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.
