MAINTENANCE AND REPAIR English
• Lifting equipment in perfect technical condition
and officially approved load‑bearing equipment
must be used for lifting and lowering the lifting
unit.
RISK of death due to malfunction!
Lifting gear and equipment must be in
perfect technical condition. Work may only
commence if the lifting equipment has been
checked and found to be in perfect working
order. If it is not inspected, fatal injuries may
result.
7.1. Switching off the unit
BEWARE of burns!
The motor housing can reach temperatures
well in excess of 40 °C. There is a risk of
burns! After switching off, first let the motor
cool down to ambient temperature.
1. Close the gate valve in the inlet pipe.
2. Drain the collection reservoir. To do this, switch
the unit on in manual operation using the manual
button for no more than 20 seconds.
3. Switch the lifting unit to standby mode via the
switchgear.
4. Pull the plug out of the socket.
5. Secure the unit against being unexpectedly
switched back on!
6. Close the gate valve in the pressure pipe.
7. Now it is possible to start the work of removal,
maintenance and putting into storage.

During removal, there is potential for contact
with fluids that represent a health hazard. The
following points must be observed without
fail:
• Wear appropriate full-body protection as well
as protective goggles and mouth protection.
• Immediately wipe up drips.
• All components must be cleaned and disin-
fected!
• Channel the flushing water into the sewer
system at suitable points!

the pipework.
11. Flush through the lifting unit with clean water and
disinfect it
12. Firmly close all connecting pipes, clean and disin-
fect them.
13. Clean the operating space and disinfect it if
necessary.
7.3. Return delivery/storage
Lifting units that are sent back to the factory
must be cleaned to remove impurities and, if they
have been used with fluids that are harmful to
health, they must also be decontaminated.
For shipping, the parts must be packed in tear-
proof plastic bags of sufficient size in such a
manner that they are tightly sealed and leak-
proof. Furthermore, the packaging must protect
the lifting unit from damage during transporta-
tion. If you have any questions, please contact
