OPERATING INSTRUCTIONS
ICEMAKER OPERATING INSTRUCTIONS
A temperature sensing bulb located in the storage hopper starts and stops the icemaking process (compressor)
in response to the ice level in the hopper. With this ice level control “calling”for ice (hopper ice level is low), the
total cycle timer energized. This timer , in turn energizes the harvest and agitation timers for their respective
“on”times. The chart below details this sequence of events:

At the 34 second point in the cycle, the hot gas solenoid valve closes and ice begins to form on the stainless
steel tubing coils of the evaporator. Ice will continue to form on these coils for the remainder of the cycle time
(*seconds). At the end of the ice making cycle, the total cycle timer (repeat) starts the harvest portion of the
cycle again.
When ice contacts the control bulb in the storage hopper, the control switches the compressor off. This control
(thermostat) also switches off power to the total cycle timer. With power de-energized, the timer resets itself to
the “start”portion of the cycle. Therefore, the unit will always start with the hot gas/harvest portion of the ice
making cycle to ensure that the evaporator is cleared of any remaining ice.
