Dispense Mode Switch; Alarm Safeties - Hoshizaki DCM-500B H Instruction Manual

I. Dispense Mode Switch
The dispense mode switch has "CONTINUOUS" and "PORTION" positions. When the
dispense mode switch is in the "CONTINUOUS" position, ice dispenses continuously
for a maximum of 60 seconds per activation. 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. See Fig. 8. When shipped, the ice dispense time control is set to the minimum
dispense time of 0.6 sec. At this setting, approximately 0.72 oz. of ice is dispensed.
Approximately 1.2 oz. of ice is dispensed per second.
