Connection to Washer
These washers were designed for direct wiring into the power
supply. The washer must be electrically grounded in accordance
with all local codes or, in the absence of local codes, with the
National Electrical Code, ANSI/NFPA 70, latest edition,
or Canadian Electrical Code, CSA C22.1.
Direct Wire Installation:
Power supply cable must match power supply (4-wire or 3-wire)
and be:
Flexible armored cable or nonmetallic sheathed copper cable
■
(with grounding wire), in a flexible metallic conduit, to avoid
conductor breakage due to vibration. All current-carrying
wires must be insulated.
Copper wire of appropriate gauge for amperage requirement
■
(see "Manufacturer's Recommended Minimal Conductor
Section"). Stranded wire is recommended. Do not use
aluminum wire.
Equipotential bonding:
In addition to an equipment-grounding conductor that must
be run with the circuit conductor and be connected to the
equipment grounding terminal, all washers or appliances in the
vicinity must be permanently interconnected with a connector.
The external connection points serve for this purpose. See
illustration below.
The cross-sectional area of the conductor must be at least
electrically equivalent to the cross-sectional area of the copper
conductor.

Water Supply Requirements

Water supply requirements are as follows:
Valved hot and cold water supply with a water pressure
■
between 14.5 and 116 PSI (100–800 kPa). Water pressure
between 43 and 73 PSI (300–500 kPa) is recommended.
A hot water heater or boiler supplying an adequate
■
amount of water between 120–160°F (49–80°C). The water
temperature within the washer is controlled to a maximum
temperature that is set in the program. The amount of hot
water required to wash a load of laundry is dependent on
many factors, including the hot and cold water temperature
and the wash program selected. Average amounts of hot
water required to wash one load of laundry are shown in
the table below.

*Approximate values. Assumes 140°F (60°C) hot water supply and
70°F (21°C) cold water supply.

Drain Requirements

The washers have two 3" (76 mm) water drains on their rear
side. To connect the drains to a drain hose, use the 3" (76 mm)
elbow which is supplied with the washer. Secure the elbow with
a clamp. To maintain washer performance, do not reduce the
diameter of the drain pipe.
The washer may drain into a waste channel or directly to a drain.
The waste channel cannot be located under the washer.
■
There should be at least 4" (102 mm) between the back
of the washer and the middle of the waste channel (see
illustration below).
The waste channel must be lower than the drain pipe.
■
There should be at least a 3/4" (19 mm) air gap between
the bottom of the drain and the water level in the channel.
