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 vapours 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.

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 minute 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 is capable of displaying temperature in degrees Fahrenheit or degrees Celsius.
To convert from one to the other, press and hold the Up and Down Temp/Timer buttons at the
same time, for 3 seconds.
Fresh Air Vent Control(on some models):
Figure 1 (VENT CLOSED) Figure 2 (VENT OPEN)
The Fresh Air Vent allows the air conditioner to:
1. Recirculate air indoors - Vent Closed (See Fig.1)
2. Draw fresh air into the room- Vent Open (see Fig.2)
3. Exchange air from the room and draws fresh air into
the room - Vent and Exhaust Open (see Fig.3)
Figure 3
(VENT & EXHAUST OPEN)
Air Directional Louvers
The 4-way air directional louvers allow you to
direct the air flow up or down(on some models)
and left or right throughout the room as needed.
To adjust the air directional louvers side-to-side,
use the center handles as you move it side-to-side.
