First-time Use – Install Filters
1. Verify that the O-ring is properly seated inside the groove on top of the filter housing. A
light amount of food-grade, silicon jelly may be used to help the O-ring seal better if
desired but is not required.
2. The filter cartridges are preserved in shrink wrap.
Note the direction sign on the sticker prior to
removing the wrap.
3. When placing the filter cartridge into the housing,
make sure it is centered and the protruding knob at
the bottom of the housing fits securely in the filter’s
central hole.
4. Screw the housing, with filters attached, onto the cap,
which should also have a center knob which should be inserted into the center hole of
the filter cartridge. Turn the housing in a clockwise direction by hand, then use the
housing wrench to tighten it another 1/4 – 1/2 of a turn and ensure it is snug. Do not
over-tighten. This can cause leaks and make it difficult to unscrew the housing when
replacing filters.
5. Slowly turn on water main to fill the housing. After a few minutes, the sound of water
entering the system will stop. Check for leaks to verify the system is operating properly.

Open the COLD-water faucet and run water for about 10 minutes to expel any carbon
fines. Let the unit sit for several minutes, then repeat if necessary.
6. Turn off the faucet, and your system is now ready for use.
NOTICE:
The water will have a blackish color for the initial flush. This is caused by residual carbon dust
and is to be expected. Continue to run water until the color runs clear and all air has been
purged. It is not unusual for the water to appear "cloudy" for a day or so following installation.
This cloudiness is actually tiny air bubbles being purged from the filters. This is normal and will
cease after a few days of operation.
NOTICE:
After prolonged periods of nonuse (such as a vacation), it is recommended that the system be
flushed thoroughly for at least 10 minutes prior to use.
Filter Change Instructions
Step 1- Remove Old Cartridges
1.1 Turn off the water supply to the system. Open a nearby faucet to release the
remaining pressure and drain the water.
1.2Unscrew the housings using the filter wrench included (AWR3) with your system, or
a commercially available “strap” type wrench.
1.3Locate and remove the large O-ring using a small, clean flat head screwdriver. Avoid
removing any of the lubricant, and set it aside in a clean, safe place.
1.4Remove and discard the old filter cartridges.
Step 2- Clean the Housings
2.1 Scrub the housings and caps with a mixture of warm water and about 2 tablespoons
of household bleach using a sponge or soft rag. For your safety, wear rubber gloves.
Rinse all parts very thoroughly!
2.2 Lubricate the O-ring with clean silicone grease if needed. DO NOT USE PETROLEUM
JELLY. Insert the O-ring into the filter groove and press into place. Verify the O-ring is
seated correctly.

CAUTION:
This step ensures the proper filter seal. Make sure the O-rings (ORB) are level when
seated in the groove. If the O-ring appears damaged, stretched, or crimped, it should be
replaced immediately.
Step 3- Install the New Cartridge
3.1 Remove the new filter packaging and insert the filter cartridges into the housings,
making sure they slip over the bottom standpipe.
3.2 Align the bottom of the housing with the cap and hand tighten, then use the filter
wrench (AWR3) until snug.Do not over-tighten.
3.3 Close any open valves. Turn on the water supply slowly to allow the system to fill
with water.Inspect carefully for leaks.If a leak is found, remove the housing and inspect
the O-ring to ensure that it is seated properly, and then retighten.
Step 4- Flush the System
4.1 Flush the system by turning on a cold-water faucet. Allow the water to run until the
air and carbon has been purged. Water may initiallyappear cloudy as the filters and
system remove trapped air. New activated carbon filter cartridges may contain loose
carbon and air bubbles after installation.
Maintenance Instructions
Your water system requires periodical care and cleaning throughout its lifetime. It is
recommended that the cartridges be replaced every 12-24 months, depending on the number of
contaminants present in the water supply. If the system has been functioning properly and the
pressure is slowing, this could indicate that it is time to change the filter cartridges.
Replacement cartridges and parts can be ordered online at www.123filter.com or
by calling 678-261-7611.
