OPERATION TIPSThe following events may occur during normal operation.1. Protection of the air conditioner.Compressor protectionThe compressor can't restart for 3 minutes after it stops.Anti-cold air (Cooling and heating models only)The unit is designed not to blow cold air on HEAT mode, when the indoor heat exchanger is inone of the following three situations and the set temperature has not been reached.A) When heating has just starting.B) Defrosting.C) Low temperature heating.The indoor or outdoor fan stop running when defrosting (Cooling and heating models only).Defrosting (Cooling and heating models only)Frost may be generated on the outdoor unit during heat cycle when outdoor temperature is lowand 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 to defrost may vary from 4 to 10 minutes according to the outdoor temperature andthe amount of frost buildup on the outdoor unit.2. A white mist coming out from the indoor unitA white mist may generate due to a large temperature difference between air inlet and air outleton COOL mode in an indoor environment that has a high relative humidity.A white mist may generate due to moisture generated from defrosting process when the airconditioner restarts in HEAT mode operation after defrosting.3. Low noise of the air conditionerYou 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 a stop.You can also hear a low "squeak" sound when the compressor is running or has just stoppedrunning. This is caused by heat expansion and cold contraction of the plastic parts in the unitwhen the temperature is changing.A noise may be heard due to louver restoring to its original position when power is first turned on.4. Dust is blown out from the indoor unit.This is a normal condition when the air conditioner has not been used for a long time or during firstuse of the unit.5. A peculiar smell comes out from the indoor unit.This is caused by the indoor unit giving off smells permeated from building material, from furniture,or smoke.96. The air conditioner turns to FAN only mode from COOL or HEAT (For cooling andheating models only) mode.When indoor temperature reaches the temperature setting on air conditioner, the compressor willstop automatically, and the air conditioner turns to FAN only mode. The compressor will start againwhen the indoor temperature rises on COOL mode or falls on HEAT mode (For cooling and heatingmodels only) to the set point. |
