Filter Cartridge Replacement; Troubleshooting - Pentair OMNIFILTER CBF1 Installation Instructions Manual

WHEN TO CHANGE THE CARTRIDGE
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 400 gallons 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 TO1 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
OMNIFILTER cartridge.

FILTER CARTRIDGE REPLACEMENT

Filter cartridges for the CBF1 will last about 1,000 gallons and the
CBF3 will last about 400 gallons before they need to be replaced.
Filter cartridge life varies depending on usage, and/or water
conditions. Changes in taste, color, and flow of the water being
filtered indicate that the cartridge should be replaced.
NOTE: Read all instructions before replacing filter cartridge.
A. Turn off cold water supply and open the drinking water
faucet to release pressure from system.
B. Unscrew and remove bottom of filter housing. Locate and
remove large o-ring, wipe clean of lubricant, and set aside.
C. Discard used filter cartridge. Using a non-abrasive sponge
or cloth, scrub the bottom of filter housing, o-ring groove,
and cap with dish soap and warm water. Rinse thoroughly.
Fill bottom of the housing 1/3 full with water. Add 1
tablespoon of household bleach and scrub to disinfect.
D. Lubricate o-ring with silicone grease. Insert o-ring in groove
and press into place.
NOTE: This step is important to ensure a proper housing
seal. Make certain each o-ring is seated level in its groove
or a leak may occur.
E. Screw bottom of housing with bleach water onto cap
without filter cartridge and hand-tighten.
DO NOT OVER-TIGHTEN.
F. Turn on water supply. Let faucet run for about 10 seconds,
then turn off faucet and let stand for 20-30 minutes.
G. Turn on faucet and allow bleach water to run out
(about 3-5 minutes).
H. Turn off water supply to system and open faucet to release
pressure. Remove bottom of housing and empty water.
I. Insert filter cartridge into bottom of filter housing.
J. Screw bottom of housing onto cap and hand-tighten.
DO NOT OVER-TIGHTEN. Make certain cap standpipe slips
into cartridge.
K. Open water supply and turn on drinking water faucet to
release pressure in system. Let faucet run for 5 minutes
to remove trapped air and carbon fines. Check system for
leaks before leaving installation.
NOTE: It is recommended that you run the tap at least 20
seconds prior to using water for drinking or cooking purposes.
NOTE: Initially, filtered water may appear cloudy. If you set
a glass of water on a level surface, you should be able to
watch the cloudiness disappear from the bottom of the glass
upwards. This harmless cloudiness results from the release of
trapped air within the cartridge and will disappear within a few
weeks after installation.
NOTE: Use only genuine OMNIFILTER replacement cartridges
for best results. Failure to use OMNIFILTER replacement
cartridges will void your warranty.

TROUBLESHOOTING

Leaks between cap and bottom of housing:
1. Turn off water supply and depress pressure-relief button.
Remove the bottom of the housing.
2. Clean and lubricate o-ring with silicone grease. Also, clean
the groove where the o-ring seats with a clean cloth. Replace
o-ring back in groove above threads. Screw bottom of housing
back on cap securely by hand.
DO NOT OVER-TIGHTEN.
3. Turn on water supply. If leaks persist, or if there are other
leaks on the system, turn off water supply. Call OMNIFILTER
Customer Service at 800.279.9404.
Leaks on inlet/outlet connections:
1. Turn off water supply and turn on faucet to release pressure in
pipes. Remove tubing from fitting (see step 5 under Installation)
and make sure end of tubing is cut squarely and free of burrs.
Reinsert tubing into quick-connect fittings, making sure to
push securely until tubing hits a hard stop.
2. Turn on water supply. If leaks persist, or if there are other leaks
on system, turn off water supply. Call OMNIFILTER Customer
