Install the air vent to the highest point of the system.
Should there be more places with a risk of air pockets,
air vents should be installed also there.
It is recommended to amend the air vent with a local
pipe widening that calms down the stream and helps in
good separating bubbles from the
fl
uid (see pic. 29).
A ball valve shall be always installed under the automatic
air vent valve, so that the automatic air vent can be clo-
sed after the system commissioning. Solar liquid leaks
can be avoided in case of system stagnation.
For an ef
fi
cient removal of bubbles from the system it is
advisable to
fi
t the pump station with an air eliminator
(see Fig. 28).
