Do not connect the embedded branch piping and the outdoor unit when only carrying out piping work without connecting
the indoor unit in order to add another indoor unit later.
Make sure no dirt or moisture gets into either side of the embedded branch piping.
See “6 Refrigerant Piping Work” for details.
It is impossible to connect the indoor unit for one room only. Be sure to connect at least 2 rooms.
For installation of the indoor units, refer to the installation manual which was provided with the units.
(The diagram shows a wall-mounted indoor unit.)
