Installation Installation Important Notices 1. The unit installation work must be done by qualified personnel according to the local rules and this manual 2. Before installating, please contact with local authorized maintenance center, if unit is not installed by the authorized maintenance center, the malfunction may not solved due to discommodious contacts 3. - Page 35 Installation Safety Requirements For Electric Appliances 1. The power supply should be used the rated voltage and AC exclusive circuit, the power cable diameter should be satisfied. 2. Don't drag the power cable emphatically. It should be reliably earthed, and it should be connected to the special earth device, the installation work should be operated by the professional.
- Page 36 Installation Install the rear panel 1.Always mount the rear panel horizontally. Due to the water tray of indoor unit has been adopted the both-way drainage design, the outlet of water tray should be adjusted slightly down when installing, that is taking the outlet of the water tray as the center of a circle, the included angle between the evaporator and level should be 0 or more, that is good for condensing water drainage.
- Page 37 Installation NOTE: When connecting the electric wire if the wire length is not enough, please contact with the authorized service shop to buy a exclusive electric wire that is long enough and the joint on the wire are not allowed. The electric wiring must be correctly connected, wrong connection may cause spare parts malfunction.
