1. Safety Precautions

Before installing the unit, make sure you read all the

“Safety Precautions”.

The “Safety Precautions” provide very important

points regarding safety. Make sure you follow them.

Please report to or take consent by the supply

authority before connection to the system.

Symbols used in the text

Warning: Describes precautions that should be observed to prevent danger of injury or death to the user.

Caution: Describes precautions that should be observed to prevent damage to the unit.

Warning:

• These appliances are not accessible to the general public.

• The unit must not be installed by the user. Ask the dealer or an authorized company to install the unit. If the unit is installed improperly, water leakage, electric shock or fire may result.

• Do not stand on, or place any items on the unit.

• Do not splash water over the unit and do not touch the unit with wet hands. An electric shock may result.

• Do not spray combustible gas close to the unit. Fire may result.

• Do not place a gas heater or any other open-flame appliance where it will be exposed to the air discharged from the unit. Incomplete combustion may result.

• Do not remove the front panel or the fan guard from the outdoor unit when it is running.

• Never repair the unit or transfer it to another site by yourself.

• When you notice exceptionally abnormal noise or vibration, stop operation, turn off the power switch, and contact your dealer.

• Never insert fingers, sticks etc. into the air inlets or outlets.

• If you detect odd smells, stop using the unit, turn off the power switch and consult your dealer. Otherwise, a breakdown, electric shock or fire may result.

• This air conditioner is NOT intended for use by children or infirm persons without supervision.

Caution:

• Do not use any sharp object to push the buttons, as this may damage the remote controller. Never block or cover the indoor or outdoor unit’s air inlets or outlets

•

• Never wipe the remote controller with benzene, thinner chemical rags, etc.

• Do not operate the unit for a long time in high humidity, e.g. leaving a door or window open. In the cool mode, if the unit is operated in a room with high humidity (80% RH or more) for a long time, water condensed in the air conditioner may drop and wet or damage furniture, etc.

Symbols used in the illustrations

: Indicates a part which must be grounded.

• Young children must be supervised to ensure that they do not play with the air conditioner.

• If the refrigeration gas blows out or leaks, stop the operation of the air conditioner, thoroughly ventilate the room, and contact your dealer.

• This appliance is not intended for use by persons (including children) with reduced physical, sensory or mental capabilities, or lack of experience and knowledge, unless they have been given supervision or instruction concerning use of the appliance by a person responsible for their safety.

• When installing or relocating, or servicing the air conditioner, use

only the specified refrigerant (R410A) to charge the refrigerant lines. Do not mix it with any other refrigerant and do not allow air to remain in the lines. If air is mixed with the refrigerant, then it can be the cause of abnormal high pressure in the refrigerant line, and may result in an explosion and other hazards. The use of any refrigerant other than that specified for the system will cause mechanical failure or system malfunction or unit breakdown. In the worst case, this could lead to a serious impediment to securing product safety.

• Do not touch the upper air outlet vane or the lower air outlet damper during operation. Otherwise, condensation may form and

the unit may stop operating.

Disposing of the unit

When you need to dispose of the unit, consult your dealer.

When using the wireless remote controller, point it towards the receiver on the indoor unit. If the remote controller is operated within approximately 2 minutes after power is supplied

to the indoor unit, the indoor unit may beep twice as the unit is performing the initial automatic check.

The indoor unit beeps to confirm that the signal transmitted from the remote controller has

been received. Signals can be received up to approximately 7 meters in a direct line from the indoor unit in an area 45° to the left and right of the unit. However, illumination such as fluorescent lights and strong light can affect the ability of the indoor unit to receive signals.

If the operation lamp near the receiver on the indoor unit is flashing, the unit needs to be

inspected. Consult your dealer for service.

Handle the remote controller carefully! Do not drop the remote controller or subject it to

strong shocks. In addition, do not get the remote controller wet or leave it in a location with high humidity.

To avoid misplacing the remote controller, install the holder included with the remote

controller on a wall and be sure to always place the remote controller in the holder after use.
