Never place food, precision instruments,

plants, animals, paint, etc. on the unit.

Do not expose plants or animals directly

to the air flow.

Never clean the air conditioner with water.

Never use combustible cleaning agents

as these could cause a fire or deformation.

Never place any burning objects close to

the device if they could be directly affected

by the emitted air.

Never step onto the outdoor device and

explosion.

Never allow the air conditioner to run for

too long with the doors or windows open,

or if the humidity is very high.

If the air conditioner is to be used in

conjunction with other heaters, the air

should be refreshed periodically, otherwise

there is a risk of lack of oxygen.

Always switch off the air conditioner switch

off disconnect during a storm. Electrical

parts may get damaged.

Check that the drainage line is correctly

connected. If not, water will escape.

Check that the condensation water can run

off unhindered. It may cause water damage

if the condensation water cannot run off

properly.

The air conditioner must be earthed in

accordance with the local codes.

For electrical safety purposes we

OPERATING INSTRUCTIONS

Special functions

This air conditioner is equipped with ionizer or Plasma Dust Collector(Depending on specific

configuration of the model). With the anions generated by Ionizer, the air circulation of the air

conditioner fills the room with refreshing, natural and healthy air. The Plasma Dust Collector

generates a high voltage ionization zone, through which the air is converted to plasma. Inside

the air most of the dust, smoke, and pollen particles are captured by the electrostatic filter.

CLEAN AIR function(optional):

Vertical swing function(optional):

After the air conditioner starts up, users can control the vertical louver swing by the remote

controller.

SELF CLEAN function(optional):

Function used after the Shut Down of cooling operation to clean the Evaporator

and keep it fresh for the next operation.

The unit will operate according to following sequence : FAN ONLY mode at Low fan

speed--Heating operation with LOW fan speed(applicable to cooling & heating models

only) ---FAN ONLY operation--Stop Operation---Turn off.

Note:

This function is only available under COOL(AUTO COOL, FORCED COOL) and DRY mode

operation for about half an hour. Once the Self Clean function is activated, all TIMER

settings will be canceled.

During Self Clean operation, pressing the SELF CLEAN button on the remote controller

again will stop operation and turn off the unit automatically.

Refrigerant Leakage Detection(optional):

With this new technology, the display area will appear EC and the indication lamps

continue

flashing when the outdoor unit detects refrigerant leakage.

Louver Angle Memory Function(optional):

Within the scope of safety angle, it will memorize the open angle of horizontal louver.

If it exceeds, it will memorize the boundry of safety angle. In

the following circumstances,

it will return to standard angle: 1) pressing the manual switch, 2)unplug and then plug in

the machine.

We strongly suggest that the open angle of the horizontal louver should not be

set too small, in case the condensed water forms and drips from the horizontal louver.

Displays the special functions in the following ways(for some models only):

Displays for three seconds when Timer ON, Fresh, Swing, Turbo

or Silence feature is activated.

Displays for three seconds when Timer OFF is set.

Displays for three seconds when Fresh, Swing, Turbo or Silence

feature is cancelled.

Displays under defrosting operation.

Displays when anti-cold air feature is

OPERATING INSTRUCTIONS

Airflow direction control

Adjusting the air flow direction improperly can cause

discomfort or cause uneven room temperatures

Adjust the horizontal/vertical louver using the remote

controller. For some models, the vertical louver can

only be adjusted manually.

To set the horizontal/vertical air flow direction

Perform this function while the unit is in operation.

Use the remote controller to adjust the air flow direction.

The vertical/horizontal louver changes 6 degree in angle

for each press, or swings up and down automatically.

Please refer to the REMOTE CONTROLLER OPERATION

MANUAL for details.

For some models, the vertical louver can only be adjusted

manually. Move the deflector rod manually to adjust the air

flow in the direction you prefer.

IMPORTANT:Do not put your fingers into the louver area.

The

high-speed fan inside may cause injury.

Do not operate the air conditioner for long periods with

the air flow direction set downward in cooling or

dehumidifying mode. Otherwise, condensation may

occur on the surface of the horizontal louver causing

moisture to drop on to the floor or on furnishings.

When the air conditioner is started immediately after it

was stopped, the horizontal louver might not move for

approximately 10 seconds.

Open angle of the horizontal louver should not be set

too small, as COOLING or HEATING performance may

be impaired due to too restricted air flow area.

Do not move the horizontal louver manually, otherwise

the horizontal louver will be out of sync. Please cease

operating, unplug power for a few seconds,then restart

the air conditioner.

Do not operate unit with horizontal louver in closed

position.

CAUTION
