7.4 Shut-off
The shut-off with a plastic handle (see Fig.) has a square-end connection (see Fig.) under the handle after it has been pulled down. If the handle has been
removed, this square-end connection can be turned with an appropriate socket wrench, thus opening or closing the shut-off. The opening angle of the
shut-off is also visible, i.e. whether it is open or closed. Check the opening angle during the commissioning. The full opening of the shut-off is shown in
the illustration.

7.5 Manual air bleed device
A manual air bleed device (see Fig.) is located on the heat exchanger inlet on the
primary side (heating medium) for manually bleeding the heat exchanger (primary side).
Please only use a suitable tool to open the air vent! The flushing, filling and bleeding
of the system must be carried out professionally before the commissioning to ensure
that it operates properly.
