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 or replace the air filter and clean the air
cooled condenser (air cooled models only).
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.
