Operation
Operating elements
1 Backwash button
2 Indicator lamp "Filtering"
3 Indicator lamp "Backwash" (orange)
4 Indicator lamp "Fault" (red)
5 Filament filter
6 Multi-channel valve
7 Overflow valve
A to collect sludge (rinse back)
B from the immersion pump
C to the high-pressure cleaner / proc-
essed water tank (filling)
Filter operations
Start the on-site immersion pump.
Switch on the power supply.
The system will automatically start the fil-
tering process when the power supply is
switched on.
Backwash
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 on-site immersion pump.
Press the backwash button.
Note
The backwash operation will be repeated
every 24 hours after the execution of the
first backwash. To set the timer for back-
washing, press the backwash button for the
desired time - the backwash operation will
be carried out daily at this time.
If no backwash is initiated by the operator,
the first backwash will begin at the first
large drop in pressure in the filament filter
and afterwards will be repeated every 24
hours.
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.
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.
Turn off the power supply.
If there is risk of frosting, then any exist-
ing water traces must be removed (see
section "Anti-freezing").
