▪

Charging refrigerant.

▪

Connecting the electrical wiring.

▪

Finishing the outdoor installation.

▪

Finishing the indoor installation.

INFORMATION

For installation of the indoor unit (mounting the indoor unit, connecting the
refrigerant piping to the indoor unit, connecting the electrical wiring to the indoor
unit …), see the installation manual of the indoor unit.

7.2 Opening the units

7.2.1 About opening the units

At certain times, you have to open the unit.
