[. . . ] 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. 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. S) with screws Connecting electric cable D for indoor and outdoor E Drain hose F Heating insulating material G Piping hole cover Arrangement of piping directions Rear left Left Rear right Right Below more than 10cm F A Floor fixing dimensions of the outdoor unit (Unit:mm) C more than 10cm The marks from A to G in the figure are the parts numbers. The distance between the indoor unit and the floor should be more than 2m. [. . . ] Install piping hole cover and seal it off with putty after installation Wall hole Ø60mm 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. Indoor side Outdoor side Thickness of wall (Section of wall hole) G Piping hole pipe 2 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. 1. 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. Outdoor unit For the units with fresh air function (for Hvd model) To indoor unit Installation of Outdoor Unit Install according to Drawing for the installation of indoor and outdoor units Indoor unit Outdoor unit To outdoor fresh air motor 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. 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.

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 10m, the refrigerant should be charged, according to 20 g/m. 4G1. 5mm2 Connection Indoor unit 2 Power cable 3G1. 5mm HSU-09RUF03/R2(SDB) Outdoor unit HSU-12RUF03/R2(SDB) 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. [. . . ] Are the connecting wirings of indoor and outdoor firmly inserted to the terminal block?Is the connecting wiring of indoor and outdoor firmly fixed?Is power source voltage abided by the code?Are cooling and heating (when in heat pump) performed normally?
