MC222 and Condensing Unit
Remote Low Side User Manual
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.
The ice machine's water system should be cleaned and sanitized a minimum of twice per year. Sanitize the
ice storage bin as frequently as local health codes require, and every time the ice machine is cleaned and
sanitized.
Preparing to Clean:
1. Remove the front panel.
2. Remove the evaporator cover.
Scale Removal:
3. Push and release the Clean button. The yellow
Clean light will blink and the display will show C.
The machine will harvest any ice, drain the reservoir
and begin to refill it.
4. Observe code display, when it blinks the characters
"A d 1" immediately go to the next step.
5. Pour the below specified amount Scotsman Clear
1 ice machine scale remover into the reservoir. The
unit will circulate the scale remover, then drain and
flush it. This will take 35 minutes, then the machine
will stop and the display will show O.
