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 .

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.
