PRECAUTIONS

WARNINGS FOR USE

Do not pull or deform the power supply cord. Pulling and misuse of the power supply cord

1

can result in damage to the unit and cause electrical shock.

Be careful not to expose your body directly to the outlet air for a long time. It may affect

2

your physical conditions.

When using the air conditioner for infants, children, elderly, bedridden, or disabled people

3

make sure the room temperature is suitable for those in the room.

Never insert objects into the unit. Inserting objects can result in injury due to the high

4

speed rotation of internal fans.

Ground the air conditioner without fail. Do not connect the grounding wire to gas pipe,

5

water pipe, lightning rod or telephone grounding wire. Incomplete grounding may cause
electric shock.

If anything is abnormal with the air conditioner (ex. a burning smell), stop the operation

6

immediately and turn the circuit breaker OFF.

Follow local rules and regulations for power supply cord cabling. Improper cable

7

connection can cause the power supply cord, plug and the electrical outlet to overheat
and cause fire.

Use only the manufacture-specified power cord for replacement. Replacement should be

8

performed by a qualified technician or a service person.

WARNINGS FOR INSTALLATION / REMOVAL / REPAIR

• Do not attempt to install/remove/repair the unit by yourself. Incorrect work will cause electric
shock, water leak, fire etc. Consult your dealer or other qualified service personnel for the
installation/removal/repair of the unit.

PRECAUTIONS

CAUTIONS FOR USE

Open a window or door periodically to ventilate the room, especially when using gas

1

appliances. Insufficient ventilation may cause oxygen shortage.

Do not operate the buttons with wet hand. It may cause electric shock.

2

For safety, turn the circuit breaker off when not using the unit for an extended period of

3

time.

Check the outdoor unit mounting rack periodically for wear and to make sure it is firmly

4

in place.

Do not put anything on the outdoor unit nor step on it. The object or the person may fall

5

down or drop, causing injury.

This unit is designed for residential use. Do not use for other applications such as in a

6

kennel or greenhouse to raise animals or grow plants.

Do not place a vessel with water on the unit. If water penetrates into the unit, electrical

7

insulations may deteriorate and cause electric shock.

Do not block the air inlets nor outlets of the unit. It may cause insufficient performance

8

or troubles.

Be sure to stop the operation and turn the circuit breaker off before performing any

9

maintenance or cleaning. A fan is rotating inside the unit and you may get injured.

Do not splash or pour water directly on the unit. Water can cause electrical shock or

10

equipment damage.

This appliance is not intended for use by young children or infirm persons without

11

supervision.
Young children should be supervised to ensure that they do not play with the appliance.

CAUTIONS FOR LOCATION / INSTALLATION

• Make sure to connect the air conditioner to power supply of the rated voltage and
frequency.

Use of a power supply with improper voltage and frequency can result in equipment
damage and possible fire.

• Do not install the unit in a place where inflammable gas may leak. It may cause fire.
Install the unit in a place with minimal dust, fumes and moisture in the air.

• Arrange the drain hose to ensure smooth drainage. Insufficient drainage may cause wetting
of the room, furniture etc.

• Make sure a leak breaker or a circuit breaker is installed, depending on the installation
location, to avoid electrical shock.

• Condensation may form on the air outlet if the unit operates continuously in the COOL or
DRY mode when humidity is over 80 percent.

WHEN POWER FAILURE OCCURS

This air conditioner has a memory function to store settings when a power failure occurs.
After power recovery, the unit will automatically re-start in the same settings which were
active before the power failure, except for timer settings.
If the timers were set before a power failure, they will need to be re-set after power recovery.

TIPS ON SAVING ENERGY

Below are some simple ways to save energy when you use your air conditioner.

SET THE CORRECT TEMPERATURE

• Setting the thermostat 1°C higher than the desired temperature in the COOL mode will
save approximately 10 percent in power consumption.

• Setting the temperature lower than necessary during cooling operation will result in
increased power consumption.

BLOCK DIRECT SUNLIGHT AND PREVENT DRAFTS

• Blocking direct sunlight during cooling operation will reduce power consumption.

• Close the windows and doors during cooling opeation.

SET PROPER AIR FLOW DIRECTION TO OBTAIN THE BEST AIR
CIRCULATION

KEEP FILTER CLEAN TO ENSURE THE MOST EFFICIENT OPERATION

MAKE MOST OF THE TIMER OFF FUNCTION

DISCONNECT THE POWER CORD WHEN THE UNIT IS NOT USED FOR AN
EXTENDED PERIOD OF TIME

• The indoor unit still consumes a small amount of power when it is not operating.

• Make sure there is no curtain or other
object between the remote control and
the unit.

• The remote control can send signals
from up to 7 metres away.

6

CAUTION

• Do not allow the signal receiver window to receive strong direct sunlight, since it can
adversely affect its operation. If the signal receiver window is exposed to direct sunlight,
close a curtain to block the light.

• Using a fluorescent lamp with a quick starter in the same room may interfere with
transmission of the signal.

• The unit can be affected by signals transmitted from the remote control of a television,
VCR or other equipment used in the same room.

• Do not leave the remote control in direct sunlight or near a heater. Also, protect the unit
and remote control from moisture and shock which can discolour or damage them.

Make sure that the air filters are

1

not dirty.

Make sure that nothing obstructs

2

the air inlet or outlet.

CAUTION

Check the outdoor mounting rack

3

periodically for wear and to make
sure it is firmly in place.

15

BEFORE CALLING FOR SERVICE

The following conditions do not denote equipment malfunctions

UNIT DOES NOT OPERATE

The unit will not operate if it is turned on
immediately after it is turned off. The unit will not
operate immediately after the mode is changed.
This is to protect the internal mechanisms. Wait 3
minutes before operating the unit.

ODORS

Carpet and furniture odors that entered into the
unit and the air conditioner's inner component
odors at the early stage of installation may be
sent out from the unit.

SWISHING NOISE

The soft, swishing noise is the sound of
the refrigerant flowing inside the unit.

WATER VAPOUR

In the COOL and DRY operation, water
vapour can sometimes be seen at the
air outlet due to the difference between
the room air temperature and the air
discharged by the unit.

CRACKING NOISE

The unit may produce a cracking noise. This sound
is generated by the friction of the front panel and
other components expanding or connecting due to
a temperature change.

If the unit appears to be malfunctioning, check the following points before calling for
service.

IF THE UNIT FAILS TO OPERATE

Check to see if the circuit breaker has tripped or the fuse has blown.

IF THE UNIT FAILS TO COOL THE ROOM EFFECTIVELY

Check the filters. If dirty,
clean them.

Make sure windows and
doors are closed tightly.

Check the outdoor unit to
make sure nothing is blocking
the air inlet or outlet.

A large number of people in
the room can prevent the unit
from achieving the desired
temperature.

Check the thermostat is
proper setting.

Check whether any heat­generating appliances are
operating in the room.

IF THE UNIT FAILS TO RECEIVE THE REMOTE CONTROL SIGNAL

Check whether the remote
control batteries have be­come old and weak.

Try to send the signal again
with the remote control
pointed properly towards the
unit’s signal receiver window.

Check whether the remote
control batteries are in­stalled with the polarities
properly aligned.

Please call for service when OPERATION Lamp and TIMER Lamp on the indicator panel blink.
