[d] CONTROLS AND ADJUSTMENTSThe Dip Switch is factory-adjusted to the following positions:FOR MODELS WITH MECHANICAL BIN CONTROL:DIP SWITCH NO. 1 2 3 4 5 6 7 8 9 10KM-900MRH/3 OFF OFF ON OFF ON ON ON OFF OFF ONKM-900MAH, OFF OFF ON OFF ON ON ON OFF OFF ONKM-900MWHFOR MODELS WITH THERMOSTAT :DIP SWITCH NO. 1 2 3 4 5 6 7 8 9 10KM-900MRH/3 OFF OFF ON OFF ON ON OFF OFF OFF ONKM-900MAH, OFF OFF ON OFF ON ON OFF OFF OFF ONKM-900MWHSwitch Nos. 1 and 2:Used for adjustment of the Defrost Timer.The Defrost Timer starts counting when the Thermistor reads a certain temperatureat the Evaporator outlet.Switch Nos. 3 and 4:Used for adjustment of the Drain Timer.When a freeze cycle is completed, the Pump Motor stops, and the icemakerresumes operation in 2 seconds. Then the Pump Motor drains the Water Tankfor the time determined by the Drain Timer. The Drain Timer also determines thetime to restrain completion of a defrost cycle, i.e. the minimum defrost time.Switch Nos. 5 and 6:Used for adjustment of the Drain Counter.The Pump Motor drains the Water Tank at the frequency determined by the DrainCounter.Switch No. 7:Used only on models with mechanical bin control. Dip Switch should be set“ON”.(Models with bin thermostat, Switch No. 7 should be set in the “OFF” position.)Switch No. 8:Used only for checking the Controller Board. Usually set in OFF position.23
