Filter Cartridge Replacement; Troubleshooting - Pentair OMNIFILTER BF35 Manual

FILTER CARTRIDGE REPLACEMENT

The life of the cartridge depends on the water volume used and the
substances in the water. Normally the cartridge should be changed at intervals
of three to six months or less. Replace the cartridge sooner if the water
pressure at the faucet begins to drop noticeably or if you notice changes in the
taste, color, or flow of the filtered water.
NOTE: Certain types of harmless bacteria will attack cellulose material.
Cartridges containing cellulose, such as the RS15 and TO6, may seem
to disintegrate, produce a "sewer" or "rotten egg" odor, or form a black
precipitate due to bacteria. If this happens, consult OMNIFILTER Customer
Service for advice or select a different cartridge.
1. (A)
Bypass water to the filter by turning the handle clockwise
1/2 turn until it comes to a stop.
NOTE: This will shut off all water flow to the housing. Water going to the
household is not being filtered at this time. Be sure to fill a bucket of water
first so you may clean housing after it has been removed.
(B)
Remove bottom of housing by unscrewing.
2. Locate and remove large O-ring
Discard used cartridge (B) . Rinse out bottom of housing and fill 1/3 full with
water. Add 2 tablespoons of bleach and scrub cap and bottom of housing
with non-abrasive sponge or cloth. Rinse thoroughly. Lubricate O-ring
(C)
with clean silicone. Insert O-ring back into groove and smooth into
place with finger.
NOTE: This step is important to ensure proper housing seal. Make sure
O-ring is seated level in the groove.
(D)
Insert new cartridge over standpipe in bottom of housing.
3. (A)
Screw bottom of housing onto the cap and hand-tighten until snug.
DO NOT OVER-TIGHTEN. Make certain cap standpipe slips into cartridge.
(B) Slowly turn handle on housing 1/2 turn counter-clockwise to allow filter
(C)
to fill with water. Depress red pressure relief button to release trapped
air. Flush cartridge for 10 minutes, wait one hour, and flush for another 10
minutes before use. Check for leaks before leaving installation.
