[. . . ] In the case of fixing the remote controller on a wall, place where the indoor unit can receive signals when the fluorescent lamps in the room are lightened. Place, which is less affected by rain or direct sunlight and is sufficiently ventilated. Place, possible to bear the unit, where vibration and noise are not increased. Place, where discharged wind and noise do not cause a nuisance to the neighbors. Place, where a distance marked is available as illustrated in the above figure. Power Source Before inserting power plug into receptacle, check the voltage without fail. [. . . ] 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 Piping Drain hose 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. When bending, be careful not to crash pipes. 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. Move the body from side to side to verify its secure fixing. 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. If the supply cord is damaged, it must be replaced by the manufacturer or its service agent or a similar qualified person. The type of connecting wire is H05RN-F or H07RN-F. If the fuse on PC board is broken please change it with the type of T. The wiring method should be in line with the local wiring standard. After installation, the power plug should be easily reached. A breaker should be incorporated into fixed wiring. The breaker should be all-pole switch and the distance between its two contacts should be not less than 3mm YEL/GRN 4 WHT BLK 1(L) 2(N) 3G2. 0mm2 BLK WHT Indoor unit Power cable: AWG12 YEL/GRN Outdoor unit SFST18TR3 YEL/GRN BR WHT BLK 1 BR YEL/GRN 2 4 BLK WHT { BR BLU YEL/GRN L POWER PLUG N Indoor unit Outdoor unit SFST24TR3 5 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 Connecting the pipe of gas side first makes working easier. 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.

Connection Use the same method on indoor unit. [. . . ] Brand new outdoor unit is charged 50g or 80g(only for 24k unit) more refrigerant than regulated weight. Only for first installation, this extra 50g or 80g(only for 24k unit) can be used to purge air in pipes. During this procedure, 50g or 80g(only for 24k unit) refrigerant will be discharged in piping. (This must be strictly controlled within 90 and 10 sec. ) o 7 1. Power Source Installation The power source must be exclusively used for air conditioner. [. . . ]
