B. Cleaning and Sanitizing Instructions

The icemaker 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.

• Do not leave the icemaker unattended when panels are off.

NOTICE

To prevent damage to the water pump seal, do not leave the control switch in the 
"WASH" position for extended periods when the water tank is empty.

IMPORTANT

• 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.

• 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.

Preparation

1) Remove the front panel, then move the control switch to the "OFF" position. After 3 min., 

move the control switch to the "ICE" position, then replace the front panel. 

2) After 3 min., remove the front panel, then move the control switch to the "OFF" position.
3) Remove all ice from the dispenser unit/ice storage bin. 

WARNING! If on a dispenser 

unit, turn off the dispenser unit power supply after dispensing the ice.
