Frequency: Cleaning is recommended about twice a year. The ice machine will not maintain a sanitary condition without human intervention.
Prep: Obtain food grade scale remover such as Scotsman Clear 1. You will also need a clean container, sanitizer, clean cloths and clean rubber gloves. Use of a spray bottle is recommended for ease of washing hard to reach areas.
Condensers and Air Filter Cleaning
Filters and Air Cooled Condenser
The air filter located on the lower front grill will capture airborne dust during operation. As the dirt builds up, it begins to restrict air flow and causes the refrigeration system to work less efficiently. Clean the air filter regularly.
Remove the filter by sliding it to the right until it is clear of the ice machine.
Note: It is a snap fit and the snaps may be very tight. Pull hard with two thumbs.
Remove dust and dirt by washing the filter in a utility sink.
Reinstall filter in the ice machine.
Water cooled equipment may be connected to a closed loop recirculating system or to a regular water supply.
The included water regulating valve will vary the amount of water or coolant needed to maintain a constant discharge pressure. Higher coolant temperatures will result in increased coolant flow to maintain the discharge pressure set point.
That pressure is factory set to 135 PSIG. If needed, it may be field adjusted to that set point. An access port to the adjustment stem is available on the lower back panel.
In areas with highly mineralized water, the inside of the condenser may become coated with scale. When that occurs the amount of water used by the condenser will increase, as the water regulating valve opens further to keep the discharge pressure at the set point.
Scale on the inside of the condenser may be cleaned by circulating an acid solution with an auxiliary pump.
