Sludge trap servicing
Check the sludge trap and pumping station (option) together.
The sludge level in the sludge traps must be regularly checked
using a measuring disc (inspection set for separating systems).
This is based on the own-monitoring directive (interval depending
on the amount of sludge present). The sludge trap must be emp-
tied by an approved disposal company when 50 % full. The dis-
posal process can stir up sludge that can clog the coalescence
separator (option) or the insertion-sieve boxes.
1. Fill the sludge trap with fresh water after sludge disposal to
prevent a shortage of water in the system.
2. Check the coalescence separator (option) and the insertion-
sieve boxes for soiling over a few days after sludge disposal.
Pumping station (option) servicing
Check the sludge trap and pumping station (option) together.
If necessary, drain and clean the pumping station:
1. Set the pumping station pump to Manual mode/Off.
2. Have the pumping station drained by an approved disposal
company.
3. Remove any deposits from the pumping station if present.
4. Fill the pumping station with fresh water until the pumping sta-
tion pumps are covered.
5. Set the system into Automatic mode.
Insertion-sieve box servicing (standard version)
The insertion-sieve box consists of the insertion sieve and the
baffle plate/immersion wall. The insertion-sieve box is installed in
the discharge channel of the sludge trap upstream of the
1st biological basin and protects the immersion pump from
coarse dirt particles. The insertion-sieve box must be checked
weekly for soiling during operation in order to prevent water from
backing up in the sludge trap.

1. Pull the insertion-sieve box out of the shaft and set it down on
a suitable surface.
2. Clean the insertion-sieve box with a brush.
Biological stage servicing
Note
The aeration units in the stages must be checked for formation of
coatings and deposits after 1-2 years. The pre-treatment sludge
trap may need to be evacuated and disposed of. This work can
only be performed by Customer Service. Contact your customer
service partner responsible regarding this.

Check the discharge shaft of the sludge
trap for leaks
After completely draining/cleaning the
system, check the following points:
– Presence and completeness of the
documentation (approval certificates,
drainage plans, operating and service
manuals)
– Operational log book and sludge dis-
posal certificates
– Structural condition and leak-free
state of the system, especially the un-
derground system components
– Condition of the fitted components
and electrical equipment
– Actual waster water processed (ori-
gin, volume, contamination load,
washing and cleaning agents used,
operating materials and auxiliary ma-
terials) and supplementary water vol-
ume
– Check the operational log book for
completeness and plausibility (target-
actual comparison)
– Check the performance of the system
with regard to the waste water volume
and contamination load
– Replace the control head battery
(CR2031)
– Replace the SPS M241 battery
(CR2031)
