The cabinet is equipped with a special, low-heat-density, heating
cable. Through the Halo Heat concept, the heating cable is
mounted against the walls of the warming compartment to
provide an evenly applied heat source controlled by a
thermostat. The design and operational characteristics of the
cabinet eliminates a heat circulating fan. Through even heat
application, the quality of a food product is maintained for many
hours.

Whenever the thermostat is turned up, the pilot 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 the pilot light does not indicate after
normal start-up, the main power source, thermostat, and/or the
pilot light must be checked. If a warming compartment does not
hold the temperature as dialed, the calibration of the thermostat
must be checked. (See the paragraph on thermostat calibration.)
If a warming compartment fails to heat or heats continuously
with the thermostat OFF, the thermostat must be initially
checked for proper operation. If all is in order, a continuity and
resistance check of the heating cable should be made. (See the
circuit diagram.)

The thermostat is precision calibrated at the factory. Normally,
no adjustment or recalibration is necessary unless 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 displaces the accuracy of the
thermostat calibration.
A thermostat should be checked or recalibrated by placing a
quality temperature indicator at the center of an empty warming
cavity. DO NOT CALIBRATE WITH FOOD PRODUCT IN THE
WARMING CABINET. The temperature must be allowed to
stabilize at one particular setting for at least one hour. The
center of the thermal swing of the cavity temperature should
approximately coincide with the thermostat setting.
The calibration screw of the thermostat is located in the dial
shaft, and should be adjusted with great care and caution. With
the shaft held stationary, a very slight clockwise motion of the
calibration screw APPRECIABLY lowers the thermostat setting
while a reverse, counter-clockwise motion results in the opposite
condition. After achieving the desired cycling of the thermostat,
the calibration screw must be sealed in place with a few drops of
sealant. [Red nail polish or equivalent is acceptable.]
