Additional
installation
requirements
This
dryer
is
suitable
for
mobile
home
installations.
The
installation
must
conform
to
the
Manufactured
Home
Construction
and
Safety
Standard,
Title
24
CFR,
Part
3280
(formerly
the
Federal
Standard
for
Mobile

MH.
Mobile
home
installations
require:
■
Metal exhaust system hardware, which is available for
purchase from your dealer.
■
Special provisions must be made in mobile homes to introduce
outside air into the dryer. The opening (such as a nearby
window) should be at least twice as large as the dryer exhaust
opening.
Electrical Requirements – U.S.A.
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
and
all
local
codes
and
ordinances.
The
National
Electrical
Code
requires
a
4-wire
power
supply
connection
for
homes
built
after
1996,
dryer
circuits
involved
in
remodeling
after
1996,
and
all
mobile
home
installations.

circuit.
■
Do
not

an
extension
cord.
■
If
codes
permit
and
a
separate
ground
wire
is
used,
it
is
recommended
that
a
qualified
electrician
determine
that
the
ground
path
is
adequate.
Electrical Connection
To properly install your dryer, you must determine the type of
electrical connection you will be using and follow the instructions
provided for it here.
■
■
This
dryer
is
manufactured
ready
to
install
with
a
3-wire
electrical
supply
connection.
The
neutral
bond
conductor
is
permanently
connected
to
the
neutral
conductor
(white
wire)
within
the
dryer.
If
the
local
electrical
codes
require
the
use
of
a
ground-fault
circuit
interrupter,
then
a
4
wire
electrical
supply
connection
is
required.
The
neutral
bond
conductor
must
be
removed
from
the
external
ground
connector
(green
screw),
and
secured
under
the
neutral
terminal
(center
or
white
wire)
of
the
terminal
block.
When
the
neutral
bond
conductor
is
secured
under
the
neutral
terminal
(center
or
white
wire)
of
the
terminal
block,
the
dryer
cabinet
is
isolated
from
the
neutral
conductor.
The
green
ground
wire
of
the
4-wire
power
cord
must
be
secured
to
the
dryer
cabinet
with
the
green
ground
screw
.
If
local
codes
do
not
permit
the
connection
of
a
neutral
bond
wire
to
the
neutral
wire,
see
“Optional
3-Wire
Connection.”
■
A 4-wire power supply connection must be used when the
appliance is installed in a location where grounding through
the neutral conductor is prohibited. Grounding through the
neutral conductor is prohibited for (1) new branch-circuit
installations, (2) mobile homes, (3) recreational vehicles, and
(4) areas where local codes prohibit grounding through the
neutral conductors.
If using a power supply cord:
Use a UL listed power supply cord kit marked for use with clothes
dryers. The kit should contain:
■
A UL listed 30 A power supply cord, rated 120/240 V minimum.
The cord should be type SRD or SRDT and be at least 4 ft
(1.22 m) long. The wires that connect to the dryer must end in
ring terminals or spade terminals with upturned ends.
■
A UL listed strain relief.
If your outlet looks like this:
4-wire receptacle
(14-30R)
Then choose a 4-wire power supply cord
with ring or spade terminals and UL listed
strain relief. The 4-wire power supply cord,
at least 4 ft (1.22 m) long, must have four
10-gauge copper wires and match a 4-wire
receptacle of NEMA Type 14-30 R. The
ground wire (ground conductor) may be
either green or bare. The neutral conductor
must be identified by a white cover.
If your outlet looks like this:
3-wire receptacle
(10-30R)
Then choose a 3-wire power supply cord
with ring or spade terminals and UL listed
strain relief. The 3-wire power supply cord,
at least 4 ft (1.22 m) long, must have three
10-gauge copper wires and match a 3-wire
receptacle of NEMA Type 10-30R.
If connecting by direct wire:
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), covered with flexible metallic conduit. All
current-carrying wires must be insulated.
■
10-gauge solid copper wire (do not use aluminum) at least 5 ft
(1.52 m) long.
