Service And Maintenance - Kessel Pumpfix F Comfort Anleitung Für Einbau, Bedienung Und Wartung

4.1 Service
The system must be checked once every
month by the operator through observation
of the switching routine for operational abi-
lity and leaks.
• Press flap closure button on control unit
• Allow water to flow in
• Wait until level-LED + pump trigger.
• Switch off water feed
• Switch off level-LED and wait for pump

Comfort: Please note that the backwater
valve must be open after the inspection has
been completed.
The pump should be checked at regular in-
tervals. If operational noises increase, pum-
ping capacity decreases or there are vibra-
tions in the pipeline system, the pump hou-
sing and impeller must be checked for any
stubborn soiling or wear.

blems should occur that cannot be elimina-
ted, please contact the specialist company
