6.2 Checking the filling pressure of the heating
installation
1. Read off the filling pressure of the heating installation
on the display (1).
2. Alternatively, read off the filling pressure of the heating
installation on the manometer.
– Even if the product is switched off, you can read
off the heating installation's filling pressure on the
manometer.
3. When the heating installation is cold and the pump
is deactivated, ensure that a filling pressure of 0.1-
0.2 MPa (1.0-2.0 bar) is displayed.
– If the heating installation is to supply several
storeys, a higher filling pressure may be required.
– If the pressure falls short by 0.08 MPa (0.8 bar), a
pressure sensor signals that the pressure is low by
making the pressure display flash.
6.3 Filling and purging the heating installation
1. Undo the automatic air vent cap (1) on the pump by one
or two rotations.
– During operation, the product purges itself via the
automatic air vent.
2. Open all thermostatic valves in the heating installation.
3. Use a hose to connect the filling/draining cock on the
heating installation to a cold-water draw-off valve.
4. Slowly open the cold-water draw-off valve and the filling
tap on the heating installation and top up with water un-
til the required system pressure is shown on the mano-
meter.
5. Close the filling tap.
6. Hold a receptacle under the end of the hose that comes
from the purging valve (1).
7. Open the purging valve (1) until the boiler has been
completely purged.
8. Purge all radiators.
9. Then re-check the filling pressure of the heating install-
ation and, if required, repeat the filling procedure.
10. Close the cold-water draw-off valve and remove the
filling hose.
11. Check all connections for tightness.
