5.8.5
Installing the outdoor unit on the ground
When installing on the ground, a concrete base must be installed, with no
rigid connection to the building served to avoid the transmission of
vibrations. Position a rubber floor support.
The data plate must be accessible at all times.
1. Dig a run-off channel with a pebble bed.
2. Install a concrete base frame with a minimum height of 200 mm
capable of bearing the weight of the outdoor unit.
3. Install the outdoor unit on the concrete base frame.

Refrigeration connections
5.9.1
Preparing the refrigerant connections
Danger
Only a qualified professional may carry out the installation in
conformity with current legislation and standards.
To allow exchanges between the indoor module and the outdoor unit, fit 2
refrigerant connections: flow and return.
Pursuant to European Regulation 517/2014, the equipment must be
installed by a certified operator whenever the refrigerant load is in excess
of 5 tonnes of CO
2
equivalent or when a refrigerant connection is
necessary (the case with split systems, even when fitted with a quick
coupling device).
1. Install the refrigerant connection pipes between the indoor module
and the outdoor unit.
For connection on the lower section, use the refrigerant hoses
supplied with the appliance.
For connection on the upper section, use the refrigerant hoses from
the EH978 package.
Important
To avoid noise from pipes vibrating against each other on the
connection plate, leave a space between the pipes during
connection or insulate them with noise-damping rubber or other
insulation.
2. Respect the minimum curve radii of 100 to 150 mm.
3. Adhere to the minimum and maximum distances between the indoor
module and the outdoor unit.
4. Cut the pipes with a pipe cutter and deburr.
5. Angle the opening in the pipe downwards to ensure no particles can
get inside, while preventing oil traps.
6. If the pipes are not connected immediately, plug them to prevent
moisture from entering.
