c) Pump-Out Timer (S4 dip switch 3 & 4)CAUTIONLeave in the factory default position; otherwise, the drain valve and water valvewill not operate at pump out.When a freeze cycle is completed, the pump motor stops, and the icemaker resumesoperation in 2 seconds. Then, during cycles when a pump out is called for, the pumpmotor drains the water tank for the time determined by the pump-out timer. Thepump‐out timer also acts in place of the harvest timer during cycles with a pump out. Thepump-out timer setting also determines whether the inlet water valve is open or closedduring pump-out.The pump-out timer is factory-adjusted. Leave in the factory default position; otherwise,the drain valve and inlet water valve will not operate at pump out.T1: Time to drain the water tankT2: Harvest timer at pump outDip Switch Setting Time (seconds) InletWaterNo. 3 No. 4 T1 T2 ValveOFF OFF 10 150 closedON OFF 10 180 closedOFF ON 10 120 openON ON 20 180 closedDepending on the pump-out frequency control setting (dip switch 5 & 6), pump outoccurs every cycle, or every 2nd, 5th, or 10th cycle.d) Pump-Out Frequency Control (S4 dip switch 5 & 6)The pump motor drains the water tank at the frequency set by the pump-out frequencycontrol.The pump-out frequency control is factory-adjusted to drain the water tank every10 cycles, and no adjustment is generally required. With dip switches 5 and 6 in thefactory default position, the 1st pump out occurs after the 11th freeze cycle and every10th cycle thereafter. However, where water quality is bad and the icemaker needs apump out more often, the pump-out frequency can be adjusted as shown in the tablebelow.Dip Switch SettingFrequencyNo. 5 No. 6OFF OFF every cycleON OFF every 2 cyclesOFF ON every 5 cyclesON ON every 10 cycles21
