RECOMMENDATIONS:
Water softeners or polyphosphate feeders are not cure-alls, but do reduce and, in some cases,
prevent scale buildup. Use only Ice Maker Cleaner (P/N 4396808) if there is scale buildup on
evaporator plate or in water hoses.
CAUTION: Some polyphosphate feeders cause slime buildup. Their use in low mineral content
water should be carefully considered.
NOTE: Reverse Osmosis filters are not recommended with this unit. These filters can
limit the water flow to the unit and limit its capacity to produce sufficient ice.
Water Hardness Test Kit: A Water Hardness Test Kit (P/N 4171690) is available from FSP
Parts Distribution.
