(120/208 Volt, 60 Hertz, 3-Wire Installation)
NOTE: The wiring diagram is located behind the
control panel, inside the control cabinet.
Grounding And Wiring Instructions
• Each dryer 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 each dryer.
• Each dryer has its own terminal block that must be
connected to a separate branch, 60 Hertz, single phase
circuit, AC (alternating current) circuit, fused at 30
Amperes (the circuit must be fused on both sides of the
line). ELECTRICAL SERVICE FOR THE DRYER
UNIT SHOULD BE OF MAXIMUM RATED
VOLTAGE LISTED ON THE NAMEPLATE. DO
NOT CONNECT DRYER TO 110, 115, OR 120
VOLT CIRCUIT. Heating elements are available for
field installation in dryer units which are to be
connected to electrical service of different voltage than
that listed on nameplate, such as 208 Volt.
• If branch circuit to dryer unit is fifteen feet (4.50 m) or
less in length, use U.L. (Underwriters Laboratories)
listed No. 10 A.W.G. wire (copper wire only), or as
required by local codes. If over fifteen feet (4.50 m),
use U.L. (Underwriters Laboratories) listed No. 8
A.W.G. wire (copper wire only), or as required by local
codes. Allow sufficient slack in wiring so dryer can be
moved from its normal location when necessary.
• The power cord (pigtail) connection between wall
receptacle and dryer unit terminal block IS NOT
supplied with dryer unit. Type of pigtail and gauge of
wire must conform to local codes and with instructions
mentioned on the following pages.
The method of wiring the dryer unit is optional and
subject to local code requirements. See examples below.
To reduce the risk of fire, electric shock or
personal injury, all wiring and grounding
MUST conform with the latest edition of the
National Electrical Code ANSI/NFPA 70 or the
Canadian Electrical Code, CSA C22.1, and
such local regulations as might apply. It is the
customer’s responsibility to have the wiring
and fuses checked by a qualified electrician
to make sure the laundry room has adequate
electrical power to operate the dryer.
