SHUTDOWN/DISPOSAL

7. Shutdown/disposal
• All work must be carried out with the greatest
care.
• Proper protective clothing is to be worn.
• When working in pump chambers, it is essential
to comply with the corresponding local protective
measures. A second person must be present for
safety reasons.
• Lifting equipment in perfect technical condition
and officially approved load-bearing equipment
must be used for transporting 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
of up to 100°C during operation. There is a
risk of burns! Check the temperature before
starting the deactivation. A guard may need
to be installed under certain circumstances.
In order for the lifting unit to be taken out of
service correctly, the two solids separation reser-
voirs must be emptied completely. Two complete
pump cycles must be run through to this end.

1. Wait until the first pumping procedure has started
and been run through completely.
2. Now close the gate valve in the inlet of this solids
separation reservoir.
3. Wait until the second pumping procedure starts
and has also been run through completely.
4. Close the gate valve in the main inlet.
5. Switch the switchgear to standby mode.
6. Switch off the system at the main switch.
Secure the unit against being unexpectedly
switched back on!
7. Close the gate valve on the pressure side.
8. Now it is possible to start the work of removal,
maintenance and putting into storage.

7.2. Removal

DANGER due to toxic substances!
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 a suitable point!
• The protective clothing and cleaning cloths
must be disposed of acc. to waste code
TA 524 02 and EC Directive 91/689/EEC, or acc.
to local directives!
Prior to removal and placement in storage, the
following maintenance tasks must be carried out
in accordance with the "Maintenance and repair"
chapter:
• Cleaning the solids separation reservoirs
• Clean the collection reservoir and the supply box/
distributor
Furthermore, the lifting unit must be flushed out
so that the pipework can also be cleaned.
1. Carry out the maintenance tasks in accordance
with the "Maintenance and repair" chapter.
2. Open the gate valves to the solids separation
reservoirs in the pressure pipe.
Attention! The gate valve in the inlet pipe must
remain closed!
3. Dismantle the cover on the supply box/distribu-
tor.
4. Restart the system: Switch on the switchgear and
switch over to Automatic mode.
5. Fill the collection reservoir with clean water using
a hose through the distributor.
6. Proceed as described in the section "Switching off
the unit" and take the system out of operation.
The lifting unit is flushed with clean water via the
two pumping procedures.
7. Remove the water hose and mount the cover on
the supply box/distributor.
8. Detach the inlet pipe on the flange.
9. Detach the pressure pipe.
10. Detach the ventilation connection and pull off
the ventilation line upwards from the connecting
piece.
11. Dismantle the diaphragm hand pump, if present,
from the lifting unit.
12. Once all connections have been disconnected,
release the anchoring points of the lifting unit in
the floor.
13. Now the lifting unit can be pulled carefully out of
the pipework.
14. Clean and disinfect the exterior of the lifting unit
thoroughly
15. Clean, disinfect and tightly seal all of the connec-
tion pipes.
