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 specically 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. Remove all ice from the storage bin or dispenser.
4. 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 rell it.
Note: Curtain must be in the closed position. Move
curtain to release any ice trapped after ice is
harvested.
5. Observe code display, when it blinks the
characters “A d 1” immediately go to the next step.
6. Pour 8 ounces of Scotsman Clear 1 ice machine
scale remover into the reservoir. The unit will
circulate the scale remover, then drain and ush
it. This will take 35 minutes, then the machine will
stop and the display will show O.
Note: If unit has not been de-scaled for an extended
period of time and signicant mineral scale remains,
repeat steps 5 - 10.
7. Mix a cleaning solution of 1 oz of ice machine
cleaner to 12 ounces of water.
8. Remove curtain from unit.
9. Locate ice thickness sensor. Squeeze mounting
legs together to release sensor.
10. Remove water distributor from ice machine by
disconnecting its hose, squeezing the retaining
snaps together and pushing the distributor to the
right as far as possible. Lift up to remove. Inspect
distributor for restricted orice holes. Be sure all
holes are full open.
11. Locate water level sensor. Squeeze catches
together and pull up to remove sensor. Separate
probes from housing and wash all surfaces with
ice machine scale remover solution. Return
probes to holder.
12. Wash the metal surfaces of the ice thickness
sensor and the adjustment screw with ice machine
cleaner solution. Also wash the water distributor,
water level sensor probes and curtain with the ice
machine cleaner solution.
13. Create a solution of sanitizer. Mix 8 ounces of
NuCalgon IMS II and 5 gallons of 105-115 degree
F. potable water to create a 200 ppm active
quaternary solution.
14. Thoroughly wash all surfaces of the ice thickness
sensor, water level sensor, curtain and water
distributor with the sanitizer solution.
Ice machine scale remover
contains acids. Acids can
cause burns.
If concentrated cleaner comes
in contact with skin, ush with
water. If swallowed, do NOT
induce vomiting. Give large
amounts of water or milk. Call
Physician immediately. Keep
out of the reach of children.
