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.
