Fig. 5.1 Checking the filling pressure of the heating system
Note
The ecoTEC appliances come with a manometer
and a digital pressure indicator.
The manometer allows you to quickly check
whether the filling pressure is in target range or
not even when the appliance is turned off.
If the appliance is in operation, you can display
the exact pressure by pressing the “-” (2).
For the heating system to operate properly, the indicator
on the manometer (
1 ) must be in the dark grey area
when the system is cold. This corresponds to a filling
pressure between 1.0 and 2.0 bar. If the pointer is in the
light grey area, please refill water.
If the heating system extends over several storeys, the
system may require a higher filling pressure.

• Insert the double check valve ( 1 ) of the filling pipe at
the cold water shutoff valve and secure the double
check valve with the spring clip (

• To fill, first open the stop valve ( 3 ).
• Open the stop valve ( 4 ), so that water flows into the
heating system. Fill the heating system as described in
Section 5.4.4.
• Close both stop valves after filling and detach the fill-
ing device by pulling the double check valve from the
cold water stop valve.
Note
Both stop valves must be closed while operat-
ing the heating system and the filling pipe must
be again detached at the double check valve.
