Instructions on commissioning, maintenance, and troubleshooting for auroSTOR 0020111119_02

6.2.4 Venting the solar circuit

Danger!

Risk of burns and scalds resulting from
escaping hot steam!

Hot steam can discharge from automatic
air vents which are not shut off if the sys-
tem is
in stagnation.

Use automatic air vents with a
manufacturer's release to at least 150 ºC.

Shut off the automatic air vents when
operating the system.

Caution!

Malfunction due to air vents that are not
shut off!

Vapourous solar fluid can escape from
automatic air vents which are not shut off
whilst the system is in stagnation. The loss
of solar fluid results in functional problems.

Close all automatic air vents once ven-
ting is complete.

Caution!

Malfunction due to unsuitable air vents!

Unsuitable air vents can be destroyed in
solar mode.

Only use Vaillant automatic air vents
with
a manufacturer's release to at least
150 ºC.
