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.

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

WARNING
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

DANGER

No structural material on this appliance should be altered or removed to accommo­date placement of the appliance 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.

This equipment must be installed with a 6” (150mm) 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” (600mm) clearance should be provided at the front of the
unit.

2-1

One of the most important considerations of efficient operation is ventilation. Make sure the equip­ment 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 equipment flue opening must not be placed close to the intake of the exhaust fan, and the flue
must never be extended in a “chimney” fashion. An extended flue will change the combustion char­acteristics of the equipment, causing longer recovery times. It also frequently causes delayed igni­tion. To provide the airflow necessary for good combustion and burner operation, the areas sur­rounding the front, sides, and rear of the unit must be kept clear and unobstructed.

This equipment must be installed in an area with an adequate air supply and adequate ventilation.
For U.S installations, information on construction and installation of ventilating hoods can be found
in NFPA Standard 96. This document can be ordered from the National Fire Protection Association,
Battery March Park, Quincy, MA 02269. For installations in countries other than the U.S., the ap­propriate regulating authority should be contacted for information related to hood construction and
installation.

DANGER
Do not attach an apron drain to a single rethermalizer. The rethermalizer may
become unstable, tip over, and cause injury to personnel.

NATIONAL CODE REQUIREMENTS

This equipment is to be installed in compliance with the Basic Plumbing Code of the Building Offi­cials and Code Administrators International, Inc. (BOCA) and the Food Service Sanitation Manual
of the U.S. Food and Drug Administration.

This equipment is manufactured to use the type of gas specified on the rating plate attached to the
door. Connect equipment stamped “NAT” only to natural gas and that stamped “PRO” only to LP
(Propane) gas.

Installation shall be made with a gas connector that complies with national and local codes. Quick
disconnect devices, if used, shall likewise comply with national and local codes.

ELECTRICAL GROUNDING REQUIREMENTS

DANGER
This appliance is equipped with a three-prong (grounding) plug for your protection
against electrical shock, and must be plugged directly into a properly grounded
three-prong receptacle. Do not cut, remove, or otherwise bypass the grounding
prong on this plug!

DANGER

local codes. A wiring diagram is located on the inside of the door. In the United States and Canada,
the electrical supply must be 120VAC, 60 Hz. In other countries, refer to the rating plate on the
inside of the door for proper voltages.

FCC COMPLIANCE

The user is cautioned that any changes or modifications to Frymaster computers not expressly ap­proved by the party responsible for compliance could void the user’s authority to operate the equip­ment. Frymaster computers have been tested and found to comply with the limits for a Class A digi­tal device, pursuant to Part 15 of the FCC rules. While these devices are verified as Class A devices,
they have been shown to meet the Class B limits. These limits are designed to provide reasonable
protection against harmful interference when the equipment is operated in a commercial environ­ment. This equipment generates, uses, and can radiate radio frequency energy and, if not installed
and used in accordance with the instruction manual, may cause harmful interference to radio com­munications. Operation of the equipment in a residential area is likely to cause harmful interference
in which case the user will be required to correct the interference at his own expense. If necessary,
the user should consult the dealer or an experienced radio and television technician for additional
suggestions.

The user may find the booklet “How to Identify and Resolve Radio-TV Interference Problems” help­ful. It is prepared by the Federal Communications Commission and is available from the U.S. Gov­ernment Printing Office, Washington, DC 20402, Stock No. 004-000-00345-4.

2.2 Caster/Leg Installation

Depending upon the specific configuration ordered, your unit may have been shipped without in­stalled casters or legs. If casters or legs are installed, you may skip this section and proceed to Sec­tion 2.3, Pre-Connection Preparations.

If your unit requires the installation of casters/legs, install them in accordance with the in­structions included in your accessory package.

2.3 Pre-Connection Preparations

DANGER
Do not connect this equipment to the gas supply before completing each step in this
section.

After the unit has been positioned in the area where it will be used, ensure the following has been
accomplished before connecting the unit to the gas supply:

1. Adequate means must be provided to limit the movement of this equipment without depending

upon the gas line connections. If a flexible gas hose is used, a restraining cable must be
connected at all times when the equipment 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.

2-3

2. The rethermalizer must be stabilized by installing restraining chains on units equipped with
casters or anchor straps on units equipped with legs. Follow the instructions shipped with the
casters/legs to properly install the chains or straps.

3. Level rethermalizers equipped with legs by screwing out the legs approximately 1 inch then
adjusting them so that the rethermalizer is level.

4. For rethermalizers equipped with casters, there are no built-in leveling devices. The floor where
the rethermalizer is to be installed must be level.

DANGER
Do not attach an apron drain board to this 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.

5. Connect the water hose to the fitting at the rear of the unit.

NOTE 1: The hose comes with a quick-disconnect coupling. The quick disconnect may be at­tached to the rethermalizer or to the water supply line, or it may be left off entirely, whichever
you prefer. Whichever of the options is chosen, Teflon thread-seal tape or Loctite™ PST56765
or equivalent thread sealer must be used when installing the fittings.

NOTE 2: Either hot or cold water may be connected to the unit. Connecting to hot water will
minimize the amount of time required to bring the unit to boil when filling with fresh water.
However, on FBCR18 units, connecting to hot water will lower the efficiency of the chill fea­ture.

NOTE 3: In order for the water level sensors to work properly, a certain amount of mineral con­tent in necessary in the water. For that reason, purified, deionized, or highly filtered water
should not be used.

4. Connect the desired drain plumbing to the 1¼” drain valve.

5. Test the equipment electrical system by plugging the power cord into a grounded 120VAC outlet

°

and pressing the computer’s ON/OFF button.

-Lo or cycl should appear in the display.

6. Turn the computer off. Verify that the display is blank.

7. Verify that the minimum and maximum incoming gas pressures for the type of gas to be used are

in accordance with the accompanying table.

2.4 Connecting to the Gas Supply

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 appliance 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 appliance’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 cookpot. Always ensure that water
is in the cookpot before firing the unit.

GAS CONNECTIONS AND PIPE SIZES

The size of the gas supply pipe is very important. If the pipe is too small, the gas pressure at the
burner manifold will be low. This will cause slow recovery and delayed ignition. The incoming gas
supply line should be a minimum of 1½ inches (38mm) ID.

When configured for natural gas, this equipment requires a standard gas pipe size of ¾ inch (19mm)
ID for connections within 20 feet (6m) of the supply line, provided no more than 4 fittings or elbows
are used in the run. For a pipe run over 20 feet (6m), increase the pipe size to 1 inch (25.4mm). For
use with LP (Propane) gas, the next smaller pipe size may be used.

IF IN DOUBT ABOUT THE PIPE SIZE TO BE USED, CONSULT YOUR LOCAL GAS
COMPANY.

1. Connect the equipment to the gas supply line.

When making connections, apply a small amount of Loctitite® PST 56765 or equivalent thread
compound to the male threads only. DO NOT apply the compound to the first two threads. This
will prevent clogging of the burner orifices and control valve.

2-5

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

3. Close the drain valve and fill the cookpot with water and boil-out solution to the overflow. Light
the burners and perform the boil-out procedures that are described in the “Start-Up Procedure”
and “Boiling Out the Cookpot” sections in Chapter 3 of this manual.

4. It is suggested that the burner manifold pressure be checked at this time by the local gas com­pany or an authorized service agent. Refer to “Check Burner Manifold Pressure” in Chapter 4 of
this manual for the proper procedure.

2.5 Converting to Another Gas Type

This equipment is configured at the factory for either natural gas or LP (Propane) gas.

If you desire to switch from one type of gas to the other, a gas conversion kit must be installed by a
Factory Authorized Service Center technician.

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 kit 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 1.6 of this manual.

WARNING
The on-site supervisor is responsible for ensuring that operators are made aware of
the inherent hazards of operating a gas-fired heated water system, particularly the
aspects of draining and cleaning procedures.

Mechanically, the FBCR18 and FBKR18 rethermalizers are virtually identical. The FBKR18 units
have a manual fill switch in addition to the AutoFill feature.

The primary difference between the two rethermalizers is the controller. Both units use modified
Computer Magic III (CM III) computers. Although the computers are very similar in appearance
(and to standard CM III computers), they are not interchangeable.

3.2 FBCR18 Series Computer

This computer has 12 programmable product buttons and a “chill” switch. The chill switch shuts
off the burners, but does not turn off the computer. This allows unused product to be quickly
cooled before being returned to a refrigerator or freezer.

The product buttons are multi-functional. In the programming mode, each button can be
programmed for a distinct rethermalizing time. In the rethermalizing mode, pressing a button
initiates a specific timed countdown.

3.3 FBKR18 Series Computer

This computer has 10 programmable product buttons, a Simmer Mode switch, and a Boil Mode
switch. The computer also has two Power switches; press either switch to turn the unit on and off.

The product buttons are multi-functional. In the programming mode, each button can be
programmed for a distinct rethermalizing time. In the rethermalizing mode, pressing a button
initiates a timed countdown of a specific product.

Pressing the Boil Mode (L) switch overrides the programmed setpoint and the cookpot temperature
rises to boiling at 212°F (100°C). When the unit is in boil mode, boiL appears in both LED
displays. The unit remains in boil mode until the Simmer Mode switch is pressed or the unit is
turned off.

Pressing the Simmer Mode (R) switch causes the cookpot temperature to be maintained at the
programmed setpoint. If the cookpot temperature is above the setpoint, °-HI is displayed in both
LED widows. If the cookpot temperature is below the setpoint, °-Lo is displayed. Four dashes

(- - - -) are displayed if the temperature is within 11°F (6°C) of setpoint.

CAUTION

It is recommended that the simmer setpoint and the heat/stir times for all 10
products be programmed before the unit is first used in a rethermalizing cycle.

The simmer setpoint and product rethermalizing times are programmed at the factory. These are
test settings not default settings. You must program the unit for your own particular products.
Program the setpoint

and all product rethermalizing times as follows:

1. Turn the computer on by pressing the Power

switch.

2. Enter the programming mode by pressing the Program Mode

switch. CodE appears in the
