OPERATING INSTRUCTIONS
A temperature sensing control bulb, located in the storage hopper, starts and stop the icemaking process (com-
pressor) 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 is energized. This timer, in turn, energizes the harvest timer for its’respective “on”
times. The chart below details this sequence of events.

1. Hot gas solenoid valve closed.
At the 35 second point in the cycle, the host 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.
At the end of the icemaking cycle, the total cycle timer (repeat starts sht 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.
