IMPORTANT: Do not put your fingers into the air vents

as 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 form on the surface of the horizontal louver causing moisture to drop on to the floor or on furnishings. After a quick restart, the horizontal louver may remain static for approximately 10 seconds. Open angle of the horizontal louver should not be set too small, as COOLING or HEATING performance may be reduced due to too restricted air flow area. Do not move the horizontal louver manually, otherwise the horizontal louver will be out of sync. If this happens, please cease operating, disconnect power for a few seconds and then restart the air conditioner.

Again, press this button for 2 seconds to start/stop vertical louver movement (Left to right). Pressing again for 2 seconds will stop left to right movement at angle when button was pressed.

How the Air Conditioner Works.

Basic operation modes:

AUTO/COOL/DRY/HEAT

When you set the air conditioner in AUTO mode, it will automatically select cooling, heating or fan only operation depending on your required SET temperature and the current room temperature.

The air conditioner will control room temperature automatically to the temperature point you set.

If you feel uncomfortable in the AUTO mode, you can set your desired temperature.

SLEEP OPERATION

When selected, the set temperature will increase (cooling) or decrease (heating) by 1OC per hour for the first 2 hours. Thereafter it keeps this new temperature for 5 hours before switching off. This operation saves energy and improves night time comfort by synchronising with the body’s metabolism.

DRYING OPERATION

The temperature is regulated while dehumidifying by The unit repeating turning on and off the cooling operation or fan only. The fan speed is set to LOW.

HEATING OPERATION

This air conditioner operates on the heat-pump principle, absorbing heat from air outdoors and transferring that heat to the indoor unit. As a result, the operating performance is reduced as outdoor air temperature drops. .

OPTIMAL OPERATION

To achieve optimal performance, please note the following:

Adjust the air flow direction correctly so that it is not torwards people. Adjust the temperature to achieve moderate comfort levels. Excessively low or high temperature waste energy. Improve performance by keeping windows and doors closed. Limit energy usage (run time) by using the TIMER function. Do not put any object near air inlet or air outlet, as the efficiency of the air conditioner may be reduced and may cause the air conditioner to stop running. Inspect the air filters periodically, and clean them when needed.

Special functions

Louver Angle Memory Function:

Within the scope of louver angle safety, the horizontal louver angle is memorised and will return to the position last selected by the user.

If last angle exceeds the believed safe angle, it will memorise as close as possible to last position selected. This will not happen when Turbo or manual control buttons are pressed or after a power interruption.

We strongly suggest that the open angle of the horizontal louver should not be set too small, in case condensed water forms and drips from the horizontal louver.

SELF CLEAN function

Airborne bacteria use the moisture on the indoor heat exchanger (Evaporator) to grow. Regular drying of the exchanger (Evaporator) prevents this growth.

By simply system will automatically manage the process. This cleaning action may be done as frequently as desired. The unit will operate in the following sequence:

FAN mode at Low fan speed—Heating operation with LOW fan speed ---FAN operation--Stop Operation--Turn off.

Note:

Anti-mildew function

When unit is turned off in COOL, DRY,AUTO (Cool) mode, the air conditionerwill continue operating for about 10 minutes with very low airflow. This will help to dry up the condensed water inside the evaporator, and help prevent mildew growth. Under Anti-mildew operation, do not restart the air conditioner until the unit is completely off.

Anto-restart function

After a power interruption such as a blackout, the air conditioner stops but it restarts automatically and performs previous operation when the power supply returns.

choosing the SELF CLEAN function, the

• This function is only activated in COOLING or DRY mode.

• Before activation it is recommended the air conditioner has been running for 30 minutes under cooling operation.

• Pressing the SELF CLEAN or ON/OFF button again during the cleaning cycle will cancel the operation and turn the unit off.
