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.
