4.2 Checking the system pressure on the
manometer
▶
Before starting up the unit, check the installation's filling
pressure on the manometer (1). To ensure that the heat-
ing installation works correctly, a filling pressure between
1.0 and 2.0 bar should be displayed when the installation
is cold (the indicator on the manometer is then located in
the light-grey area). If the filling pressure is lower than 0.8
bar (the indicator on the manometer is then in the dark-
grey area), it must be filled with water before start-up (→
section "Filling the heating installation").
Note
If the heating installation extends over several
storeys, a higher filling pressure may be re-
quired. Ask your competent person for details.
