Translation of original Operating and Installation Instructions 15
 KNF recommends mechanically decoupling the pump from the
piping system. This can be achieved with flexible hoses or
pipes, for example. This prevents any oscillations of the pump
being transferred to the system.
For pumps with alternating current motors:
WARNING
Danger of injury during operation
 Take protective measures
against touching parts
which are energised (live), such as electrical
connections or windings.
 Take protective measures against touching
moving parts (e.g. fan).
Danger of damaging the pump during operation
 Take protective measures to ensure that no
foreign objects can get into the pump or pene-
trate the motor (see protection class).
