Operation tips The following events may occur during normal operation. Protection of the air conditioner. Compressor protection This unit comes with a time delay function to help protect the compressor,please allow 3 minutes for the compressor to restart upon turning on the unit. Anti-cold air (Only for models with heating function) The unit is designed not to blow cold air in HEAT mode when the indoor heat exchanger is in one of the following three situations and the set temperature has not been reached. 1. When heating has just starting. 2. Defrosting. 3. Low temperature heating. Defrosting (Only for models with heating function) Frost may be generated on the outdoor unit during heat cycle when outdoor temperature is low and humidity is high resulting in lower heating efficiency of the air conditioner. During this condition, air conditioner will stop heating operation and start defrosting automatically. The time of defrosting may vary from 0 to 8 minutes according to the outdoor temperature and the amount of frost buildup on the outdoor unit. The indoor or outdoor fan will stop running when defrosting (Only for models with heating function). The indoor unit will display "H1" code when defrosting, it's normal. A white mist coming out from the indoor unit A white mist may generate due to a large temperature difference between air inlet and air outlet in COOL mode in an indoor environment that has high relative humidity. A white mist may generate due to moisture generated from defrosting process when the air conditioner restarts in HEAT mode operation after defrosting. Low noise of the air conditioner You may hear a low hissing sound when the compressor is running or has just stopped running. This sound is the sound of the refrigerant flowing or coming to stop. You can also hear a craching sound when the compressor is running or has just 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 returning to its original position when power is first turned on. Operation tips 22
