1. Freeze Cycle
Turn the toggle switch to ON. The compressor, and
water pump will energize, starting the freeze cycle.
The pump sprays water into the inverted cups. The
water freezes layer by layer, until an ice cube forms in
each cup.
At the same time the compressor starts, the
condenser fan motor (air-cooled models) is supplied
with power throughout the freeze and harvest cycles.
The freeze cycle continues and the evaporator
thermostat reaches the adjusted set point.


Mechanical Timer

freeze time the relays change position and the harvest
cycle is initiated.

SCR Timer
The thermostat energizes the time delay relay. When
the timer reaches setpoint (11.5 minute factory setting)
the harvest cycle is initiated.
