ELECTRICAL WARNINGS

•

Only use the speciﬁed power cord. If the power cord is damaged, it must be replaced by the

manufacturer or certiﬁed service agent.

•

Keep power plug clean. Remove any dust or grime that accumulates on or around the plug. Dirty

plugs can cause fire or electric shock.

•Do not

pull power cord to unplug unit. Hold the plug ﬁrmly and pull it from the outlet. Pulling

directly on the cord can damage it, which can lead to ﬁre or electric shock.

•Do not

use an extension cord, manually extend the power cord, or connect other appliances to

the same outlet as the air conditioner. Poor electrical connections, poor insulation, and insufﬁcient

voltage can cause fire.

CLEANING AND MAINTENANCE WARNINGS

•

Turn off the device and pull the plug before cleaning. Failure to do so can cause electrical shock.

•Do not

clean the air conditioner with excessive amounts of water.

•Do not

clean the air conditioner with combustible cleaning agents. Combustible cleaning agents

can cause fire or deformation.

CAUTION

•

If the air conditioner is used together with burners or other heating devices, thoroughly ventilate

the room to avoid oxygen deﬁciency.

•

Turn off the air conditioner and unplug the unit if you are not going to use it for a long time.

•

Turn off and unplug the unit during storms.

•

Make sure that water condensation can drain unhindered from the unit.

•Do not

operate the air conditioner with wet hands. This may cause electric shock.

•Do not

use device for any other purpose than its intended use.

•Do not

climb onto or place objects on top of the outdoor unit.

•Do not

allow the air conditioner to operate for long periods of time with doors or windows open,

or if the humidity is very high.

Achieving Optimal Performance

Optimal performance for the COOL, HEAT, and DRY modes can be achieved in the following

temperature ranges. When your air conditioner is used outside of these ranges, certain safety

protection features will activate and cause the unit to perform less than optimally.

•Limit energy usage by using TIMER ON and TIMER OFF functions.

•Do not block air inlets or outlets.

•Regularly inspect and clean air filters.

FOR OUTDOOR UNITS

WITH AUXILIARY

ELECTRIC HEATER

Inverter Split Type

Fixed-speed Type

When outside

temperature is below 0°C

(32°F ), we strongly

recommend keeping the

unit plugged in at all

time to ensure smooth

ongoing performance.

NOTE ON ILLUSTRATIONS

Illustrations in this manual are for explanatory purposes. The actual shape of your indoor unit may be

slightly different. The actual shape shall prevail.

For a detailed explanation of each function,

refer to the Remote Control Manual.

condensed water and prevent mildew growth.

Unit

Speciﬁcations

and Features

•Wireless Control (some units)

Wireless control allows you to control your air

conditioner using your mobile phone and a

Wireless connection.

•Louver Angle Memory(some units)

When turning on your unit, the louver will

automatically resume its former angle.

•Refrigerant Leakage Detection (some

units)

The indoor unit will automatically display “EC”

when it detects refrigerant leakage.

For a detailed explanation of your unit’s

Setting vertical angle of air ﬂow

While the unit is on, use the SWING/DIRECT

button to set the direction (vertical angle) of

airﬂow.

Press the SWING/DIRECT button once to

activate the louver. Each time you press

the button, it will adjust the louver by 6°.

Press the button until the direction you

prefer is reached.

To make the louver swing up and down

continuously, press and hold the SWING/

DIRECT button for 3 seconds. Press it

again to stop the automatic function.

The horizontal angle of the airflow must be set

manually. Grip the deflector rod (See Fig.B)

and manually adjust it to your preferred direction.

For some units, the horizontal angle of the airflow

can be set by remote control. please refer to the

Remote Control Manual.

NOTE ON LOUVER ANGLES

When using COOL or DRY mode, do not set

louver at too vertical an angle for long periods

of time. This can cause water to condense on

the louver blade, which will drop on your ﬂoor

or furnishings. (See Fig.A)

When using COOL or HEAT mode, setting the

louver at too vertical an angle can reduce the

performance of the unit due to restricted air

ﬂow.

Do not move louver by hand. This will cause the

louver to become out of sync. If this occurs, turn

off the unit and unplug it for a few seconds,

then restart the unit. This will reset the louver.

CAUTION

Do not put your fingers in or near the blower

and suction side of the unit. The high-speed

fan inside the unit may cause injury.
