discharge warm (about 120

C) water out of the
condenser drain.
Freezing will continue until ice has formed adequately,
then the system will switch to a harvest mode and
the ice will release as a group, falling past the ice
sensing plate and into the bin. When ice moves the
ice sensing plate, that triggers the end of the harvest
cycle.
5. Move the On/Wash/O switch to the o position to
switch the machine o. Scoop out any ice in the

Once started, the ice machine will automatically
make ice until the ice piles up onto the ice sensing
plate, holding it open. The typical ice level when the
machine is o will be several inches below the door.
When ice level drops from use or meltage, the ice
machine will resume making ice.
Tip: To maximize ice storage, scoop the ice to the
sides and front of the bin.
Noise:
This is a commercial ice machine. It contains a
powerful compressor, and, if air cooled, a fan motor. It
will produce some noise when it is making ice. Every
eort was made during its design to minimize the
sound level but some is unavoidable.
