A. Cleaning and Sanitizing Instructions
HOSHIZAKI recommends cleaning this unit 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.
