20Installation ProcedureEnglishInstallation ProcedureCAUTION• When insulating the pipe, use non-slit insulator.2 Select the insulation of the refrigerant pipe.• Insulate the gas side and liquid side pipe referringto the thickness according to the pipe size.• Less than Indoor temperature of 30°C andhumidity of 85% is the standard condition. Ifinstalling in a high humidity condition, use onegrade thicker insulator by referring to the tablebelow. If installing in an unfavourable conditions,use thicker one.• Insulator’s heat-resistance temperature should bemore than 120°C.Pipe Pipe sizeInsulation Type(Heating/Cooling)RemarksStandard[Less than30°C, 85%]Highhumidity[over 30°C,85%]EPDM, NBRLiquid pipe Ø6.35~Ø9.52 9 t 9 t Internaltemperatureis higher than120°CØ12.7~Ø19.05 13 t 13 tGas pipe Ø6.35 13 t 19 tØ9.52~Ø19.05 19 t 25 t• When installing insulation in places and conditionsbelow, use the same insulation that is used forhigh humidity conditions.– High humidity places such as shoreline, hotspring, near lake or river, and ridge (when thepart of the building is covered by earth andsand.)– Restaurant ceiling, sauna, swimming pool etc.– – The ceiling frequently exposed to moistureand cooling is not covered.– e.g. The pipe installed at a corridor of adormitory and studio or near an exit thatopens and closes frequently.– The place where the pipe is installed is highlyhumid due to the lack of ventilation system.3 Finish wrapping insulating tape around the rest of thepipes leading to the outdoor unit.4 The pipes and electrical cables connecting the indoorunit with the outdoor unit must be fixed to the wallwith suitable ducts.Step 12 Checking the earthingIf the power distribution circuit does not have a earthingor the earthing does not comply with specifications, anearthing electrode must be installed. The correspondingaccessories are not supplied with the air conditioner.1 Select an earthing electrode that complies with thespecifications given in the illustration.2 Connect the flexible hose to the flexible hose port.• In damp hard soil rather than loose sandy orgravel soil that has a higher earthing resistance.• Away from underground structures or facilities,such as gas pipes, water pipes, telephone lines andunderground cables.• At least two metres away from a lighteningconductor earthing electrode and its cable.NOTE• The earthing wire for the telephone line cannot beused to ground the air conditioner.50 cm30 cmCarbon plasticTo grounding screwSteel coreTerminal M4PVC-insulatedgreen/yellowwire3 Finish wrapping insulating tape around the rest of thepipes leading to the outdoor unit.4 Install a green/yellow coloured earthing wire:• If the earthing wire is too short, connect anextension lead in a mechanical way and wrap itwith insulating tape (do not bury the connection).• Secure the earthing wire in position with staples.NOTE• If the earthing electrode is installed in an area withheavy traffic, its wire must be connected securely.360_AC_Outdoor_AU_Eng_EN.indb 20 2016-09-20 오후 8:00:34
