• Be sure that placement of the unit allows adequate condensate drainage.
• Do not install near a doorway.
• Ensure that the spaces indicated by the arrows is from
the wall, ceiling or other obstacles (See minimum clearances required in Figure 1.)
• Noise prevention should be considered when installing
the unit.
• Do not place the unit closer than 3 ft. (1m) to a TV or
radio.
• Consideration should be given to the distance from furniture, curtains, or other obstructions that will interfere with

Codes & Regulations
This product is designed and manufactured to comply with
national codes. Installation in accordance with such codes and/
or prevailing local codes/regulations is the responsibility of the
installer. The manufacturer assumes no responsibility for equipment installed in violation of any codes or regulations.
The United States Environmental Protection Agency (EPA)
has issued various regulations regarding the introduction and disposal of refrigerants. Failure to follow these
regulations may harm the environment and can lead to
the imposition of substantial fines. Should you have any
questions please contact the local office of the EPA.
Installation Considerations
To ensure that the unit operates safely and efficiently, it must
be installed, operated, and maintained according to these
installation and operating instructions and all local codes and
ordinances, or, in their absence, with the latest edition of the
National Electrical Code. The proper installation of this unit is
described in the following sections. Following the steps in the
order presented should ensure proper installation.

INDOOR UNIT
T o avoid prop erty damage, personal inj ury or death due to
electrical shock, do not use an ext ension cord wit h this unit.
• Do not expose unit to excessive heat.
• Select a location where there are no obstructions in front
or the sides of the unit.
• Locate the outdoor unit in a location that will not obstruct discharge air from the condenser.
• Do not install outdoor unit in a corrosive environment.
• Keep the clearances from the wall or other obstacles as
indicated by the arrows on Figure 2.
• Do not place animals or plants in the path of the air inlet
or outlet.

• Select a location where noise, vibration and hot discharged air will not be an issue.
• Do not install where high frequency equipment is used
(wireless equipment, welding machine, medical facility)
as it may interfere with the unit’s operation.
Rooftop Installations
If it is necessary to install the outdoor unit on a roof structure,
ensure the roof structure can support the weight and that proper
consideration is given to the weather-tight integrity of the roof.
Since the unit can vibrate during operation, sound vibration
transmission should be considered when installing the unit.
Vibration absorbing pads or springs can be installed between
the condensing unit legs or frame and the roof mounting assembly to reduce noise vibration.

Indoor Unit Installation
Installation of Mounting Bracket
1. Install the mounting bracket horizontally and securely to
the wall, allowing room for access on either side of the
unit.
2 If the wall is constructed of brick, concrete or similar
material, drill eight (8) 3/16” (5 mm) diameter holes in the
wall. Insert the clip anchor for appropriate mounting
screws.
3. Install the mounting bracket on the wall with eight (8)
type “A” screws.
3
NOTE: Install the mounting bracket and drill the holes in the
wall according to the wall structure and the corresponding mounting points on the mounting bracket. (The
mounting brackets vary according to the model.)
