Cleaning and Maintenance

IMPORTANT: Clean the front grille and air lters at least once in every two weeks.

Before cleaning, be sure to stop operating the air conditioner and turn o the

breaker.

NOTE: The illustrations shown below are only for descriptive purposes. Please always

refer the actual product purchased while using these instructions.

Clean the Front Grille and Air Filters

1. Open the front grille by pulling the tabs on both sides and lift it up until it stops

with a click. Pull out the air lters.

2. Remove all dust on the front grille and air lters with a vacuum cleaner or brush.

(If the dust does not come o easily, wash the air lters with gentle detergent

dissolved in clean, warm water below 45

˚C

3. Dry them thoroughly in the shade.

4. Once dry, insert the front grille and air lters back into their original position and

close the front grille.

5. Wipe the surface of the unit with moist cloth and then wipe it again with dry

cloth.

CAUTION: Do not use benzene, solvent, alkaline or other chemical products during

cleaning.

If you will not be using the air conditioner for a long, idle period

1. Set the fan going for a few hours to dry out the inside thoroughly. (Choose the

Cool mode or Heat mode and select the highest set temperature, then the fan

rotates.)

2. Switch the air conditioner o and unplug it from the wall socket. Clean the lters

and outer surface.

3. Take out the batteries from the remote controller.

Cleaning and Maintenance continued

If you have not used the air conditioner for a long time

1. Clean lters and replace them to the original position. Clean the indoor and

outdoor units with a clean, soft cloth.

2. Insert the power plug and make sure the earth wire not be loose.

3. Put the batteries into the remote controller.

IMPORTANT:

• Air inlets and outlets should not be covered/blocked. Double check they are not

before using the air conditioner.

• For cleaning, do not use gasoline, benzene, thinners of any kind, grinding

powder, detergent, alkaline cleaning agents, insecticide etc. as they can damage

the units.

Troubleshooting

The following fault cases are served as a guide to assess a problem and take correct

action on it.

Problem Possible Solutions

Air conditioner does not operate - Is it a power failure?

- Has the power plug been unplugged?

- Has the circuit breaker or fuse shut o?

- Are there any obstacles or disturbance

supply oscillators in the room to disturb

the signal from remote controller?

Remote controller is not available

and does not display

- Check whether the batteries in remote

controller are usable.

- Check whether the batteries are

positioned correctly

Operation does not start when

I/O button is pressed after

operation was stopped

- This is a way to protect the air conditioner.

Please wait 3 minutes and try again

After operation terminates,

the vane appears not to close

completely

- Stepping motor could not nd the Reset

point. Please restart the air conditioner

and stop again

Cooling and heating eect is not

good.

- Is the temperature setting appropriate?

- Are the air lters clean?

- Are there any obstacles blocking the inlets

and outlets of the indoor and outdoor

units?

- Is Sleep mode used during the daytime?

- Is the indoor fan speed set low?

- Are doors and windows closed?

Air will not immediately blow out

at the start of Heat mode

- Please wait as the air conditioner is

warming up

If the power supply is suddenly

cut o, when the power is normal

again, the air conditioner will

automatically resume the in same

mode of operation as before the

power failure

- This is called auto-restart function.

(This function is only accessible for certain

types of air conditioners with the function

of auto-restart)

Problem Possible Solution

Indoor unit fan stops

during heating

The air conditioner is deicing and it takes

10 minutes at most. (It freezes when the

outdoor temperature is low and humidity

is high.) It automatically resumes operation

about 10 minutes later

Cracking sounds can be heard -

The friction sounds are caused by expansion

and contraction of front grille resulting

from temperature changes

You can hear the sound of

running water

- It is the sound of owing refrigerant inside

the air conditioner.

- Sound of accumulated owing water on

the Heat-exchanger.

- Sound of frost melting on the heat

exchanger

Indoor unit makes “bush” and/or

“click” sound

- Click sound is made by the switching of

the fan or compressor. The“bush” sound is

made by the switch of refrigerant owing

inside the air conditioner

When the unit is set to directional

swinging at low angle on Cool

mode: the deector will/may

auto swing to its maximum angle

for 3 minutes and then resume to

swing at the low angle

- This function prevents the production of

condensed water. It is a normal operation

for the air conditioner

Indoor unit gives odour - Air conditioner may have absorbed odours

from wall, carpet, furniture and in turn

blows it out

- Follow the Cleaning and Maintenance

procedures

Outdoor unit leaks water -

During cooling, connecting pipe or pipe

connector will cause the moisture content

condensation due to the low temperature.

- During heating or defrosting, melting

water and water vapor will run out.

- During heating, water on heat exchanger

will drop
