Electric Models Only
All electrically heated dryers must be connected to the
electric service shown on the dryer's data label. The
connecting wires must be properly sized to handle the rated
current.
ELECTRICAL SERVICE SPECIFICATIONS
IMPORTANT: 208 VAC AND 230/240 VAC ARE NOT THE SAME. When ordering,
specify exact voltage.
NOTES: A. When fuses are used they must be dual element, time delay, current
limiting, class RK1 or RK5 ONLY . Calculate/determine correct fuse
value, by applying either local and/or National Electrical Codes to
listed appliance amp draw data.
B. Circuit breakers are thermal-magnetic (industrial) type ONLY . For
others, calculate/verify correct breaker size according to appliance
amp draw rating and type of breaker used.
C. Circuit breakers for 3-phase (3ø) dryers must be 3-pole type.

Grounding
A ground (earth) connection must be provided and installed
in accordance with local, state, and national regulations or
codes of the country of origin. In the absence of these codes,
grounding must conform to applicable requirements of the
National Electrical Code ANSI/NFPA NO. 70-LATEST
EDITION, or in Canada, the installation must conform to
applicable Canada Standards: Canadian Electrical Codes
Parts 1 & 2 CSA C22.1-1990 or LATEST EDITION. The
ground connection may be to a proven earth ground at the
location service panel.

American Dryer Corp.
For added personal safety, when possible, it is suggested
that a separate ground wire (size per local codes) be
connected from the ground connection of the dryer to a
grounded cold water pipe. Do not ground to a gas pipe or hot
water pipe. The grounded cold water pipe must have
metal-to-metal connection all the way to the electrical ground.
If there are any nonmetallic interruptions, such as, a meter,
pump, plastic, rubber, or other insulating connectors, they
must be jumped out with a wire (size per local codes) and
securely clamped to bare metal at both ends.
IMPORTANT: For personal safety and proper operation,
the dryer must be grounded.
Provisions are made for ground connection in each dryer at
the electrical service connection area.
Electrical Connections
A wiring diagram is located behind the control panel for
connection data.
If local codes permit, power to the dryer can be made by the
use of a flexible UL listed power cord/pigtail (wire size must
conform to rating of dryer), or the dryer can be hard wired
directly to the service breaker panel. In both cases, a strain
relief must be installed where the wiring enters the dryer.
For CE Models Only
The means for disconnection from the supply must be
incorporated into wiring having a minimum contact separation
of 3.0 mm in all poles.
Single-Phase (1ø) Wiring Connections / Hookup
The electrical input connections are made into the rear
service box located at the upper right area of the dryer. The
ground connection is made to the copper lug, also provided
in this box. To gain access, the service box cover must be
removed.
Gas and Steam Models Only
120-240V Application

CAUTION: The dryer must be grounded. A ground lug has
been provided for this purpose.
Input connection wiring must be sized properly to handle
the dryer's current draw. This information is printed on the
dryer's data label.
