8. Cooling circuit connection
The heat exchanger is a compact device and contains all the parts necessary for cooling the
fluid. Only the connection tubes between the heat exchanger and the user to be cooled or the
tool are to be provided on-site. The fluid in- and outlets are to be connected using flexible
pressure tubes. No rigid pipe connections are to be created. The flow direction is marked by
arrows on the connections.
The filling of the container is done via a filling connection on the device lid.
When filling the device, observe the following:
a) Before the feed and reflux pipes are connected, the container in the device is to be pre-filled
to
the
maximum
filling
level
(see
upper
marking
on
the
filling
level
display).
The
air contained in the system can thereby escape in an optimal fashion.
b) During first filling, the pump and pump head are to be deaerated. For this,
a deaeration tube is attached to the top of the pump head and is closed off by a red
plug.
The
lid
is
to
be
removed
before
filling.
Filling
is
done
via
the filling nozzle on the casing lid. If the water level reaches the upper mark
on
the
water
level
display,
filling
of
the
device
is
complete.
The
de-
aeration tube is to be closed with the red plug.
Avoid dry running of the pump
c) At the end of the filling process, the device is to be connected to the feed and
reflux tubes as described above.
In order to pull out the plug
press the side ring of the
plug connection towards the back.
