8.5.3. Cleaning the collection reservoir and overflow
The cleaning of the collection reservoir and of
the overflow must take place in the following
sequence:
1. Collection reservoir
2. Overflow
This means that the water for the cleaning can be
taken up in the collection reservoir and disposed
of with the next pumping procedure.

4 Locking lever of the clamp
A cleaning opening is fitted to the front side of
the collection reservoir. It is possible to clean the
collection reservoir through this opening.
1. Detach the fixation on the clamp.
2. Open the clamp and remove the cover.
3. Clean the collection reservoir with a water jet.
The filling level sensors must not become
damaged during cleaning work. Do not point a
strong water jet directly at the level sensor!
4. Attach the cover once more and fasten it with the
clamp.
5. Tighten the screw for the fixation of the clamp
once more.
Max. tightening torque: 14 Nm

3 Screwed connection
The cover on the supply box/distributor can be
removed for the cleaning of the overflow.
1. Undo the screwed connections on the cover of
the distributor/supply box.
2. Remove the cover.
3. Clean the supply box/distributor with a water jet.
4. Put the cover back on and screw the bolts back in.
Max. tightening torque: 10 Nm
8.5.4. Cleaning the solids separation reservoirs
The solids separation reservoirs are equipped
with two screen holders which require cleaning at
regular intervals.
At the time of cleaning it must be noted that
the water used for flushing out the screen
holders and for cleaning the solids separation
reservoirs must be collected accordingly and
properly disposed of!

1. Undo the screwed connections at the discharge
port of the sewage pump.
2. Undo the screwed connections of the pump inlet
on the solids separation reservoir.
3. Pull the pump inlet out of the pipework.
4. Remove the screen holders from the connection
port of the solids separation reservoir.
5. Use a water jet to clean the solids separation res-
ervoir, the pump inlet and the screen holders.
Attention! The sewage must be collected and
channelled to the sewer system in accordance
with local regulations!
6. Remove the shut-off ball from the solids sepa-
ration reservoir and check them for damage. The
shut-off ball is to be replaced if
• the ball is out-of-round
• there is water inside the ball
• indentations from the seal kit are to be seen.
Attention! A defective shut-off ball leads to
problems during operation.
7. Plug the screen holders back into the connection
port of the solids separation reservoir.
8. Insert the pump inlet back into the pipework
between the solids separation reservoir and the
sewage pump.
9. Fasten the pump inlet to the solids separation
reservoir and to the discharge port of the sewage
pump with the screwed connections.
Max. tightening torque: 45 Nm
8.5.5. Oil change of the sewage pump
The sealing chamber and the motor compartment
have a hole for draining and filling.
RISK of injury from hot and/or pressurised
operating fluid!
After the hydraulics is switched off, the oil is
still hot and pressurised. This can cause the
screw plug to be ejected and hot oil to escape.
There is a risk of injury or burns! First allow
the oil to cool down to ambient temperature.

1. Undo the clamp on the suction port and the
screwed connections at the discharge port of the
sewage pump.
2. Remove the sewage pump from the pipework.
