Water Supply
A water hammer arrestor (meeting ASSE-1010 Standard or equivalent) should be installed (supplied
by others) in the common water supply line at the service connection.
Water must be proper hardness. Higher hardness may cause excessive formation of lime scale.
The plumber connecting this machine is responsible for making certain that water lines are
THOROUGHLY FLUSHED OUT BEFORE connecting to the dishwasher. This "flush-out" is necessary
to remove all foreign matter, such as chips (resulting from cutting or threading of pipes) pipe joint
compound from the lines; or, if soldered fittings are used, bits of solder or cuttings from the tubing.
Debris, if not removed, may lodge in the dishwasher's plumbing components and render them
inoperative. Manual valves or solenoid valves fouled by foreign matter and any expenses resulting from
this fouling, are NOT the responsibility of the manufacturer.
Water supply requirements are as follows:
MODEL TEMPERATURE FLOWING PRESSURE
LXiC 140° F Minimum 15 to 25 psi
LXiH 110° F Minimum 15 to 25 psi
If flowing pressure exceeds 25 psi, a pressure reducing-valve (not supplied) must be installed in the
supply line.
CAUTION: The water pressure regulator must have a relief bypass. Failure to use the proper
type of pressure regulator may result in damage to the unit.
If flowing pressure is less than 15 psi, improper machine operation may result.
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 10-11.
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.
PLUMBING CONNECTIONS
WARNING: PLUMBING CONNECTIONS MUST COMPLY WITH APPLICABLE SANITARY, SAFETY
AND PLUMBING CODES.
Drain
A drain hose,
3
/4" diameter and 6' long, is provided. This should be securely plumbed into the sink
drain. Use care not to kink hose. See installation diagrams in this manual. Drain must have a minimum
flow capacity of 4 gallons per minute.
