2. Portion Dispense

Agitating motor energizes for .6 seconds for every  seconds of accumulative dispense

time. A variable resistor which controls the amount of ice dispensed is located on

the control board. The gures on the label indicate dispensing time (sec.). See "II.

D.3.a) Portion Control." When shipped, the portion control is set at the minimum

dispensing time (0.6 sec.).
