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.

Multiple Single-Phase Machines in Line
When installing multiple single-phase washers into an existing
3-phase power supply, alternating the phase used as the hot
leg is recommended to evenly distribute power on the system.
See illustration.
