A. O. Smith has designed, engineered, and built this ltration system to last. It
features Claryum®ltration that reduces harmful contaminants – those you can
see, smell and taste, and those you can’t – with no chemical additives or wasted
water. Whatever your water need – from hydration to cooking, early
morning coffee, smoothies, or soup, you will now have ltered water.
Keep this owner’s manual to reference installation, troubleshooting
and lter replacement information.

Tools recommended for installation:
• Variable speed drill w/ 7/32" bit
• Adjustable wrench
• Measuring tape
• Bucket
• Phillips head screwdriver
• Hammer
Faucet may be mounted on sink using an
existing hole for a sprayer nozzle or soap
dispenser, or by drilling a hole no more
than 1/2" in diameter. Be sure location
of faucet allows spout to extend slightly
past the edge of sink.

Check for leaks and proper installation: Turn on
cold water. Place towel under lter unit and check
for leaks. Allow water to run 10 minutes to ush.
Note: Never use oils to lubricate the O-rings;
O-rings come pre-lubricated.
Unit installation: Select a space under sink for lter
unit that is at least 3" from bottom of your cabinet
and allows for easy access to cold water supply and
lter replacements. Use mounting holes located on
back of unit to pencil in the wall screw placements.
Note: Center to center hole distance is 2.55".
Use a 7/32" drill bit to drill holes for plastic anchors.
Carefully tap anchors into the drilled hole with a
hammer. Mount unit to the wall with screws. Pull
protective plastic strip from the battery compartment.
The red LED should ash and beep ve (5) times to
indicate that battery is installed correctly.
Faucet connection: Connect outlet hose
to base of faucet by sliding chrome nut
onto tube followed by the white collar.
Place white insert into the end
of tube. Press tube against the faucet
base and slide the nut and collar up to
the threads. Use wrench to ensure seal
is sufciently tight.
INSTALLATION GUIDE
Connect supply lines: Insert tubing from
tee tting into the inlet side and insert
tubing from faucet into the outlet side.
Use diagram to mark tubing depth to
ensure they are completely inserted.
It is VERY IMPORTANT to insert tubing
completely so leaking does not occur.
Faucet Installation: Install as shown.
Tighten faucet nut (I) to secure
faucet to sink.
TIPS
Insert tubing all the way (.95") to prevent leaking.
Wet end of tubing for an easy install into inlets and outlets.
Cut excess tubing to prevent crimping, kinks, loops or folds.

A
Attach one white poly tube to the brass tee, and slide compression
nut onto the tubing (with threads of nut facing end of the tube).
Next, slide the plastic sleeve onto the tube. Place brass insert into
the opening of tube. Push tip of the tube into opening of the brass
tee. While holding the tube in place inside the brass tee, tighten
compression nut to compress plastic sleeve and create a seal.

To clean your lter unit, wipe down
the exterior with a damp cloth.
Once lters are at 95% capacity (about
every 6 months), the battery alarm will
sound and ash red when water is
owing and will continue for 15 seconds
once water is turned off. Change the
battery every time you replace your lters.
The battery is included with the lter
replacement cartridges.
Safeguards
• Use only cold water with lter.
• If you experience a hose connection
leak, disconnect and re-seat the hose.
Do not use with water that is microbiologically
unsafe or of unknown water quality without
adequate disinfection before or after the
system. Systems certied for cyst reduction
may be used on disinfected waters that may
contain lterable cysts.
