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
(30 minutes) before the actual set time to achieve the
desired temperature on time.
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.
Indoor fan stops occasionally during automatic
fan speed setting. • This is to help 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 in temperature caused the unit to expand and
contract.
Water fl owing sound during operation. • Refrigerant fl ow 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.
Louder noise at outdoor unit during early
operation of i AUTO-X. • The compressor and fan rotate at higher speed to
boost cooling performance during initial operation.
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.
After extended use, dust may cover the front
panel, grilles and the wall surrounding the
unit. • The dust accumulation is due to the air puri fi cation
effect of negative ions from nanoe™-G. Remove the
dust regularly with a clean dampened cloth.
Soft buzzing sound from indoor unit during
nanoe™ TECHNOLOGY operation. • It is normal when the nanoe™X generator is working.
If you are concerned about the sound, cancel the
nanoe™ TECHNOLOGY operation.
Wireless LAN indicator is ON when the unit
is OFF. • The unit’s wireless LAN connection with the router has
been activated.
