Initial startup or startup after automatic shut-off
1. Water Purge
The water fill valve and the hot gas valve are energized
for 2.9 minutes (175 seconds). This ensures that the
ice making cycle starts with fresh water, and that the
refrigerant pressures are equalized prior to refrigeration
system start-up.
2. Refrigeration System Start-up
The compressor starts 2.9 minutes (175 seconds) after
the water fill valve and hot gas valve are energized. (The
water fill valve and hot gas valve remain energized for 5
seconds during compressor start-up, and then shut off.)
The compressor remains on throughout the entire freeze
and harvest cycles.
3. Freeze Cycle
The condenser fan motor and water pump are energized
and remain on throughout the entire freeze cycle. An
even flow of water is directed across the evaporator and
into each cube cell, where it freezes. The control system
automatically determines the length of the freeze cycle by
monitoring the temperature of the refrigeration system
liquid line.
