2) Electric Models ONLY
ALL electrically heated dryers must be connected to the electric service shown on the dryer’s
data label, which is affixed to the upper left area of the inner back panel. The connecting wires
must be properly sized to handle the rated current.
NOTE: Electrically heated service (amperage) specifications/requirements are not available at the time
of printing. Contact factory for update.
NOTE: Component failure due to improper voltage application will VOID THE WARRANTY.
3. Grounding
A ground (earth) connection must be provided and installed in accordance with state and local codes. 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.
For added personal safety, when possible, it is suggested that a separate ground wire (no. 18 minimum) 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 no. 4 copper wire 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.
4. Electrical Connections
A wiring diagram is located inside the rear electric box.
NOTE: A CIRCUIT SERVICING EACH DRYER
MUST BE PROVIDED.
The electrical input connections on ALL dryers are made
into the rear service box located at the upper right area
of the dryer.
