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 ow of the ltered 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 before they
need to be replaced. Filter cartridge life varies depending on usage,
and/or water conditions. Changes in taste, color, and ow of the
water being ltered indicate that the cartridge should be replaced.
NOTE: Read all instructions before replacing lter cartridge.
A. Turn off cold water supply and open the drinking water
faucet to release pressure from system.
B. Unscrew and remove bottom of lter housing. Locate and
remove large o-ring, wipe clean of lubricant, and
set aside. Repeat for second housing.
C. Discard used lter cartridges. Using a non-abrasive sponge
or cloth, scrub the bottom of lter 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 lter 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 lter cartridge in bottom of appropriate lter
housing.
J. Screw bottom of housings onto caps 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 nes. 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, ltered 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.
