ELECTRICAL OPERATION

COMPONENT FUNCTION

Control Box
Assembly . . . . . . . . . . . . .

Contains components used to set and control temperature.

Start Switch . . . . . . . . . .

Engages contactors to supply power to heating elements.

Power Switch . . . . . . . . .

Supplies power to control circuit for fryer operation.

Melt Switch . . . . . . . . . . .

Selects type of shortening being used (liquid/ solid).

Start-On Indicator
Light . . . . . . . . . . . . . . . . . .

Green LED located on control box assembly. Indicates start switch has been pressed.

Heating Indicator
Light . . . . . . . . . . . . . . . . . .

Yellow LED located on control box assembly. Indicates heating elements are on or off.
LED cycles on and off.

Temperature Knob . . . .

Used to set the desired operational temperature.

Chassis ON Indicator
Light . . . . . . . . . . . . . . . . . .

Green lamp located on right-side of chassis. Indicates power switch has been pressed.

Chassis HEAT
indicator Light . . . . . . . .

Yellow lamp located on right-side of chassis. Indicates if heating elements are on or off.
Lamp will cycle on and off.

Drain Valve . . . . . . . . . . .

Used to drain tank.

Drain Valve Switch . . .

Magnetic reed switch mounted on drain valve. 24VAC power to temperature controller
board passes through switch. When drain valve is open, 24VAC power is removed from
temperature controller board. This prevents heating elements from being energized when
valve is open.

Heating Element . . . . . .

Used to heat shortening. Cycles on and off as to maintain desired temperature.

High Temperature
Limit Switch . . . . . . . . . .

Used to limit operational temperature. Opens and removes power if shortening
temperature exceeds 460°F. It has a pushbutton switch that must be pushed to reset it.
The switch cannot be reset until shortening temperature drops below 415°F.

It is wired in series with tilt switch and removes power from power contactor coil when
open.

Tilt Switch . . . . . . . . . . . .

Magnetic switch mounted underneath element head assembly. Monitors heating
elements position (lowered [closed] or raised [open]).It is wired in series with high
temperature switch and removes power from power contactor coil when open.

Temperature
Sensor . . . . . . . . . . . . . . . .

Monitors shortening temperature.

Fuse . . . . . . . . . . . . . . . . . .

Protects fryer electrical circuits from damage.

Heat Relay . . . . . . . . . . . .

Supplies power to heat contactor coil.

Contactor . . . . . . . . . . . . .

Controls power to heating elements.

Transformer . . . . . . . . . .

Provides 24VAC operational power to control box assembly / control circuit.

Circuit Breaker* . . . . . .

Protects fryer electrical circuits from damage.

Terminal Block . . . . . . .

Connects factility power to unit.
