attached to the unit. Clean the pipe threads with paint thinner or
solvent (NOT gasoline) and dry them with a clean rag; remove all
chips; polish and deburr. Use only teflon tape (without adhesive
backing) on the pipe threads attached to this unit.
6. Apply teflon tape three turns around the threads of the pipe
coming from the water meter. Using the "IN" port (see Figure 4),
hand screw the filter onto the water pipe until it is tight.
Removing the tank will make this easier. DO NOT OVERTIGHTEN.
7. Wrap three turns of teflon tape around each end of the 2" nipple
and screw one end into the "OUT" port on the filter (see Figure
4). Screw the union onto the other end of the nipple.

8. Wrap the remaining pipe thread with teflon tape and screw the
other side of the union onto it until tight.
9. Assemble the union and tighten the large nut securely. Make sure
that the pipe ends align and that the union is clean for a water-
tight fit (no tape or compound on the union-half threads).
All Installations:
10.Install the filter cartridge in the Cartridge Tank.
11.To avoid flooding and water damage, make sure that the
O-Ring between the housing and the tank is in good condition
and properly seated in its groove when reassembling the unit.
12.The filter is now ready to test. Turn the filter top (using the blue
wrench supplied with the filter) clockwise to "OFF". Slowly open
the main water supply valve and check for leaks. Turn the filter
top (again using the wrench) from "OFF" to "FILTER". If any fit-
tings or joints leak, tighten slowly until the dripping stops.
13.Open the faucet and flush the filter for at least 3 minutes after
installation to remove the "carbon fines" – minute black particles
flushed out of the new filter. Flush the unit for at least 10 sec-
onds every time you use water for drinking or cooking, especially
if the water tap is not used daily.
WHEN TO CHANGE THE CARTRIDGE
The cartridge's life depends on the water volume used and the sub-
stances in the water. Normally the cartridge should be changed at
intervals of ninety days or less. Replace it sooner if the water pres-
sure at the faucet begins to drop noticeably or if you notice changes
in the taste, color, or flow of the filtered water.
Certain types of harmless bacteria will attack cellulose material.
Cartridges containing cellulose may seem to disintegrate, produce a
"sewer" or "rotten egg" odor, or form a black precipitate due to bac-
teria. If this happens, consult OMNIFILTER Customer Service for advice.
PROCEDURE FOR CARTRIDGE CHANGE
1. Place a pan under the unit to catch any spilled water.
2. Turn the filter top (using the blue wrench supplied with the car-
tridge) clockwise about 45° to "OFF".
3. Fit the wrench onto the
ribs of the tank and turn
it to the left to loosen the
tank (see Figure 5).
4. Support the tank as you
unscrew it. Pour out the
water from the tank and
remove and discard the
old cartridge. Wipe the
inside of the tank clean
and dry with a soft cloth.

5. Insert a new cartridge into the tank, making sure that it seats
over the center post on the tank bottom.
6. Lubricate the tank O-ring with a good grade of silicone grease or
food-grade vegetable oil and check it for damage. If cut, abrad-
ed, or stretched, replace it with a new one.
7. Screw the filter tank back onto the filter housing. Tighten the
tank snugly with the filter wrench. DO NOT OVER TIGHTEN.
8. Turn the top of the filter to "FILTER" with the filter wrench.
NOTICE: If the tank O-ring leaks after you have tightened the tank
with the wrench, DO NOT tighten it anymore. Instead, loosen it and
make sure that the cartridge is seated over the center tube in the
head assembly (not pushing against it). After centering the cartridge,
re-tighten the tank and again check for leaks.
9. Open a faucet for about 3 minutes to allow any accumulation of
air, fines, etc., to blow through.
NOTICE: Use only genuine OMNIFILTER replacement cartridges for
best results. Failure to use OMNIFILTER replacement cartridges will
void your warranty.
NOTICE: The filter tank has a limited service life. Replace it every 5
years. Be sure to date the replacement for future reference and mark
the new replacement date.
