Error Codes:

Fault Diagnosis

■ To perform error code diagnosis
1. Press and hold

button for 5 seconds.

•

blinks.

2. Press or to check on the error code.
• Press on the button repeatedly until a long "beep" acknowledgement heard from the indoor unit.

■ To exit from error code diagnosis
3. Press and hold or button for 5 seconds.
• The code display will cancel itself if the button is not pressed for 1 minute.

n Note

• A short "beep" and two consecutive "beep" acknowledgement from the indoor unit indicates a non-correspondence error code.
• User shall not attempt to repair or modify the air conditioner as any incorrect work may result in electric shock or fire.
• Consult the service personnel in case the air conditioner is found to be faulty.

TROUBLESHOOTING

For any enquiries on spare parts please contact your authorized dealer. If any malfunction of the air conditioner unit is noted, immediately switch off the power supply to the unit. Check the following fault conditions and causes for some simple troubleshooting tips.

Fault

Causes / Action

1. The compressor does not operate 3 minutes after the air conditioner unit is started.

– Protection against frequent starting. Wait for 3 to 4 minutes for the compressor to start operating.

2. The air conditioner unit does not operate.

– Power failure, or the fuse needs to be replaced.
– The power plug is disconnected.
– It is possible that your delay timer has been set incorrectly.
– If the fault persists after all these verifications, please contact the air conditioner unit installer.

3. The air flow is too low.

– The air filter is dirty.
– The doors or windows are open.
– The air suction and discharge are clogged.
– The regulated temperature is not high enough.

4. Discharge air flow has bad odor.

– Odors may be caused by cigarettes, smoke particles, perfume etc. which might have adhered onto the coil.

5. Condensation on the front air grille of the indoor unit.

– This is caused by air humidity after an extended long period of operation.
– The set temperature is too low, increase the temperature setting and operate the unit at high fan speed.

6. Water flowing out from the air conditioner unit.

– Switch off unit and call dealer.

7. Insufficient heating during heating operation (Multi Split Inverter System)

– If more than one room are being heated simultaneously during winter, it is possible that more time is needed to warm up the rooms.
– Switch on heating operation in one room and continue to operate up to a certain extent before heating up the other room.

8. Insufficient cooling during cooling operation (Multi Split Inverter System)

– If more than one room are being cooled simultaneously, it is possible that more time is needed to cool down the rooms.
– Switch on cooling operation in one room and continue to operate up to a certain extent before cooling down the other room.

If the fault persists, please call your local dealer / serviceman.
