3.
Open the plugs
(2)
and then connect the filling/draining
cock connection to a heating water supply in accord-
ance with the relevant standards.
4.
Open the heating water supply.
5.
Open all thermostatic radiator valves.
6.
If necessary, check that both service valves on the
product are open.
7.
Slowly open the filling/draining cock
(1)
so that the wa-
ter flows into the heating installation.
8.
Open the air separator
(3)
and wait until the water flows
out of the air separator without bubbles.
9.
Purge all of the radiators until the entire heating installa-
tion is filled with water.
10. Close all purging valves.
11. Use the manometer
(4)
to monitor the rising filling pres-
sure in the heating installation.
–
To optimise the purging, the pressure should be lim-
ited in such a way that it lies in the first third of the
grey display field on the manometer. Once the pur-
ging procedure is complete, the digital manometer
can be used to set the hydraulic pressure depend-
ing on the distribution network (required feed head,
multilevel installation, etc.).
12. Fill it with water until the required filling pressure is
reached.

Caution.
Risk of damage to the product
▶
Protect all of the product's electrical
components before you use the air
separator.
▶
Check whether the air separator re-
mains leak-tight after it has been used.
▶
Use the air separator on the heat exchanger only if
problems occur with the filling.
