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
.
