7 Installation
7.1 Overview: Installation
This chapter describes what you have to do and know on-site to
install the system.
Typical workflow
Installation typically consists of the following stages:
1 Mounting the outdoor unit.
2 Mounting the indoor unit.
3 Connecting the refrigerant piping.
4 Checking the refrigerant piping.
5 Charging refrigerant.
6 Connecting the water piping.
7 Connecting the electrical wiring.
8 Finishing the outdoor installation.
9 Finishing the indoor installation.
INFORMATION
If you have limited installation space, do the following
before installing the unit in its final position: "7.8.5 To
connect the drain hose to the drain" on page 40. It
requires to remove one or both side panels.
INFORMATION
Depending on the units and/or the installation conditions, it
might be necessary to connect electrical wiring before you
