Installation
Installation Requirements
Air conditioner must be properly installed for safe
operation. Refer to Installation Guide included with unit for
detailed installation instructions. Small and mini chassis
air conditioners are designed for window installation only,
using installation kit provided with unit. Large chassis air
conditioners may be installed in a window, using the
window mounting kit provided, or can be in installed
through an outside wall.
NOTE: Consumer assumes all risk for through wall
installations.
Before beginning any installation:
• Carefully read all instructions for the installation. Make
sure each step or procedure is understood and any
special considerations are taken into account.
• Assemble all tools, hardware, and supplies needed to
complete the installation. Some items may need to be
purchased locally. Make sure everything needed to
install air conditioner is on hand before starting.
• After deciding where to install unit, closely look location
over—both inside and outside the home. Note any
potential obstacles or problems that might be
encountered. Choose a more suitable location if
necessary.
Electrical Requirements
!
WARNING
To avoid risk of personal injury or death due to
electrical shock:
• Electrical grounding is required on all air
conditioners.
• Check with a qualified electrician if you are not sure
intended electrical outlet is properly grounded.
• DO NOT ground to gas line.
• DO NOT use cold water pipe for ground if pipe is
interrupted by plastic, non-metallic gaskets, or
other insulating (non-conducting) materials.
• DO NOT modify plug on power cord. If plug does
not fit electrical outlet, have a matching outlet
installed by a qualified electrician.
• DO NOT have a fuse in the neutral or ground
circuit. A fuse in the neutral or ground circuit could
result in an electrical shock.
• DO NOT use an extension cord with this device.
• DO NOT use an adapter plug with this device.
• Observe all local codes and ordinances.
For safety, air conditioner must be grounded. All air
conditioners have a power supply cord with a three-prong
grounding plug. To minimize possible electrical shock
hazard, the power cord must only be plugged into a
matching grounding wall receptacle in accordance with
the National Electrical Code (and any applicable local
codes and ordinances). If an appropriate grounding-type
wall receptacle is not available, have a properly grounded
wall receptacle installed by a qualified electrician.
If codes permit, and a separate grounding wire is used,
have a qualified electrician determine if grounding path is
adequate and uninterrupted by plastic, non-metallic
gaskets, or other insulating (non-conductive) materials.
Electrical Connection
Devices covered in this manual require a 60Hz supply.
Refer to name plate on air conditioner for exact voltage
requirements. Voltage requirements can also be
determined by the type of plug on air conditioner. See
following table (Table 1).

An appropriate wall receptacle (electrical outlet) must be
within reach of air conditioner power supply cord. Do not
use an extension cord. If power supply cord does not
reach intended wall receptacle, have a qualified electrician
install or move an appropriate receptacle closer to unit.
Do not use an adapter plug. If intended wall receptacle
does not match plug on air conditioner, have a qualified
electrician replace receptacle with correct type.
Receptacle Wiring
Receptacle wiring must be of adequate size for unit. Refer
to unit identification plate for exact power requirements.
Power requirements can also be determined by the type
of plug on unit (see Table 1). Minimum size of wiring,
based on power requirements, is:
Units up to 20 amps:
20–30 amp units:
Use copper wire only. It is owner's responsibility to
provide proper and adequate receptacle wiring that
conforms to all applicable codes. All wiring should be
installed by a qualified electrician.
