F To the drainage system
**) Option
Proceed as follows to subsequently change
the filter tension:
Turn the tension lever to the left until the
lever reaches the stop. Then attach it
with the unlocking lever.
Turn the lever of the multi-channel
valve in "FILTRATION" position.
NOTICE
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.
NOTICE
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. The rinsed dirt is routed to the sludge
collector of the recycling system.
Start the pump in the building.
몇 WARNING
The max. permissible flow volume during
return rinse is 2,000 l/h. Adjust flow volume
on throttle valve if necessary (order no.)
4.640-230.0).
Turn the lever of the multi-channel
valve in "RÜCKSPÜLEN/BACKWASH“
position.
Loosen the filament filter by turning the
tension lever in the anti-clockwise direc-
tion.
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.
If the high-pressure cleaner or the washing
system does not use up the water, the pro-
cessed water is circulated to avoid foul
odour.
NOTICE
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.
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.
Switch off the building pump.
If there is risk of frosting, then any exist-
ing water traces must be removed (see
section "Anti-freezing").
