A. Cleaning and Sanitizing Instructions
Hoshizaki recommends cleaning and sanitizing this unit at least once a year. More
frequent cleaning and sanitizing, however, may be required in some existing water
conditions.
1. To prevent injury to individuals and damage to the icemaker, do not use
ammonia type cleaners.
2. Carefully follow any instructions provided with the bottles of cleaning and
sanitizing solution.
3. Always wear liquid-proof gloves and goggles to prevent the cleaning and
sanitizing solutions from coming into contact with skin or eyes.
4. To prevent damage to the water pump seal, do not operate the icemaker
with the control switch in the "WASH" position when the water tank is empty.
1. The cleaning valve is opened during cleaning and sanitizing to allow solution
flow to the inside of the evaporator. It should be closed for all icemaking
operation. The compressor will not operate unless this valve is completely
closed.
2. To close the cleaning valve, the valve handle should be at a right angle
to the valve body. To open the cleaning valve, the valve handle should be
parallel to the valve body.
