[. . . ] 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. [. . . ] Flare nut Forced fastening without careful centering Half union may damage the threads and cause a leakage of gas. Pipe Diameter ( ) Fastening torque 18N. m 40N. m 55N. m Liquid side 6. 35mm(1/4") Spanner Torque wrench Gas side 9. 52mm(3/8") Gas side 12. 7mm(1/2") 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. Outdoor unit Outdoor unit A Oil trap Max. Length: A=20m(for: 09k 12k) A=25m(for:18k 22k) Indoor unit Indoor unit Max. Elevation: 10m (for: 09k 12k) 15m(for:18k 22k) CAUTION In case more than 5m Oil trap shoud be installed every 5~7m no more gas if the length of connecting pipe is less than10m 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 Liquid Side 6. 35mm(1/4") Gas Side 9. 52mm(3/8") 12. 7mm(1/2") 3-way valve Gaugemanifold(for R410A) Anti countercurrent joint 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. Then connect the projection of charge hose (center) for gaugemanifold into vacuum pump. Tube(for R410A) Vacuum pump(for R410A) Open the handle at low in gaugemanifold, operate vacuum pump. If the scale-moves of gause (low) reach vacuum condition in a moment, check again. Open Vacuumize for over 15min. And check the level gauge which should read -0. 1 MPa (-76 cm Hg) at low pressure side. After the completion of vacuumizing, close the handle 'Lo' in gaugemanifold and stop the operation of the vacuum pump. Check the condition of the scale and hold it for 1-2min. If the scale-moves back in spite of tightening, make flaring work again, the return to the beginning of . Close Open the valve rod for the 2-way valve to an angle of anticlockwise 90 degrees. After 6 seconds, close the 2-way valve and make the inspection of gas leakage. 2-way valve 90 Open o 6. 35mm(1/4") 3-way valve Service port 90ofor 6 sec. Liquid Side 9. 52mm(3/8") 12. 7mm(1/2") 3-way valve Gas Side 2-way valve In case of gas leakage, tighten No gas leakage?Detach the charge hose from the service port, open 2-way valve and 3-way. Turn the valve rod anticlockwise until hitting lightly. If it does not stop gas leakage, discharge whole refrigerants from the service port.
