Supply Connection
1. All units are provided with two terminal blocks for field wire connections on the rear of the unit. The
large terminal block (marked X-Y-Z) is for power supply connections. The smaller auxiliary terminal
block (marked 1-2-3) is for connection to a fire protection circuit, or a danger switch.
All units are provided with two knockouts: a 3/4 conduit size for power supply and a 1/2" conduit
size for auxiliary terminal block wires. Both knockouts are located on the rear leg channel and are
accessible by removing the rear panel.
2. Remove rear panel. Mount suitable 3/4" conduit fitting in power supply knockout. The knockout
hole for 1/2" conduit fitting is covered with a closure plug. Remove this plug and mount a 1/2"
conduit fitting for connections to auxiliary terminal block.
Caution: Do not remove closure plug covering 1/2" size knockout opening if
connections to a fire protection circuit are not required. Removal of the closure plug
under this condition may result in a shock hazard.
3. Connect field wire to the power terminal block as indicated on wiring diagram. Wire must be of the
type suitable for 90 °C service and of thickness as indicated on marking on rear panel.
Field wire connections to auxiliary terminal block must be of size indicated on marking on rear panel
and suitable for 90 °C service. Lead wires to the auxiliary terminal block must be connected per
instructions on the wiring diagram located on rear panel; depending on whether the fire protection
circuit has a Normally Open (N.O.) or a Normally Closed (N.C.) Switch.
The auxiliary terminal block wiring must not be changed if connections to a fire protection system are
not made. The fryer is factory assembled for operating without connections to a fire protection system.

Caution: Installing personnel should be guided by National Electrical Code NFPA
Number 70-1978(Latest Edition), and applicable local codes.
Checking Thermostat Calibration:
The fryer thermostat is carefully calibrated at the factory so that dial settings match actual frying
compound temperatures. Field re-calibration is seldom necessary unless the unit has been
mishandled in transit or abused. Re-calibration should not be resorted to unless considerable
experience with cooking results definitely proves that the control isn't maintaining the temperature to
which the dial is set.
1. To check compound frying temperatures when re-calibrating, use a precision test instrument, or a
good grade mercury thermometer. Fill fry tank with frying compound to "FULL" mark.
2. Frying compound temperature should be checked at the center of the tank, approximately 1" to 1
1/2" below surface of frying compound.
3. Turn the dial of the thermostat being checked to the 350 °F mark.

NOTE: These values are nominal ratings. Field
wire connections must be capable of withstanding
anticipated surges.
Replace rear panel. Ensure the equipment is grounded
by installing a grounding lead to ground lug located
near terminal block.
