Electrical Requirements
For Your Air Conditioner
ELECTRICAL REQUIREMENTS ARE DIFFERENT
FOR THE TWO MODELS SHOWN ON THE
COVER, DEPENDING ON THE AMPERE RATING
OF YOUR UNIT. THE NUMBER OF AMPERES IS
PRINTED ON THE SERIAL PLATE, ATTACHED TO
THE FRONT OF THE UNIT, BEHIND THE FRONT
PANEL (SEE PAGE 2).
OBSERVE ALL LOCAL GOVERNING CODES
AND ORDINANCES
Do not, under any circumstances, remove the
power supply cord ground prong.
RECEPTACLE WIRING
RECEPTACLE WIRING should be at least as
large as 14 gauge. Use copper wire only. It is the
personal responsibility and obligation of the
customer to provide proper and adequate
receptacle wiring installed by a qualified electri-
cian. OBSERVE NATIONAL ELECTRICAL
CODE AND ALL LOCAL GOVERNING
CODES AND ORDINANCES.
Electrical Requirements
A 115 volt (103.5 min., 126.5 max.) 60 hertz AC
only, 15 ampere fused electrical supply is required
(time delay fuse or time delay circuit breaker re-
quired). It is recommended that a separate circuit,
serving only this appliance, be provided for models
with serial plate amperes up through 7.5. A separate
circuit is required for models with serial plate amperes
of 7.6 through 72.0. Do not use an extension cord.
Electrical Connection
Electrical Ground is Required on this Appliance
RECOMMENDED GROUNDING METHOD
For your personal safety, this appliance must be
grounded. This appliance is equipped with a
power supply cord having a 3-prong grounding
plug. To minimize possible shock hazard, the
cord must be plugged into a mating 3-prong
grounding type wall receptacle, grounded in
accordance with the National Electrical Code
and local codes and ordinances. If a mating wall
receptacle is not available, it is the personal
responsibility and obligation of the customer to
have a properly grounded 3-prong wall receptacle
installed by a qualified electrician. See Figure 1.

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.
