1.5 Equipment Description

H50 Series high-efficiency gas fryers employ a unique infrared burner system that uses up to 43%
less energy to cook the same volume as conventional fryers. Models in this series include MJH50,
FMH50, and FPH50 variants. MJH50 variants have no built-in filtration system. FMH50 variants
have a built-in Filter Magic II filtration system. The Filter Magic system is housed in its own
cabinet, which may be attached to either side of a fryer and which can be located anywhere in a
battery of fryers. The FPH50 variants have a built-in FootPrint III filtration system that is located
underneath the fryer to conserve floor space. (In batteries of fryers, the FootPrint III system is
always located under the leftmost two fryers.)
All H50 Series fryers are of an open-pot design with no tubes and have a hand-sized opening into the
deep cold zone, which makes cleaning the stainless frypot quick and easy.

Heating is supplied by a pair of infrared burner assemblies mounted on each side of the frypot.
Combustion air for the burners is supplied by a dedicated blower mounted on the front of the frypot.
H50 Series fryers can be configured for natural gas, propane (LP), or manufactured gas, as required
by the customer.

Each frypot is equipped with a temperature probe for precise temperature control.

All H50 Series fryers come standard with electronic ignition, melt cycle, and boil-out mode. Control
options include Computer Magic III computers, solid-state (analog) controllers, digital controllers,
and basket lift timers.

All fryers in this series require an external source of AC electrical power. Units can be configured
for voltages ranging from 120 VAC to 220 VAC.

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.

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.

Upon arrival, inspect the cooker carefully for visible or concealed damage. (See Shipping Damage
Claim Procedure in Chapter 1.)

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.

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.

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.

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 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.

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.

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 when the appliance consumes more than 120,000 BTU per hour.

For installations in the United States, 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.

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.

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!

2-2

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.

AUSTRALIAN REQUIREMENTS

To be installed in accordance with AS 5601 / AG 601, local authority, gas, electricity, and any other
relevant statutory regulations.

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.

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.
If necessary, the user should consult the dealer or an experienced radio and television technician for
additional suggestions.

2.2 Caster/Leg Installation

Depending upon the specific configuration ordered, your fryer may have been shipped without
installed casters or legs. DO NOT INSTALL THIS APPLIANCE WITHOUT CASTERS OR

LEGS. If the appliance requires the installation of casters or legs, install them in accordance
with the instructions included in your accessory package.

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

2-3

times when the fryer is in use. The restraining cable and installation instructions are packed with

O

O

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 fryers equipped with

casters or anchor straps on fryers equipped with legs. Follow the instructions in the accessory
pack to install the chains or straps.

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.

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 hood be 24
in. (600 mm) when the appliance consumes more than 120,000 BTU per hour. NOTE: There
are no built-in leveling devices on fryers equipped with casters. 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 solid-state (analog) controls, verify that the power and heat

lights are lit.

• For fryers having computer or digital displays, verify that the display indicates CYCL.

c. Place the fryer power switch in the OFF position. Verify that the power and heat lights are

out, or that the display is blank.

5. Refer to the data plate on the inside of the fryer door to determine if the fryer burner is

configured for the proper type of gas before connecting the fryer quick-disconnect device or
piping from the gas supply line.

6. Verify the minimum and maximum gas supply pressures for the type of gas to be used in

accordance with the accompanying tables.

2.4 Connection to Gas Line

DANGER
Before connecting new pipe to this appliance, the pipe must be blown out thor­oughly to remove all foreign material. Foreign material in the burner and gas con­trols will cause improper and dangerous operation.

DANGER
When pressure-testing incoming gas supply lines, disconnect the fryer from the gas
line if the test pressure will be ½ PSIG (3.45 kPa, 13.84 inches W.C.) or greater to
avoid damage to the fryer’s gas tubes and gas valve(s).

DANGER
All connections must be sealed with a joint compound suitable for the gas being
used and all connections must be tested with a solution of soapy water before light­ing any pilots.

Never use matches, candles, or any other ignition source to check for leaks. If gas
odors are detected, shut off the gas supply to the appliance at the main shut-off
valve and immediately contact the local gas company or an authorized service
agency for service.

DANGER
“Dry-firing” your unit will cause damage to the frypot and can cause a fire. Always
ensure that melted shortening, cooking oil, or water is in the frypot before firing the
unit.

The size of the gas line used for installation is very important. If the line is too small, the gas
pressure at the burner manifold will be low. This may cause slow recovery and delayed ignition.
The incoming gas supply line should be a minimum of 1½” (38 mm) in diameter. Refer to the chart
on the following page for the minimum sizes of connection piping.

1. Connect the quick-disconnect hose to the fryer quick-disconnect fitting under the front of the
fryer and to the building gas line.

NOTE: Some fryers are configured for a rigid connection to the gas supply line. These units
are connected to the gas supply line at the rear of the unit.

When using thread compound, use very small amounts on male threads only. Use a pipe thread
compound that is not affected by the chemical action of LP gases (Loctite™ PST56765 Sealant
is one such compound). DO NOT apply compound to the first two threads. Doing so may allow
some of the compound to enter the gas stream, resulting in clogging of burner orifices and/or the
control valve.

2. Open the gas supply to the fryer and check all piping, fittings, and gas connections for leaks. A
soap solution should be used for this purpose.

3. Close the fryer drain valve and fill the frypot with water and boil-out solution to the bottom
OIL LEVEL line at the rear of the frypot. Light the fryer and perform the boil-out procedures
that are described in the “Lighting Instructions” and “Boiling Out the Frypot” topics found in
Chapter 3 of this manual.

DANGER
“Dry-firing” your unit will cause damage to the frypot and can cause a fire. Always
ensure that melted shortening, cooking oil, or water is in the frypot before firing your
unit.

4. The burner manifold pressure should be checked at this time by the local gas company or an

authorized service agent. The tables below and on the following page list the burner manifold

2.5 Converting to Another Gas Type

DANGER
This appliance was configured at the factory for a specific type of gas. Converting
from one type of gas to another requires the installation of specific gas-conversion
components.

Switching to a different type of gas without installing the proper conversion
components may result in fire or explosion. NEVER ATTACH THIS APPLIANCE TO A
GAS SUPPLY FOR WHICH IT IS NOT CONFIGURED!

Conversion of this appliance from one type of gas to another should only be
performed by qualified, licensed, and authorized installation or service personnel, as
defined in Section 1.7 of this manual.

H50 Series Fryers manufactured for Non-CE countries use different burners for each type gas. The
burners in fryers built for Propane gas have a special gray-colored coating on the burner tiles to
enable them to withstand the higher caloric value of the Propane gas. Burners designed for use in
Propane units may be used in natural gas applications, but not vice versa.

3.1 Start-Up Procedure

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
If this is the first time the fryer is being used after installation, refer to Section 3.2,
Boil-Out Procedure.

CAUTION
The cooking oil/shortening capacity of the H50 Series fryer is 50 lbs. (25 liters) at
70ºF (21ºC) for a full-vat and 25 lbs. (12.5 liters) at 70ºF (21ºC) for each half of a
dual-vat.

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.

WARNING
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.

Lighting the Fryer

1. Press the computer/controller ON/OFF switch to the OFF position.

The optimum burn is a bright orange-red glow. If a blue flame is observed, or if there are dark
spots on a burner face, the air/gas mix requires adjustment. Adjustment procedures are different
for CE and Non-CE units.

Adjusting Air/Gas Mix:

Non-CE Units and CE Units Built After April 1999

On the side of the blower housing opposite the motor is a plate with one or two locking nuts.
Loosen the nut(s) enough to allow the plate to be moved, then adjust the position of the plate to open
or close the air intake opening until a bright orange-red glow is obtained. Carefully hold the plate in
position and tighten the locking nut(s).

3-3

Adjusting Air/Gas Mix:

CE Units Built Before May 1999

CE units built before May 1999 are equipped with a shield assembly in front of the blowers. An air
shutter plate on the face of the shield assembly regulates the amount of airflow to the blower intake.
To adjust the shutter plate, loosen the locking screws and slide the shutter to the left or right as
necessary to obtain a bright orange-red glow. Carefully hold the shutter plate in position and tighten
the locking screws.

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.

1. Before lighting the burners, close the fryer drain valve(s) and fill the frypot to the bottom

OIL-LEVEL line with a mixture of cold water and automatic dishwasher detergent.

2. For units equipped with a Solid State (Analog) controller, set the temperature knob to 195°F

(91°C)

For units equipped with a Digital Controller, use the setpoint up/down keys to adjust the set-
point to 195°F (91°C)

CHAPTER 4: FILTRATION INSTRUCTIONS

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.

4.1 Draining and Manual Filtering

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
Allow oil/shortening to cool to 100°F (38°C) before draining into an appropriate
container for disposal.

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
When draining oil/shortening into a disposal unit or portable filter unit, do not fill
above the maximum fill line located on the container.

If your fryer is not equipped with a built-in filtration system (FootPrint III or Filter Magic II), 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 using the Frymaster
Shortening Disposal Unit (SDU). The SDU is available through your local distributor.)

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 Fryer’s Friend (poker-like tool) 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.

4. 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 the shortening down into the bottom of the
frypot. DO NOT operate the fryer with a solid 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 Built-In Filtration System Operation

Both the FootPrint III (FP III) and Filter Magic II (FM II) filtration systems allow the cooking oil or
shortening in one frypot to be safely and efficiently filtered while the other frypots in a battery re­main in operation. Although different in design and appearance, the operation of the FootPrint III
and Filter Magic II systems is identical. Operation of the FootPrint III system is illustrated in this
discussion, but the steps described apply equally to the Filter Magic II system.

Most reported problems with these systems have been found to be caused by improper operation.
Careful attention to the step-by-step instructions that follow will ensure that your system operates as
intended.

PREPARING THE FILTER UNIT FOR USE

1. Pull the filter unit from the cabinet, open the cover, remove the crumb tray, and remove the pa-

per hold-down ring.

4-2

2. Remove used filter paper if present, and clean the pan as necessary. Verify that the metal filter

screen is in the bottom of the pan, and then lay a clean sheet of filter paper over the top of the
pan, overlapping on all sides.

3. 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.

4. Sprinkle filter powder over the filter paper. (For powder quantity, see the filter powder

manufacturer’s instructions.) Replace the crumb tray in the filter pan and close the cover.

5. Push the filter pan back into the fryer, positioning it all the way to the back of the cabinet.
(When the FM II filter assembly is properly positioned, the green HEATER ON indicator will
light.)

4-3

OPERATION OF THE FILTER UNIT

CAUTION
Never operate the filter unit unless the cooking oil in the fryers has been brought up
to cooking temperature.

1. To filter the cooking oil, turn the fryer

power OFF, then open the drain valve on
the fryer you have selected to be filtered.
If necessary, use the Fryer's Friend steel
rod to clear the drain from inside the
frypot.

Push handle to

the right to open..

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.

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.

2. When the frypot is empty, use a scouring tool to remove sediment on the sides of the frypot.

WARNING

When cleaning the inside of the frypot, avoid striking the high limit thermostat and
temperature probe or operating thermostat.

3. Snap the Power Shower into the frypot.

4-4

DANGER

DO NOT operate the filter without the Power Shower in place unless unit is configured with a
rear flush option. Hot oil will spray out of the fryer and may cause injury.

4. After all oil has drained from the pot, push

the filter handle down and to the rear to
start the pump and begin the filtering
process. (For units equipped with a rear­flush option, position the control lever to
either the Power Shower or Rear Flush
position.) There may be a slight delay
before the pump activates.

5. After the oil is filtered, close the drain

valve and allow the fryer to refill. Let the
filter run 10 to 12 seconds after bubbles
appear in the oil to clear the lines and
prevent hardening of shortening in the
lines.

Push filter

H50 SERIES GAS FRYERS

CHAPTER 5: PREVENTIVE MAINTENANCE

5.1 Fryer Preventive Maintenance Checks and Service

DAILY CHECKS AND SERVICE

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

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.

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.

WEEKLY CHECKS AND SERVICE

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. This deposit must be periodically removed to maintain your fryer’s
efficiency.

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 a built-in 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 using our Shortening Disposal Unit (SDU). The SDU is
available through your local distributor.)

1. Place the fryer power switch in 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.

5-1

2. Position a Shortening Disposal Unit (SDU) or a metal stock pot with a sealable cover under the

drainpipe. (The pot 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 our 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 SDU or pot.

3. Open the drain valve slowly to avoid splattering. If the drain valve becomes clogged with food

particles, use the Fryer’s Friend cleanout rod to clear the blockage.

DANGER
DO NOT insert the cleanout rod into the drain from the front to unclog the valve. Hot
oil/shortening will rush out, creating an extreme hazard.

DO NOT hammer on the drain valve. This will damage the drain valve ball and
prevent the valve from sealing securely, resulting in a leaky valve.

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 a solution of automatic dishwasher

detergent and water to the bottom OIL-LEVEL line. (Frymaster recommends the use of
Frymaster Boil-Out Solution, available through your local distributor, for best results.)

6. Set the thermostat to 195ºF (91ºC) or program the computer for Boil-Out (see separate Frymas-

ter Fryer Controllers User’s Manual) and simmer the solution for 1 hour.

WARNING
Never leave the fryer unattended during this process. If the solution overflows,
press the ON/OFF switch to the OFF position immediately.

7. After the solution has simmered for 1 hour, press the ON/OFF switch to the OFF position and

allow the solution to cool.

8. Drain the solution into a suitable container (NOT the built-in filtration system filter pan or

the Shortening Disposal Unit) and thoroughly wipe the frypot with a clean towel.

9. Close the drain valve and fill the frypot with clean, cold water and drain into a suitable container

(NOT the built-in filtration system filter pan or the Shortening Disposal Unit). Repeat the
rinse process again, and then wipe frypot with a clean, dry towel.

DANGER
Ensure that the frypot is completely free of water before filling with cooking oil or
shortening. When the oil or shortening is heated to cooking temperature, water in
the frypot will cause splattering.

Clean Detachable Parts and Accessories

5-2

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.

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.

MONTHLY CHECKS AND SERVICE

Check Calibration of Analog Controller Thermostat Control Knob

(This check applies only to units equipped with Analog Controllers)

1. Insert a good-grade thermometer or pyrometer probe into the oil/shortening, with the end touch-

ing the fryer temperature-sensing probe and set the thermostat knob to frying temperature.

2. After the set temperature is reached, 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. 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.

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). If calibration cannot be obtained for any reason, call a Factory

Authorized Service Center for assistance.

5. Remove the thermometer or pyrometer.

Check Computer Magic III Set Point Accuracy

(This check applies only to units equipped with Computer Magic III Controllers.)

1. Insert a good-grade thermometer or pyrometer probe into the oil/shortening, with the end touch­ing the fryer temperature-sensing probe.

5-3

2. When the computer display shows a series of four dashes “----” with no dot between the first and
second dashes (indicating that the frypot contents are within the cooking range), press the
switch once to display the temperature of the cooking oil or shortening as sensed by the
temperature probe.

3. Press the

switch twice to display the set point.

4. 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.

QUARTERLY CHECKS AND SERVICE

Clean Combustion Air Blower Assembly

A sheet metal shield or shield assembly prevents inadvertent access to the blower assembly. The
specific design varies depending upon the particular configuration of the fryer and the country for

CE units built through April 1999 are equipped with a shield assembly in front of the blowers. An
air shutter plate on the face of the shield assembly regulates the amount of airflow to the blower in­take. To adjust the shutter plate, loosen the locking screws and slide the shutter to the left or right as
necessary to obtain a bright orange-red glow. Carefully hold the shutter plate in position and tighten
the locking screws.

5.2 Built-in Filtration System Preventive Maintenance Checks and Service

WARNING

Never operate the filter system without cooking oil/shortening in the system.

WARNING

Never use the filter pan to transport old cooking oil/shortening to the disposal area.

WARNING

Never drain water into the filter pan. Water will damage the filter pump.

There are no periodic preventive maintenance checks and services required for your FootPrint III or
Filter Magic II Filtration Systems other than daily cleaning of the filter pan with a solution of hot
water and detergent.

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. Verify that the o-ring(s) are present and
in good condition. For FootPrint III units, there is a single o-ring located on the bottom of the filter
pan. For Filter Magic II systems, there is an o-ring on the bottom of the pan and two on the fitting at
the inside back of the cabinet.

Immediately after each use, drain the Power Shower completely. If oil is leaking at the point where
the Power Shower plugs into the frypot, verify that the o-ring and gasket on the connection fitting
are present and in good condition. 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 similarly sized
wire into the holes in the frame to remove any solidified shortening or other blockages. Rinse with
hot water, dry thoroughly, and reinstall the plugs before using.

O-RING

CLEAN-OUT PLUGS

GASKET

DANGER
Failure to reinstall the clean-out plugs in the Power Shower 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
Authorized Service Technician as follows:

Fryer

• Inspect the cabinet inside and out, front and rear for excessive oil build-up and/or oil migration.

• Verify that the flue opening is not obstructed by debris or accumulations of solidified oil or

shortening.

• Verify that burners and associated components (i.e. gas valves, pilot assemblies, ignitors, etc.)

are in good condition and functioning properly. Inspect all gas connections for leaks and verify
that all connections are properly tightened.

• Verify that the burner manifold pressure is in accordance with that specified on the appliance’s

rating plate.

• Verify that the temperature and high-limit probes are properly connected, tightened and

functioning properly, and that probe guards are present and properly installed.

• 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 the Filter Magic

quick-disconnect fitting) are present and in good condition. Replace o-rings and seals if worn or
damaged.

5-9

• 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).

− 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 [phone]):

• Verify that electrical cords are plugged in and that circuit breakers are on.

• Verify that gas line quick-disconnects are properly connected.

• Verify that any gas line cutoff valves are open.

• Verify that frypot drain valves are fully closed.

DANGER

Hot cooking oil/shortening will cause severe burns. Never attempt to this appliance
when filled with hot cooking oil/shortening or to transfer hot cooking oil/shortening from
one container to another.

DANGER

This equipment should be unplugged when servicing, except when electrical circuit
tests are required. Use extreme care when performing such tests.

This appliance may have more than one electrical power supply connection point.
Disconnect all power cords before servicing.

Inspection, testing, and repair of electrical components should be performed by an
authorized service agent only.

6.4 Troubleshooting the Built-in Filtration System

PROBLEM PROBABLE CAUSES CORRECTIVE ACTION

Failed controller.

A. Thermal overload switch has

tripped on an overheated motor.

If available, substitute a controller
known to be working for the suspect
controller. If the fryer functions
correctly, order replacement from
FASC.

A. If the pump runs normally after

resetting the thermal overload
switch, the pump was overheated.

Pump won’t start.

OR

Pump stops during

filtering.

Test: If the pump stopped
suddenly during the filtering
process, especially if after several
filtering cycles, the pump motor
has probably overheated. Place
the filter handle in the OFF
position, allow the pump to cool
for at least 45 minutes, and then
press the reset button on the pump
motor. Attempt to activate the
pump.

B. Failed filter handle microswitch.

Test: If this is a multi-pot fryer,
attempt to operate the pump using
a different handle. If the pump
starts, the handle microswitch is
either out of alignment or has
failed.

When the handle is placed in the
ON position, the lever on the
microswitch should be firmly
pressed against the switch. If so,
the switch has failed. If not, the
switch is loose and/or misaligned.

Always filter with the cooking
oil/shortening at or near frying
temperature.

Allow the pump motor to cool off
for about ten minutes after
filtering two full frypots one after
the other.

Check the filter paper between
filterings. Replace the paper if
there is a large accumulation of
sediment.

B. If the switch is loose, tighten the

nuts and bolts holding it in place,
ensuring that when the handle is
placed in the ON position, the
lever on the microswitch is
pressed firmly against the switch.

If the switch has failed, call
FASC.

6-6

PROBLEM PROBABLE CAUSES CORRECTIVE ACTION

(Continued from

previous page.)

Pump starts, but no
transfer takes place

or the transfer is

very slow.

C. Pump blockage.

Test: Close the drain valve. Place
the filter handle in the OFF
position, allow the pump to cool
for at least 45 minutes, and then
press the reset button on the pump
motor. Pull the filter pan from the
unit and then activate the pump.
If the pump motor hums and then
stops, the pump is blocked.

A. Cooking oil/shortening is too cold

for filtering.

B. Improperly installed or prepared

filter pan components.

Test: Close the drain valve.
Move the filter handle to the OFF
position, pull the filter pan (and
Power Shower, if so equipped)
from the unit. Move the filter
handle to the ON position.

If a strong stream of air is being
pumped out of the oil return port
(or the Power Shower port), the
problem is with the filter pan
components.

(Continued on following page.)

C. Pump blockages are usually

caused by sediment build-up in
the pump due to improperly sized
or installed filter paper and failure
to use the crumb screen. Call
FASC to have blockage cleared.

Ensure that filter paper is of the
proper size and is installed
properly, and that the crumb
screen is used.

A. To properly filter, the oil or

shortening should be at or near
350°F (177°C). At temperatures
lower than this, the oil/shortening
becomes too thick to pass through
the filter medium easily, resulting
in much slower oil return and
eventual overheating of the filter
pump motor. Ensure that the
cooking oil/shortening is at or
near frying temperature before
draining into filter pan.

B. Remove the oil from the filter pan

and replace the filter paper,
ensuring that the filter screen is in
place under the paper.

C. If this does not correct the

problem, the filter tube suction
tube is probably blocked. Remove
the blockage using a thin, flexible
wire. If unable to remove the
blockage, call FASC.

6-7

PROBLEM PROBABLE CAUSES CORRECTIVE ACTION

C. Improperly installed or prepared

filter pan components.

D. Remove the oil from the filter pan

and replace the filter paper,
ensuring that the filter screen is in
place under the paper.

If this does not correct the
problem, the filter tube suction
tube is probably blocked. Remove
the blockage using a thin, flexible
wire. If unable to remove the
blockage, call FASC.

D. Verify that filter connection

o-rings are present and in good
condition.

Replace the filter paper, ensuring
that the filter screen is properly
positioned under the paper.

If using Magnasol filter assembly,
verify that o-ring is present and in
good condition on filter screen
fitting.

(Continued from

previous page.)

Test: Close the drain valve.
Move the filter handle to the OFF
position, pull the filter pan (and
Power Shower, if so equipped)
from the unit. Move the filter
handle to the ON position.

If a strong stream of air is being
pumped out of the oil return port
(or the Power Shower port), the
problem is with the filter pan
components.

D. Improperly installed or prepared

filter pan components.

Test: Close the drain valve.
Move the filter handle to the OFF
position, and pull the filter pan
(and Power Shower, if so
equipped) from the unit. Move
the filter handle to the ON
position.

If a strong stream of air is being
pumped out of the oil return port
(or the Power Shower port), the
problem is with the filter pan
components.

A. Plugged openings or solidified

shortening in the Power Shower.

Power Shower is not

spraying properly.

Test: Look for oil/shortening
squirting out around the Power
Shower gasket but not coming out
of the holes around the frame. If
so, Power Shower is obstructed.

B. Missing/worn o-rings and gasket

on Power Shower.

C. Missing paper in filter pan. (This

causes too much pressure in the
oil return lines, resulting in a
strong flow through the Power
Shower, but also squirting of oil
from around the gasket.)

6-8

A. Clean the Power Shower per

instructions in Chapter 5 of this
manual.

B. Verify that o-rings and gasket are

present and in good condition.

C. Verify that filter paper is properly

installed in the filter pan.

6.5 Troubleshooting the Basket Lift

PROBLEM PROBABLE CAUSES CORRECTIVE ACTION

Basket lift

movement is jerky

and/or noisy.

Basket lift rods need lubrication.

Lubricate basket lift rods with
Lubriplate™ or equivalent light white
grease.

6.6 Replacing the Ignition Module Fuse

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 the 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.

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 and replace the control panel screws.

4. Reconnect the fryer to the electrical supply.

For units in which the ignition
module has no fuse, replace the
upper fuse on the interface board.
