• 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
15 minutes ( Cooling model) / 30 minutes (
*1
model) before the actual set time to achieve the desired
temperature on time.
• When Timer has been set, the Timer setting repeats
daily.
• The delay is a protection to the unit's compressor.
• This is to help remove the surrounding odour.
• Extraction of remaining heat from the indoor unit
(maximum 30 seconds).
• This may be due to damp smell emitted by the wall,
carpet, furniture or clothing.
• Changes in temperature caused the unit to expand and
contract.
• Refrigerant fl ow inside the unit.
• During cooling operation, the discharged cold air may
condense to water vapour.
• During cooling operation, condensation occurs on
cold pipes and the condensed water may drip from the
outdoor unit.
• The compressor and fan rotate at higher speed to
boost cooling performance during initial operation.
• 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.
• The dust accumulation is due to the air purifi cation
effect of negative ions from nanoe™-G. Remove the
dust regularly with a clean dampened cloth.
• It is normal when the nanoe™X generator is working.
If you are concerned about the sound, cancel the
nanoe™ TECHNOLOGY operation.
• The unit's wireless LAN connection with the router has
been activated.
