III. Cleaning and Maintenance
IMPORTANT
Ensure all components, fasteners, and thumbscrews are securely in place after
any cleaning or maintenance is done to the equipment.
A. Cleaning and Sanitizing Instructions
Hoshizaki recommends cleaning this icemaker at least once a year. More frequent
cleaning, however, may be required in some existing water conditions.
WARNING
1. To prevent injury to individuals and damage to the icemaker, do not use
ammonia type cleaners.
2. Always wear liquid-proof gloves to prevent the cleaning and sanitizing
solutions from coming into contact with skin.
3. Carefully follow any instructions provided with the bottles of cleaning and
sanitizing solution.
4. Never run the icemaker when the water tank is empty.
IMPORTANT
1. The cleaning valve is used to allow solution flow to the inside of the
evaporator during the cleaning and sanitizing operation. It should be closed
for all icemaking operation. The compressor will not operate unless this valve
is completely closed.
2. To open the cleaning valve, the valve handle should be parallel to the valve
body. To close the valve, the valve handle should be at a right angle to the
valve body.
