6. Harvest
The air compressor (when used) remains energized
and the harvest valve(s) remains open. The refrigerant
gas warms the evaporator causing the cubes to slide,
as a sheet, off the evaporator and into the storage bin.
Energized Control Board Lights-
Single Evaporators = Left Bin (green), Harvest (red)
Twin Evaporators = Left & Right Bin (green), Harvest
(red)
Quad Evaporators = All Curtain Switches (green),
Liquid Solenoid (red), Harvest (red), All Harvest Valves
(red)
Single evaporator models - The sliding sheet of
cubes opens the water curtain and bin switch.
The momentary opening and re-closing of the bin
switch will terminate the harvest sequence and return
to the freeze sequence (Step 3 - 4.)
Twin & Quad evaporator models - The sliding sheet
of cubes opens the ice damper and bin switch. The
momentary opening and re-closing of the bin switch
de-energizes the harvest valve for the evaporator.
When all of the bin switches have opened and closed
the ice machine will terminate the harvest sequence
and return to the freeze sequence (Step 3 - 4.)
Energized Control Board Lights (once ice drops)-
Single Evaporators = Left Bin (green flashes once)
Twin Evaporators = Left & Right Bin (green flashes
once)
Quad Evaporators = All Curtain Switches (green
flashes once), Liquid Solenoid (red)
