English 9
Proceed as follows to subsequently change
the filter tension:
Î Turn the tightening lever towards the left
till the lever slightly bends it to show the
correct pre-tension.
Î Pull the unlocking lever towards the
front and turn the tightening lever further
towards the left till the unlocking lever
locks in in the next nose.
Î Turn the lever of the multi-channel valve
in "FILTRATION" position.
Note
After longer idling times it takes a lot of ef-
fort to activate the multi-channel valve.
Î Check filter pre-tension.
Î Check whether the drain screw has
been fitted and tightened.
Î Start the pump in the building.
Note
During normal operations, you must back-
wash the filter at least once daily. The sys-
tem does not release any processed water
during the back-rinsing process..
During backwash, the dirt collected in the
filament filter is removed. To do this, the fil-
ament filter is rinsed in the reverse direc-
tion. According to the local regulations, the
rinsed out dirt is either directed into the
sludge collection of the recycling system,
an existing disposal chain or the drainage.
Î Start the pump in the building.
Î Turn the lever of the multi-channel valve
in "RÜCKSPÜLEN/BACKWASH“ posi-
tion.
Î Loosen the filament filter by turning the
tension lever in the anti-clockwise direc-
tion.
Î Wait for 30 seconds.
Î Tighten the filament filter and loosen it
immediately.
Î Repeat ten times this process of waiting
for 10 minutes - tightening - loosening.
Î Reset the filter pre-tension.
Î Turn the lever of the multi-channel valve
in "ERSTFILTRAT/RINSE“ position.
Î Wait 2 minutes
Î Turn the lever of the multi-channel valve
in "FILTRATION" position.
If the high-pressure cleaner or the washing
system does not use up the water, the proc-
essed water is circulated to avoid foul
odour.
Note
The immersion pump can be periodically
switched on/off during non-operating hours
(for e.g. at night, over the week-end) to low-
er the operating hours. For this you can
connect the immersion pump via a timer to
the power supply.
The plant must be operated in frost-free
rooms. During frost, put the system out of
operation and remove all traces of water:
Î Loosen the drain screw.
Î Loosen the screws of the plastic pipe.
Î Let the system dry-run.
Î Switch off the building pump.
Î If there is risk of frosting, then any exist-
ing water traces must be removed (see
section "Anti-freezing").

The following section describes the flow-
path of the water in different positions of the
multi-channel valve.
In filter operations, the water flows via
– Immersion pump
– Multi-channel valve in "FILTRATION"
position
– Filter (flow direction of filtering)
– To the high-pressure cleaner/proc-
essed water tank
During backwash, the water flows via
– Immersion pump
– Multi-channel valve in position RÜCK-
SPÜLEN/BACKWASH"
– Filter (against flow direction of filtering)
– To the sludge collector
During final rinse the water flows via:
– Immersion pump
– Multi-channel valve in position ERST-
FILTRAT/RINSE
– Filter (flow direction of filtering)
– To the sludge collector
This position is not required for operating
the system.
– Suitable for dirt water
– Suitable for continuous operations
– With protection against dry-run
The bases of a safe operating of the equip-
ment is thr regularly maintenance accord-
ing to the following maintenance plan.
Use only original parts of the manufacturer
or part suggessted by him, such as
– parts and wearing parts,
– accessories parts,
– operating materials,
– cleaning agents.
Danger
Risk of accident while working on the unit.
During all tasks
Î Turn off the water supply; close the wa-
ter tap
Adjust the filter pre-tension
