The filling pressure of the system WHEN COLD must be
1 bar.
During operation, if the system pressure drops (due to
evaporation of dissolved gases in the water) to values
lower than the minimum indicated above, the user must
use the filling tap to bring the pressure back up to its
normal pressure.
For proper operation of the Hydro Insert when hot, the
pressure in the Hydro Insert must be 1,5 bar.
Replenishment of the System
The replenishment has to be slowly carried out in order to
let the air bubbles flow out through the right oulets that are
placed on the heating system.
In heating systems with a closed circuit the loading cold
pressure of the system and the inflation pressure of the
expanding vase must correspond.
During the heating-season the user must regularly check
the circulating water level in the expansion vase.
The content of water in the system of recirculation must
be stable hold. Experiences show that the user must
regularly check the water level every 14 days in order to
maintain a stable water content.
The replenishment process must be carried out in case
of necessity of more water when the Hydro Insert has
cooled down. These preventive measures aim to prevent
the insurgence of thermic stress of the steel body of the
Hydro Insert.

You must not mix water of the
heating system with antifreeze
or anticorrosion substances in
wrong concentrations. This could
ruin the seals and provoke the insurgence
of noises while operating. The producer
refuses any responsibility for damages
towards persons, animals or things if this
warning will not be respected.
The loading valve is required and must be provided in
the hydraulic system.
This operation must be carried out with caution following
these steps:
• open the vent's valve of the radiator ,of the Hydro Insert
and the system;
• gradually open the filling tap of the system checking
that the automatic vent's valves, placed on the system,
are regularly working;
• close the vent's valves of the radiators as soon as the
air flows out;
• check through the pressure gauge placed in the system
that the pressure is reaching 1 bar (this is required only for
systems with closed vase, you have to look for local rules
that allow it)
• close the filling tap of the system and then let the air flow
out again through the vent's valve of the radiator;
