NOTICE
Vacuum pump damage caused by different cooling characteristics
For applications with short switching cycles or increased ambient temperature, there is a risk of dam-
aging the rotor after switching off temporarily.
► Always switch the oil / water cooling off together with the vacuum pump.
► For checking the cooling water flow, use a solenoid valve that only opens when the vacuum
pump is switched on.
