WATER REQUIREMENTS
Proper water quality can improve ware washing performance by reducing spotting, lowering chemical supply costs, enhancing effectiveness of labor, and extending equipment life. Local water conditions vary from one location to another. The recommended proper water treatment for effective and efficient use of this equipment will also vary depending on the local water conditions. Ask your municipal water supplier for details about local water specifics prior to installation.
Recommended water hardness is 4 – 6 grains of hardness per gallon. Chlorides must not exceed 50 parts per million. Water hardness above 6 grains per gallon should be treated by a water conditioner (water softener or
Sediment, silica, chlorides, or other dissolved solids may lead to a recommendation for particulate filtration or reverse osmosis treatment.

PLUMBING CONNECTIONS
WARNING: PLUMBING CONNECTIONS MUST COMPLY WITH APPLICABLE SANITARY, SAFETY, AND PLUMBING CODES.
DRAIN CONNECTION
The drain connection is made using 2" pipe.
If a right hand drain is desired, it can be changed from the standard
If a grease trap is required by code, it should have a minimum flow capacity of 42 gallons per minute.
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.
Minimum water temperatures are listed below:
Sanitizing Mode | Wash | Rinse |
Hot Water | 150°F (66°C) | 180°F (82°C) |
Chemical (Normal Duty) | 120°F (49°C)* | 120°F (49°C)* |
Chemical (Light Duty) | 130°F (54°C)* | 120°F (49°C)* |
* Temperatures shown are minimum; recommended temperature is 140°F (60°C).
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
A pressure gauge (Fig. 1) is provided for verification of proper water pressure. Present models monitor the water pressure when the solenoid valve is open and water is flowing. On earlier models where the pressure gauge was connected into a petcock, the petcock MUST always remain closed except when making an instantaneous check of flowing pressure.
