10.4 Filling the system
Heating circuit water quality
Carry out a fill water analysis before filling the system. This analy-
sis may, for example, be requested from the relevant water supply
utility.
To avoid damage as a result of scaling, it may be necessary to
soften or desalinate the fill water. The fill water limits specified
in chapter "Specification / Data table" must always be observed.
f
f
Recheck these limits 8-12 weeks after commissioning and
during the annual system service.
Note
With a conductivity >1000 μS/cm, desalination treatment
is recommended in order to avoid corrosion.
Note
If you treat the fill water with inhibitors or additives, the
same limits apply as for desalination.
Note
Suitable appliances for water softening, as well as for
filling and flushing heating systems, can be obtained via
trade suppliers.
!
Material losses
Never switch on the power before filling the system.
