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: 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.
