Installation
This system has been designed to fit under most kitchen sinks.
Please read carefully before proceeding with installation.
Step 1: Mounting System Under Sink
A. Locate a space under the sink that allows the unit to be
mounted close to the cold water supply and allows for
easy access when changing filters.
Allow 2" (5cm) clearance between the bottom of the filter
housing and the floor of the sink cabinet for filter changes.
B. Using the mounting hole on the bracket, mark the location
for the mounting screws on a wall under the sink.
C. Screw the (2) screws into the wall at the marked location.
D. The UC-2 bracket is designed to be mounted without
removing the (2) screws. Hang the UC-2 module on the
screws using the mounting holes in the bracket.
Step 2: Installation of Faucet
Special Note: Porcelain sink surface material is extremely hard
and can crack or chip quite easily. Use extreme caution when
drilling. Watts accepts no responsibility for consequential damage resulting from the installation of faucet to the sink or
counter top.
Colored faucets can be ordered through Watts toll-free customer service department by calling (1-888-774-7405). in the
Continental United States or 623–505-1512 outside the
United States, or online at www.wattsind.com
A. Remove faucet kit from plastic bag and locate each of the
following parts (as shown in Figure A).
Note: Remove plastic tubing from faucet body before inserting
long reach spout into faucet body.
Note: If using existing hole (sprayer or soap dispenser) go to
Step G.
B. Determine the desired location for the faucet on your
sink surface.
C. Place a piece of masking tape or duct tape on location
where the hole is to be drilled. Mark the center of the hole
on the tape.
Note: Stainless steel sinks only go Step F.
D. Using the variable speed drill on the slowest speed, drill a
1
/8" (3mm) pilot hole at the center of the desired location.
Use lubricating oil or liquid soap to keep the drill bit cool
while drilling. Note: If drill bit gets hot it may cause the
porcelain to crack or chip. Pilot hole must be drilled
through both porcelain and metal casing of the sink before
proceeding to the next step.
E. Enlarge pilot hole to
1
/4" (6.4mm). Keep drill speed on the
slowest speed and use lubricating oil or liquid soap to keep
drill bit cool.
F. Enlarge the
1
/
4" hole to
7
/
16" (11.13mm). Keep drill speed on
the slowest speed and use lubricating oil or liquid soap to
keep drill bit cool.
G. Pass the Escutcheon plate and black rubber washer over
threaded mounting tube at the base of the faucet body.
H. From top of sink pass the threaded mounting tube through
the hole drilled in the sink. Align the faucet body.
I. From under the sink, slide the locating washer and the lock-
washer over the threaded tube part of the faucet. Screw on
retaining nut. Tighten with wrench.
J. Connect the loose end of the
1
/4" blue plastic tubing from
the filtration unit to the threaded mounting tube of the
faucet as shown Figure B.

Step 3: Installing Easy Tap Adapter
Cold Water Supply Only
Easy tap adapter is to be installed on 1/4" male or female
pipe thread connections before angle stop valve or onto the
sink faucet.
Note: If your plumbing does not allow for connection of the
easy tap adapter, contact your local plumbing or hardware
store for modifications.
A. Turn off the main supply water to the house if installing
before the angle stop valve as shown in figure C1, or shut
off the water supply at the angle stop valve if installing on
to the faucet as shown in figure C2.
Note: Thread connection of the angle stop valve and housing
plumbing may be the opposite of that shown in figure C1.
B. Teflon
®
tape the 1/8" male pipe thread of the easy tap valve.
Screw the valve into easy tap valve body.
C. Disconnect the fitting where the easy tap valve is to be
installed. Secure both sides of the fittings with wrenches
where the easy tap valve is to be installed.
D. Insert the easy tap gasket into the female portion of easy
tap. No plumbing dope or Teflon
®
tape should be required
on the male pipe threads.
E. Thread easy tap valve on to the
1
/
2" male pipe threads and
tighten securely with wrench.
F. Thread angle stop valve or plumbing connection to easy tap
adapter and tighten securely.
G. Connect green tubing from unit to the easy tap valve (as
shown in figure C1 or C2).
H. Make sure easy tap valve is closed by turning handle
clockwise.
I. Turn on water supply and open easy tap valve by turning
handle counter clockwise and check for leaks.
Step 4: Start Up
A. Lift black faucet handle up on faucet to start flow of water
through unit. Run 7 gallons of water through unit. Close
faucet. Note: You may hear some noise as air is being
purged from the unit. The first few ounces of water from the
unit may be dark in color due to carbon fines from the filter.
B. Your water is now ready for drinking.

Note: There will be water in the unit filter housing. Lift the
faucet handle to relieve the water pressure.
B. Remove filter housing from lid by unscrewing to the left, as
shown in Figure D.
C. Remove used filter cartridges and discard. Discard the
P-CB-1 gaskets.
Note: Do not discard the filter housing O-ring.
D. Clean inside of filter housing with warm soapy water. Rinse
the filter housing with warm clean water to remove soap.
E. Lubricate filter housing O-ring with water-soluble lubricant
(i.e. K-Y Jelly
®
or Silicone lubricant)
Note: Do not use Petroleum base lubricant (i.e. Vaseline
®
).
F. Seat O-ring in groove in filter housing.
G. Insert new filter cartridges into filter housing.
H. With the filter bowl in a upright position, screw filter housing
back onto lid as shown in Figure D.
