Water must be proper hardness. Recommended hardness range is 4 – 6 grains per gallon. Lower hardness can promote corrosion, higher hardness may cause excessive formation of lime scale.
The plumber who connects this machine is responsible for making certain that water lines are THOROUGHLY FLUSHED OUT BEFORE connecting to the dishwasher. This
Water supply requirements are as follows:
MODEL | TEMPERATURE | FLOWING PRESSURE |
LX18, LX30 | 180°F Minimum | 15 to 25 psig |
LX18H, LX30H, LX40H | 140°F Minimum | 15 to 25 psig |
LX18C, LX30C, LX40C | 140°F Minimum | 15 to 25 psig |
LX30C w/booster | 100°F Minimum | 15 to 25 psig |
If flowing pressure exceeds 25 psig, a pressure reducing valve (not supplied) must be installed in the supply line. CAUTION: The water pressure regulator must have a relief
A manual shutoff valve (not supplied) should be installed upstream of the fill hose to accommodate servicing the machine.
It is recommended that a line strainer (not supplied) be installed in the supply line between the manual shutoff valve (not supplied) and the connection point on the machine. Make plumbing connections with 1/2" minimum copper piping OD (3/4" recommended), with a 3/4" male garden hose fitting (not supplied). See installation diagrams, pages
NOTE: Iron in the water supply can cause staining. An iron filter is recommended for iron concentration greater than 0.1 part per million. High chloride levels in the water supply can cause pitting. A chloride removal system is required if levels exceed 50 parts per million.
