The circuits must be adjusted to suit local conditions.
reflex ’variomat’
Assembly
12
Notes for the installer
’variomat’ must always be
integrated in the main flow
in order to be able to degas
a representative partial flow.
In the case of central return
admixture, this is the system
side. The boiler will then be
individually protected.
If the capacity of reflex ’fillset’
is exceeded (k
VS
= 1 m³/h),
a suitable connection group
must be provided on site as
an alternative in the make-
up line. The filter may have
a maximum mesh size of
0.25 mm.

Notes for the installer
In the case of water
treatment systems,
reflex ’fillset’ with system
separator and water meter
is installed upstream of the
softening system.
Provide individual protection
with ’reflex’ in the case of
multiple boiler systems.
Several VF secondary
vessels can be
connected.
