Supplies 120VAC to pump motor when filter relay is energized.
Supplies 120VAC to pump motor through filter relay contacts (N.O.) when
24VAC coil is energized. Filter power switch must be ON and the filter valve
switch or discard valve switch must be CLOSED (valve handle extended).
Supplies 24VAC to the oil filter control circuit and fryer power switch.
Transformer is energized when supply power is connected to fryer.
Supplies 12VAC to the computer power supply board. Transformer is
energized when fryer power switch is turned ON. Computer control models
only.
Operates the "pump" to circulate oil through the filtering system.
Energizes the filter relay coil to supply power to the pump motor through
filter relay contacts (N.O.) when switch is CLOSED (valve handle extended).
When oil filtering is complete, close the manual drain valve to the fryer and
allow the vat to refill. Retract the filter handle when all filtered oil is returned.
Energizes the filter relay coil to supply power to the pump motor through
filter relay contacts (N.O.) when switch is CLOSED (valve handle extended).
This allows the oil to be discarded through the discard hose into a separate
container. When filter tank is empty, retract the handle to return the discard
switch to normal operating position.
Energizes relay coil R1 and supplies power to fryer control circuit through
relay R1-1 contacts (N.O.). The switch positions are: momentary ON,
momentary OFF with a center NEUTRAL (starting) position. Solid state
controls only.
Circuit 1 on the switch is the normally CLOSED (N.C.) side. Press power
OFF to momentarily OPEN switch contacts and turn the fryer OFF.
Circuit 2 on the switch is the normally OPEN (N.O.) side. Press power ON to
momentarily CLOSE switch contacts and turn the fryer ON.
Supplies power to fryer control circuit and basket lift circuit (if installed)
through relay R1-1 contacts (N.O.) when 24VAC coil is energized. The relay
remains energized through R1-2 contacts (N.C.) and fryer power switch
contacts until power switch is turned OFF. Full vat and split vat fryers, solid
state controls only.
Supplies power to fryer control circuit and basket lift circuit (if installed)
through relay R2-1 contacts (N.O.) when 24VAC coil is energized. The relay
remains energized through R2-2 contacts (N.C.) and fryer power switch
contacts until power switch is turned OFF. Split vat fryers with solid state
controls only.
