Indoor/Outdoor Unit Installation Drawings
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.)
1) 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 “7 Refrigerant Piping Work” in “Refrigerant Piping Work (3)” for details.
2) It is impossible to connect the indoor unit for one room only.
Be sure to connect at least 2 rooms.
CAUTION

Level mounting base
(available separately)
If there is the danger of the unit
falling or overturning, fix the unit with
foundation bolts, or with wire or
other means.
If the location does not have good
drainage, place the unit on a level
mounting base (or a plastic pedestal).
Install the outdoor unit in a level
position. Failure to do so may result
in water leakage or accumulation.
