MAINTENANCE
Maintenance and inspection of this product must be carried
out in accordance with EN 12056-4. To ensure continued reli-
ability of service, we recommend that you take out a service
contract.
NOTICE! The maintenance of the sewage lifting station and
maintenance measures are carried out by specialists at inter-
vals of 3 months in commercial premises, multi-family homes
in 6 months or 12 months in family homes.
WARNING!
Before carrying out any works: disconnect the pump and the
controls from the mains and take steps to ensure that they
cannot be energized again.
WARNING!
Check the cable for mechanical or chemical damage. Damaged
or kinked cables must be replaced by the manufacturer.
We recommend that the following works be included in the
service:
1. Check the connection points for watertightness and in-
spect the areas surrounding the unit and the fittings.
2. Operate the shut-off valves and check that they move eas-
ily. Adjust and grease them if necessary.
3. Open and clean the swing-type check valve; check the seat
and valve (ball)
4. Clean the pump and the pipes where they connect to the
unit; check the impeller and the bearings.
CAUTION!
Worn impellers can have sharp edges.
5. Oil check. If necessary top up or change oil (if oil chamber
available).
6. Clean the inside of the tank (as necessary, or if especially
required); remove any grease, for example.
7. Check the condition of the collecting tank.
8. Flush the system through with water once every 2 years.
9. Inspect the electrical section of the unit. The control unit
itself is maintenance-free, but if a rechargeable battery is
fitted, then it should be checked regularly to ensure that it
is in good working order. To do so, unplug the unit from the
mains and lift the float of the level controller slowly by hand
and hold it there until the alarm is triggered.
10. In addition, clean the float if necessary.
When all the servicing tasks have been performed, carry out a
test run and then put the unit back into operation. The service
must be documented, giving details of the important data and
of all the tasks carried out.
