Water System

Water enters the machine through the 3/8" male flare
at the rear of the cabinet, goes to the water reservoir
which it enters through the float valve.
The float valve maintains a constant level of water in
the reservoir and evaporator, as water flows out the
bottom of the reservoir tank to fill the evaporator.
Reservoir overflow or evaporator condensation is
routed to the drain. Water cooled models have a
separate water circuit for the cooling water: it enters
the fitting at the rear, goes to the water regulating
valve, then to the water cooled condenser and down
the drain.
Water Level
Water Level: The correct water level should be
checked when the machine is making ice. Check
the water level in the reservoir and compare it to the
horizontal line molded into the side of the reservoir.
The correct level should be between 1/8" above and
1/4" below the line. If needed, bend the float arm up
or down to adjust the water level.
