INSTALLATION INSTRUCTIONS
• WINDOW REQUIREMENTS
These instructions are provided for a standard double hung
window or mobile home double hung window installation in
windows 21.7in (550mm) to 34.6in (880mm). The upper and lower
sash must open sufficiently to allow a clear vertical opening of
12.7in (323mm) from the bottom of the sash to the window stool.
Select a centrally located window on the side of the room that
receives the least direct sunlight. There should be no obstruction to
air flow either inside(i.e curtains) or outside (i.e fence, wall or
bushes).
Read this entire installation manual thoroughly before beginning
the installation.
Make sure you have the necessary tools and other materials for the job. Study the illustrations in these
instructions to become familiar with important details of the installation process.
Read the Use & Care manual to become familiar with the operation of your room air conditioner.
After installing the unit, re-read these instructions to make sure you have completed each step and all parts are
fastened in place for a secure installation.
For best results, perform the installation procedure in the order given. Doing so will minimize the time required
to install the unit.
• BASIC TOOLS NEEDED

the safety instructions that are given following.
• Standard screwdriver
• Carpenter’s level
• Electric drill
• Phillips screwdriver
• 1/4”hex driver
• 1/8”drill bit

• SAFETY INSTRUCTIONS
The receptacle should be an individual branch circuit used only for this air conditioner. Be sure the electrical
service is adequate for the model air conditioner you have chosen. The complete electrical rating of your air
conditioner is stated on the name plate located at the unit’s side. Be sure the plug receptacle is close enough
for the power cord to reach it.
Your air conditioner must be plugged into a properly grounded and polarzied three prong receptacle. Do not
use an adapter plug. If the wall receptacle you intend to use will not accept a three-prong plug, or if you are not
sure the outlet is adequately grounded or protected by a fuse or circuit breaker, have a qualified electrician
install the proper oulet according to the National Electric Code and applicable local code.
WARNING :
An extension cord must not be used with your air conditioner!
To minimize shock and fire hazards, proper grounding is important. For your safety and
protection,this air conditioner is equipped with a special three-prong grounding plug on the service cord.
WARNING :
Do not, under any circumstances, cut or remove the grounding prong on the plug. To do so will create a
shock hazard.

•CHANGING AIR FLOW DIRECTION
Air flow deflectors divert air from center flow to left or right.
Adjust deflectors for desired air flow pattern.
•AIR FLOW AROUND UNIT
Check in door grill and outdoor louvers for air flow obstructions. Do not block air flow to and from unit. The
outdoor coil should be checked and periodically cleaned for debris that may collect and block unit air flow.
If air flow is obstructed or deflected back into unit, the compressor may cycle on and off rapidly, causing
early compressor failure.
