MASTER JET SERIES ATMOSPHERIC GAS FRYERS

CHAPTER 1: INTRODUCTION

1.5.2 Model Applications (cont.)

All models except J1C Series fryers may be equipped with optional built-in filtration systems. All
models except J1C and MJ35 Series fryers may be configured for electrical power supplies ranging
from 120 to 240 VAC.

All models are of an open-pot design and have a hand-sized opening into the deep cold zone, which
makes cleaning the stainless frypot quick and easy.

Fryers equipped with built-in filtration systems are shipped completely assembled. Fryers without
built-in filtration require installation of legs or optional casters at point of use (J1C Series not
available with casters). All fryers are shi pped with a pack age of standard accessories. E ach fr yer is
adjusted, tested, and inspected at the factory before crating for shipment.

Frypots are constructed of welded, heavy-gauge cold-rolled steel or stainless steel. Heating is
supplied by a burner assembly having multiple gas jets, which are focused on ceramic targets located
around the lower side of the frypot. The burner assembly can be confi gured for natural gas, propan e,
or manufactured gas. The frypot is drained with a manual ball valve.

Master Jet Series Atmospheric fr yers are equipped with a thermostat probe for preci se 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.

Master Jet Series Atmospheric fryers may be equipped with an optional melt cycle feature (not
applicable to J1C and MJ35 Series), 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 when using
solid shortening.

Controls on Master Jet Series Atmospheric fryers vary dep ending on the model and configuration
purchased. Control options can include thermostat controls, solid-state (analog) controllers, digital
controllers, or Computer Magic III.5 computers. Not all models are available with all controller
options. Each type is covered in detail in the separate Frymaster Fryer Controllers User’s Manual

MASTER JET SERIES ATMOSPHERIC GAS FRYERS

CHAPTER 2: INSTALLATION INSTRUCTIONS

2.1 General Installation Requirements (cont.)

CLEARANCE AND VENTILATION

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.

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.

One of the most important considerations of efficient fryer operation is ventilation. Ensure 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 fr yer 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 45 degrees. Place a drip tray beneath the lowest
edge of the filter. For U.S. installation, NFPA standard No. 96 states, "A minimum distance of 1 8
inches (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 inches (600 mm) from the flue

outlet to the bottom edge of the filter when the appliance consumes more than 120,000 BTU per
hour.

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.

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.

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.

Applying burner heat to an empty frypot will severely damage the frypot and void

warranties.

DANGER

Allow oil or shortening to cool to 100°F (38°C) or lower before draining to an

appropriate container for disposal.

If the fryer is not equipped with built-in filtration, 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 L.L.C. 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.

4-1

MASTER JET SERIES ATMOSPHERIC GAS FRYERS

CHAPTER 4: FILTRATION INSTRUCTIONS

4.1 Draining and Manual Filtering (cont.)

2. Position a metal container with a sealed cover under the dr ainpipe. The metal container must be
able to withstand the heat of the cooking oil or shortening, and hold hot liquids. If you intend to
reuse the oil or shortening, use a Frymaster filter cone holder and filter cone 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.

3. Open the drain valve slowly to avoid splattering. If the drain valve beco mes clogged with food
particles, use the Fryer’s Friend (poker-like tool) to clear the blockage.

DANGER

DO NOT insert anything into the drain from the front to unclog the valve. Hot

oil/shortening will rush out, creating an extreme hazard.

WARNING

DO NOT hammer on the drain valve with the Fryer’s Friend. This will damage the

drain valve ball and prevent the valve from sealing securely, resulting in a leaky

valve.

4. After draining the oil or shortening, clean all food particles and r esidual oil or shortening from
the frypot. Use caution as frypot residue can cause severe burns if it contacts bare skin.

5. Close the drain valve se curely and fill the fr ypot 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 cool-zone and the bottom of the

frypot. DO NOT operate the fryer with a block of shortening sitting in the upper

portion of the frypot. Irreparable damage to the frypot and a potential flash fire will

result.

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 (Fryers with Computers Only)

Recovery Time is the amount of time it takes the fryer to increase the frypot temperature from 250°F
(121°C) to 300°F (149°C). It is a measure of the fryer’s efficiency, and should be no more than 2
minutes and 30 seconds for MJ45 Series fryers, and 3 minutes and 30 seconds for MJCF Series
fryers. The recovery time on models having CM III.5 computers is automatically measured by the
computer.

To view the recovery time on models equipped with CM III.5 computers, press the Program Mode
switch

. will appear in the left display. Enter the code number

(1652) on

the number keys. The latest recovery time will appear in both displays for 5 seconds.

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

DANGER

Allow oil/shortening to cool to 100°F (38°C) or lower before draining to an

appropriate container for disposal.

If your fryer is not equipped with the built-in Filter Magic II 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 our shortening disposal
unit (SDU). The SDU is available through your local distributor.

As with the frypot, a deposit of carbonized oil/shortening will accumulate on detachable parts and
accessories such as baskets, sediment trays, or fishplates

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/Solid State (Analog) Controller Temperature Control Knob

[NOTE: This check applies only to units equipped with Thermostat or Solid State (Analog)
Controllers.]

1. Ensure frypot is filled with cooking oil or liquid shortening.

2. Set the temperature control knob to frying temperature.

3. Let the burner cycle on and off automatically three times in order for the cooking oil/shortening

temperature to become uniform. If necessary, stir to get all shortening in the bottom of the
frypot melted.

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

touching the fryer temperature probe.

5. When the burner starts for the fourth time, the thermometer/pyrometer reading should be within

± 5ºF (2ºC) of the temperature knob setting. If not, calibrate as follows:
a. Loosen the setscrew in the temperature control knob until the knob rotates freely on the 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 tighten the setscrew.
d. Recheck the thermometer/pyrometer reading against the temperature control knob setting the

next time the burner comes on.

e. Repeat steps 4.a. through 4.d. until the thermometer/pyrometer reading and knob setting are

within ± 5ºF (2°C).

If calibration is not possible, contact a Factory Authorized Service Center for service.

5.1 Fryer Preventive Maintenance Checks and Services (cont.)

Check Thermostat Controller Thermostat Calibration

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

1. Ensure frypot is filled with cooking oil or shortening.

2. 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.

3. 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. Contact
a Factory Authorized Service Center (FASC) for service.

Check Computer Magic III Set Point Accuracy

(NOTE: This check applies only to units equipped with Computer Magic III.5 Controllers.)

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

5.2 Filter Magic II Filtration System Preventive Maintenance Checks and

Services

WARNING

Do not run water or boil-out solution through the filtration system. Doing so will

cause irreparable damage to the pump, and the warranty will be voided.

There are no periodic preventive maintenance checks and services required for your Filter Magic II
Filtration System other than daily cleaning of the filter pan (inner and outer filter pans on CF
systems) with a solution of hot water and detergent. Always remove the filter pan assembly from

the fryer before cleaning with hot water and detergent. After rinsing, turn the filter pan
upside down and slightly elevate the end to allow all water to drain from the suction tube.
Ensure the pan is dried thoroughly before returning to service.

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-rings on the connection fitting
(located inside the cabinet at the back) are present and in good condition. NOTE: With fresh paper
and properly installed O-rings, the system should refill the fryer in 2 to 3 minutes.

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 Power Shower cleanout plugs will allow hot oil to spray out of

the frypot during the filtering process, creating a burn hazard to personnel.

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).

− 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 the more common problems that ma y occur during
the operation of your equipment. The troubleshooting guides in this chapter are intended to help you
correct, or at least accurately diagnose, probl ems with your equipment. Although the chapter cover s
the most common problems reported, you may very well encounter a problem not covered. In such
instances, the Frymaster Technical Service Department will make every effort to help you identify
and resolve the problem. Also, the troubleshooting guides may not be applicable to certain models.

When troubleshooting a problem, always use a process of elimination starting with the simplest
solution and working through to the most complex. Never overlook the obvious. Anyone can forget
to plug a cord into a receptacle or put a piece of filter paper into a filter pan. Don’t assume that you
are exempt from such occurrences.

Most importantly, always try to establish a clear idea of wh y 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.

If you are in doubt as to the proper action to take, do not hesitate to call the Fr ymaster Technical
Service Department or your local Frymaster Factory Authorized Service Center for assistance.

DANGER

Hot cooking oil/shortening will cause severe burns. Never attempt to move this

appliance when filled 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.

6.4 Troubleshooting the Built-In Filtration System

PROBLEM PROBABLE CAUSES CORRECTIVE ACTION

A. If the pump runs normally after

resetting the thermal overload
switch, the pump was overheated.

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

Allow the pump motor to cool off
for about 10 minutes after
filtering two full frypots one after
the other.

Check the filter paper after each
frypot is filtered. Replace the
paper if there is a large
accumulation of sediment.

B. If the switch is loose, tighten the

screws 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.

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.

Pump won’t start.

Pump stops during

filtering.

A. Thermal overload switch has

tripped on an overheated motor.

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.

OR

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
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.

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

ress 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.

6-5

MASTER JET SERIES ATMOSPHERIC GAS FRYERS

CHAPTER 6: OPERATOR TROUBLESHOOTING

6.4 Troubleshooting the Built-In Filtration System (cont.)

PROBLEM PROBABLE CAUSES CORRECTIVE ACTION

A. To properly filter, the oil or

shortening should be at or near
350°F (177°C). At temperatures
lower than this, the oil or
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 or 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 paper
support screen is in place under
the paper.

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

C. Verify that filter connection

O-rings are present and in good
condition.

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

Pump starts, but no

transfer takes place

or the transfer is

very slow.

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.

C. Improperly installed or prepared

filter pan components (cont.).

6.4 Troubleshooting the Built-In Filtration System (cont.)

A. Plugged openings or solidified

shortening in the Power Shower.

Power Shower is not

spraying properly.

Test: Look for oil or shortening
squirting out around the Power
Shower gasket. 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.)

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.
