OPERATION TIPS

The following events may occur during normal operation.
P
Compressor protection
• The compressor cannot restart for 3 minutes after it stops.
Anti cold air (Cooling and heating models only)
• The unit is designed not to blow cold air on EAT mode, when the indoor heat exchanger is in one of the following
three situations and the set temperature has not been reached.
A) When heating has ust starting.
) efrosting.
C) Low temperature heating.
• The indoor or outdoor fan stop running when defrosting (Cooling and heating models only).
efrosting (Cooling and heating models only)
• Frost may be generated on the outdoor unit during heat cycle when outdoor temperature is low and humidity is
high resulting in lower heating ef ciency of the air conditioner.
• uring this condition air conditioner will stop heating operation and start defrosting automatically.
• The time to defrost may vary from 4 to 10 minutes according to the outdoor temperature and the amount of frost
buildup on the outdoor unit.
A
• A white mist may generate due to a large temperature di erence between air inlet and air outlet on COOL mode
in an indoor environment that has a high relative humidity.
• A white mist may generate due to moisture generated from defrosting process when the air conditioner restarts in
EAT mode operation after defrosting.
L
• ou may hear a low hissing sound when the compressor is running or has ust stopped running.
This sound is the sound of the refrigerant owing or coming to a stop.
• ou can also hear a low s ueak sound when the compressor is running or has ust stopped running. This is
caused by heat expansion and cold contraction of the plastic parts in the unit when the temperature is changing.
• A noise may be heard due to louver restoring to its original position when power is rst turned on.
D
This is a normal condition when the air conditioner has not been used for a long time or during
A
This is caused by the indoor unit giving o smells permeated from building material, from furniture, or smoke.
T
When indoor temperature reaches the temperature setting on air conditioner, the compressor will stop automatically,
and the air conditioner turns to FAN only mode. The compressor will start again when the indoor temperature rises
on COOL mode or falls on EAT mode (For cooling and heating models only) to the set point.
ripping water may generate on the surface of the indoor unit when cooling in a high relatively humidity (relative
humidity higher than 80 ). Ad ust the horizontal louver to the maximum air outlet position and select I
H
The air conditioner draws in heat from the outdoor unit and releases it via the indoor unit during heating operation.
When the outdoor temperature falls, heat drawn in by the air conditioner decreases accordingly. At the same time,
loading of the air conditioner increases due to larger di erence between indoor and outdoor temperature. If a comfortable
temperature cannot be achieved by the air conditioner, we suggest you use a supplementary heating device.
A
Power failure during operation will stop the unit completely.
For the unit without Auto restart feature, when the power restores, the OPERATION indicator on the indoor unit
starts ashing. To restart the operation, push the ON/OFF button on the remote controller. For the unit with Auto
restart feature, when the power restores, the unit restarts automatically with all the previous settings preserved by
the memory function.
L
isconnect the unit with power and then re connect the unit with power again. Push the ON/OFF button on the
remote controller to restart operation.
