Evaporator
To keep the evaporator in peak performance, the ice maker should be cleaned with an approved ice
machine cleaner at least twice a year, more often if water conditions cause mineral build up, using an
approved food grade ice machine cleaner. The water pump is used to circulate ice machine cleaner
through the system. Refer to cleaning instructions below for complete cleaning instructions.
Ice Machine Cleaning Instructions
An important part of ice flaker maintenance is to clean it frequently so that the water passages are not
clogged and the freezing surface is clear and free of scale caused by calcium and iron deposits.
Frequency of cleaning depends upon the quality of water. In extreme hard water areas, it may be
necessary to clean the flaker as often as every 2 months whereas in normal or "soft" water areas twice a
year may be sufficient.
When cleaning is necessary, proceed as follows:
1. Turn off refrigeration compressor. If flaker is connected to a compressor rack, close the liquid
line shut off valve.
2. Remove all ice in storage bin.
3. Close water supply shut off valve.
4. Drain water from drain connection in water sump. Some models are equipped with a drain
valve, others have a drain plug, located below the water float valve connection.
5. Prepare the cleaning solution: Mix 8 oz. of ice machine cleaner with 3 quarts of hot water.
Water should be between 90-115
°
F. If using an alternate ice machine cleaner such as Virginia cat no.
