The numbers in (parentheses) are the chapter numbers in thetable of contents of the installation manual.*1 Do not operate the air conditioner (run the compressor) before the address to the hot water module is fixed.Doing so will cause the heat exchanger in the hot water module to freeze, rupture, and leak water.*2 Set DIP switch 4 of SW09 on the P.C. board of the header outdoor unit to "ON" (factory default is "OFF").The VRF system will be stopped to avoid water freezing when the power supply is disconnected.NOTEBefore you run the compressor, always confirm that the hot water module is operable (power on, address fixed,communication wiring complete).Failure to do this will cause the heat exchanger in the hot water module to freeze, rupture, and leak water.CheckInstallation workIs the equipment attached to the legs with bolts?
