PRECAUTIONS
WARNING: Do not use with water that is microbiologically unsafe or of unknown source/quality without
adequate disinfection before or after the system.
CAUTION: Filter housing must be protected against freezing temperatures, frost, snow, sleet, and ice.
Exposure to these elements can produce cracks and product failures.
CAUTION: This product has a limited service life. We recommend that a record be kept regarding the
date of install and any other performed maintenance. Because of the product’s limited service life and
to prevent costly repairs or possible water damage, we strongly recommend that the head of the filter
be replaced every ten years.
CAUTION: Turn off water supply to head and remove cartridges if it must be left unattended for an
extended period of time.
•For cold water use only. Do not use on hot water line.
• After prolonged periods of non-use (such as during a vacation) it is recommended that the system
be flushed thoroughly. Let water run for 5–6 minutes before using.
• The lters recommended for use with this system carry a limited service life. Changes in taste, odor,
color, and/or flow of the water being filtered indicate that the cartridge should be replaced.
• Make certain that installation complies with all state and local laws and regulations.
• The contaminants or other substances removed or reduced are not necessarily in your water.

INSTALLATION
• Consult your local plumbing codes and install accordingly.
• If your sink does not have a water sprayer hole, go to step 1, if your sink does have a dedicated faucet hole,
go to step 3.
NOTE: The filter life indicator faucet should be positioned with function, convenience and appearance in
mind. An adequate at area is required to allow faucet base to rest securely. Most sinks have pre-drilled
1-3⁄8˝ or 1-1⁄2˝ diameter holes that may be used for faucet installation. If these pre-drilled holes cannot
be used or are in an inconvenient location, it will be necessary to drill a hole in the sink to accommodate
the faucet.
NOTE: DO NOT DRILL THROUGH AN ALL-PORCELAIN OR CAST IRON SINK. If installing on an
all-porcelain or cast iron sink, the faucet must be mounted in a pre-drilled sprayer hole or through
the countertop next to the sink. If the countertop must be drilled, make certain that the area below the
drilling location is free of wiring and pipes. Also, make sure that there is sufcient room to make the
proper connections to the bottom of the faucet mount.
NOTE: Consult with a plumber or the countertop manufacturer for assistance with drilling through
countertops more than 1˝ thick or if it is made of tile, marble, granite, or similar material.
CAUTION: The use of safety glasses and
respirator for this procedure is recommended.
In order to prevent parts and materials from
falling down the drain, line the sink with
newspaper or a towel.
Place masking tape over the area to be drilled
to prevent scratches if drill bit slips.
Using a pencil, mark the drill hole. Drill a hole
for faucet (most sinks have 1-3⁄8˝ or 1-1⁄2˝
diameter holes).
Drill completely through the sink
or countertop.

Guide the black rubber gasket onto the threaded
faucet stem. Lower faucet stem through hole in
sink. Make sure the faucet sits flat on top of the
sink or countertop surface.
From underneath the sink, guide the metal lock
washer onto stem, then screw the plastic faucet
stem nut all the way up the faucet stem and
tighten with fingers to secure faucet to sink.
Remove spare battery and put inside the slot just
below the Culligan logo (positive side facing out).
Turn off cold water shut-off valve then turn on
the kitchen faucet and allow all water to drain
from line.
Disconnect the cold water line from the
cold water shut-off valve.
NOTE: If rigid plumbing pipe (metal or plastic)
is used, you may need to shorten the pipe using
a hacksaw or pipe cutter to accommodate the
water supply adapter.

allow space for filter changes. The filter system
must be mounted in a vertical position.
NOTE: Filter head should be mounted on a stud
or firm surface.
Hand-tighten the water supply adapter to the
cold water shut-off valve as shown.

Using the built-in bracket on the back of the
system head, mark with a pencil the holes for
the mounting screws on the wall surface.
Using a 1/8˝ drill bit, drill two pilot holes
for the mounting screws. Insert mounting
screws into the wall with a screwdriver,
leaving approximately 3/8˝ of each mounting
screw exposed.
Hang the system head on the eyes of the bracket
and replace the system head cap.

NOTE: Routine maintenance and cartridge
replacement will not require that you disconnect
the tubing from the system head; however, tubing
may be quickly and easily removed from the
fitting if necessary. First, turn off the water supply
to the filter. Open kitchen faucet, then press in
the grey collar around the fitting while pulling the
tubing with your other hand.
Determine the length of 1/4˝ plastic tubing
needed to connect the system head inlet to the
water supply adapter (reference image above
for inlet and outlet location). Make sure to allow
enough plastic tubing to prevent kinking in
the line.
Cut the 1/4˝ plastic tubing squarely on both ends
with a utility knife, making sure not to crimp the
plastic tubing during cutting.
Wet one end of the 1/4˝ plastic tubing with
water and push it into the water supply adapter
approximately 5/8˝ until it stops.
Wet the other end of the 1/4˝ plastic tubing with
water and push it into the system head inlet
approximately 5/8˝ until it stops.
NOTE: Do not bend or crimp 1/4˝ plastic tubing
when inserting.

TROUBLESHOOTING
LEAKS BETWEEN THE SYSTEM HEAD AND THE FILTERS:
1. Turn off the water supply to the lter and dispense water from kitchen faucet until water and
airflow stops.
2. Remove cartridge and inspect o-rings to make sure they are in place and clean.
3. Install cartridge, turn on water supply and check for leaks.
LEAKS AROUND THE FITTINGS:
1. Turn off the water supply to the lter to relieve pressure.
2. While pulling the 1/4˝ plastic tubing with one hand, press in on the grey collar around the inlet and/
or outlet tting. Check to make sure that the 1/4˝ plastic tubing is cut squarely and that it is not
scratched or crimped. If the 1/4˝ plastic tubing is unevenly cut or scratched, cut off 1/2˝ to 5/8˝ and
re-install the tubing.
3. Turn on water supply and check for leaks.
LEAKS ON THE WATER SUPPLY ADAPTER CONNECTION:
1. Turn off the water supply to the lter to relieve pressure.
