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
Risk of injury and damage! Observe the
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.

Storage

Caution
Risk of injury and damage! Note the weight
of the appliance in case of storage.
