– Let the device cool down!

– Wait until the device is completely stopped, d. h., The fan of the electric motor and consequently the impeller no longer rotates.
– Before disconnecting lines, make sure that there is no negative pressure or overpressure in them and that no liquids can escape from the device or system!
– Observe the maintenance instructions in this operating manual.

Danger due to rotating components: Cooling fan of the electric motor.
Although all measures have been taken to reduce the existing hazards during development, there are residual risks due to fan rotation.

Protective measures against risks:
