unit into the socket marked 24 V DC. Plug in power
supply unit with plug (3) to mains power point.
As soon as the power is connected, the first back-
washing cycle is performed automatically.
The illuminated display is activated during back-
washing.
The default factory setting

appear first. The filter is capable of backwashing
hourly, daily or weekly up to 56 days.
It is recommended to program the filter so that the
device is backwashed at least once a month to
avoid the build-up of foreign particles on the filter
screen, or more frequently if required.
In case of power loss the filter will backwash au-
tomatically once the power supply is reconnected.
