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 Recheck these limits 8-12 weeks after commissioning and f
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.

10.4.2 DHW cylinder filling
f Filling the DHW cylinder via the "cold water inlet" connection. f
f Open all downstream draw-off valves until the appliance is f
full and the pipework is free of air.
f Adjust the flow rate. For this, observe the maximum permis- f
sible flow rate with a fully opened tap (see chapter "Specifi-
cation / Data table"). If necessary reduce the flow rate at the
butterfly valve of the safety assembly.
f Carry out a tightness check. f
f Check the safety valve. f
11. Electrical connection
WARNING Electrocution
Carry out all electrical connection and installation work
in accordance with relevant regulations.
Before any work on the appliance, disconnect all poles
from the power supply.
WARNING Electrocution
The connection to the power supply must be in the form
of a permanent connection. Ensure the appliance can be
separated from the power supply by an isolator that dis-
connects all poles with at least 3 mm contact separation.
This requirement can be met by using contactors, circuit
breakers, fuses/MCBs, etc.
Material losses
!
Provide separate fuses for the two power circuits of the
appliance and the control unit.
Material losses
!
Observe the type plate. The specified voltage must match
the mains voltage.
Note
You must have permission to connect the appliance from
the relevant power supply utility.
The terminal box of the appliance is located behind the front casing
(see chapter "Preparations / Transport and handling / Removing /
fitting the front casing").
