Electrical Requirements
It Is Your Responsibility
■ To contact a qualied electrical installer.
■ To be sure that the electrical connection is adequate and in
conformance with the National Electrical Code, ANSI/NFPA
70-latest edition, or Canadian Electrical Code CSA C22.1,
and all local codes and ordinances.
A copy of the above code standards can be obtained from:
National Fire Protection Association, One Batterymarch Park,
Quincy, MA 02269.
■ To supply the required 3 or 4 wire, single phase,
208-240 volt, 60 Hz., AC electrical supply on a separate
circuit. Circuit capacity is dependent on washer size and
connection type and is shown in the tables below. A time-
delay fuse or circuit breaker is recommended. Installation
of a GFCI is also recommended. Connect to an individual
branch circuit. Do not fuse the neutral or grounding circuit.
■ A separate ground wire is recommended if codes permit.
It is recommended that a qualied electrician determine the
ground path is adequate.
■ Coin-operated washers do not have an emergency stop
switch. A remote emergency stop device must be installed.
The switch must be easily accessable to all users and meet
the requirements of ISO13850-category 0.

NOTES:
■ Connecting these washers to IT power supplies requires
special considerations.
■ 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.
Connection to Washer
These washers were designed for direct wiring into the power
supply. The washer must be electrically grounded in accordance
with 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, and all local codes and
ordinances.
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 ground wire), in a exible metallic conduit. All current
carrying wires must be insulated.
■ Copper wire of appropriate gauge for amperage requirement
(see table below). Stranded wire is recommended. Do not
use aluminum wire.

Equipment Potential Bonding:
In addition to the individual washing machine ground wires
used in conjunction with the power supply wiring, all washers
must be connected with one another using separate insulated
conductors #3 in the illustration below. The rst and last washers
will subsequently be connected to a protective conductor that
completes the loop of the protective ground circuit, #1 in the
illustration.
The external protective connection points that serve for this
purpose (see illustration).
The wire size of the protective conductor #1 must be at least as
large as the insulated conductors #3 being used to interconnect
the washing machines.
