Contaminated Lifting Station Or Components - Grundfos Conlift1 Montage- Und Betriebsanleitung

9.2.1 Conlift1 and Conlift2
See illustrations on page 224.
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 Conlift.
3. Make sure that the hoses are not mechanically or
chemically damaged.
4. Remove the discharge 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.
9.2.2 Conlift2 pH+
Warning
Condensates from boilers are aggressive
as they contain acid.
Use protective gloves and safety goggles
when performing service work.
Neutralisation unit
See illustrations on page 225.
Check and clean the neutralisation unit drawer
regularly.
Make the following checks, measure the pH level
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 Conlift.
3. Check the pH value of the granulate in the
drawer with the supplied pH indicator.
4. If the drawer is empty or the pH indicator
indicates an acid level below 5, fill the drawer
with neutralisation granulate (approx. 1.5 kg).
5. Make sure that the hoses are not mechanically or
chemically damaged.
6. Remove the discharge 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.
7. If the condensate is running out of the hose,
check and clean the non-return valve.
8. Press the side-locking catch and lift off the

9.3 Contaminated lifting station or
components
If a Conlift has been used for a liquid which
Caution is injurious to health or toxic, it will be
classified as contaminated.
If Grundfos is requested to service the lifting station,
Grundfos must be contacted with details about the
pumped liquid, etc. before the lifting station is
returned for service. Otherwise Grundfos can refuse
to accept the lifting station for service.
Incidentally, any application for service, no matter to
whom it may be made, must include detailed
information about the pumped liquid.
A lifting station returned for service must always be
cleaned in the best possible way.
Possible costs of returning the lifting station are to be
paid by the customer.
