7. Installation of the sump extension (ac-
cessory)
Install the sump extension as described in
the instructions supplied.
After this, continue filling in the excavated
hole. If the upper flanged area cannot be
then suitable meas-
compacted to 97% D
Pr
ures must be taken (such as filling lean con-
crete under the flanged area) to prevent the
sump from subsiding.
8. Installation of the cover (accessory)
Please level out any unevenness in the con-
crete cover seating using cement mortar.
9. Installing the pump
Fix the pressure pipe with the coupling
valve to the discharge branch of the pump.
In the case of pumps from MultiCut 25/2 M
upwards, a transverse joint is screwed on
between the pump and the coupling valve to
provide extra stability.
ATTENTION! Before fitting the pump, remove
any soil, gravel or sand inside the sump.
Before taking into service for the first time
and after any maintenance to the pump,
grease the seal in the coupling valve with
acid-free grease to facilitate dismantling the
valve after long maintenance intervals.
When you insert the pump, ensure that the
chain always leads straight downwards, as
otherwise the pressure pipe assembly can
jam at the guide rail and not engage properly.

ATTENTION! Ensure that the ball-type shut-
off valve is closed before lowering the pump.
After this, lower the pump and connect it up.
Finally, open the ball valve again.
ATTENTION! In the case of pump chambers
in pressure drainage systems which have not
been taken into service, the ball-type shut-
off valve must remain closed.
Ball valve "open"
Ball valve "closed"
MAINTENANCE
We recommend that you service the equip-
ment in accordance with EN 12056-4 and EN
60074-19.
Before carrying out any works: dis-
connect the pump and the controls
from the mains and take steps to
ensure that no one else can reconnect them
to the power supply.
Check the rubber hose for me-
chanical or chemical damage. A
damaged or kinked hose must be
replaced.
When using a chain to lift the
pump, please observe the relevant
national regulations regarding ac-
cident prevention. Lifting gear must be
checked regularly by an expert in accordance
with the legal regulations.
To carry out maintenance work on the non-
return valve or the pump, the ball-type shut-
off valve must be closed and the complete
pressure pipe assembly taken out of the
pump chamber together with the pump.
