Functional description
The following section describes the flow-
path of the water in different positions of the
multi-channel valve.
FILTRATION
In filter operations, the water flows via
Immersion pump

UMWÄLZUNG/RECIRCULATION
This position is not required for operating
the system.
Function of active carbon filter
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.
