Filling for the first time
Depending on the version of the device, the reservoir for the thermal fluid can hold
between 2-14 litres (see chapter “Attachments, Technical data”). The reservoir on the
device is filled with thermal fluid from above.
Filling of the device is supported by a software program. If the fill level is too low:
▪ the pump and cooling unit will not start
▪ FILL will appear on the display and the fill level indicator will light up after the device
is switched on.

If air penetrates into the temperature control circuit while filling the
device – e.g. due to an open or damaged bleed valve – the reservoir
and also the connected consumer could empty.
Ensure that you use a sufficiently large container for the overflow pipe.
