5.1
Commissioning
Before starting up (initial putting into service
or startup after maintenance work),
fill
the
filter with water and
vent!
–
To do this, after installation the filter is
brought to operating pressure by filling it
at the infeed point of the heating water
circuit.
–
The filter is now under water pressure.
–
The enclosed air is removed from the fil-
ter through the deaeration system. It is
advisable to carry out a trial backwash
after venting (see chapter “Discharging
the backwashing water”).
–
On the delivery status the sealing cap
(
7
), positioned on the outlet of the rapid
venter is in a “one turn open” position, to
ensure an unhindered escape of the air.
–
After backwashing and venting the filter
is ready for use.Functional description

Functional description
The heating water (
a
) flows through the built-
in rotary flange (
1
) into the filter. This flushes
the round filter brush (
2
) from below up-
wards. The dirt particles in the heating water
(
a
) settle on the round filter brushes (
2
). Gas
bubbles form in the heating water (
a
), which
are collected by the round filter brushes (
2
)
and are passed into the upper housing
chamber (
3
). The heating water is degassed
by a rapid venter (
4
) and the filtered and de-
gassified heating water (
b
) thus returns to
the heating circuit.
