OPERATION: Water
Water enters the machine through the 3/8" male
flare at the rear of the cabinet, goes to a strainer
and then to the water reservoir which it enters
through the float valve. The water then goes out
the bottom of the reservoir tank to the bottom of
the evaporator.
Reservoir overflow, evaporator condensation and
water in the sink are all 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.
The water dispensing station adds an
additional water circuit. When the water
station glass filler lever is pushed, a switch
closes a circuit to an electric water valve, and
water is dispensed.

Note: The correct water level is determined when
the machine is operating. Check the water level
and compare it to the line molded into the side of
the reservoir. The water level should be between
1
⁄
8
" above and
1
⁄
4
" below the line.
If needed, adjust the water level by bending the
float arm.
