CF SERIES GAS FRYERS
CHAPTER 1: INTRODUCTION
1.5 Equipment Description
CF Series gas fryers are specifically designed for high volume frying, especially fish, chicken and
other breaded products. Models in this series include FMCF, FMCFE, FMCFEC, MJCF, MJCFE,
MJCFEC, KJ3FC and J65X variants. (The J65X variant is a drop-in unit without cabinetry.) Fryers
in this series may be equipped with built-in Filter Magic filtration systems (FMCF variants), or may
be configured for manual filtration (MJCF variants). All models may be configured for electrical
power supplies ranging from 120 to 240 VAC.
FMCF, MJCF AND J65X models utilize a combination gas valve to control the burner, but do not
require an external AC power source. An AC power source is required for these models when
equipped with built-in filtration systems.
FMCFE, KJ3FC and MJCFE models utilize a combination gas valve to control the burner and
require an external AC power source. The electrical power supply to the gas valve is controlled by a
manually-operated thermostat controller or a computer/controller. The FMCFEC and MJCFEC
models are equipped with Computer Magic III.5 computers. The KJ3FC variants are equipped with
user-supplied or KFC-1 computers.
All models 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.
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. 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, which 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 frontcontrolled 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.
CF 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 thermostat controls, solid state (analog) controllers, digital controllers, KFC-1,
Fastron or Computer Magic III.5 computers. Each type is covered in a separate manual provided
with your equipment.

CF SERIES GAS FRYERS
CHAPTER 2: INSTALLATION INSTRUCTIONS
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. If a flue deflector is included with the fryer, ensure that the flue deflector
is installed as per the instruction sheet provided. It is recommended that a flue deflector is used for fryers
installed near a wall cavity that contains combustible materials. 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 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 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 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.
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.

CHAPTER 2: INSTALLATION INSTRUCTIONS
CE Standard
CE regulations require a combustion air supply of 2m3/h per kW per fryer. (See rating plate affixed
to door for kW rating.)
1. Connect the quick-disconnect hose to the fryer quick-disconnect fitting under the fryer and to the
building gas line. The gas inlet connection will be up to 1.5” NPT (38.1mm), depending on the
number of fryers in the battery. The gas connection point will be about 8” (200mm) from the
floor. The left-to-right position will vary according to the number of fryers in the battery.
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 PST567 sealant is one
such compound). DO NOT apply compound to the first two threads. Applying compound to the
first two threads will cause clogging of the burner orifices and control valve.
2. Open the gas-supply valve to the fryer and check all piping, fittings, and gas connections for
leaks. A soap and water solution should be used for this purpose.
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.
3. Close the fryer drain valve and fill the frypot with water and boil-out solution to the bottom OILLEVEL 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. (non-KFC co-branded locations only)
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. (In KFC co-branded locations, oil MUST be used rather than water.)
4. The burner manifold pressure should be checked at this time by the local gas company or an
authorized service agent. The tables on page 2-5 indicate the proper burner manifold pressures.

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 oil 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 oil.
DANGER
NEVER attempt to drain oil from the fryer with the burner lit! Doing so will result in a
flash fire if the oil splashes onto the burner. Applying burner heat to an empty frypot
will severely damage the frypot and void warranties.
DANGER
Allow oil 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 oil must be drained into another suitable
container. For safe, convenient draining and disposal of used oil, 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 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 sealed cover under the drainpipe. The metal container must be
able to withstand the heat of the oil and hold hot liquids. If you intend to reuse the oil, use a
Frymaster filter cone holder and filter cone when a filter machine is not available.
4-1
CF SERIES GAS FRYERS
CHAPTER 4: FILTRATION INSTRUCTIONS
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 becomes 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 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, clean all food particles and residual oil from the frypot. If the fryer is
equipped with a float switch, clean it at this time. The float switch prevents frypot damage in the
event the power switch is not OFF while draining used oil. The float switch must be cleaned on
a regular basis to ensure proper operation. Use caution as frypot residue can cause severe burns if
it contacts 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 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.

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, with the end touching the fryer
temperature probe.
2. When the computer displays
with no red 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
±5°F (2°C) of each other. If not, contact a Factory Authorized Service Center for assistance.
Clean Gas Valve Vent Tube
1. Carefully unscrew the vent tube from the valve. (NOTE: The vent tube may be straightened.)
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 tube and bend it so that the opening is pointing downward.

5.2 Filter Magic II Filtration System Preventive Maintenance Checks and
Services
The Filter Magic II Filtration System requires daily cleaning of the inner and outer filter pans with a
solution of hot water and detergent. Turn the filter pan upside down and slightly elevate the end
to allow all water to drain from the suction tube.
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.
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. 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 cause hot oil to spray out of
the frypot during the filtering process, creating a 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 debris or accumulations of solidified oil do not obstruct the flue opening.

Verify that burners and associated components (i.e. gas valves, pilot assemblies, igniters, 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 is in good condition and free of leaks and that the frypot insulation is in
serviceable condition. Verify that the frypot tube diffusers are present and in good condition (i.e.
no visible deterioration or damage).

Verify that wiring harnesses and connections are tight and in good condition.
5-6
CF SERIES GAS FRYERS
CHAPTER 5: PREVENTATIVE MAINTENANCE
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 oil (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 oil to return to the frypot (indicated by bubbles in the oil 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 may occur during
the operation of your equipment. The troubleshooting guides in this chapter 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 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.
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 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.
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.
If the power cord(s) need replaced call your local Frymaster Factory Authorized Servicer for
assistance. The power cord(s) should only be replaced by a Frymaster Factory Authorized Servicer.
DANGER
Hot oil will cause severe burns. Never attempt to move this appliance when filled hot
oil or to transfer hot oil 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 including power cord(s)
should be performed by an authorized service agent only.
