H. Safety Devices
1. Compressor External or Internal Overload
If combined temperature/amperage value is above the limit specied by the
compressor manufacturer, the compressor overload operates independently to turn
off the compressor. The compressor overload de-energizes the compressor until the
temperature/amperage value returns to an acceptable level.
2. Short-Cycle Protection
There is a 2-minute minimum off-time and on-time for the compressor.
Note: Time may vary with compressor overload or high-pressure switch activation.
3. High-Pressure Switch
If pressure on the high-side of the appliance exceeds Hoshizaki specications, the
high-pressure switch activates and interrupts the compressor circuit, de-energizing the
compressor until the pressure returns to an acceptable level.
I. Cooling Performance
Be sure the appliance is properly installed and located for optimum cooling performance.
If cooling performance is not at its optimum level, check the following items:
• Door(s) opened too often.
• Door(s) left open. Close.
• Dirty air lter and/or condenser. Clean.
• Cabinet too tightly packed or cabinet air inlet/outlet blocked. Allow some space between
items to ensure good air ow.
• Warm or hot foods inside. Take them out until they cool down more.
• Ambient temperature too high. Avoid installation near high heat producing equipment or
exposure to direct sunlight.
• Temperature setpoint too high. Readjust it to a lower temperature.
• Appliance in defrost cycle. The cabinet temperature may rise temporarily during the
defrost cycle, but this will not affect the food inside.
J. Cabinet Condensation
In the event condensation develops on the cabinet exterior, check the following items:
• Door(s) left open. Close.
• Ambient humidity too high. In high humidity areas it may be necessary to wipe off the
cabinet frame occasionally.
