1. CLEANING
WARNING
1. Hoshizaki recommends cleaning this unit at least once a year. More
frequent cleaning, however, may be required in some existing water
conditions.
2. To prevent injury to individuals and damage to the icemaker, do not use
ammonia type cleaners.
3. Always wear liquid-proof gloves to prevent the cleaning and sanitizing
solutions from coming into contact with skin.
4. For safety and maximum effectiveness, use cleaning and sanitizing
solutions immediately after dilution.
[a] CLEANING PROCEDURE
1) Dilute 148 ml of recommended cleaner Hoshizaki “Scale Away” with 3.8 lit. of water.
2) Remove the air filter. Remove all ice from the evaporator and the ice storage bin.
Note: To remove cubes on the evaporator, move the control switch to the “OFF”

cycle starts and the cubes will be removed from the evaporator.
3) Move the control switch to the “OFF” position. Open the door.
4) Disconnect the silicone hose to drain the water. See Fig. 21. Reconnect the silicone
hose back in its correct position after all of the water has drained.
5) Pour the cleaning solution into the water tank. Move the control switch to the “WASH”
position. Close the door.
6) After 30 minutes, move the control switch to the “OFF” position.
