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 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 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 OT32 will last about 400 gallons or six
months 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. Repeat for second housing.
C) Discard used filter cartridges. Using a non-abrasive
sponge or cloth, scrub the bottom of filter housings,
O-ring grooves, and caps with dish soap and warm water.
Rinse thoroughly. Fill bottom of each housing 1/3 full with
water. Add 2 tablespoons of household bleach and scrub
to disinfect.
D) Lubricate O-rings with silicone grease. Insert each 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 housings with bleach water onto caps
without filter cartridges 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 housings and empty
of water.
I) Insert each filter cartridge in bottom of appropriate filter
housing.
J) Screw bottom of housings onto caps and hand-tighten.
DO NOT OVERTIGHTEN. 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.

2. Clean O-ring and O-ring groove (located directly beneath
threads of housing). Lubricate O-ring with silicone grease and
replace securely into groove. Screw bottom of housing onto

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.
