** Dryers are built 4-wire. Customer must contact factory to special order 3-wire.
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.

208 VAC AND 230/240 VAC ARE NOT THE SAME. When ordering, specify exact voltage.
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.
Circuit breakers are thermal-magnetic (industrial) motor curve type ONLY. For others, calculate/verify
correct breaker size according to appliance amp draw rating and type of breaker used.
Circuit breakers for 3-phase (3Ø) dryers must be 3-pole type.
