A saline place such as a seashore vicinity A place with sulphur gas. A place with oil gas, such as kitchen. A place with high-humidity air. An unbearable place. A place where high-frequency waves are generated. The appliance shall not be installed in the laundry.
No. Model Unit mm Steel roof beam structure Install the supporting angle steel. Hanging screw bolt Hanging bolts Please accord to the follow figure’s requirements to design the length of the suspender bolt. Supporting angle steel Fig.5-5 Hoisting the indoor unit take 18-36 as an example, operation method of 45-71are the same.
Install the panel component, and wiring (take 18-36 as an example, operation method of 45-71 are the same.) Two buckles on the panel component are used for assisting the panel installation, the installing method of the buckle as Fig.5.10 display. Panel component wiring: open the electric control panel, connect the wiring terminal of the control display box and the motor connecting terminal of the air leading bar as the figure display to the main control panel.
. DRAINPIPE INSTALLATION Install the screw Before installation please check the connecting cable etween panel and air conditioner whether has clamped, if clamped, the panel will be unfairness after fastening the screws and When connecting the pipe, please use the sealing material and pipe glove. damage the wires. CAUTION The drain pipe of indoor unit must be heat insulated, or it will condense dew, as well as the connections of the indoor unit. Make sure the connections is no leakage.
Please according to the tube hardness to choose proper support density, do not appear obvious dropping and deformation situation. Dropping part will save the water and lead to poor drainage and abnormal noise. 7. INSTALL THE CONNECTING PIPE The connective length of indoor and outdoor piping and those height difference requirements. Connect to different outdoor units with different connective length and height difference requirements. Please refer to Indoor Unit Installation Manual for detail.

Bind the connecting pipe and the cables together tightly with binding tapes.
. WIRING CHART Air Purging Attaching wiring Use a vacuum pump, to vacuum from the gas side refrigerant adding mouth of the outdoor unit. The air conditioner should use separate power supply with rated voltage. Don’t use the refrigerant of the outdoor unit to do the vacuum. (A certain volume of refrigerant had been added into the outdoor unit in factory.) The external power supply to the air conditioner should have ground wiring, which is linked to the ground wiring of the indoor and outdoor unit.
