models are listed in this manual.

2-1

KSCF18G COOL ZONE SERIES GAS FRYERS

CHAPTER 2: IMPORTANT INFORMATION

2.3 Principles of Operation

The incoming gas flows through orifices and is mixed with air in the burners to create the correct
ratio for proper combustion. The mixture is ignited at the front end of each heat tube by the pilot
light. Internal diffusers slow the flame as it goes through the burner tube. This slower and more
turbulent flame gives much better heat transfer to the walls of the tubes, thereby heating the oil more
efficiently.

2.4 Rating Plate

This is attached to the inside of the front door panel. Information provided includes the model and
serial number of the fryer, BTU/hr (kW/hr) input of the burners, outlet gas pressure in inches W.C.
(mbars) and whether the unit has natural (G20/25) or propane (G31) gas orifices.

2.5 Pre-Installation

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.

A. General: Only licensed personnel should install any gas-fired equipment.

1. A manual gas shut-off valve must be installed in the gas supply line ahead of the fryers for
safety and ease of future service.

2. The Frymaster KSCF18G gas fryers require 120 volts (AC) 60-cycle electrical service for
non-CE installation (U.S./Canada/Mexico) and 230 volts (AC) 50-cycle electrical service
for CE/International installations. Fryers are equipped with a 16-3 SJT grounded flexible
power cord for a direct connection to the power supply. Amperage draw for each unit
depends on the accessories supplied with the unit. See detailed instructions packaged with
the fryer line-up.

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 Service Hotline

CHAPTER 2: IMPORTANT INFORMATION

2.6 Air Supply and Ventilation

DANGER

Do not connect this appliance to the gas supply before reviewing each step in this

section.

A. Keep the area around the fryer clear to prevent obstruction of combustion and ventilation airflow

as well as for service and maintenance and adhere to the following:

1. Do not connect this fryer to an exhaust duct.

2. Correct installation and adjustment will ensure adequate airflow to the fryer system.

3. A commercial, heavy-duty fryer’s combustion wastes must be vented to the outside of the
building. A deep-fat fryer must be installed under a powered exhaust hood, or an exhaust
fan must be provided in the wall above the unit, as exhaust gas temperatures are
approximately 800-1000°F (427-538°C). Check air movement during installation. Strong
exhaust fans in the exhaust hood or in the overall air conditioning system can produce
slight air drafts in the room, which can cause erratic burner flames and/or improper fryer
operation.

4. Do not place the fryer’s flue outlet directly into the plenum of the hood, as it will affect the
gas combustion of the fryer.

5. Never use the interior of the fryer cabinet for storage or store items on shelving over or
behind the fryer. Exhaust temperatures can exceed 800°F (427ºC) and may damage or
melt items stored in or near the fryer.

6. Adequate distance must be maintained from the flue outlet of the fryer(s) to the lower edge
of the filter bank. Per NFPA Standards No. 96, a minimum of 18-inches (45-cm) should be
maintained between the flue(s) and the lower edge of the exhaust hood filter.

7. Filters and drip troughs should be part of any industrial hood, but consult local codes before
constructing and installing any hood. The duct system, the exhaust hood and the filter
bank must be cleaned on a regular basis and kept free of grease.

B. 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
gas connections. If a flexible gas hose is used, a restraining cable must be connected at all
times when the fryer is in use. The restraining cable and installation instructions are
packed with the flexible hose in the accessories box that was shipped with your unit.

2-4

CHAPTER 2: IMPORTANT INFORMATION

2.6 Air Supply and Ventilation (cont.)

2. Single unit fryers must be stabilized by installing restraining chains on appliances
equipped with casters or anchor straps on appliances equipped with legs. Follow
instructions shipped with the casters/legs to properly install the chains or straps.

DANGER

Do not attach an apron drain board to a single unit. The appliance may become

unstable, tip over, and cause injury. The appliance area must be free and clear of

combustible material at all times.

2.7 Equipment Installed at High Altitudes

A. The fryer input rating [BTU/hr (kW/hr)] is for elevations up to 2,000 feet (610-m). For

elevations above 2,000 feet (610-m), the rating should be reduced four percent for each
additional 1,000 feet (305-m) above sea level.

B. The correct orifices are installed at the factory if operating altitude is known at time of the

customer’s order.

2.8 Conversion of Units

Pressure:

1 mbar = 10.2 mm water column (mm W.C.) = 0.4 Inch WC
20 mbar = 204 mm W.C. = 8 Inch W.C.

4. Insert hex head screws with lock washers [1/4-20 threads by ¾" (19-mm) long] through bolt
holes of leg mounting plates and mount to the front channel. Mount rigid casters to the rear
channel following the same procedure. Locknuts have been attached to the topside of the
base mounting plates at the factory to capture hex head screws as they are screwed in.

5. Tighten the bolts to 50 inch-lbs. (5.65 joules) minimum torque.

WARNING

For caster retrofit, the unit must be at room temperature and drained of shortening

before installing the casters.

3.3 Leveling the Fryer

A. Place a carpenter’s spirit level across the top of the fryer and level the unit front-to-back. If the

fryer is off level side to side, a platform or other surface adjustment is needed; there is no side to
side level adjustments on a fryer equipped with caster/leg combinations (If a fryer is equipped
with legs only, side to side level adjustments can be made. If a fryer is equipped with casters
only, no level adjustments to the fryer can be made.). If the fryer is not level, the unit may not
function efficiently, the oil may not drain properly for filtering and in a multi-fryer battery, it
may not match adjacent units.

Legs (Only)

1. Adjust leg height with an adjustable or 1-1/16-inch (27-mm) open-end wrench by turning
the hex bullet on the bottom of the leg.

3.3 Leveling the Fryer (cont.)

ANSI Z83.11a-(Latest Edition) requires a fryer be restrained to prevent tipping when installed
in order to avoid the splashing of hot liquid. The means of restraint may be the manner of
installation, such as connection to battery of appliances or installing the fryer in an alcove, or
by separate means, such as adequate ties (chains, straps, etc.). A bracket has been provided on

the fryer back panel for this purpose.

NOTE: The installation must be inspected after it is complete to ensure it meets the intent of
these instructions. The on-site supervisor and/or operator(s) should be informed that the
appliance is installed with restraints. If restraints are removed to move fryer (cleaning
beneath and behind, relocation, etc.), ensure that they are re-installed when fryer is returned
to its permanently installed position.

CHAPTER 3: INSTALLATION INSTRUCTIONS

3.4 Gas Connections (cont.)

Supply Line Specifications

The gas supply lines must be sized as indicated in the chart below, based on the total number of
fryers connected to the main gas supply.

Gas Types Number of Fryers

1 2 to 3 4 or more (*)
Natural Gas 3/4" (22 mm) 1" (28 mm) 1 1/4" (35 mm)
Propane Gas 1/2" (15 mm) 3/4" (22 mm) 1" (28 mm)
(*) When exceeding 18 feet (6 meters) for a configuration of more than four fryers, it is necessary

to provide a 1 1/4" (35 mm) rigid gas connection.

Recommended Gas Supply Line Sizes

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.

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.

KSCF18G COOL ZONE SERIES GAS FRYERS
CHAPTER 3: INSTALLATION INSTRUCTIONS

3.4 Gas Connections (cont.)

Rigid Connections

Check any installer-supplied intake pipe(s) visually and clean metal particles or other foreign matter
from the threads before installing into a service line. If the intake pipes are not clear of all foreign
matter, the orifices will clog when gas pressure is applied. When using thread compound on gas
piping, use very small amounts and only on male threads. Use a pipe thread compound that is not
affected by the chemical action of LP gases. DO NOT apply thread compound to the first two pipe
threads—doing so will cause clogging of the burner orifices and control valve.

Manual shut-off valve

This gas service supplier-installed valve must be installed in the gas service line ahead of the fryers
in the gas stream and in a position where it can be reached quickly in the event of an emergency.

Regulating Gas Pressure

The fryer and shut-off valve must be disconnected from the gas supply during any pressure testing of
the system.

External gas regulators are not normally required on this fryer. A safety control valve protects the
fryer against pressure fluctuations. If the incoming pressure is in excess of ½" PSI (3.45 kPa/35
mbar), a step-down regulator will be required.

DANGER

When pressure-testing incoming gas supply lines, disconnect the fryer from the gas

line if the test pressure is 3,45 kPa (½" PSI, 14" W.C.) or greater to avoid damage to

the fryer’s gas piping and gas valve(s).

The fryer and its individual shut-off valve must be disconnected from the gas supply piping system
during any pressure testing of the gas supply system, especially if the test pressures are in excess of
½" PSI (3.45 kPa/35 mbar).

A. Manifold Pressure: Your local service technician should check the manifold pressure with a

manometer.

1. Check the rating plate for manifold gas pressures. Natural gas units normally require 4"
WC, and propane units normally require 11" WC gas pressure.

2. Confirm that the arrow forged into the bottom of the regulator body, which indicates gas
flow direction, is pointed downstream towards the fryers. The air vent cap is also part of the
regulator and should not be removed.

3.11 Initial Cleaning Before Startup

New units are wiped clean with solvents at the factory to remove any visible signs of dirt, oil, grease,
etc., remaining from the manufacturing process, then coated lightly with oil. Wash thoroughly with
hot, soapy water to remove any film residue and dust or debris before food preparation, then rinse
out and wipe dry. Wash also any accessories shipped with the unit. Close the drain-valve
completely and remove the crumb screen. Ensure the screws securing the temperature probe to the
bracket between heating tubes are tight.

WARNING

All droplets of water must be removed from the frypot before filling with shortening.

Failure to do so will cause splattering of hot shortening and could cause injury to the

operator.

3.12 Final Preparation

1. The KSCF18G frypot shortening capacity is approximately 40.5Kg (90 pounds).

2. Ensure fryer power switches are "OFF".

3. Ensure the float switch is in "up" position if using solid shortening.

4. Liquid shortening (cooking oil): Fill the fryer to the bottom OIL LEVEL line scribed into the

back of the frypot. Replace the basket support screen.

WARNING

Never operate fryer without enough oil/shortening or water in the frypot to cover the

heating tubes.

WARNING

NEVER set a complete block of solid shortening on top of heating tubes. To do so

will damage the frypot and increase the potential for flash-point shortening

temperatures and subsequent fire.

5. Solid shortening: Either pre-melt solid shortening on another appliance first or cut into small
pieces and pack tightly into the cool zone (bottom) of the frypot. Take care not to disturb
the temperature probe or high-limit when packing shortening into frypot. If solid shortening
is packed into the frypot, ensure the float switch is in the "up" position.

3-15

KSCF18G COOL ZONE SERIES GAS FRYERS
CHAPTER 3: INSTALLATION INSTRUCTIONS

3.12 Final Preparation (cont.)

Note: If the float switch is blocked in "down position" with solid shortening, the fryer will not

operate. Always ensure that the float switch is in the "up" position when packing solid
shortening into frypot.

6. KFC-1 Cooking Computer:
Turn computer "ON" (this
turns the fryer on also­electronic ignition equipped
fryers only). The computer
will cycle the burners on and
off (melt cycle). This is
indicated by heat icons located
on either side of the KFC-1
product buttons, which will
cycle on and off. The

computer will display "LOw"

until the shortening reaches
255°F (124°C).

At 255° F (124°C), the fryer goes into continuous heat mode. The computer will display actual
shortening/oil temperature until setpoint is reached. At setpoint temperature, the computer will

display "drop".

7. After shortening reaches the setpoint temperature, let the burners cycle at least four times,
then insert a good thermometer or pyrometer near the temperature sensing probe
approximately 7.5-mm (3-inches) deep into the shortening. When the burners just cycle on
after the fourth time, the thermometer should read within ±5°F (±2°C) of the computer
temperature setting.

8. When the frypot is filled and the shortening melted, replace the basket-support screen over
the heating tubes.

• 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 mounting hardware and probe guard 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 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.

Built-in Filtration:

• 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.

CHAPTER 6: PREVENTATIVE MAINTENANCE

6.4 Periodic/ Annual (cont.)

• 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 refill in no more
than 2 minutes and 30 seconds.

To ensure good fryer health and a safe environment, the fryer should be checked and adjusted
periodically by qualified service personnel as part of a regular kitchen maintenance program.

6.5 Stainless Steel

All stainless steel fryer outer parts should be wiped regularly with hot, soapy water during the day
and with a liquid cleaner designed for this material at the end of each day.

Do not use steel wool, abrasive cloths, cleansers or powders!

Do not use
almost impossible to remove.

If it is necessary to scrape the stainless steel to remove any encrusted materials, soak the area first to
loosen the material, then use a wood or nylon scraper only.

a metal knife, spatula or any other metal tool to scrape stainless steel! Scratches are

CHAPTER 7: TROUBLESHOOTING

7.1 Introduction

This section provides an easy reference guide to some of the common problems that may occur
during the operation of this equipment. The troubleshooting guides that follow are intended to help
correct, or at least accurately diagnose, problems with this equipment. Although this chapter covers
the most common problems reported, you may encounter problems, which are not addressed. In
such instances, the Frymaster/Dean Technical Service 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. Never overlook the obvious – anyone can forget
to plug in a cord or fail to close a valve completely. Most importantly, always try to establish a clear
idea of why a problem has occurred. Part of any 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, too. If a fuse continues to blow, find out why. Always keep in mind that the
failure of a small component may often be indicative of potential failure or incorrect functioning of a
more important component or system.

Before calling a service agent or the Frymaster/Dean HOTLINE [phone]):

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

• Verify that frypot drain valves are fully closed.

• Verify that gas line is properly connected.

DANGER

Never attempt to move a fryer containing hot cooking oil/shortening or to transfer

hot cooking oil/shortening from one container to another.

DANGER

Use extreme care when testing electrical circuits. Live circuits will be exposed.

WARNING

Inspection, testing, and repair of electrical components should be performed only by

qualified service personnel. The equipment should be unplugged when servicing,

except when electrical tests are required.

DANGER

NEVER use open flame to melt solidified shortening-blockage in the filtration

system. Open flame increases the chance for extreme fire hazard and operator

injury.
