Keep refrigerant piping as short as possible.▪ Flare connections. Connect refrigerant piping to the unit usingflare connections.▪ Insulation. Insulate the refrigerant piping on the indoor unit asfollows:A Ba dc e fb b a dc e fb b243 g 1 23 4gAB1A Gas pipingB Liquid pipinga Insulation material (field supply)b Cable tie (accessory)c Insulation pieces: Large (gas pipe), small (liquid pipe)(accessories)d Flare nut (attached to the unit)e Refrigerant pipe connection (attached to the unit)f Unitg Sealing pads: Medium 1 (gas pipe), medium 2 (liquid pipe)(accessories)1 Turn up the seams of the insulation pieces.2 Attach to the base of the unit.3 Tighten the cable ties on the insulation pieces.4 Wrap the sealing pad from the base of the unit to the top ofthe flare nut.NOTICEMake sure to insulate all refrigerant piping. Any exposedpiping might cause condensation.5.3 Connecting the electrical wiringDANGER: RISK OF ELECTROCUTIONWARNINGALWAYS use multicore cable for power supply cables.WARNINGIf the supply cord is damaged, it must be replaced by themanufacturer, its service agent or similarly qualifiedpersons in order to avoid a hazard.5.3.1 Guidelines when connecting the electricalwiringTightening torquesWiring Screw size Tightening torque(N•m)Interconnectioncable(indoor↔outdoor)M4 1.18~1.44User interface cable M3.5 0.79~0.97
