Installing the suspension screw:Use M8 or M10 suspension screws (4,prepared in the field)(when the suspension screwheight exceeds 0.9m,M10 size is the only choice).These screws shall be installed asfollows with space adapting to air conditioner overall dimensions according to the originalbuilding structures.Wooden structureA square wood shall be supported by the beams and then set the suspension screws.New concrete slabTo set with embedded parts,foundation bolts etc.Original concrete sladUse hole hinge,hole plunger or hole bolt.Steel reinforcement structureUse steel angle or new support steel angle directly.Hanging of the indoor unitFasten the nut on the suspension screw and then hang the suspension screw in the Tslot of the suspension part of the unit.Aided with a level meter,adjust level of the unit within 5mm2Hanging boltSuspension screw Support steel angleGuide plate embedded partKnife embedded partFoundation boltPipe suspension foundation boltIron reinforcementSquare wood BeamSuspension screwspecially used by the power(centralized controller)PQYX ABCL Noutdoor unitoutdoor powerleak breakermanual switchcommunication wirecentralized controlsignal wire remote controller shielding layer should be connected togetherjunction box indoor unit(remote control grouped control)centralized controllerindoor unitearthindoor power(shielding layer as isolation)(shielding layer as isolation)(shielding layer as isolation)communication wireshield layer earthcentralized control signal wire earthThe shielding layer should beconnected together(shielding layer as isolation)leak breakermanual switch(remote controller)indoor unitOK NOBCBCBCBC(Fig. 2)OK OKPQPQPQPQ(Fig.1)OK OKXYXYXYXYIndoor unit installation6The indoor and outdoor units should use separate special power lines.The leak breaker and indoor switch using the same outdoor unitshould use the same power.Indoor powerThe remote controller wire is polarized 3-core wires.The grouped remote controller wire (between the indoorand indoor units) is polarized 2-core wires. (Fig. 2)Central controller communication wiringThe centralized controller communication wire are non-polarity 2-core wires.To prevent electromagnetic disturbance, please useshielded wires.Remote controller wiring(Fig.1)The remote controller wire is low voltage circuit, which should not be connected to 220-230Vor 380-400V power line. It should not share the same wire pipe with the power cable.The wire is round 3-core chielded wire, which can be extended to 200m if the diameter is0.75mm2 and extended to 500m if the diameter is 1mm2.Remote controller wiringWiring should be done according to the number of the block terminal .....11Electrical wiring
