ELECTRIC DRYER MODELS

ELECTRICAL REQUIREMENTS

OBSERVE ALL GOVERNING CODES AND

ORDINANCES

Electrical Shock Hazard

Electrical ground is required on this appliance.

Improper connection of the equipment-

grounding conductor can result in a risk of

electrical shock.

Check with a qualified electrician if you are in

doubt as to whether the appliance is properly

grounded. Do Not modify the power supply cord

plug. If it will not fit the outlet, have a proper

outlet installed by a qualified electrician.

Do Not use an extension cord with this

appliance. Such use may result in a fire,

electrical shock or other personal injury.

Do Not have a fuse in the neutral or grounding

circuit. A fuse in the neutral or grounding circuit

could result in electrical shock.

Failure to follow these instructions could result in

a fire, electrical shock, or other personal injury.

A three-wire or four-wire, single phase, 120/240-volt, 60-

Hz, AC only, electrical supply (or three-wire or four-wire,

120/208-volt if specified on nameplate) is required on a

separate, 30-ampere circuit, fused on both sides of the

line (time-delay fuse or circuit breaker is recom-

mended). Do Not have a fuse in the neutral or ground

circuit.

THE DRYER MUST BE CONNECTED WITH lo-

GAUGE COPPER WIRE ONLY Aluminum wire must

not be used to avoid potentially unsatisfactory

connections.

Local codes may permit the use of a U.L.-listed,

120/240-volt minimum, 30-ampere, dryer power supply

cord (pigtail). This cord contains three, No.-10 copper

wires and matches a three-wire receptacle of NEMA

Type lo-30R shown in Figure8. Connectors on the dryer

end must be ring terminals or spade terminals with

upturned ends. A

3/4”

U.L.-listed strain relief must be

provided at the point the power supply cord enters

the appliance.

The appliance may be connected directly to the fused

disconnect or circuit breaker box through flexible ar-

mored or non-metallic sheathed copper cable. Allow two

or three feet of slack in the line between the wall and the

appliance so that it can be moved if servicing is ever

necessary. A 3~” U.L.-listed strain relief must be pro-

vided at each end of the power supply cord (at the ap-

pliance and at the junction box). Wire sizes (COPPER

WIRE ONLY) and connections must conform with the

rating of the appliance (30 amperes).

Important: Observe all governing codes and

ordinances.

For mobile home or other four-wire installations, the ap-

pliance wiring must be revised. The appliance cabinet

must not be connected to the neutral terminal, but must

be connected to the grounding wire (green with yellow

stripes) of the power supply cord or cable. (See Page 5

for details.)

When a four-wire receptacle of NEMA Type 14-30R is

used (See Figure 9), a matching 120/240-volt minimum,

30-ampere, U.L.-listed dryer power supply cord (pigtail)

must be used. This cord contains four No.-10 copper

conductors with ring terminals (or spade terminals with

upturned ends) on dryer end terminating in a NEMA

Type 14-30P plug on supply end. The fourth (grounding)

conductor must be identified by a green or green/yellow

cover and the neutral conductor by a white cover. Cord

should be Type SRD or SRDT, with a 3/4” U.L.-listed

strain relief and be at least four feet long. The power

supply cord and strain relief are not provided with the

dryer.

ELECTRICAL CONNECTION:

WARNING:

Improper connection of the equipment

grounding conductor can result in a risk of electrical

shock.

It is the personal responsibility of the customer to con-

tact a qualified installer to assure that the electrical in-

stallation is adequate and is in conformance with the

National Electrical Code ANSVNFPA 70-latest edition,

and all local codes and ordinances.

Disconnect power supply cord from the electrical

supply before making these changes. Failure to do so

may result in personal injury.

GROUNDING INSTRUCTIONS:

This appliance must be connected to a grounded metal,

permanent wiring system; or an equipment-grounding

conductor must be run with the circuit conductors and

connected to the equipment-grounding terminal or lead

on the appliance.

Electrical ground is required on this appliance.

This

appliance is manufactured

with

the neutral terminal

connected to the frame.

If local codes permit connection of the frame

grounding conductor to the neutral wire of the power

supply cord.
