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 o󰀨.
• 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 ow
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.
