THERMOSTAT & PILOT LIGHT SEQUENCE

Whenever the thermostat is turned “ON,” the

ndicator light will indicate the power ON/OFF

condition of the heating cable, and consequently,

the cycling of the cabinet as it maintains the dialed

cavity temperature. If this light does not illuminate

after normal start-up, the main power source,

thermostat, and/or indicator light must be checked.

If the warming cabinet does not hold the temperature

as dialed, the calibration of the thermostat must be

checked. If the warming cabinet fails to heat or heats

continuously with the thermostat “OFF,” the thermo-

stat must be initially checked for proper operation.

If these items are checked and found to be in order,

a continuity and resistance check of the heating cable

should be made. SEE CIRCUIT DIAGRAM.

The thermostat is precision calibrated at the factory.

Normally, no adjustment or recalibration is necessary

nless the thermostat has been mishandled in transit,

changed or abused while in service. A thermostat

with a sensing bulb operates on hydraulic pressure,

consequently, any bending of the bulb results in a

change in its volume, and alters the accuracy of the

thermostat calibration.

A thermostat should be checked or recalibrated by

placing a quality, thermal indicator at the center of

an empty holding cavity. DO NOT CALIBRATE

WITH ANY FOOD PRODUCT IN THE CABINET.

The thermostat should be set, and should be allowed

to stabilize at that setting for a minimum of one

hour. The center of the thermal swing of the air tem-

perature within the cabinet should approximately

coincide with the thermostat setting.

If calibration is necessary, the calibration screw

should be adjusted with great care. The calibration

screw of the thermostat is located in the thermostat

dial shaft. With the shaft held stationary, a minute,

clockwise motion of the calibration screw apprecia-

bly lowers the thermostat setting. A reverse, or

counter-clockwise motion appreciably raises the

thermostat setting. After achieving the desired

cycling of the thermostat, the calibration screw must

be sealed. Place a few drops of enamel sealant

directly on the calibration screw.
