Installation
4.5 Hydraulic connections
NOTE: Material damage caused by permeable
connections!

Install connecting ducts with no connecting to
boiler connections
NOTE: Damage on installations due to bad water
quality! Heating installations can be damaged
by corrosion or calcification depending on
water quality

Respect requests for filling water in accordance
with VDI2035, or project documentation and
catalogue
Connect heating connections in the following way:

Connect returning duct to connection IN

Connect input connection to connection OUT.
4.6 Filling the installations and permeability
testing
4.6.1 Filling the boiler with heating water and
test sealing

It is necessary to test permeability before commissioning the boiler
DANGER: Injuries and/or material damage
can occur due to overpressure when testing
permeability!
High pressure can damage regulatory and safety
devices and even tank.

After filling, fill the boiler with pressure
corresponding to safety valve opening pressure.

Comply with maximum pressure in installed
components.

After permeability testing open again
shut-off valves.

Make sure that all pressure, regulation and
safety parts work correctly
DANGER:
Health hazard due to mixing
drinking water!

It is mandatory to respect regulations and
norms for avoiding mixing drinking water
(e.g. with water from the heating
installations). Comply with EN 1717.
NOTE: Material damage due to temperature
stress.
When fill the boiler in warm condition,
temperature stress can cause cracks due to
tense.

Fill the boiler in cold condition (temperature of input
duct must be 40 °C maximum).

Fill the boiler only via quick valve on the pipeline
installation (returning duct) of the boiler

Check the sub -pressure of expansion dish

Open the faucet for filling/emptying

Slowly fill the boiler. Monitor pressure increase

When working pressure is reached, close the faucet

Execute air vent of the installation through valve on
radiator

When working pressure decreases by air vent, water must be
re-filled

Test permeability in accordance with local regulations

After permeability testing, open all elements you
have closed due to filling

Check if all safety elements work correctly

If the boiler is tested on permeability and there were not
spotted any leaking, then adjust correct working pressure.

Remove hose from the filling/emptying faucet

Enter values of working pressure and water quality into
instructions for handling.
With first or repeated filling or with replacing the water

Comply with requests for filling water
4.6.2 Heating pump air vent and unlocking

This device has no circulation pump
When external pump for heating is locked, make the following:

Carefully try to unlock the pump axis using corresponding
screwdriver.
4.6.3 Boiler and installation air vent

This device has no installed air vent
.

On the installation must be installed air vent
.
