Cautions Disposal of the old air conditioner Before disposing an old air conditioner that goes out of use, please make sure it's inoperative and safe. Unplug the air conditioner in order to avoid the risk of child entrapment. It must be noticed that air conditioner system contains refrigerants, which require specialized waste disposal. The valuable materials contained in a air conditioner can be recycled.
Cautions All electrical repairs must be carried out by qualified electricians. Inadequate repairs may result in a major source of danger for the user of the air conditoiner. Do not damage any parts of the air conditioner that carry refrigerant by piercing or perforating the air conditioner's tubes with sharp or pointed items, crushing or twisting any tubes, or scraping the coatings off the surfaces. If the refrigerant spurts out and gets into eyes, it may result in serious eye injuries.

Trouble Shooting The followings are not malfuncition When the air conditoner is started, when the compressor starts or stops during operation or when the air conditioner is stopped,it sometimes sounds Bi- Bi- or Godo-Godo. It is the flowing sound of the refrigerant , not a malfunction. Water flowing sound is heard Hua Hua Cracking sound is heard This is caused by heat expansion or contraction of plastics It smells. Air blown out from the indoor unit sometimes smells.
Trouble Shooting Air does not blow or the fan speed cannot be changed during drying. In DRY mode, when room temperature becomes 2 C higher than temperature setting, unit rill run intermittently at LO speed regardless of FAN setting This happens when the frost accumulated on the outdoor unit is removed (during defrosting operation). Water or vapor generated from the outdoor unit during heating. Defrosting operation During heating,indoor fan is still running even unit is stopped.
