Kalor Insert Hydro 17 Bedienungsanleitung Seite 107

Filling the Hydro Insert funding of sanitary kit
Once all the water connections, proceed to check
pressure seal by filling the Hydro Insert. During this
operation, any air in the system is released from the
automatic vent valve.
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;
