  • Page 4 For installation, always contact the dealer or an authorized service center. Do not install the product on a defective installation stand. Be sure the installation area does not deteriorate with age. If the base collapses, the air conditioner could fall with it, causing property damage, product failure, and personal injury.
  • Page 5 There is risk of property damage, failure of product, or electric shock. Do not open the inlet grill of the product during operation. There is risk of physical injury, electric shock, or product failure. When the product is soaked, contact an authorized service centre. There is risk of fire or electric shock.
  • Page 6 There is risk of damage or loss of property. There is risk of fire, electric shock, or damage to the plastic parts of the product. A dirty filter reduces the efficiency of the air conditioner and could cause product malfunction or damage.

  • Page 21 Air and moisture in the refrigerant system have undesirable effects as below: Pressure in the system rises. Operating current rises. Cooling or heating efficiency drops. Moisture in the refrigerant circuit may freeze and block capillary tubing. Water may lead to corrosion of parts in the refrigerant system. Therefore, the indoor units and the pipes between indoor and outdoor units must be leak tested and evacuated to remove gas and moisture from the system.
