Operating Recommendations
When you use your air conditioner, it is recommended that you read the following:
Topic Recommendation
Common
Airconditioner should be used only in the single closed room.
Effective airconditioner operation can be guarantee if all windows and doors in the room are
closed.
Heating capacity The heat pump inside the air conditioner absorbs heat from outside air and brings itindoors.
If the temperature of the outside air drops, the air conditioner heats less. If the room is not warm
enough, use an additional heating appliance.
Warm air circulation 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.
Frost
When you select the Heat mode, frost may form in the outdoor unit due to low temperature
and high humidity.
If this happens:
 The heating operation is stopped.
 The air conditioner defrosts automatically for about 7 minutes. After about 7 minutes,
the air conditioner starts operating again normally.
High indoor and
outdoor temperatures
If both the indoor and outdoor temperatures are high when you select the Heat mode,
the fan and the compressor of the outdoor unit may stop periodically.
This is normal; wait until the air conditioner turns on again.
Power failure If a power failure occurs when the air conditioner is operating, the air conditioner will turn off.
When the power returns, the air conditioner will start up again automatically.
Protection mechanism 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.
