Electrical Components:

•Compressor

•Fan motor

•Spray pump motor

•Drain pump motor

•Drain pump switch

•Inlet water solenoid valve

•Freeze & harvest timer

•Cube size thermostat

•Hot gas valve

•Bin thermostat

The machine uses a temperature initiated, timed cycle to make ice.

A closed bin thermostat connects power to the compressor and electronic timer. The timer NO contacts close, connecting power to the water and hot gas solenoids.

The compressor starts, the inlet water solenoid valve opens and fills the reservoir. The harvest timer starts. At the end of the pre-set harvest time, the timer will open the NO contacts, stopping the inlet water valve and hot gas valve. At the same time, it closes the NC contacts, powering the fan and pump motors. This is the beginning of the freeze cycle.

The freeze cycle continues until the cube size contacts close, this starts a freeze timer. No other changes occur until the freeze timer expires, when the NC contacts open and the NO contact close, starting the harvest cycle.

The harvest cycle is time controlled. At the end of the harvest cycle the unit returns to a freeze cycle.

Bin control.

The machine's on and off modes are regulated by a bin thermostat. The cap tube for the bin thermostat is in the tube that holds the scoop. The machine will only begin ice making when the thermostat's contacts close. The machine will stop ice making whenever the bin thermostat contacts open.
