[. . . ] 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. [. . . ] 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. 4 Indoor unit 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. 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.

Installation of Outdoor Unit Install according to Drawing for the installation of indoor and outdoor units 2. Connection of pipes Apply refrigerant oil on half union and flare nut. 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. Half union Flare nut Forced fastening without careful centering may damage the threads and cause a leakage of gas. Pipe Diameter Liquid side 6. 35mm(1/4") Liquid side 9. 52mm(3/8") Gas side 12. 7mm(1/2") Fastening torque 18N. m 42 N. m 55N. m 60 N. m Spanner Torque wrench Gas side 15. 88mm(5/8") Be careful that matters, such as wastes of sands, etc. If it is over 5m, 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. 3. Connection Use the same method on indoor unit. [. . . ] 2-way valve 2-way valve 3-way valve 6 Detach the charge hose from the service port, open 2-way valve and 3-way valve . 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. 8 After attaching the each caps, check the gas leakage around the caps.
