DEEP FAT FRYER INSTRUCTIONS

INSTALLATION INSTRUCTIONS

Check the data plate located inside the drain valve door for fryer electrical rating. Check

power source to insure that it is the correct voltage and current rating.

Electrical service may be made through a standard 1¼ inch conduit. A hole is provided

through the rear panel. A knockout is also provided in the bottom rear of the fryer, so

that power may be brought in from below the unit. Plug the hole on the rear panel when

using bottom power entry. Check the National Electrical Code for fuse for circuit breaker

requirements.

A two pole terminal block is provided behind the rear access cover for connection to an

external fire control system if required. A jumper is provided across these terminals

when the fryer leaves the factory. The jumper on this terminal block is in series with the

contactor coil circuits. If connection to a fire control system is required, remove this

jumper and supply a relay contact closure to maintain this closed circuit. If the fire

control system does not have this type output, a separate relay must be provided to

interface the system. Use copper wire only.

WARNING:

DO NOT APPLY POWER TO THESE TERMINALS. EXTERNAL

POWER WILL DAMAGE THE FRYER CONTROL CIRCUITRY.

Connect a ground lead to the green ground lug provided in the rear compartment.

These fryers are to be connected to three-phase power as follows:

Connect wires 1 and 4 to line 1, wires 2 and 5 to line 2, and wires 3 and 6 to line 3.

Please contact the factory for single-phase connections.

CAUTION:

DO NOT CONNECT TO A CIRCUIT OPERATING AT MORE THAN

150 VOLTS TO GROUND.

OPERATING INSTRUCTIONS

Fill the fryer with cooking oil. There are two fill marks on the sides of the kettle. The oil

level should be maintained between the upper and lower marks.

The power switch on the control box at the front of the fryer energizes the control

circuits. When this switch is on, the “power” pilot lamp will be illuminated.

Turn the temperature selector dial on the thermostat to the desired temperature setting.

This control is located above the elements at the rear of the kettle. The “heat” pilot lamp

will illuminate indicating power is applied to the heating elements.

The lamp marked “overtemp” will illuminate if the oil reaches an over temperature

condition. The over temperature thermostat shuts off the fryer before the oil reaches a

dangerously high temperature.

The elements may be raised and locked in the up position. The latch is located on the rear

top surface of the fryer and may be activated by lifting the handle at either side of the

fryer.

A drain valve is provided at the left front of the fryer. Always turn the fryer power off

before lifting the elements of draining the oil from the fryer.

On those models with automatic bracket lifts, the cooking times may be set from 1 to 16

minutes with the timer control dials.

Pressing down on the spring return elevator switches will lower the basket lifts. At the

end of the time set on the dial the lift will return to the up position. The time cycle may

be canceled at any time by pressing the elevator switch to the up position.

MAINTENANCE INSTRUCTIONS

Maintenance of the C-28 series fryers is simple and straightforward. Temperature control

is provided by a bulb thermostat located near the right heating element as the fryer is

viewed from the front. This thermostat controls the No. 1 contactor. The over

temperature thermostat located next to the left heating element provides protection in case

of malfunction of the temperature control. It will open both contactors removing all

power from the heating elements.

A circuit diagram of the fryer is located on the rear cover of the control box. This box

may be removed by removing the 4 sheet metal screws located beneath the box on the left

and right sides of the fryer lower front.

In the event the fryer is built into a location, all maintenance may be done from the front

by removing the oil pot to gain access to the contactors. To remove the pot, the control

box must be removed as above. Also, remove the small section of sheet metal baffle

held on by 2 sheet metal screws, located just above the drain valve. The front of the pot

may now be lifted up and moved forward until the rear of the pot will rotate up and out.

The baffles behind the pot may be removed by taking out 4 screws. This exposes the

contactors.

The thermostats are located in the head assembly. The bottom cover of the head is

removable for access to the elements, thermostats and pilot lamps.

In 480-volt units a transformer is provided in the rear of the fryer to step 480 volts to 240

volts for operation of the control circuit.
