Evacuating the air when filling the system
When starting the system, make sure that the
lock-shield on the hydraulic unit is open. If there
is a power black-out and the thermal valve
is already running, use its cap to press the valve shutter
and open it.
-
Open all the system’s shut-off valves (whether manual
or automatic);
- Start filling the system by slowly opening the water
tap;
- With the aid of a screwdriver, open the vent on the
uppermost coil connection (see figure below);
-
When water begins to leak out of the breather valves,
close them and continue to fill the system (as per the
rated specifications).
Check the tightness of the gaskets.
We recommend that you repeat this operation when the
device has been running for a few hours and that you
regularly check the system’s pressure.
Pay attention to the tilt of the condensate drain pipe when
it channels condensate outside the premises as shown in
the figure.
