[. . . ] When fitting the unit to wall surface, roof or rooftop, fix a supporter surely with nails or wires in consideration of earthquake and strong wind. If vibration may affect the house, fix the unit by attaching a vibration-proof mat. Indoor Unit Selection of Installation Place 256 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. [. . . ] Insert the drain hose into the dent of heat insulation materials of indoor unit. 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 Piping Pipe supporting plate Lid for right piping Lid for under piping pipe Fix with adhesive tape Lid for left piping Drain hose Indoor/outdoor electric cable 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. 4 Indoor unit 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. 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. If the supply cord is damaged, it must be replaced by the manufacturer or its service agent or a similar qualified person. If the fuse on PC board is broken please change it with the type of T. The breaker should be all-pole switch and the distance between its two contacts should be not less than 3mm. 4 5G1. 0mm2 4 Indoor unit HSU-07RE03/R2 HSU-09RE03/R2 HSU-12RE03/R2 Outdoor unit Indoor unit Power cable:¡Ý3G1. 0mm2 Power cable:¡Ý3G1. 5mm2 5 { ¡Ý POWER PLUG LN G N L 4 +2x0. 75mm2 ¡Ý3G1. 5mm 2 4 HSU-18RE03/R2 HSU-22RE03/R2 Outdoor unit Outdoor unit 1. Installation of Outdoor Unit Install according to Drawing for the installation of indoor and outdoor units 2. 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 max vertical distance between the indoor unit and the outdoor unit is 5 m. 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. [. . . ] Turn the valve rod anticlockwise until hitting lightly. If it does not stop gas leakage, discharge whole refrigerants from the service port. After flaring work again and vacuumize, fill up prescribed refrigerant from the gas cylinder HSU-18RE03/R2 HSU-22RE03/R2 2-way valve 3-way valve 6. 35mm(1/4") 2-way valve 9. 52mm(3/8") 3-way valve HSU-07RE03/R2 HSU-09RE03/R2 HSU-12RE03/R2 Gas Side Liquid Side To prevent the gas leakage, turn the service port's cap, the valve rod's cap for 2-way valve and 3-way's a little more than the point where the torque increases suddenly. 2-way valve 3-way valve Valve rod cap After attaching the each caps, check the gas leakage around the caps. CAUTION: 1. If the refrigerant of the air conditioner leaks, it is necessary to discharge all the refrigerant. [. . . ]
