Filling and venting with >Sight glass< [23]
PROCEDURE
For temperature control units with
>Bypass valves<
[62], verify that they have been completely
opened.
Check that a hose was installed at the
>Overflow<
[12] (if present). The other end of the hose
must be inserted in a suitable collecting container. Excess thermal fluid will leak at this point
when the temperature control unit is overfilled. Hose and container must be compatible with the
thermal fluid and its temperature.
Open the
>Sight glass cover<
[24]. This makes filling easier as it prevents an air cushion from
forming in the
>Sight glass<
[23]. No thermal fluid may leak from the
>Sight glass<
[23] when fill-
ing!
Slowly
fill suitable thermal fluid into the open application. The thermal fluid flows via the
>Circu-
lation return<
[2] into the temperature control unit and via the
>Circulation flow<
[1] back to
the externally open application. Thereby the air in the temperature control unit reaches the out-
side. Follow the instructions for the proper disposal when cleaning filling accessories.
