Scotsman Ice Machine General Cleaning & Maintenance

General Cleaning Procedure

• Remove the front panel

• Remove the evaporator cover

• 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

• Curtain(s) must be in the closed position. Move curtain(s) to release any ice trapped after ice is harvested

• Observe code display, when it blinks the characters “A d 1” immediately go to the next step

• Pour 8 ounces (C0322 or C0330) or 10 ounces (C0522, C0530 or C0630) or 12 ounces (C0830 or C1030) of 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

• If unit has not been de-scaled for an extended period of time and significant mineral scale remains repeat steps 4-6

• Mix a cleaning solution of 1 oz of ice machine scale remover to 12 ounces of water

• Locate curtain, push in on edge of curtain by pivot pin to release it. Pull curtain out of machine

• Remove water distributor from ice machine

• Remove cover

• Inspect distributor for restricted orifice holes, flush out any debris and open any restricted holes

• Return cover to distributor, be sure it is fully attached

• Locate ice thickness sensor. Squeeze mounting legs together to release sensor

• Wash the sensor and the adjustment screw with ice machine scale remover solution, rinse with clean water

• Also wash the water distributor and curtain with the ice machine cleaner solution

• Squeeze tabs together, slide out until it stops, then lift to remove

• 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

• Rinse and return probes to holder

• 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

• Thoroughly wash all surfaces of the ice thickness sensor, water level sensor, curtain and water distributor with the sanitizer solution

• Wash all interior surfaces of the freezing compartment, including evaporator cover and right side panel liner with the sanitizer solution

• Return water level sensor, ice thickness sensor, water distributor and curtain to their normal positions. Be sure water level sensor and ice thickness sensor are completely dry

• Push and release the Clean button. The yellow Clean light will blink and the display will show C.

• The machine will go through a harvest cycle, drain the reservoir and begin to refill it

• Observe code display, when it blinks the characters “Ad1” immediately go to the next step

• Return all panels and covers removed to their original positions

• Push and release the On button to resume ice making

Ice Storage Bin Cleaning Procedure

• Remove and discard all ice

• Mix a solution of 7 ounces of Scotsman Clear 1 ice machine scale remover in 84 ounces of potable water and wash all interior surfaces of the ice storage bin to remove any mineral scale build up.

• Pour excess cleaner solution into the bin’s drain

• Return it to its original position

• Do not operate the machine without the filter in place except during cleaning

• If the machine has been operated without a filter the air cooled condenser fins will need to be cleaned

• They are located under the fan blades. The services of a refrigeration technician will be required to clean the condenser

Exterior Panels Cleaning Procedure

• The front, top and side panels are durable stainless steel. Fingerprints, dust and grease will require cleaning with a good quality stainless steel cleaner

• Use a sanitizer or a cleaner that contains chlorine on the panels
