• For gas-rich water from the system.
• For degassed water into the system.
LIS Level sensor
Single boiler system ≤ 350 kW, water temperature < 100 °C.
• Connect the Reflex Fillset with integrated system separator upstream
when using mains water for make-up.
• If you don't connect a Reflex Fillset upstream, use an "ST" dirt trap with a
mesh size ≥ 0.25 mm for the make-up.
 Note!
The quality of the make-up water must comply with the applicable
standards such as VDI 2035.
– If you cannot achieve this quality, use the Reflex Fillsoft to soften
the make-up water from the mains water network.

District heating water is particularly suitable as make-up water.
• Water treatment is not necessary.
• Use an "ST" dirt trap with a mesh size ≥ 0.25 mm for the make-up.

Make-up with water via a softening system.
• Always integrate the device in the "V" main volume flow to ensure
degassing the system water. It is the system side in systems with central
return flow admixture or hydraulic switching points. The vessel of the heat
generator must be fitted with an individual protective device.
• When using Reflex Fillsoft softening systems, always install the Fillset
Impulse.
