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 either the back side of the upper control door or left side panel/wall
area behind the control door. The connecting wires must be properly sized to handle the rated
current.
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 local, state, and national
regulations or codes of the country of destination. In the absence of these codes, grounding must conform
to applicable requirements of National Electric Code ANSI/NFPA 70, or in Canada, the installation must
conform to applicable Canada Standards: Canadian Electric Code CSA C22.1. 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 (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.
