Things To Remember
l
Water enters only during the defrost cycle
Therefore the first cycle will be completed
without water in the system.
l
As the room and water temperatures vary, so
will the amount of ice produced. This means
that higher operating temperatures will result
in reduced ice production.
l
The unit will shut off when ice in the storage
bin touches the bin thermostat well and will
automatically cycle to keep the bin full.
l
The storage bin is not refrigerated and some
melting will occur. This also varies with the
room temperature.
l
The unit needs good air circulation to
perform efficiently. Keep the front grille and
the condenser clean.
l
The water system, including filter screen in
the water inlet solenoid valve, needs to be
cleaned periodically for good circulation.
Instructions are located on the inner door
panel.
