WATER CONNECTION

A suitable water hammer arrestor should be installed in the water line just ahead of the dishwasher.

Without Electric or Gas Booster Water Heater

The water supply line is connected to the line strainer (Fig. 1) with 3/4" pipe. A manual shut off valve and pipe union are required. The required incoming water supply temperature follows:

Proper dishwasher operation requires a flowing pressure of 20 ± 5 psig at the dishwasher. If the flowing pressure exceeds 25 psig, a pressure reducing valve (not supplied) must be installed in the water supply line. CAUTION: The water pressure regulator must have a relief by-pass. Failure to use the proper type of pressure regulator may result in damage to the unit.

A pressure gauge (Fig. 1) is provided for verification of proper water pressure. The water pressure is monitored when the solenoid valve is open and water is flowing.

With Electric Booster Water Heater

The water supply line is connected to the flow control ahead of the line strainer below the booster with 3/4" pipe. A manual shut off valve and pipe union are required.

The water supply should have a minimum temperature of 110°F and a flowing pressure of 15 – 25 psig at the pressure gauge on top of the machine. If the flowing pressure exceeds 25 psig, a pressure reducing valve (not supplied) must be installed in the water supply line. CAUTION: The water pressure regulator must have a relief by-pass. Failure to use the proper type of pressure regulator may result in damage to the unit.

Incoming water temperature below 110°F may require the wash cycle time to be extended from 40 to 60 seconds. To have the cycle time adjusted, contact your local authorized Hobart Service Office.

When the fill / final rinse valve is on, water from the booster tank enters the dishwasher through the final rinse arms. During the rinse cycle, this water is 180°F. Water will likely dribble out of the lower rinse arm into the tank between cycles due to the natural expansion of water as it is being heated.

GAS TANK HEAT (When Specified)

Check the gas data plate attached to the dishwasher or the tag attached to the incoming gas piping for the type of gas to be used. Connect the gas supply to the 1/2" NPT gas inlet at the manual gas valve. The burner is not adjustable. The maximum flowing inlet gas pressure must not exceed the Maximum value in the table. If line pressure exceeds the Maximum value in the table, an additional regulator valve (not supplied) must be installed in the supply line.
