Page 3: Precaution
„ 1. Precaution „ 1.1 Safety Precaution. z To prevent injury to the user or other people and property damage, the following instructions must be followed. z Incorrect operation due to ignoring instruction will cause harm or damage. Before service unit, be sure to read this service manual at first. „... - Page 4 z Do not install the product on a defective installation stand. It may cause injury, accident, or damage to the product. z 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 z Do not open the inlet grill of the product during operation. (Do not touch the electrostatic filter, if the unit is so equipped.) There is risk of physical injury, electric shock, or product failure. z When the product is soaked (flooded or submerged), contact an Authorized service center. There is risk of fire or electric shock.
- Page 6 Operational z Do not expose the skin directly to cool air for long periods of time. (Do not sit in the draft). This could harm to your health. z Do not use the product for special purposes, such as preserving foods, works of art, etc. It is a consumer air conditioner, not a precision refrigerant system There is risk of damage or loss of property.
- Page 7 Warning z Do not use means to accelerate the defrosting process or to clean, other than those recommended by the manufacturer. z The appliance shall be stored in a room without continuously operating ignition sources (for example: open flames, an operating gas appliance or an operating electric heater). z Do not pierce or burn.
