SAFETY PRECAUTION

Please read the “Safety Precaution” carefully before operating the unit to ensure correct usage of the unit. ●

Pay special attention to signs of “ ●

!

Warning” and “

!

Caution”. The “Warning” section contains matters which,

if not observed strictly, may cause death or serious injury. The “Caution” section contains matters which may

result in serious consequences if not observed properly. Please observe all instructions strictly to ensure safety.

The sign indicate the following meanings.

●

Make sure to connect earth line.

The sign in the ﬁ gure indicates prohibition.

Indicates the instructions that must be followed.

Please keep this manual after reading.

●

PRECAUTIONS DURING INSTALLATION

Do not reconstruct the unit. ●

Water leakage, fault, short circuit or ﬁ re may occur if you reconstruct the unit by

yourself.

Please ask your sales agent or qualiﬁ ed technician for the installation of your unit.

●

Water leakage, short circuit or ﬁ re may occur if you install the unit by yourself.

Please use earth line.

●

Do not place the earth line near water or gas pipes, lightning-conductor, or the

earth line of telephone. Improper installation of earth line may cause electric

shock.

Be sure to use the speciﬁ ed piping set for R410A. Otherwise, this may result in

●

broken copper pipes or faults.

A circuit breaker should be installed depending on the mounting site of the unit.

●

Without a circuit breaker, the danger of electric shock exists.

Do not install near location where there is ﬂ ammable gas. The outdoor unit may

●

catch ﬁ re if ﬂ ammable gas leaks around it.

Please ensure smooth ﬂ ow of water when installing the drain hose.

During thunder storm, disconnect and turn off the circuit breaker.

●

Do not use any conductor as fuse wire, this could cause fatal accident. ●

PRECAUTIONS DURING SHIFTING OR MAINTENANCE

Should abnormal situation arises (like burning smell), please stop operating the ●

unit and turn off the circuit breaker. Contact your agent. Fault, short circuit or ﬁ re

may occur if you continue to operate the unit under abnormal situation.

Please contact your agent for maintenance. Improper self maintenance may cause

●

electric shock and ﬁ re.

Please contact your agent if you need to remove and reinstall the unit. Electric

●

PRECAUTIONS DURING OPERATION

Do not attempt to operate the unit with wet hands, this could cause fatal●

accident.

When operating the unit with burning equipments, regularly v

entilate the

●

room to avoid oxygen insufﬁ ciency.

Do not direct the cool air coming out from the air-conditioner panel to face●

household heating apparatus as this may affect the working of apparatus

such as the electric kettle, oven etc.

Do not use any aerosol or hair sprays near the indoor unit.

This chemical

●

can adhere on heat exchanger ﬁ n and blocked the evaporation water ﬂ ow to

drain pan. The water will drop on tangential fan and cause water splashing

out from indoor unit.

Please ensure that outdoor mounting frame is always stable, ﬁ rm and ●

without defect. If not, the outdoor unit may collapse and cause danger.

Do not splash or direct water to the body of the unit when cleaning it as this●

may cause short circuit.

When operating the unit with the door and windows opened, (the room humidity is always above ●

80%) and with the air deﬂ ector facing down or moving automatically for a long period of time, water

will condense on the air deﬂ ector and drips down occasionally. This will wet your furniture. Therefore,

do not operate under such condition for a long time.

If the amount of heat in the room is above the cooling or heating capability of the unit (for example: ●

more people entering the room, using heating equipments and etc.), the preset room temperature

cannot be achieved.

This appliance is not intended for use by young children or inﬁ rm persons unless they have

been

●

adequately supervised by a responsible person to ensure that they can use the appliance safely.

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

Do not climb on the outdoor unit or put objects on it.●

Please switch off the unit and turn off the circuit breaker during cleaning, the●

high-speed fan inside the unit may cause danger.

Turn off the circuit breaker if the unit is not to be operated for a long period.

!

The product shall be operated under the manufacturer speciﬁ cation and ●

not for any other intended use.

Do not put water container (like vase) on the indoor unit to avoid water ●

dripping into the unit. Dripping water will damage the insulator inside the unit

and causes short-circuit.

Do not place plants directly under the air ﬂ ow as it is bad for the plants.●

AUTOMATIC OPERATION

The device will automatically determine the mode of operation, HEAT, COOL or DEHUMIDIFY depending on

the current room temperature. The selected mode of operation will change when the room temperature varies.

However the mode of operation will not change when indoor unit connected to multi type outdoor unit.

VARIOUS FUNCTIONS

■ Auto Restart Control

If there is a power failure, operation will be automatically restarted when the power is resumed with previous●

operation mode and airﬂ ow direction.

(As the operation is not stopped by remote controller.)

If you intend not to continue the operation when the power is resumed, switch off the power supply.●

When you switch on the circuit breaker, the operation will be automatically restarted with previous operation

mode and airﬂ ow direction.

Note: 1. If you do not require Auto Restart Control, please consult your sales agent or OFF by remote

control.

2. Auto Restart Control is not available when Timer or Sleep Timer mode is set.

As the settings are stored in memory in the remote controller, you ■

only have to press the (START/STOP) button next time.

Press the FUNCTION selector so that the display indicates the

(AUTO) mode of operation.

When AUTO has been selected, the device will automatically

●

determine the mode of operation, HEAT, COOL or

DEHUMIDIFY depending on the current room temperature.

However the mode of operation will not change when indoor

unit connected to multi type outdoor unit.

If the mode automatically selected by the unit is not●

satisfactory, manually change the mode setting (heat,

dehumidify, cool or fan).

Press the (START/STOP) button.

Operation starts with a beep.

Press the button again to stop operation.

You can raise or lower the temperature setting as necessary by

maximum of 3°C.

Press the temperature button and the

temperature setting will change by 1°C each

time.
