Operating Recommendations
Here are a few recommendations that you should follow when operating your air conditioner. Topic Heating performances Recommendation 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. When outside temperature is low but humidity is high, frost may form on the outdoor unit at HEAT mode. If this happens: N The heating operation stops. N The defrost mode will be triggered automatically for about 10 minutes. N The steam produced on the outdoor unit in the defrost mode is safe. No intervention is required ; after about 10 minutes, the air conditioner operates again normally. High indoor and outdoor temperatures If both indoor and outdoor temperatures are high and the air conditioner is running at HEAT mode, the outdoor units 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.
