Adjust the filter pre-tension
Proceed as follows to subsequently change
the filter tension:
Turn the tension lever to the left until the
lever reaches the stop.
Pull the unlocking lever towards the
front and turn the tightening lever to-
ward the right until the unlocking lever
locks in in the next nose.
Filter operations
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.
Check filter pre-tension.
Start the pump in the building.
Backwash
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.
Start the pump in the building.
Turn the lever of the multi-channel
valve in "RÜCKSPÜLEN/BACKWASH"
position.
Loosen the filament filter by turning the ten-
sion lever in the anti-clockwise direction.
Wait for 30 seconds.
Tighten the filament filter and loosen it
immediately.
Repeat ten times this process of waiting
for 10 minutes - tightening - loosening.
Reset the filter pre-tension.
Turn the lever of the multi-channel
valve in "ERSTFILTRAT/RINSE" posi-
tion.
Wait 2 minutes
Turn the lever of the multi-channel
valve in "FILTRATION" position.
Processed water circulation
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.
Maximum interval increment: 1 hour.
Frost protection
The plant must be operated in frost-free
rooms. During frost, put the system out of
operation and remove all traces of water:
Pull out the hoses.
Let the system dry-run.
Shutdown
Switch off the building pump.
If there is risk of frosting, then any exist-
ing water traces must be removed (see
section "Anti-freezing").
Transport
Caution

weight of the appliance when you transport it.
When transporting in vehicles, secure
the appliance according to the guide-
lines from slipping and tipping over.

Functional description
The following section describes the flow-
path of the water in different positions of the
multi-channel valve.
