B. Cleaning and Sanitizing Instructions

The appliance must be cleaned and sanitized at least once a year. More frequent 
cleaning and sanitizing may be required in some water conditions.

 WARNING

• To prevent injury to individuals and damage to the icemaker, do not use ammonia 

type cleaners.

• Carefully follow any instructions provided with the bottles of cleaning and 

sanitizing solution.

• Always wear liquid-proof gloves and goggles to prevent the cleaning and sanitizing 

solutions from coming into contact with skin or eyes.

NOTICE

The pump motor is energized continuously when the control switch is in the 
"SERVICE" position.

1. Cleaning Procedure – Icemaker

1) Dilute 10.5 fl. oz. (311 ml) of Hoshizaki "Scale Away" with 2 gal. (7.6 l) of warm water.
2) Remove all ice from the evaporator.
Note: To remove cubes on the evaporator, remove the front panel and disconnect the 

connector from the control box. See Fig. 7. Move the control switch on the control box to 
the "OFF" position and move it back to the "ICE" position after 3 minutes. The harvest 
cycle starts and the cubes will be removed from the evaporator.

3) Reconnect the connector from the front panel to the control box and replace the front
