Filter Cartridge Replacement - Pentair OMNIFILTER USM2 Instrucciones De Instalación

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 12 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 cartridge.

FILTER CARTRIDGE REPLACEMENT

A) (1) Turn off water supply to filter and place a tray or towel
under the system to catch any water that spills during
removal of the filter cartridge. (2) Depress red pressure-relief
button, or open cold water faucet, then (3) unscrew and
remove bottom of filter housing (See Figure A).
NOTE: If turning off water supply to filter will also turn off
water supply to the rest of the home, be sure to fill a bucket
of water first to allow you to clean housing after it has
been removed.

B) (1) Locate and remove large O-ring. Wipe it clean of
lubricant, and set aside. (2) Discard used filter cartridge.
Rinse out bottom of filter housing and fill 1/3 full with water.
Add 1 tablespoon of bleach and scrub bottom of housing
with nonabrasive sponge or cloth. Rinse thoroughly. Lubricate
O-ring with clean silicone grease. Insert O-ring in groove and
press into place.
NOTE: This step is important to ensure a proper housing seal.
Make certain the O-ring is seated level in the groove.
Insert new filter cartridge in bottom of housing. Single gasket
cartridges should be inserted in the housing with the gasket
end facing the threads of the housing. Cartridges with
tapered ends need to be installed with the open tapered end
toward the threads of the housing. (See Figure B for correct
installation).

C) (1) Screw bottom of housing onto the cap and hand-tighten.
DO NOT OVER-TIGHTEN. (2) Slowly turn on the water
supply to allow filter to fill with water, then (3) press the red
pressure-relief button on top of filter to release trapped air.
Check for leaks before leaving installation.
NOTE: A drinking water cartridge may contain carbon fines
(very fine black powder). After installation, flush the cartridge
for 5 minutes to remove the fines before using the water. It is
recommended that you run the tap at least 20 seconds prior
to using water for drinking or cooking purposes.
We recommend using the GAC1 replacement cartridge for
the USM2 drinking water filter.
