[. . . ] 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 gure. Drawing for the installation of indoor and outdoor units The models adopt HFC free refrigerant R410A Attention must be paid to the rising up of drain hose more than 5cm Optional parts for piping A Non-adhesive tape B Adhesive tape more than 10cm G C Saddle (L.

The distance between the indoor unit and the oor should be more than 2m. [. . . ] After the cable connection, never fail to fasten the connected cable with the wiring cover. Indoor side Outdoor side (Section of wall hole) G Piping hole pipe Installation of the Indoor Unit Drawing of pipe [ Rear piping ] Draw pipes and the drain hose, then fasten them with the adhesive tape [ Left Left-rear piping ] In case of left side piping, cut away, with a nipper, the lid for left piping. In case of left-rear piping, bend the pipes according to the piping direction to the mark of hole for left-rear piping which is marked on heat insulation materials. Note When connecting the cable, con rm 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. 37 HSU-18HEK03/R2 Installation Outdoor unit Installation of Outdoor Unit Install according to Drawing for the installation of indoor and outdoor units 3 4 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 rst makes working easier. 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.

If the pipe has to be lengthened, the refrigerant should be charged, according to 20 g/m. 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. 34 CAUTION Outdoor unit Indoor unit Power cable: . 5mm Connecting wiring: 5mm 2 (For: L N )+2x0. 75mm 2 HSU-18HEK03/R2 HSU-18HEA03/R2 HSU-18RH03/R2 HSU-18HRA03/R2 HSU-18HV03/R2 Outdoor unit Outdoor unit 2 Outdoor unit B A A Indoor unit B Indoor unit B Oil trap Indoor unit A Max. Elevation: Amax=10m In case the elevation A is more than 5m, oil trap shoud be installed every 5~7m Max. Length: Bmax=15m In case the pipe length B is more than 7m, the refrigerant should be charged, according to 20 g/m. 1. If the supply cord is damaged, it must be replaced by the manufacturer or its service agent or a similar quali ed 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 xed wiring. The breaker should be all-pole switch and the distance between its two contacts should be not less than 3mm. 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. [. . . ] Are the connecting wirings of indoor and outdoor rmly inserted to the terminal block?Is the connecting wiring of indoor and outdoor rmly xed?Is power source voltage abided by the code?Are cooling and heating (when in heat pump) performed normally?
