Venting the system
BURNS CAUSED BY HOT LIQUID
The liquid in solar systems is under high pressure and can have temperatures
of more than 100 °C.
•
Verify that the liquid has cooled down (< 50 °C at the red thermometer)
before venting the system.
Failure to follow these instructions can result in death, serious injury or
equipment damage.

Fig. 10: Function principle of vent pot
The solar liquid flows into the vent pot from the top (A). The solar liquid hits
the surface. Air bubbles are separated and rise to the top. The air collects in
the upper part of the vent pot. This air can be removed from the system by
manual venting.
1. Put the hose of the vent valve (E) into a collection receptacle.
2. Open valve (D).
- The separated air escapes from the vent pot.
3. Close the valve (D) as soon as solar liquid escapes.
