9.2 Recommendations before installation
9.2.1 Design of the heating circuit
The heat emitters may be either low temperature (underfloor
heating, etc.), or medium temperature (warm radiator, etc.).
b
We recommend that you provide sufficient flow for the
temperature difference between flow and return to
be equal to 7 C for a underfloor heating and 15 C for
radiators.
The route of the piping will be designed to take all measures ne-
cessary to avoid air pockets and facilitate the permanent venting
of the installation. Vents must be provided at each high point of
the pipes, and on all the radiators.
b
Always leave a radiator open.
We recommend installing a drainage valve at the lowest point of
the installation.
In the case of the use of thermostatic valves, it is imperative not
to fit to all radiators, taking care to fit these valves in rooms with
high input and never in rooms where the room thermostats are
installed.
- If it is an old installation, it is essential to rinse the radiator
circuit before installing the new appliance and to add an anti-
sludge filter.
- If a component of the system is not to be installed
immediately, protect the various connections so plaster
and paint cannot compromise the seal on the subsequent
connection.
• Install the following components on the heating circuit return:
- a heating filter,
- 2 quarter-turn shut-off valves (1 each side of the filter),
- an air separator (if necessary),
- an anti-sludge filter (if necessary).
• In the case of a underfloor heating, install a security device to
prevent overheating, with manual reset (55°C) on the heating
circuit flow. Connect the overheating security device to the
glycol pump of the heat pump.
9.2.2 Design of the heat pump circuit
Installation pipework must be designed and installed to ensure
venting of air from the system is possible.
b
Ensure that the water flow rate of the water circuit
corresponds to the nominal water flow rate of the
appliance (see ¨Technical data¨ chapter).
• Install the following components on the rear section of the
heat pump:
- a filter,
- a ¼ shut –off valve on each side of the filter,
- a drain valve,
- an air separator (if necessary)
- a sludge deposit (if necessary).
• Install a ¼ turn shutoff valve in the flow of the heat pump.
i
In order to avoid the transmission of vibrations to
surrounding structures, use flexible hoses for the
hydraulic connections at least 1 metre from the heat
pump.
b Insulate the pipes with a UV- and hightemperature-
resistant insulation.
