POINTS FOR USING AIR CONDITIONER
NOTE: This User s Manual provides specific
operating instructions for your model. Use the
room air conditioner only as instructed in this
User s Manual. These instructions are not
meant to cover every possible condition and
situation that may occur. Common sense and
caution must be practiced when installing,
operating, and maintaining any appliance.

IMPORTANT SAFETY INSTRUCTIONS
All wiring must comply with local and national electrical codes and be installed
by a qualified electrician.
Never insert your fingers or any foreign objects into the air outlet.
Take special care to warn children of these dangers.
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 with outside protective cover in place. This could result
in mechanical damage within the air conditioner.
The capacity of the room air conditioner must fit the room size for efficient and
satisfactory operation.
Install the room air conditioner on the shady side of your room.
Do not block air flow inside with blinds, curtains or furniture; or outside with shrubs,
enclosures, or other buildings.
Keep blinds and drapes in other windows closed during the sunniest part of the
day.
Clean the air filter as recommended in the section Care and Cleaning .
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.

THERMOSTAT
COOLER
To set the desired room temperature, rotate the
thermostat switch to the desired setting. After
the set temperature is achieved the thermostat
will automatically start and stop the compressor
in order to maintain the desired set temperature.
Rotate the thermostat selector clockwise for
higher cool settings. Higher cool settings will
provide lower room temperature. Rotate the
thermostat selector counter clockwise for lower
cool settings. Lower cool settings will provide
higher room temperature.
Thermostat
The thermostat is used to set the desired room
temperature when the unit is being operated in
the COOL MODE.
NOTE:
COOLER
During the cooling operation of the unit, when the
thermostat knob is rotated clockwise, allow at least three
minutes before turning back the knob to the
direction. Otherwise the fuse may blow due to an overload
of the unit.
AUTO SWING
OFF ON
AUTO SWING
Horizontal air flow adjustment (automatically)
When the AUTO SWING switch is turned to ON
position, the vertical louvers automatically oscillate
right and left sweeping the cold air alternately to
obtain comfortable cooling. The vertical louvers may
be stopped at any position when the AUTO SWING
switch is turned OFF .

Vertical air flow adjustment (manually)
To adjust vertical air flow direction, adjust any one of
the horizontal louver blades. When turning up or down
the horizontal louver blades, always keep horizontality
the top or bottom blades. This can effectively prevent
water drops condensed on the front panel of the unit.
Vent Control
The vent control is located above the control knobs. The operation method is different
on different models (see the following figures).
For maximum cooling efficiency, CLOSE the vent. This will allow internal air circulation.
OPEN the vent to discharge stale air.
CLOSE VENT OPEN
To open the vent, pull the lever toward you
To close it, push it in.
To open the vent, set the lever to the right position
To close it, set the lever in the left position.
CLOSE OPEN
NOTE: The VENTILATION LEVER should normally be kept in the CLOSED position during
cooling for maximum cooling effect. The "OPEN" position is used only for ventilation.
CARE AND CLEANING
Clean your air conditioner occasionally to keep it looking new. Be sure to unplug
the unit before cleaning to prevent chock or fire hazards.
CAUTION
Air Filter Cleaning
The air filter should be checked at least once a
month to see if cleaning is necessary. Trapped
particles in the filter can build up and cause an
accumulation of frost on the cooling coils.

Hold the slot under the front panel, then uplift it onwards, and remove the front panel.
Pinch the handle under the air filter and make the air filter arched, remove it from the
underside to upside.
Wash the filter using liquid dishwashing detergent and warm water. Rinse filter thoroughly.
Gently shake excess water from the filter. Be sure the filter is thoroughly dry before
replacing.
Or, instead of washing you may vacuum the filter clean.
Never use hot waterNote:
over 40 C(104 F) to clean the air filter. Never attempt to
operate the unit without the air filter.
CARE AND CLEANING(CONTINUED)
Never use water over 50 C, alcohol, gasoline, acid, solvent or brush to
clean the front panel as this will damage the surface of the part.
NOTE:
If you plan to store the air conditioner during the winter, remove it carefully from the
window according to the installation instructions. Cover it with plastic or return it to
the original carton.
Winter Storage
Never use harsh cleaners, wax or polish on the cabinet front.
Be sure to wring excess water from the cloth before wiping around the controls.
Excess water in or around the controls may cause damage to the air conditioner.
Plug in air conditioner.
Cabinet Cleaning
Be sure to unplug the air conditioner to prevent shock or fire hazard. The cabinet
and front may be dusted with an oil-free cloth or washed with a cloth dampened in
a solution of warm water and mild liquid dishwashing detergent. Rinse thoroughly
and wipe dry.
&Select The Best Location
Install the unit at a place having sufficient strength to support the unit securely.
For maximum efficiency, install the air conditioner on a side of a house or building
which favors more shade than direct sunlight.
Provide sufficient clearance or space around the air inlet and air outlet so that air
flow will not be obstructed, following figures give detailed requirements.
Only trained and qualified service personnel should install, repair or service air
conditioning equipment. Users should not install the air conditioner by themselves.

To meet different requirement of different type of air
conditioner, there are two kinds of methods for your
choice to treat the condensed water. You can choose
back drainage or non-drainage. See the following
procedures to perform back drainage:
1. Fit the seal onto the drain joint (which provided with
your air conditioner accessory).
2. Remove the rubber plug from the back of the unit.
3. Attach the drain joint to the back of the cabinet
where you remove the plug and rotate 90 to securely
assemble them.
4. Connect the drain joint with a extension drain hose
