3.2 Maintenance of Filters
DAYLIFF filters need no routine maintenance other than regular
backwashing. However, over time the media will progressively clog and
become less effective. The period will depend upon the pool installation and
usage, though is normally some years. Ineffective media becomes apparent
through reduced filter efficiency and when this occurs re-charging with new
media will be necessary.
Important Note:-
The pipe connections must be correctly done as shown above. Hand tightening is
adequate for the MPV unions and under no circumstances should a pipe wrench
be used. If the union weeps, add more thread tape on the union threads and
make sure to check that the union O-Ring is in place.
