• Make sure that the operating liquid complies with the requirements, see Operating Li-
quid Settings.
5.3 Operating Liquid Settings
The machine cannot operate without an operating liquid system. The actual scope of de-
livery is always contractually agreed upon.
The condition of both the operating liquid and the conveyed media depend on the phys-
ical conditions pressure and temperature.
At a very low pressures and sufficiently high temperatures the operating liquid can locally
transfer into the vapour phase, creating bubbles within the operating liquid. This process
is called “cavitation” and may deteriorate the machine and its performance, see
Recommended operating liquid (water) settings at various inlet pressures:
