3. Connect the heat exchanger with the hydraulic
unit ( Fig. 36 ).
If there are several heat exchangers in airflow
direction, connect the pipes in series.
The position of the connection points is given in
the order-specific approval drawing.
If you are in doubt about the position of any pipes
to be connected, please get in touch with our
Technical Service.

Ventilation device
For optimum ventilation of the heat exchanger, we rec-
ommend that you install suitable air separators at the
highest points of the system (e.g., above the air han-
dling unit), which reduce the airflow velocity by
increasing the cross section and can thus be ideally
used for deaerating glycol systems.
