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
