[. . . ] 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. [. . . ] 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 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. Forced fastening without careful The connection pipe is specialized for R410A. Half union Flare nut 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. Outdoor unit Indoor unit Outdoor unit B A B Indoor unit A B Oil trap Indoor unit A Outdoor unit CAUTION Max. Elevation: A1 =10m(for: 09k 12k), A2=15m(for:18k ) In case the elevation A is more than 5m, oil trap shoud be installed every 5~7m In case A is more than 5m Max. Length:B1=15m(for: 09k 12k), B2=25m(for:18k ) In case the pipe length B is more than 10m, the refrigerant should be charged, according to 20 g/m. 3. 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. Fix the cable with a clamp. 4. Attaching Drain-Elbow If the drain-elbow is used, please attach it as figure. (Note: Only for heat pump unit. ) 6 Outdoor unit 5. Purging Method:To use vacuum pump 2-way valve Detach the service port's cap of 3-way valve, the valve rod's cap for 2-way valve and 3-way's, connect the service port into the projection of charge hose (low) for gaugemanifold. [. . . ] CAUTION: 1. If the refrigerant of the air conditioner leaks, it is necessary to discharge all the refrigerant. Vacuumize first, then charge the liquid refrigerant into air conditioner according to the amount marked on the name plate. 2. Please do not let other cooling medium, except specified one (R410A), or air enter into the cooling circulation system. Otherwise, there will be abnormal high pressure in the system to make it crack and lead to personal injuries. [. . . ]
