7.1 - Controlling cock opening
- The gas cock must be open;
- Any valves positioned on the flow and return must be open;
7.2 - Checking central
heating plant pressure
If the pressure inside the central heating circuit drops below
0.5 bar, the visual display “N” in figure 7.1, shows
FILL
to indicate that the correct pressure must be restored.
Proceed as follows:
1.- open the device envisioned by the installer upstream
from the appliance in order to load the plant;
2.- check the pressure on the visual display “M” in Figure
7.1; it must reach the pressure of 1.5 bar (the
FILL
indication must disappear);
3.- close the device envisioned by the installer upstream
from the appliance.
ATTENTION !!! During normal operation, the
device envisioned by the installer upstream from the
appliance for loading the plant, must always remain in
the closed position.
If the pressure drops through time, restore the correct
value. This operation may have to be repeated several
times in the first month of operation to remove any air
bubbles in the plant.
