INSTALLATION

WATER SUPPLY: Water

pressure for the water supply
should be minimum 18 to 176 psi.
The water inlet valve is on the
right rear of the machine.

The dishwasher should preferably
be connected to a hot water supply
(2). If cold water supply is used,
the washing times will be longer.
(See Cycle Data page # )

It’s important that the water supply line and shut-off valve have a sufficient flow volume,
at least 3 gallons (12 liters) per minute must be able to pass through the line.

ELECTRICAL CONNECTIONS:

The dishwasher comes with a 6’
(1.8cm) electrical cord for 110-120
volts, 15/20 supply. This cord
should be plugged into the 110-120
volt outlet under the sink. If the cord
is not long enough or if a hard wire
installation is needed, see illustration
below.

DRAIN: A drain hose is provided with
the dishwasher which is connected to the
back of the unit to form a high loop.
The access hole for the drain line should
be at a minimum of 20” from the flood.
If the hose provided is not long enough,
extend it with a 7/8” copper tube. Do
not use any fittings anywhere in the
drain line that are less than 7/8”. If the
drain line is going to be connected to a
waste disposer, be sure to remove the
knock out pr plug from the fitting on the
disposer before connecting drain line. The dishwasher drain hose has a factory installed
check valve. Do not add an additional check valve.

Different ways to connect the drain line: (A) Typical drain connecting to sink plumbing
before trap (high loop drain). (B) Connection to an air gap, then to the trap. (C)
Connection to a waste disposer with air gap.

CAUTION: Failure to provide either the proper drain connection height above floor
level or a 20” high loop will result in improper draining of the dishwasher, which will
cause damage to the dishwasher.

NOTE: The drainage hose can be extended to a maximum length of 10 feet. Joints and
jointed tubes, if any must have an Inside Diameter (ID) of a least 7/8”. No part of the
drain hose must have a position higher then 35” above the floor. The hose must not be
drawn straight to a floor well or its equivalent. The hose might then function as a siphon­emptying the dishwasher.
