[. . . ] 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. [. . . ] 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. Indoor side Outdoor side Thickness of wall (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, 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. 2 Outdoor unit Installation of Outdoor Unit Install according to Drawing for the installation of indoor and outdoor units 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.

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. Be careful that matters, such as wastes of sands, etc. If it is over 10m, the function of the unit will be affected. 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. CAUTION Outdoor unit Indoor unit B A B Indoor unit A Outdoor unit Outdoor unit B Max. Elevation: Amax=10m In case the elevation A is more than 5m, oil trap shoud be installed every 5~7m Oil trap Indoor unit A Max. Length: Bmax=15m In case the pipe length B is more than 10m, the refrigerant should be charged, according to 20 g/m. 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. [. . . ] Turn the valve rod anticlockwise until hitting lightly. 7. 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. After attaching the each caps, check the gas Step 1. Is power source voltage abided by the code?Are cooling and heating (when in heat pump) performed normally? [. . . ]
