Q. The water level inside the filter chamber does not seem to be rising
and the fleece-mat is not advancing.
A. If this is a newly installed unit, it could take about a day for the initial
fleece-mat lining the filter chamber to get blocked enough to cause
an advance. In an established system check that the Mat-Advance-
length setting is at a reasonable length to cause regular advances
in the time frame you are expecting. Also check that that a long
"Scheduled-Advance" is not implemented. If all of the settings are
correct check for one the following issues that is causing the water to
completely or partially bypass the fleece-mat:
• The inlet hose is not firmly connected to the inlet port or is missing
the silicone seal.
• The inlet port plug is not correctly sealing the unused inlet port.
• The mat-retainer is not seated correctly inside the filter chamber.
• The fleece-mat inside the filter chamber has been perforated or
twisted.
