Operating Recommendations
The heat pump function of the air conditioner
absorbs heat from outside air and brings it
indoors. As the temperature of the outside air
drops, the heating performance of air
conditioner will decrease. If you find that the
room is not warm enough, using an additional
heating appliance is recommended.
The air conditioner circulates warm air to heat
your room. It will take some time to warm the
air in your room entirely after the air
conditioner turns on. Therefore, turn the air
conditioner on in advance.
When outdoor temperature is low but humidity
is high, frost may form on the outdoor unit at
Heat mode.
◆The heating operation stops.
◆The defrost mode will be triggered automatically
for 3 to 14 minutes.
No intervention is required ; after about 7 minutes,
the air conditioner operates again normally.
If both indoor and outdoor temperatures are
high and the air conditioner is running at HEAT
mode, the outdoor unit’s fan and compressor
may stop at times. This is normal; simply wait
until the air conditioner switches on again.
If a power failure occurs while the air
conditioner is operating, the unit will be
switched off. When the power returns, the air
conditioner starts up again automatically.
When the air conditioner is started
immediately after being plugged in or stopped,
the normal operation starts up after 3 minutes
for the reason of protection.
The indoor unit may not get the selected fan
speed such as Medium and Low under cooling
operation at very low outdoor temperatures
for the protection of the indoor unit from ice
or frost.
During Low fan speed operation,
cooling performance will be reduced.
If the room does not be cooled down when
using Low fan speed operation,
please adjust the indoor unit’s fan speed.
