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 vapo rs 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.

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.
To convert from one to the other, press and hold the Left and Right Temp/Timer buttonsat the
same time, for 3 seconds.
Exhaust Control
This Exhaust Control allows the air conditioner to either circulate inside air or exhaust
air to the outside .
The Closed position is used when maximum cooling is desired. It may also be used for air re-
circulation without cooling when the air conditioner is set in any FAN position.
The Open position removes stale air from the room and exhausts it to the outside. Fresh air is
drawn in through normal passages in the home.
4-Way Louvers
The 4-Way air directional louvers allow you to
direct air flow up or down, left or right throughout
the room as needed. To adjust the air directional
louvers side-to-side, use the center handle as you
move it side-to-side.
