Cleaning, Sanitation and Maintenance - A and C Series
This ice system requires three types of maintenance:
•
Remove the build up of mineral scale from the ice
machine's water system and sensors.
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.
1. Remove the front panel.
2. Remove the evaporator cover.
3. If the machine is operating, push and release the
Harvest button. When the machine completes the
Harvest cycle it will stop. If the bin is full (b shows
in display) push and release the Off button.
4. Remove all ice from the storage bin or dispenser.
5. Push and release the Clean button. The yellow
Clean light will blink and the display will show C.
The machine will drain the reservoir and refill it.

to circulate in the water system for at least 10
minutes.

least 20 minutes.
10. Push and release the Off button. The clean cycle
will stop and the display will show O.

period of time and significant mineral scale remains,
repeat steps 5 - 10.

cleaner to 12 ounces of water.
12. Remove curtain from unit.
13. Locate ice thickness sensor. Squeeze mounting
