If the outdoor temperature is as low as 0°C, the heating capacity drops up to 70~80% depending on the operating condition.
If you use the air conditioner in temperatures over 32°C (indoor temperature), the cooling capacity may drop.
Operating Recommendations
Here are a few recommendations that you should follow when using your air conditioner.
TopicRecommendation
Heating performances | 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. |
|
|
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 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. |
|
|
High indoor and | If both indoor and outdoor temperatures are high and the air conditioner is running at HEAT |
outdoor temperatures | mode, the outdoor unit’s fan and compressor may stop at times. This is normal;simply wait until |
| the air conditioner switches on again. |
|
|
Power failure | 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. |
|
|
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. |
|
|
Cooling operation | 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. |
|
|
Silence Mode | When you operate Silence Mode in cooling and heating, fan speed will decrease to make noise |
| quieter. |
| As a result, the performance of the unit may be reduced. |
