Troubleshooting
Operation
We recommend programming the filter so that
the device is backwashed at least once a month to
prevent foreign particles from adhering to the filter
element (more frequently for higher levels of soiling;
factory setting every 7 days).

The filter needs regular check of tightness, as well
a carry out backwash every second month.

If the unit malfunctions during the warranty
