Troubleshooting

The following symptoms do not indicate malfunction.

Symptom Cause

POWER indicator blinks before the unit is

switched on.

• This is the preliminary step to prepare for the TIMER

operation after it has been set.

When Timer is set ON, the unit may start earlier (up to

35 minutes) before the actual set time to achieve the

desired temperature on time.

POWER indicator blinks during HEAT mode

with no warm air supply (and ﬂap is closed).

• The unit is in defrost mode (and AIR SWING has been

set to AUTO).

POWER indicator blinks, then stops blinking

during COOL/DRY mode.

• The system has been locked to operate in HEAT mode

only.

TIMER indicator is always ON. • When Timer has been set, the Timer setting repeats

daily.

Operation is delayed a few minutes after

restarting.

• The delay is a protection to the unit’s compressor.

Cooling/heating capacity is reduced during

lowest fan speed setting.

• The lowest fan speed is to have a low noise operation,

so cooling/heating capacity may be reduced depending

on the condition. Increase the fan speed to increase the

capacity.

Indoor fan stops occasionally during heating

operation.

• To avoid unintended cooling effect.

Indoor fan stops occasionally during automatic

fan speed setting.

• This is to help remove the surrounding odour.

Airﬂow continues even after operation has

stopped.

• To extract the remaining heat from the indoor unit

(maximum 30 seconds).

The room has a peculiar odour. • This may be due to damp smell emitted by the wall,

carpet, furniture or clothing.

Cracking sound during operation. • Changes in temperature caused the unit to expand and

contract.

Water ﬂowing sound during operation. • Refrigerant ﬂow inside the unit.

Mist emerges from indoor unit. • During cooling operation, the discharged cold air may

condense to water vapour.

Outdoor unit emits water or steam. • During cooling operation, condensation occurs on

cold pipes and the condensed water may drip from the

outdoor unit.

• During heating operation, frost formed on the outdoor

unit during deice cycle melts and is discharged as

water or steam.

Discoloration of some plastic parts. • Discoloration is subjected to the types of materials

used in plastic parts. It is accelerated when exposed to

heat, sun light, UV light or environmental factors.

Soft buzzing sound from indoor unit during

nanoe™X operation.

• It is normal when the nanoe™X generator is working.

If you are concerned about the sound, cancel the

nanoe™X operation.

Wireless LAN indicator is ON when the unit

is OFF.

• The unit’s wireless LAN connection with the router has

been activated.
