7. Servicing the product
Always use original accessories from Grundfos to
ensure safe and reliable operation.
7.1 Maintenance
The Conlift does not require any special
maintenance, but we recommend that you check
operation and pipe connections at least once a year
and that you clean the collecting tank, if necessary.
7.2 Service
Thanks to the Conlift design, service can easily be
performed in case of malfunction or blocked pump.
7.2.1 Conlift
See illustrations on page 202 .
Make the following checks and clean the collecting
tank, if necessary:
1. Disconnect the power supply.
2. Cut off the flow of condensate from the boiler or
other application, or stop the flow of condensate
to the Conlift.
3. Make sure that the hoses are not mechanically or
chemically damaged.
4. Remove the outlet hose by turning the bayonet
coupling, and check the O-ring. The condensate
in the hose will not run out due to the non-return
valve.
5. If the condensate is running out of the hose,
check and clean the non-return valve.
6. Press the side-locking catches and lift off the
motor support. Place it in upright position.
7. Remove deposits, dirt, algae and incrustations
under running water.
