station must be checked by the user once a month by observing at least two operating cycles.
The interior of the sump should be checked from time to time and deposits should be disposed of
as necessary.
Maintenance of the pumping station must be carried out by qualified personnel. The following
intervals should not be exceeded:
• 6 months for pumping stations for commercial use.
• 1 year for pumping stations for domesticated use.
NOTE:
Setting up a maintenance plan avoids costly repairs, minimizes maintenance work and
achieves correct and reliable operation.
