Installation of the device
4.5
Introduction of hydraulic connectors
NOTE:
Material damages caused by
throughput connectors!
Install the connection lines without connecting to
the connectors of the boiler.
NOTE:
Damages to the installation due to poor
water quality! Depending on the properties of the
water, the heating installation may be damaged
by corrosion or by the formation of limescale.
Follow the requirements for water for filling
according to VDI 2035, i.e. project documentation
and the catalog.
Connect the heating lines as follows:
Connect the return line to the IN connector.
Connect the starting line to the OUT
connector.
Check the pre-pressure of the expansion container.
Open the charging and discharging tap.
Fill the boiler slowly. Follow the pressure on the display.
4.6
Fill the installation and check the
impermeability.
Before filling the system, the boiler must be connected
to the electrical installation and switched on via the
ON/OFF switch on the bootom side of the boiler to the
STAND BY mode in order to monitor the value of
pressure in the installation.
4.6.1
Fill the boiler with water (demineralized water is
recommended) and test the welds and seals
The impermeability must be tested before putting the boiler into
operation.
DANGER:
Injuries and/or material damages
can occur by exceeding the pressure during
the testing of impermeability!
High pressure can damage the control and safety
devices as well as the tank itself.
Fill the boiler with pressure that corresponds to
the pressure of the opening of the safety valve.
Observe the maximum pressure of the built-in
components.
After checking the impermeability, re-open the
valves.
Ensure that all control and safety parts
for pressure control work properly.
DANGER:
Danger to health due to mixing
drinking water!
Be sure to follow national regulations
and norms to avoid mixing drinking water
(eg. with water from heating installations).
please follow EN 1717.

NOTE:
Material damages caused by
temperature stress.
If you fill the boiler in a warm/hot condition, the
temperature stresses can cause cracks due to
straining. The boiler will start to leak water.
Fill the boiler only in cold condition (the
temperature of starting line may be maximally
40°C).
Fill the boiler only through the quick valve on the
boiler's pipe installation (return line).
Close the tap when the operating pressure is reached.
Discharge the air from the boiler through the valve for air
discharging (
image 5 and image
6).
Discharge the air from the installation via the valve on
the radiator.
When the operating pressure is lowered by discharging of
air, the water must be refilled.
Test the impermeability according to local regulations.
After checking the impermeability, open all the items
that you closed because of the filling.
Make sure all the security elements work correctly
If the boiler is tested for impermeability and no leakage has
been detected, set the correct operating pressure
