**) Option
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/pro-
cessed 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.
If the water level in the pump basin exceeds
a certain height, the solenoid valve opens
and water is routed to the sewer system via
the active carbon filter.
Suitable for dirt water
Suitable for continuous operations
With protection against dry-run
NOTICE
Pumps with excessive performance can be
throttled via the throttle valve.
