Troubleshooting
The following symptoms do not indicate malfunction.
Symptom Cause
POWER indicator blinks before the unit
is switched on.
• This is a preliminary step in preparation for the
operation when the ON timer has been set.
• When ON Timer is set, the unit may start earlier
(up to 30 minutes) before the actual set time in
order to achieve the desired temperature on time.
TIMER indicator is always on. • The timer setting repeats daily once set.
Operation is delayed a few minutes after
restarting.
• The delay is a protection to the unit’s
compressor.
Indoor fan stops occasionally during
heating operation.
• To avoid unintended cooling effect.
Indoor fan stops occasionally during
automatic fan speed setting.
• This helps to remove the surrounding odour.
Air fl ow continues even after operation
has stopped.
• Extraction of 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 of temperature caused the expansion/
contraction of the unit.
Water fl owing sound during operation. • Refrigerant fl ow inside the unit.
Mist emerges from indoor unit. • Condensation effect due to cooling process.
Outdoor unit emits water/steam. • Condensation or evaporation occurs on pipes.
Discoloration of some plastic parts. • Discoloration is subject to material types used in
plastic parts, accelerated when exposed to heat,
sun light, UV light or environmental factor.
Dust may have collected around the front
panel, grilles and wall surrounding the
unit after extended use.
• The dust accumulation is due to air purification
effect of negative ions from nanoe-G. Remove
the dust regularly with a clean dampened cloth.
