Cleaning, Sanitation and Maintenance
This ice system requires three types of maintenance:
• Remove the build up of mineral scale from the ice
machine’s water system and sensors.
• Sanitize the ice machine’s water system and the
ice storage bin or dispenser.
• Clean the remote air cooled condenser.
It is the User’s responsibility to keep the ice machine and ice storage bin in a sanitary condition. Without
human intervention, sanitation will not be maintained. Ice machines also require occasional cleaning of their
water systems with a specifically designed chemical. This chemical dissolves mineral build up that forms during
the ice making process.
Sanitize the ice storage bin as frequently as local health codes require, and every time the ice machine is
cleaned and sanitized.
The ice machine’s water system should be cleaned
and sanitized a minimum of twice per year.
