TROUBLESHOOTING AND DIAGNOSTICS

WATER AND ITS EFFECT ON ICE MAKING

Quality ice is defined as hard, clear, cold and free of taste or odor. All ice makers will provide this type
of quality ice only if the water used to produce the ice is pure and free of mineral or chemical contami-
nation. The chart below helps diagnose problems that can affect ice production.

RECOMMENDATIONS:
Water softeners or polyphosphate feeders are not cure-alls, but do reduce and, in some cases,
prevent scale buildup. Use Ice Maker Cleaner (P/N 8171307).
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 filter can limit
the water flow to the unit and limit its capacity to produce sufficient ice.
Water Hardness Test Kit: A Water Hardness Tes Kit (P/N 4171690) is available from FSP Part
Distribution.
