2.2.2. Plumbing

Notice to Plumber: The plumber connecting this machine is responsible for making certain that the
water lines are THOROUGHLY FLUSHED OUT BEFORE connecting to the dishwasher.
The machine is equipped with a gate valve with a ½" female NPT connection located at the lower left-
hand corner (facing the back) of the machine. A 140°F water line should be plumbed to this point. The
water line used must be of sufficient length and flexibility to permit the machine to be moved for cleaning.
A 1" male NPT fitting is provided for the drain connection on the discharge port of the diverter valve
(lower, right-hand corner of machine). This fitting may be removed and user provided hardware might be
used if necessary to facilitate compliance with local plumbing codes. Code requires that the drain
discharge provide an air gap no less than 1" or two pipe diameters; whichever is greater, above the flood
level rim of an approved floor drain.
Ask your municipal water supplier for details about your local water conditions prior to installation.
Recommended water hardness is 3 grains per gallon or less.
Note: high iron levels in the water supply can cause staining and may require an iron filter. High chlorine
levels in the water supply can cause pitting and may require a chloride removal system.
If an inspection of the dishwasher or booster heater reveals lime buildup after the equipment has been in
service, water treatment is recommended. If water softener is already in place, ensure there is a

sufficient level of salt.
