Airstop
The Airstop with manual vent valve is used to vent the solar
installation. To ensure a perfect venting of the solar circuit,
the flow velocity in the flow line must be at least 0.3 m/s.

The air separated from the solar fluid is collected in the upper part of the Airstop
and can be released at the vent plug [F].
WARNING
Danger of scalding due to vapour escape!
The escaping fluid can heat up to more than 100 °C and cause scalding.

Carefully open the vent plug and close it again as soon as medium
escapes.
Venting the solar installation after commissioning
At the beginning, vent the solar installation daily and then weekly or monthly,
depending on the quantity of vented air. Thus, an optimum operation of the solar
installation is ensured. Check the system pressure after venting and increase it to
the specified operating pressure if necessary.
