If it is over 7m, the function of the unit will be affected. If the pipe has to be lengthened, the refrigerant should be charged, according to 50 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 B A Indoor unit B Indoor unit A Outdoor unit Outdoor unit B Oil trap Indoor unit A Indoor unit Connecting wiring: AWG18X6, Power Cable: AWG12X3. Outdoor unit Connection Max. Elevation: Amax=15m In case the elevation A is more than 5m, oil trap shoud be installed every 5~7m Max. Length: Bmax=25m = In case the pipe length B is more than 7m, the refrigerant should be charged, according to 20 g/m. (for 18k) In case the pipe length B is more than 7m, the refrigerant should be charged, according to 50 g/m. (for 24k) SN-24000-H 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. Take off the panel(top), by removing the 5 screws. Temporarily mount the conduit tubes on the conduit plate. Connect both the power supply and unit wire harness to the corresponding terminals on the terminal board. [. . . ] 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? [. . . ]
