DANGER : Injuries and/or material damages
can occur with overpressure when testing
watertight!
High pressure can damage regulatory and
safety devices and reservoir.

After filling with water set the boiler on
pressure that is equal to the opening
pressure of safety valve

Comply with maximum pressure of
installed components

After testing sealing, open again closing
valves

Make sure that all pressures, regulatory
and safety parts work correctly
DANGER: Health threat due to mix of drinking
water!

It is demanding to respect state norms and
regulations on avoiding mix drinking water
(with water from heating installations)

Comply with EN 1717
NOTE: Installation damage due to bad quality
of water! Heating installation can be damaged
by corrosion or scale depending on water
characteristics.

Comply with filling requests for water
according to VDI 2035 or project
documentation and catalogue
NOTE: Material damage due to temperature
tension.

If you fill the boiler in hot condition,
temperature tension can cause cracks
due to tensions. Boiler will start to leak

Fill the boiler only in cold condition
(temperature of empty duct can be max
40 °C)

Fill the boiler only through quick valve on
pipe installation (return line) of the boiler
4.7
Filling the installations and watertight
testing
The eBasic boiler does not contain a manometer, so
when filling the installation with water, the pressure must
be monitored on the manometer installed on the heating
installation
.
4.7.1 Filling the boiler with heating water and
sealing test
Waterproof should be tested prior to put on the boiler.

The installation should be vented via valves on the
radiators

Open the filling and emptying tap

Slowly fill the boiler. In doing so, monitor the increase in
pressure

When the operating pressure is reached, close the tap.

Bleed the installation via the valve on the radiator

When the operating pressure drops by venting, the water
must be topped up

Carry out a leak test in accordance with local regulations

After testing for leaks, open any items that have closed
due to filling

Check that all safety components are working properly

If the boiler has been tested for leaks and no leaks have
been observed, set the correct operating pressure

Remove the hose from the filling and emptying tap

Enter the operating pressure and water quality values in
the Operating Instructions
During the first filling of repeated filling or when change
the water

Comply with requests for filling water
4.7.2 Heating pump air emission and de-blocking
This device does not have a circulating pump in it.
When the external heat pump is blocked, do the following:
•
Carefully try to unlock the pump shaft with a suitable
screwdriver
4.7.3 Boiler and installation air emission
• This unit does not have built-in venting.
• Ventilation must be installed on the installation.
