BROIL TEMPERATURE STABILIZER CONTROL
The Models 732/735, 532E/535E & 522E are equipped with a Broil Temperature Stabilizer
Control that senses when the broiler is being used, and adjusts the temperature to keep the
broiler hot during heavy use. The control consists of two parts - a temperature probe to sense
the internal temperature of the broiler, and the control itself.
CALIBRATING THE BROIL STABILIZER CONTROL
In order to assure proper operation, the Broil Stabilizer Control must be calibrated for operation
in the restaurant. Every broiler will calibrate slightly differently, depending on supply voltage,
ventilation, etc. Follow these step by step instructions when the broiler is new, and once per
month after.
Step 1: Be sure all pieces of the broiler are in place. Make sure the broiler is plugged in and
the exhaust hood is turned on. Turn the broiler on by turning the main power switch to
the right. Turn on the conveyor belts using the motor breaker switch.
Step 2: Set the temperature (bottom number) to 200° F. Use the up or down arrows on the con-
trol to set the temperature. The bottom number is the set temperature and the top num-
ber is the actual temperature.
Step 3: Allow the broiler to heat up for 40 minutes. During this time, the actual temperature will
climb. Wait until the actual temperature stabilizes before proceeding.
Step 4: Set the ATC (bottom number) to 200° F higher than the actual temperature. For exam-
ple, if the broiler stabilizes at 700° F, then the proper setting should be 900° F.
WARNING
The broiler can be damaged if this control is not set according to instructions.
