[. . . ] If vibration may affect the house, fix the unit by attaching a vibration-proof mat. Indoor Unit Selection of Installation Place 319. 5 Outdoor Unit Place, robust not causing vibration, where the body can be supported sufficiently. Place, not affected by heat or steam generated in the vicinity, where inlet and outlet of the unit are not disturbed. Place, possible to drain easily, where piping can be connected with the outdoor unit. Place where the distance of more than lm from televisions, radios, wireless apparatuses and fluorescent lamps can be left. [. . . ] Insert the indoor/outdoor electric cable from backside of indoor unit, and pull it out on the front side, then connect them. Cover the connection part with heat insulation materials closely, and make sure fixing with adhesive tape Heat insulation material Lid for right piping Lid for under piping Lid for left piping Drain hose Piping Pipe supporting plate Indoor/outdoor electric cable Fix with adhesive tape Indoor/outdoor electric cable and drain hose must be bound with refrigerant piping by protecting tape. [Other direction piping] Cut away, with a nipper, the lid for piping according to the piping direction and then bend the pipe according to the position of wall hole. Connect beforehand the indoor/outdoor electric cable, and then pull out the connected to the heat insulation of connecting part specially. Fixing the indoor unit body Hang surely the unit body onto the upper notches of the mounting plate. In order to fix the body onto the mounting plate, hold up the body aslant from the underside and then put it down perpendicularly. 4. Connecting the indoor/outdoor Electric Cable Removing the wiring cover Remove terminal cover at right bottom corner of indoor unit, then take off wiring cover by removing its screws. When connecting the cable after installing the indoor unit 1. Insert from outside the room cable into left side of the wall hole, in which the pipe has already existed. Pull out the cable on the front side, and connect the cable making a loop. 4 Indoor unit When connecting the cable before installing the indoor unit Insert the cable from the back side of the unit, then pull it out on the front side. Loosen the screws and insert the cable ends fully into terminal block, then tighten the screws. Pull the cable slightly to make sure the cables have been properly inserted and tightened. After the cable connection, never fail to fasten the connected cable with the wiring cover. Note: When connecting the cable, confirm the terminal number of indoor and outdoor units carefully. If wiring is not correct, proper operation can not be carried out and will cause defect.

Connection of pipes To bend a pipe, give the roundness as large as possible not to crush the pipe , and the bending radius should be 30 to 40 mm or longer. The connection pipe is specialized for R410A. Half union Flare nut Forced fastening without careful centering may damage the threads and cause a leakage of gas.

But the charge of refrigerant must be conducted by professional air conditioner engineer. Before adding additional refrigerant, perform air purging from the refrigerant pipes and indoor unit using a vacuum pump, then charge additional refrigerant. 3. Connection Use the same method on indoor unit. Loosen the screws on terminal block and insert the plugs fully into terminal block, then tighten the screws. Insert the cable according to terminal number in the same manner as the indoor unit. If wiring is not correct, proper operation can not be carried out and controller may be damaged.
