[. . . ] 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. The power source is the same as the corresponding name plate. [. . . ] 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 H05/07RN-F or 245IEC57(YZW). 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.

Installation of Outdoor Unit Install according to Drawing for the installation of indoor and outdoor units Figure 3 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. Connecting the pipe of gas side first makes working easier. Half union Flare nut Forced fastening without careful centering may damage the threads and cause a leakage of gas.

[. . . ] Piping length Additional amount 5m No need 7m 32g HSU-22CVY03 10m 80g Note: When extending piping, air inside piping shall be removed by using external refrigerant gas, charge according to the following list. Brand new outdoor unit is charged 50g(18k) or 80g(24k) more refrigerant than regulated weight. Only for first installation, this extra 50g(18k) or 80g(24k) can be used to purge air in pipes. During this procedure, 50g(18k) or 80g(24k) refrigerant will be discharged in piping. [. . . ]
