing detergent, ensuring that all breading and
food particles are removed from the pan. Ensure the pan is dried completely. Allow the screen
to dry completely before reinstalling.
3. After verifying that the metal filter screen is in the bottom of the pan, lay a sheet of filter paper
over the top of the pan, overlapping on all sides.
4. Position the hold-down ring over the filter paper and lower the ring into the pan, allowing the
paper to fold up around the ring as it is pushed to the bottom of the pan, then sprinkle filter
powder over the filter paper. (For powder quantity, see the filter powder manufacturer’s
instructions.)
5. Replace the crumb tray in the filter pan, close
the cover, and push the filter pan back into
the fryer, positioning it all the way to the
back of the cabinet.
4-3
4.2.3 Operating the Filter Unit
CAUTION
Never operate the filter unit unless the cooking oil/shortening is at operating
temperature.
1. To filter the cooking oil, turn the fryer power
OFF, then open the drain valve on the fryer
you have selected to filter.
2. Use the steel clean-out rod to clear the drain from inside the frypot as necessary.
DANGER
Do not drain more than one frypot at a time into the built-in filtration unit to avoid
overflow and spillage of hot oil/shortening.
DANGER
NEVER attempt to clear a clogged drain valve from the front of the valve! Hot oil or
shortening will rush out creating the potential for severe burns. DO NOT hammer on
the drain valve with the cleanout rod or other objects. Damage to the ball inside will
result in leaks and will void the Frymaster warranty.
3. Snap the Power Shower into the frypot.
DANGER
DO NOT operate the filter without the Power Shower in place. Hot oil will spray out
of the fryer and cause injury.
4-4
4. After all the cooking oil/shortening has
drained from the frypot, rotate the oil return
handle to RETURN to start the pump and
begin the filtering process. There may be a
slight delay before the pump activates.
5. The cooking oil/shortening is pulled through
the filter and pumped up to and through the
Power Shower, finally returning to the filter
pan through the open frypot-drain.
Polishing is the process of circulating the
cooking oil/shortening through the filter for
several minutes to ensure that fine particles
are removed.
Polish the cooking oil/shortening by allowing
it to circulate through the filtration system
and frypot for about 5 minutes.
6. After the oil is filtered, close the drain valve
and allow the fryer to refill.
NOTE: Ensure the drain valve is fully
closed. If the drain valve is not fully closed,
the controller will display an error message
or a trouble light when the fryer is turned on
again after the filtering process and the
burners will not light.
4-5
7. Let the filter run 10 to 12 seconds after
oil/shortening stops coming out of the Power
Shower to clear the lines and prevent
shortening from hardening in them. Rotate
the oil return handle to the OFF position to
stop the pump. Remove the Power Shower
and allow it to drain. Turn the fryer on and
allow the cooking oil/shortening to reach
setpoint.
DANGER
The crumb tray in fryers equipped with a filter system must be emptied into a
fireproof container at the end of frying operations each day. Some food particles
can spontaneously combust if left soaking in certain shortening material.
WARNING
The filter pump is equipped with a manual reset switch in case the filter motor
overheats or an electrical fault occurs. If this switch trips, turn off power to the filter
system and allow the pump motor to cool 20 minutes before attempting to reset the
switch.
The switch is accessed by pulling the filter assembly out of the fryer cabinet so that
the motor can be reached. The switch is the red button on the face of the motor (see
photo below).

CHAPTER 5: PREVENTIVE MAINTENANCE
5.1 Fryer Preventive Maintenance Checks and Services
DAILY CHECKS AND SERVICES
Inspect Fryer and Accessories for Damage
Look for loose or frayed wires and cords, leaks, foreign material in frypot or inside cabinet, and any
other indications that the fryer and accessories are not ready and safe for operation.
Clean Fryer Cabinet Inside and Out
DANGER
Never attempt to clean fryer during the cooking process or when the frypot is filled
with hot oil/shortening. If water comes in contact with oil/shortening heated to
cooking temperature, it can cause the oil/shortening to splatter and severely burn
nearby personnel.
WARNING
Use a commercial-grade cleaner formulated to effectively clean and sanitize
food-contact surfaces. Read the directions for use and precautionary statements
before use. Particular attention must be paid to the concentration of cleaner and the
length of time the cleaner remains on the food-contact surfaces.
Clean inside the fryer cabinet with dry, clean cloth. Wipe all accessible metal surfaces and
components to remove accumulations of oil or shortening and dust.
Clean the outside of the fryer cabinet with a clean, damp cloth soaked with dishwashing detergent,
removing oil/shortening, dust, and lint from the fryer cabinet.
Filter Cooking Oil/Shortening
The cooking oil/shortening used in your fryer should be filtered at least once every day (more often
if the fryer is in constant use). Refer to Chapter 4, Filtration Instructions, for details.
WEEKLY CHECKS AND SERVICES
Check Recovery Time
"Recovery time" is the amount of time it takes the fryer to raise the oil temperature from 250°F to
300°F (121°C to 149°C). It is a measure of the fryer’s efficiency, and it should be no more than 2
minutes and 30 seconds. If the recovery time is greater than 2 minutes and 30 seconds, call your
Factory Authorized Service Center (FASC) or the Frymaster Service Hotline.
The recovery time on models having CM III computers is automatically measured by the computer.
For fryers with any other type controller, the recovery time must be manually measured.
5-1
To view the recovery time on fryers equipped with CM III computers, press the Program Mode
Switch .
will appear in the left display. Enter
(1 6 5 2) using the number
keys. The latest recovery time will appear in both displays for 5 seconds.
To check the recovery time on fryers equipped with other than CM III computers, a stopwatch (or a
watch with a second hand) and a good grade thermometer or pyrometer is required.
Turn the fryer on and set the controller to cooking temperature. Place the thermometer or pyrometer
in the frypot. When the frypot reaches 250°F (121°C), start the stopwatch or record the time. When
the temperature reaches 300°F (149°C), stop the stopwatch or record the time.
QUARTERLY CHECKS AND SERVICES
Drain and Clean Frypot
During normal usage of your fryer, a deposit of carbonized cooking oil or shortening will gradually
form on the inside of the frypot. In order to maintain your fryer’s efficiency, this deposit must be
periodically removed by boiling out the frypot. Refer to Section 4.1 of Chapter 4 for instructions on
draining the frypot and to Section 3.2 of Chapter 3 for instructions on boiling out the frypot.
Clean Detachable Parts and Accessories
As with the frypot, a deposit of carbonized oil/shortening will accumulate on detachable parts and
accessories such as baskets, sediment trays, or fish plates
Wipe all detachable parts and accessories with a clean cloth dampened with a detergent solution.
Rinse and thoroughly dry each part.
Check Calibration of Thermostat or Analog Controller Temperature Control Knob
(NOTE: This check applies only to units equipped with Thermostat or Solid State (Analog)
Controllers.)
1. Set the temperature control knob to frying temperature.
2. Let the burner cycle on and off automatically three times to allow the cooking oil/shortening
temperature to become uniform. If necessary, stir to get all shortening in the bottom of the
frypot melted.
3. Insert a good-grade thermometer or pyrometer probe into the oil/shortening, with the end
touching the fryer temperature probe.
4. When the burner starts for the fourth time, the thermometer/pyrometer reading should be within
± 5ºF (2ºC) of the thermostat knob setting. If it is not, calibrate as follows:
a. Loosen setscrew in thermostat control knob until the knob will rotate freely on its shaft.
b. Rotate the knob until the index line on the knob is aligned with the marking that corresponds
to the thermometer or pyrometer reading.
5-2
c. Hold the knob and carefully tighten the setscrew.
d. Recheck the thermometer/pyrometer reading against the thermostat knob setting the next
time the burner lights.
e. Repeat steps 4.a through 4.d until the thermometer/pyrometer reading and knob setting agree
within ± 5ºF (2ºC).
5. Remove the thermometer or pyrometer.
If calibration cannot be obtained, call a Factory Authorized Service Center for assistance.
Check Thermostat Controller Thermostat Calibration
(NOTE: This check applies only to units equipped with Thermostat Controllers.)
1. Set the temperature control knob to 325°F (162°C) and insert a good grade thermometer or
pyrometer into the frypot so that it touches the temperature probe guard.
2. When the burner cycles off, set the temperature control knob to 340°F (170°C). As the reading
on the thermometer or pyrometer nears the control knob setting, but before the burner cycles off,
reset the knob to 325°F (162°C). Just as the reading on the thermometer or pyrometer drops
below 325°F (162°C), the burner should cycle on. If it does not, calibration is required. Call
your Factory Authorized Service Center (FASC) to arrange this service.
Check Computer Magic III Set Point Accuracy
(NOTE: This check applies only to units equipped with Computer Magic III Controllers.)
Insert a good-grade thermometer or pyrometer probe into the oil/shortening, with the end touching
the fryer temperature-sensing probe.
1. When the computer display shows a series of four dashes "
" with no dot between the
first and second dashes (indicating that the oil/shortening temperature is plus/minus 20°F within
setpoint), press the
switch once to display the temperature of the cooking oil or shortening as
sensed by the temperature probe.
2. Press the
switch twice to display the setpoint.
3. Note the temperature on the thermometer or pyrometer. All three readings should be within ±
5ºF (2ºC) of each other. If not, contact a Factory Authorized Service Center for assistance.
Clean Gas Valve Vent Tube
(NOTE: This check applies only to Non-CE units without electronic ignition.)
1. Carefully unscrew the vent tube from the valve (NOTE: The vent tube may be straightened.)
5-3
2. Pass a piece of ordinary binding wire (.052 inch diameter) through the tube to remove any
obstruction.
3. Remove the wire and blow through the tube to ensure it is clear.
4. Reinstall the tube and bend it so that the opening is pointing downward.
SEMI-ANNUAL CHECKS AND SERVICES
Check Burner Manifold Pressure
DANGER
This task should be performed by qualified service personnel only. Contact FASC to
arrange this service.
5.2 FootPrint III Filtration System Preventive Maintenance Checks and Services
Other than daily cleaning of the filter pan with a solution of hot water and detergent and the
recommended Annual/Periodic System Inspection, there are no periodic preventive maintenance
checks and services required for your FootPrint III Filtration System.
If you notice that the system is pumping slowly or not at all, verify that the filter pan screen is on the
bottom of the filter pan, with the paper on top of the screen. If the filter screen and paper are
correctly installed, change the filter paper and verify that the O-ring on the bottom of the filter pan is
present and in good condition.
Immediately after each use, drain the Power Shower completely. If you suspect blockage, unscrew
the clean-out plugs at each corner of the frame. Place the frame in a pan of hot water for several
minutes to melt any accumulation of solidified oil/shortening. Use a long, narrow bottlebrush with
hot water and detergent to clean inside the tubes. If necessary, insert a straightened paper clip or
similar instrument into the holes in the frame to remove any blockages. Rinse, dry thoroughly, and
reinstall the plugs before using.
DANGER
Failure to reinstall the clean-out plugs will cause hot oil/shortening to spray out of
the frypot during the filtering process, creating an extreme burn hazard to personnel.
5.3
Annual/Periodic System Inspection
This appliance should be inspected and adjusted periodically by qualified service personnel as
part of a regular kitchen maintenance program.
Frymaster recommends that this appliance be inspected at least annually by a Factory

Verify that component box components (i.e. computer/controller, transformers, relays, interface
boards, etc.) are in good condition and free from oil migration build-up and other debris. Inspect
the component box wiring and verify that connections are tight and that wiring is in good
condition.
•
Verify that all safety features (i.e. drain safety switches, reset switches, etc.) are present and
functioning properly.
•
Verify that the frypot/cookpot is in good condition and free of leaks and that the frypot/cookpot
insulation is in serviceable condition.
•
Verify that wiring harnesses and connections are tight and in good condition.
Built-In Filtration System
•
Inspect all oil-return and drain lines for leaks and verify that all connections are tight.
•
Inspect the filter pan for leaks and cleanliness. If there is a large accumulation of crumbs in the
crumb basket, advise the owner/operator that the crumb basket should be emptied into a fireproof
container and cleaned daily.
•
Verify that all O-rings and seals (including those on the Power Shower and on quick-disconnect
fittings) are present and in good condition. Replace o-rings and seals if worn or damaged.
•
Check filtration system integrity as follows:
− With the filter pan empty, place each oil return handle, one at a time, in the ON position.
Verify that the pump activates and that bubbles appear in the cooking oil/shortening (or that
gurgling is heard from the Power Shower port) of the associated frypot..
− Close all oil return valves (i.e., place all oil return handles in the OFF position). Verify
proper functioning of each oil return valve by activating the filter pump using the lever on
one of the oil return handle microswitches. No air bubbles should be visible in any frypot (or
no gurgling should be heard from the Power Shower ports).
5-5
−
Verify that the filter pan is properly prepared for filtering, then drain a frypot of oil heated to
350°F (177°C) into the filter pan and close the frypot drain valve. Place the oil return handle
in the ON position. Allow all cooking oil/shortening to return to the frypot (indicated by
bubbles in the cooking oil/shortening or, on units with Power Showers, cessation of oil flow
from the Power Shower). Return the oil return handle to the OFF position. The frypot should
have refilled in no more than 2 minutes and 30 seconds.

CHAPTER 6: OPERATOR TROUBLESHOOTING
6.1
Introduction
This chapter provides an easy reference guide to some of the common problems that may occur
during the operation of your equipment. The troubleshooting guides that follow are intended to help
you correct, or at least accurately diagnose, problems with your equipment. Although the chapter
covers the most common problems reported, you may encounter problems that are not covered. In
such instances, the Frymaster Technical Services staff will make every effort to help you identify
and resolve the problem.
When troubleshooting a problem, always use a process of elimination starting with the simplest
solution and working through to the most complex. Most importantly, always try to establish a clear
idea of why a problem has occurred. Part of your corrective action involves taking steps to ensure
that it doesn’t happen again. If a controller malfunctions because of a poor connection, check all
other connections while you’re at it. If a fuse continues to blow, find out why. Always keep in mind
that failure of a small component may often be indicative of potential failure or incorrect functioning
of a more important component or system.
Some of the troubleshooting actions recommended in this chapter involve removing suspect
components and substituting components that are known to be good. Whenever this in indicated,
refer to Sections 6.7 for specific instructions
If you are in doubt as to the proper action to take, do not hesitate to call the Frymaster Technical
Service Department or your local Frymaster Factory Authorized Service Center for assistance.
Before calling a servicer or the Frymaster HOTLINE (1-800-551-8633):
•

Replacing the Ignition Module Fuse in Units with Electronic Ignition
1. Disconnect the fryer from the electrical supply and remove the two screws in the upper corners
of the control panel. Swing the panel open from the top, allowing it to rest on its hinge tabs.
2. Locate the 3-amp ignition module fuse (refer to illustration below) and, using a fuse-puller,
remove and replace it with a new fuse.
Ignition Module
Depending upon when the unit was
manufactured, full vat units may have either
one or two ignition modules. If there is only
one ignition module, the fuse will be mounted
on the interface board.
For units in which the ignition
module has no fuse, replace the
upper fuse on the interface board.
Dual vat units and some full vat units will have
two ignigiton modules. Look for the fuse on
the left side of the module. If there are no
fuses on the modules, the fuse will be on the
interface board.
3. Close the panel, replace the control panel screws, and reconnect the fryer to the electrical supply.
6-6
6.7
Replacing the Controller or Controller Wiring Harness
1. Disconnect the fryer from the electrical supply.
2. Remove the two screws in the upper corners of the control panel and swing the panel open from
the top, allowing it to rest on its hinge tabs.
3. Disconnect the wiring harness from the back of the controller and, if replacing the harness,
disconnect it from the interface board (see photo on following page).
4. If replacing the controller, disconnect the ground wire and remove the controller by lifting it
from the hinge slots in the control panel frame.
5. Reverse the procedure to install a new controller or wiring harness.
