any additional air from entering the cooling-water circuit. Also,
make sure (e.g. by rinsing beforehand) that no dirt is deposited
in the filling pipe.

Unscrew cap and slowly open vent cock (red) so that air can
escape.

Open shut-off valve -J63 and allow cooling water to flow in
slowly until bubble-free cooling water appears at the heat
exchanger drain valve.
