F. Safety Devices
1. High Pressure Switch
If pressure on the high-side of the unit exceeds Hoshizaki specications, a high pressure
switch activates and interrupts power to the compressor relay. This shuts down the
compressor until the pressure returns to an acceptable level.
2. Compressor Short Cycle Timer
There is a 2-minute minimum off-time for the compressor.
3. Compressor Protector
If combined temperature/amperage value is above the limit specied by the compressor
manufacturer, the compressor protector operates independently to turn off the
compressor. The compressor protector shuts down the compressor until the temperature/
amperage value returns to an acceptable level.
4. Defrost Protection
a) Cabinet
Primary defrost termination is controlled by the defrost thermistor. However, two
additional safeties are also present:
•DefrostTimeTermination-1hour40minutemaximum
•DefrostBackupTemperatureTermination-Controlled by a thermostat that is in-line
with the heater and independent of the control board.
