1.1 Functional Description (cont.)
CONTROL OPTIONS
MJCF Series gas fryers may be equipped with thermostat controllers or Computer Magic III.5
computers. KJ3FC variants are equipped with user-supplied or KFC-1 computers.
MJCF fryers equipped with thermostat controls are turned on and off with the gas valve control knob
(an On/Off switch is optional). The temperature is set by means of a knob connected directly to the
frypot-mounted thermostat. MJCFE models come equipped with a rocker switch to turn the fryer on
and off. Units equipped with thermostat controllers have no interface board.
MJCFE Series with Melt-Cycle option: When the melt cycle switch is placed in the ON position, the
fryer stays in the melt cycle mode until the switch is manually placed in the OFF position, even if the
frypot is at setpoint temperature.
Fryers equipped with computers have an interface board located in the component shield behind the
control panel.
INTERFACE BOARDS
The interface board provides the link between the computer and the fryer’s components without
requiring excessive wiring, and allows the computer to execute commands from one central point.
Depending upon the configuration of the fryer, any of three boards may be used. Regardless of the
particular board installed when the fryer was built, P/N 806-3548 is the universal replacement
part (not applicable to user-supplied computers).
