IMPORTANT SAFETY INSTRUCTIONS
Be sure the electrical service is adequate for the model you have
chosen. This information can be found on the serial plate, which
is located on the side of the cabinet and behind the grille.
Be sure the air conditioner is properly grounded. To minimize
shock and fire hazards, proper grounding is important. The power
cord is equipped with a three-prong grounding plug for protection
against shock hazards.
Your air conditioner must be used in a properly grounded wall
receptacle. If the wall receptacle you intend to use is not adequately
grounded or protected by a time delay fuse or circuit breaker,
have a qualified electrician install the proper receptacle.
Ensure the receptacle is accessible after the unit installation.
Do not run air conditioner without side protective cover in place.
This could result in mechanical damage within the air conditioner.
Do not use an extension cord or an adapter plug.
WARNING For your safety
Do not store or use gasoline or other flammable vapors and liquids
in the vicinity of this or any other appliance.
Avoid fire hazard or electric shock. Do not use an extension cord or
an adaptor plug. Do not remove any prong from the power cord.
WARNING Electrical Information
NOTE The power supply cord with
this air conditioner contains a current
detection device designed to reduce
the risk of fire.
Please refer to the section Operation
of Current Device for details.
In the event that the power supply
cord is damaged, it can not be
repaired.It must be replaced with a
cord from the Product Manufacturer.
,
,
Do not, under any
circumstances, cut,
remove, or bypass
the grounding prong.
Power supply cord

and current detection device
Operation of Current Device
The power supply cord contains a current device that senses damage to the power cord. To test your power
supply cord as follows:
1. Plug in the Air Conditioner.
2. The power supply cord will have TWO buttons on the plug head. Press the TEST button, you will notice a
click as the RESET button pops out.
3. Press the RESET button, again you will notice a click as the button engages.
4. The power supply cord is now supplying electricity to the unit. (On some products this it also indicated by
a light on the plug head.)
Do not use this device to turn the unit on or off.
Always make sure the RESET button is pushed in for correct operation.
The power supply must be replaced if it fails reset when either the TEST button is pushed, or it can not be
reset. A new one can be obtained from the product manufacturer.
If power supply cord is damaged, it can not be repaired. It MUST be replaced by one

NORMAL SOUNDS
AIR CONDITIONER FEATURES
Sound of Rushing Air
At the front of the unit, you may
hear the sound of rushing air
being moved by the fan
High Pitched Chatter
High efficiency compressors
may have a high pitched chatter
during the cooling cycle.
Gurgle/Hiss
Gurgling or hissing noise may
be heard due to refrigerant
passing through evaporator
during normal operation.
Pinging or Switching
Droplets of water hitting condenser
during normal operation may cause
pinging or switching sounds.
Before you begin, thoroughly familiarize yourself with the control panel and remote as shown below
and all its functions, then follow the symbol for the functions you desire. The unit can be controlled
by the unit control alone or the remote.

ADDITIONAL THINGS YOU SHOULD KNOW
Now that you have mastered the operating procedure, here are more features in your control that
you should become familiar with.
The Cool circuit has an automatic 3 minutes time delayed start if the unit is turned off and on
quickly. This prevents overheating of the compressor and possible circuit breaker tripping.
The fan will continue to run during this time.
The control will maintain any set temperature within 1 F, between 62 F(17 C) and 86 F(30 C) degrees.
The control is capable of displaying temperature in degrees Fahrenheit or degrees Celsius.
To convert from one to the other, press and hold the Left and Right Temp/Timer buttons at the
same time for 3 seconds.

INSTALLATION INSTRUCTIONS
Your air conditioner is designed to install in standard double hung windows with opening widths of
23 to 36 inches(584mm to 914mm) (See Fig.1).
Lower sash must open sufficiently to allow a clear vertical
opening of 15-1/2 inches (394mm). Side louvers and the rear
of the AC must have clear air space to allow enough airflow
through the condenser, for heat removal. The rear of the unit
must be outdoors, not inside a building or garage.
