ALTERNATE GROUNDING METHOD
If changing and properly grounding the wall
receptacle is impossible and where local codes
permit (consult your electrical inspector), a
temporary adapter may be plugged into the
existing 2-prong wall receptacle to mate with the
3-prong power supply cord. See Figure 2. THIS,
HOWEVER, IS NOT RECOMMENDED.
If this is done, you must connect the grounded
eyelet on the adapter to the wall receptacle
cover plate screw and from this same screw, you
must connect a separate copper ground wire
(#14 minimum) to a grounded cold water pipe.*
See Figure 2. Do not ground to a gas supply
pipe. Do not connect to electrical supply until
appliance is permanently grounded.

ELECTRICAL
REQUIREMENTS
I
For 230 volt and 230/208 volt models with serial
plate amperes up through 12.0
Refer to Chart B for specific wiring and receptacle
information to be used.
OBSERVE ALL LOCAL GOVERNING CODES
AND ORDINANCES.
Do not, under any circumstances, remove the
power supply cord ground plug.
ELECTRICAL GROUND IS REQUIRED ON
THIS APPLIANCE.
A three-wire, single-phase 60 hertz AC only
electrical supply is required.
A separate electrical supply is required on a
separately fused circuit. Do not fuse ground-
neutral.
See Chart B for receptacle voltage require-
ments, proper fuse size, wire and wiring con-
nections which must conform with rating of
the appliance. Do not use an extension cord.
