System Overview The fryers and filter systems covered in this manual have been specially tailored by Pitco Frialator, Inc. for use in KFC stores. With proper installation, operation, and maintenance, you will recieve many years of dependable operation.

This manual covers the models 7-2WKS, 7-3 WKS, and 7-4 WKS multivat gas fryers, as well as the 7-3WKS-UFM and 7-4WKS

UFM models. The WKS units require a portable filter unit, and the WKS-UFM models incorporate the Spacefighter built-in filter system. UFM filter systems make filtration quick, easy and possible during peak periods, eliminating the traffic obstruction and

safety hazards of conventional filtration procedures.

All of the fryers are equipped with 16-gauge stainless steel tanks. In addition, all of the fryers have electronic ignition systems,

eliminating the need to light the pilot with a match. Another feature common to all of the fryers is the float switch, which cuts off power to the heating system should the shortening be inadvertantly drained, preventing scorching of the shortening and the tank itself.

These fryers are designed to work with the new generation of KFC proprietary FAST computer controllers. One computer can control up to two fryers simultaneously. These computers are purchased separately; instructions for installing the computer controller

to the fryer are included in this manual.

Installation Procedure It is required that you have a qualified service technician perform the installation of the fryer; please supply the technician with this manual and have him/her follow the procedures given below.

� Bring the fryer to the area in which it will be connected to utilities and where it will be operating

� Connect gas piping to the fryer; refer to Specifications Table and the Fuel Gas System section of this manual for proper pipe sizes

� lf you are going to install a flexible hose with a quick-disconnect, be sure that the disconnect has adequate flow capacity for the particular model fryer

g NOTE: If you are installing a flexible hose, you must install a fryer restraining loop, shorter than the gas line itself—refer to the Fuel Gas System section of this manual for further information

� Make sure you have the heat deflector(s) (1/fryer) provided by Pitco Frialator; clip onto the fryer prior to positioning the unit under the ventilation system (refer to Figure L-1)

� Using a large, adjustable wrench or pliers, turn the large hex on the caster base to raise or lower each caster and level the fryer.

Installation 8

Figure L-1: Installing Fryer Accessories.

Installation 9

Gas Piping Capacity

�In order to achieve the degree of performance for which the fryer is designed, a well-planned and properly-sized gas supply system is essential

�Piping size should be appropriate to supply gas sufficient to the maximum demand of all appliances on the line without loss of pressure at any of the equipment

�Other criteria in determining gas piping size are the total BTU requirements of the equipment served and the length of piping from the meter to the appliances

�The installation must conform with local codes or, in the absence of local codes, with the National Fuel Gas Code, ANSI Z223.1-1988

�Your local gas company should consult the National Fuel Gas Code—Appendix C, Table C-4 (for natural gas) and Table C-16 (for propane)—for proper sizing and installation of gas piping

�Also refer to the section of this manual covering Fuel/Gas Installation.

Gas Leak Testing g NOTE: NEVER use an open flame to test for gas leaks

�Before operating the fryer, test all fuel gas connections for leaks, using a solution of soap and water

�If the gas-supply system is going to be tested at a pressure GREATER THAN 1/2 psig (3.45kPa), the fryer and its individual shut-off valve must be disconnected from the supply line

�If the gas-supply system is going to be tested at a pressure EQUAL TO OR LESS THAN 1/2 psig, the fryer's manual shut-off valve must be closed during testing.

Electrical/Grounding System

�North American electrical requirements: 120 VAC 60 Hz, 0.5 amp per fryer, 7 amps per filter system

�International electrical requirements: 220 (or 240) VAC 50 Hz, 0.5 amp per fryer, 4.0 amps per filter system

�The power cord with the straight-blade plug provides power for the filter module. The filter module plugs into a receptacle located inside the fryer cabinet

�The third prong on the fryer plug grounds the system for your protection against electrical shock—insert the plug directly into a properly-grounded three-prong receptacle

gNOTE: NEVER remove the third, or grounding, prong from the plug

�The fryer must be electrically grounded in accordance with local codes; if local codes do not apply, comply with National Electrical Code, ANSI/NFPA 70-1990.

Installation 10

Fuel/Gas System

�All gas service must comply with local codes; if local codes do not apply, install the fuel gas service in accordance with the National Fuel Gas Code ANSI 7233.1-1988

�In Canada install the fryer in accordance with CAN1-B149.1 and CAN1-B149.2 and/or local codes

�Contact the local gas company to determine the correct size for the gas supply line; the fryer will not operate properly if the gas line is too small

�When making the gas supply connections, use a pipe joint compound resistant to liquified petroleum gases

�Be certain that all gas-supply piping to the fryer allows for the proper minimum clearance at the side, rear and floor level—refer to the data plate inside the front door

�Level the fryer in accordance with the instructions provided in this manual

�Field-attached piping assemblies must not interfere with filter module travel or, if equippped with casters, the caster-swivel radius

gNOTE: ALWAYS provide gas-supply connection lines that have been sized to be equivalent to the supply connection on the fryer

g NOTE: NEVER use adaptors to make a smaller line fit, as an inadequate line size may not allow sufficient gas volume for proper burner operation, resulting in poor fryer performance

�Low gas volume/pressure can also cause "lazy" flames, which do not travel through the tank properly; this can cause high temperatures on tank areas and create carbon monoxide

�The fryer is equipped to work with one specific type of fuel gas—this information is given on the data plate inside the fryer door

gNOTE: NEVER supply the fryer with any kind of fuel other than the type indicated

�Flexible hose quick-disconnect installation shall be made with a connector which complies with the "Standard for Connectors for Moveable Gas Appliances", ANSI Z21.69-1987, and a quick-disconnect device which complies with the "Standard for Quick-Disconnect Devices for Use with Gas Fuel", ANSI Z21.41-1978 and Addenda Z21.41a-1981 and Z21.41b-1983

�The restraining device must be shorter than the gas connector, to prevent strain on the gas connector

�A fryer restraining loop must be provided to limit the movement of the fryer without depending on the connector and the quick-disconnect device, or its associated piping-to limit the fryer's movement

�It is recommended that the attachment for the fryer restraining loop be installed in the rear center of the fryer cabinet (between the two tanks) at approximately 30" above floor level

�Use caution when drilling and installing attachment

�Do not locate in such a manner that the mounting screws will perforate either of the fryer flues.

Fire Detection/Extinction System

gNOTE: We STRONGLY ADVISE you to install an approved fire detection and extinguishing system.

�Exhaust temperatures from the fryer may run as high as 1200°F; therefore, select a fire-extinguishing system and a sensing device that activates your system with this in mind, in order to reduce the possibility of false alarm.

£Unscrew the limit bulb clamp screws from the heat tube inside the tank; remove the screws and bulb clamp

£Straighten the capillary tubing attached to the bulb

£Locate the connector fitting inside the cabinet at the bottom of the tank; unscrew the small hex nut in the connector fitting

£Unscrew the large hex nut, and withdraw the capillary and the sensing bulb from the tank

£Remove two screws holding the corner control box to the cabinet front

£Remove two screws holding the limit control to the corner box

£Remove the two screws to remove the wires from the limit control

£Remove the limit control from the fryer

£Unpack the new limit control; carefully unroll the capillary tubing and straighten it out

£Reverse the procedure to install the new control as follows:1

g NOTE: DO NOT BEND, KINK, OR TWIST THE CAPILLARY TUBING SHARPLY; THIS WILL DESTROY THE LIMIT CONTROL

£Apply pipe joint compound to the pipe threads on the large connector fitting nut, to prevent oil leaks

£Do not use pipe joint compound on the threads of the small nut; this is a ferrule fitting

£Prior to tightening the small connector fitting nut, adjust to obtain proper capillary length inside the fry tank

£Ensure that the limit control bulb is mounted properly in the bulb clamp; the limit control bulb mounts furthest from the weld holding the clamp pad to the heat tube—the computer temperature sensor mounts closest to the heat tube.
