6.4.5
Installing the outdoor unit on the ground
When mounting 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.

Hydraulic connections
6.5.1
Special precautions for the connection of the heating
circuit
During connection, it is imperative that the standards and corresponding
local directives be respected.
Depending on the heating system installation, install a filter on the
heating return circuit.
Depending on the heating system installation, install a magnetic and/or
mechanical sludge collector on the heating return circuit, just before the
heat pump.
If components made from composite materials are used (polyethylene
connection pipes or flexible hose), we recommend components with an
anti-oxygen barrier.
Germany: anti-oxygen barrier according to the DIN 4726 standard.
6.5.2
Connecting the heating circuit
Heating installations must be able to guarantee a minimum flow rate at all
times.
Important
To ensure maintenance and accessibility to the various
components in the module, the hydraulic pipes have been
purposely designed with a degree of play. This play is necessary
and controlled. This pipe design guarantees the leak-tightness of
the product.
1. Make the hydraulic connections between the indoor module and the
heating circuit.
2. Install an automatic air vent at the highest point on the heating circuit.
3. Calculate the volume of water in the heating circuit and check the
volume of the appropriate expansion vessel using DTU65–11. Use the
maximum temperature of the circuit in heating mode or, failing that, a
minimum of 55 °C. If the volume of the integrated 8-litre expansion
vessel is not sufficient, add an external vessel to the heating circuit.
4. Connect the indoor module heating return by integrating the complete
tube and pressure gauge delivered with the indoor module.
