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 Electric Code
ANSI/NFPA NO. 70-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 non-metallic 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.
