Fit the wrench onto the ribs of the tank and turn it slowly to
the left to release the pressure and loosen the tank.
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.
Insert a new cartridge into the tank, making sure that it seats
over the center post on the tank bottom.
Lubricate the tank O-ring with a good grade of silicone
grease or food-grade vegetable oil and check it for damage.
If cut, abraded, or stretched, replace it with a new one.
Screw the filter tank back onto the filter housing.
Hand-tighten the tank. DO NOT OVER TIGHTEN.
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.
Open a faucet for about 10 minutes to allow any
accumulation of air, fines, etc., to flush out.
NOTICE:
Use only genuine OMNIFILTER replacement cartridges
for best results. Failure to use OMNIFILTER replacement
cartridges will void your warranty.
TO ByPASS ThE FIlTER
When watering lawns or doing other projects that don’t require
filtered water, the U25 Series D Complete Household Water Filter
System can be bypassed.
Turn the filter top (using the blue wrench supplied with the
cartridge) clockwise about 45° to “BY-PASS”. Refer to Figure
5 under the “Procedure for Cartridge Change.” section.
To continue use of the Filter System, turn the filter top
(using the blue wrench supplied with the cartridge) counter-
clockwise about 45° to “FILTER”.
