3. Dispense Mode Switch

The dispense mode switch has 2 positions, "CONTINUOUS" and "PORTION."

a) CONTINUOUS

When the dispense mode switch is in the "CONTINUOUS" position, ice dispenses

continuously for a maximum of 60 seconds per activation.

b) PORTION

When the dispense mode switch is in the "PORTION" position, ice dispenses for the

amount of time determined by the ice dispense time setting.

The ice dispense time control is located on the control board. The dial indicates

dispense time in seconds and is adjustable between 0.6 and 20 seconds. When

shipped, the ice dispense time control is set to the minimum dispense time of 0.6 sec.

(approximately 0.72 oz.).

and "DRAIN."

b) DRAIN

When the control switch is in the "DRAIN" position, the control switch directs

24VAC power supply to the drain valve and breaks the 5VDC to the control board

K4connector pin #4.
