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.)
CAUTION
• 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" on page 11 for details.
• It is impossible to connect the indoor unit for one room only. Be sure to connect at least 2 rooms.
NOTE:
The DHW generator for Multi or the Hybrid for Multi are considered as one room connection.
For the correct combination see the combination table and the installation manual of the DHW generator for Multi or the Hybrid
for Multi.
