reflex ’variomat 1’
in a single-boiler system
≤
350 kW, < 100 °C, make-up using potable water
You do not need to install any
additional cap valves in the
expansion line.
reflex ’fillset’ with integrated
system separator must be
installed upstream when
connecting to the potable
water system.
If reflex ’fillset’ is not installed
upstream, a filter for the make-
up unit with a mesh size of
≤
0.25 mm must be provided
on site.
Install expansion lines over
10 m in length in DN 32.
