Service manual

OPERATION: Water

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 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 sensor

detects a container in front of it, the control board

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

" above and " below the line.

If needed, adjust the water level by bending the

float arm.
