Installation without decoupling hydraulic module
–
Drain cock
–
Air separator (if required)
–
Dirt filter
–
An expansion vessel suitable for the complete hydraulic
installation
–
Expansion relief valve 0.3 MPa (3 bar)
–
Pressure gauge (recommended)
Note
If you use glycol, you must collect it at the
expansion relief valve to prevent environ-
mental pollution.
Note
Improper purging of the heating circuit may
cause pump faults due to a low flow rate
(F.532).

Remove the covering caps
(3)
from the product's hy-
draulic connections.
6.
Install a dirt filter
(9)
in the heating circuit return
between two stop valves
(8)
so that the filter can be
cleaned regularly.

(1)
and
(6)
(to be
provided on-site) with an O-ring and a stop valve to
each of the connections for the heat pump heating flow
and return.

Check the connections for tightness.
5.3.2
Connecting the swimming pool (optional)
Danger!
Risk of material damage due to a direct
connection to a swimming pool.
If the product is directly connected to a swim-
ming pool, damage may be caused by corro-
sion.
▶
Do not connect the heat pump heating
circuit directly to a swimming pool.
▶
If you want to connect a swimming pool to the heating
circuit, note the components (expansion vessels, etc.)
that are required for the installation.
5.3.3
Connecting the condensate drain pipework
Note
Observe all valid national regulations and rules.
