5. Connect the heating output for the indoor module.
Caution
When connecting the heating circuit, hold the connection at the
indoor module end with a spanner to avoid piercing the pipe inside
the appliance.
Caution
In case of a direct circuit with radiators fitted with thermostatic
valves, install a differential valve to ensure flow. In the case of
standard valves, leave one radiator permanently open to allow
water to circulate and to ensure a minimum flow.
6.5.3
Connecting the safety valve drain pipe
1. Connect the outlet pipe to the waste water discharge.
Caution
The discharge pipe in the safety valve or unit must not be blocked.

Refrigeration connections
6.6.1
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 directive L. 517/2014, the installation of equipment must be
done by a certified operator whenever the refrigerant load is in excess of
two kilograms 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.
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.
