PLACING FILTER INTO SERVICE
1 Before placing filter into service, media must be soaked for at least two
hours; 24 hours for carbon filter.
2 Once media is soaked, push the recycling button
for five seconds to
start backwash.
3 You can shorten the backwash time by pushing both
■
and
buttons.
4 A few short cycle backwashes are better than a full long one as dust and
dirt will release with change of flow direction. Carbon filter requires five to
seven backwash cycles until backwash water is clear.
