Electrical Requirements
It is your responsibility
[]
To contact a qualified 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, 50/60 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 qualified 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: 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 flexible 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.

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 first and last washers
will subsequently
be connected
to a protective conductor
that
completes
the loop of the protective ground circuit, #1 in the
illustration.
There are external
protective
connection
points
that serve for this
purpose,
see illustration.
The wire size of the protective
conductor
#1 must be at {east as
large as the insulated conductors
#3 being used to interconnect the
washing
machines.
