2. The wiring method should be in line with the local wiring standard.3. After installation, the power plug should be easily reached.4. A breaker should be incorporated into fixed wiring. The breaker should beall-pole switch.Outdoor unitInstall according to Drawing for the installation of indoor and outdoor unitsƽand the bending radius should be 30 (1 1/6) to 40 mm (1 4/7) or longer.Connecting the pipe of gas side first makes working easier.ƽThe connection pipe is specialized for R410A.ƽInstallation of Outdoor UnitHalf union Flare nutTorque wrenchThe standard pipe length is 7m (27 9/16) . If it is over 7m (27 9/16) , the functionof the unit will be affected. If the pipe has to be lengthened, the refrigerant shouldbe charged, according to 20 g/m (0.018 oz/inch). But the charge of refrigerant mustbe conducted by professional air conditioner servicer. Before adding additionalrefrigerant, perform air purging from the refrigerant pipes and indoor unit usinga vacuum pump,thenSpannerForced fastening without careful centering maydamage the threads and cause a leakage of gas.Pipe Diameter(ǿ) Fastening torqueLiquid side6.35mm(1/4") 18N.m/13.3Ft.lbsLiquid/Gas side9.52mm(3/8") 42 N.m/30.1Ft.lbsGas side 12.7mm(1/2") 55N.m/40.6Ft.lbsGas side 15.88mm(5/8") 60 N.m/44.3Ft.lbsConnection of pipescharge additional refrigerant.Outdoor unitIndoor unitABOutdoor unitIndoor unitABABOutdoor unitIndoor unitOil trapCAUTIONMax.Elevation: Amax=1m●In case the elevation A is more●than 5m, oil trap shoud beinstalled every 5~7mMax.
