4.1 Electrical Safety Precautions
12K models power supplied by indoor unit
• The air conditioner must be grounded.
• Insufficient grounding may cause electric shocks. Do not connect the grounding wire to gas pipes, water pipes, lightning
conductors or telephone grounding wire. After mounting, the appliance should be powered up in order to determine grounding
leak check. If you neglect, it may cause electric shocks and damages in the product.
• In order to prevent overloading of the electrical circuit, do not operate any other high-power appliance on the same circuit. Do not
connect with extension cables or multi plugs. If you neglect, it may cause electric shocks or damages in the air conditioner.
• Use a dedicated mains circuit for the AC.
• Do not use a damaged or low value circuit breaker.
• Make sure that the live wire, the neutral wire and the ground wire in the mains socket are properly connected.
• Inadequate or incorrect electrical connections can cause electric shock or fire.
• Do not change the power cord or extend it with improper addition.
• The unit is a type I electrical appliance. Make sure that the unit is properly grounded. The yellow-green wire is the ground wire
that cannot be used for other purposes. Improper grounding can cause electric shock.
• The unit must be reliably earthed and connected to the special earth device by the qualified electrician.
• The ground resistance must comply with local regulations.
• The mains supply must have reliable ground terminal. Do not connect the ground wire to water pipes, gas pipes, contamination
pipes or other possible unsafe places.
• Fuses must comply with the prescribed model and rating printed on the fuse cover or circuit board.
• If the length of the power cord is not enough, please contact your supplier for new power cord. Lengthen the power cord by
yourself is not allowed.
• Do not connect two power cables together to supply power to the air conditioner.
• Do not extend the power cable conductor by cutting.
4.2 Installation Safety Precautions
• After the mounting, electrical switch/fuse should be easily accessible.
• Do not install the unit in areas with strong heat sources, vapours or flammable gasses, contamination with oil particles, high
frequency electromagnetic equipment (e.g. welding equipment or medical devices), high salinity (e.g. close to coastal areas),
sulphuric gas (e.g hot water springs), poor air quality.
• Install the indoor and outdoor unit out of reach of children.
• The wall must be strong enough to support the weight and vibration of the unit.
• Leave at least 1 m distance between the unit and other electrical appliances.
• Wear safety belt if the height of working is above 2m.
• Do not touch the product with wet hands.
• Do not allow water to run into electric parts.
4.3 Transportation Safety Precautions
• During handling and transportation of your air conditioner, watch out the ARROW sign while handling the indoor unit.
• Do not step on and do not put heavy objects on the indoor and outdoor unit boxes.
• Carry the outdoor unit vertically and keep it vertically at the place it is stored.
• Do not carry the outdoor unit only one person.
