WARNING: 208 VAC and 230/240 VOLTS ARE NOT THE SAME. Any damage done to dryer
components due to improper voltage connection will automatically 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 ELECTRIC CODE (ANSI/NFPA NO.70-1984). 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. The grounded cold water pipe must have metal to metal connection all
the way to electrical ground. If there are any nonmetallic interruptions, such as, a meter, pump,
plastic, rubber, or other insulating. Connectors, they must be jumped 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.
4. Electrical Connections
A wire diagram is located on the back side of the control (service) door for connection data.
The only electrical input connections to the dryer are the 3-phase (3Ø) power leads (L1, L2,
L3, and sometimes Neutral) and ground.
