Introduction

Thank you for your purchase of a Watts Pure Water under coun-

ter ﬁltration system with UV. With proper installation and mainte-

nance, this system will provide you with high-quality water for years

to come. All of Watts Pure Water water enhancement products are

rigorously tested by independent laboratories for safety and reliability.

STEP 1

Mounting System Under Sink

Step 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 during maintenance and filter changes. Allow

2" (50mm) clearance between the bottom of the filter

housing and the floor of the sink cabinet.

Step B Using the mounting hole on the bracket, mark the loca-

tion for the mounting screws on the cabinet wall under the

sink.

Step C Screw the (2) screws into the wall at the marked locations.

Step D The UV modules bracket is designed to be mounted

without removing the screws. Hang the UV module on the

screws using the mounting holes in the bracket.

Drill a Hole for the Faucet in a Porcelain Sink

Note: Most sinks are predrilled with 1½" or 1¼" diameter hole

that you can use for your RO faucet. (If you are already using it

for a sprayer or soap dispenser, see Step 2).

Caution: Porcelain sinks are extremely hard and can crack or

chip easily.

Use extreme caution when drilling. Watts accepts no responsi-

bility for damage resulting from the installation of faucet.

Step A – Determine desired location for

the RO faucet on your sink

and place a piece of masking

tape on over where the hole is

to be drilled. Mark the center

of the hole on the tape.

Step B – Using a variable speed drill

set on the slowest speed, drill

a 1⁄8" pilot hole through both

porcelain and metal casing

of sink at the marked center

of the desired location. Use

lubricating oil or liquid soap to

keep the drill bit cool. (If drill

bit gets hot, it may cause the

porcelain to crack or chip).

Step C – Using a 1¼" hole saw, pro-

ceed to drill the large hole.

Keep drill speed on the slow-

est speed and use lubricating

oil or liquid soap to keep the

hole saw cool during cutting.

Step D – Make sure the surroundings

of the sink are cooled before

mounting the faucet to the

sink after drilling and remove

all sharp edges.

STEP 2

Punch a Hole for the Faucet in a Stainless

Steel Sink

Note: If mounting faucet to a Stainless

Steel Sink, you will need a 1¼" Hole

Punch. The faucet opening should be

centered between the back splash

and the edge of the sink, ideally on the

same side as the vertical drain pipe.

Step A – Drill a ¼" pilot hole. Use a 1⁄2"

Hole Punch and an adjustable

wrench to punch the hole in the

sink. Change to the 1¼" Hole

Punch to enlarge the hole

The faucet can now be installed.

Figure A: List of Parts and Assembly in Exploded View

Figure B: Complete Assembly

Gather and identify the faucet pieces.

Step A - Place the escutcheon chrome plate and the black rubber

washer on the faucet shank . (Parts found in faucet parts

bag) .

Step B - Insert the faucet shank through the hole in sink and let it

rest on the sink top .

Step C - From the underside of the sink, slide on the location wash-

er, star washer and Lock nut onto the stem bolt . Check for

orientation the tighten lock nut securely .

Step D - Locate the Blue tube from the Filters . Measure the tube

from the unit over to the faucet and cut it to the desired

length . Remove a the compression nut, plastic sleeve and

tube insert from the parts bag . To assemble, place the

compression nut on the tube ﬁrst, then the sleeve (small

tapered end of the sleeve must point to the end of tube)

and then insert the tube insert all the way into the end of

the tube .

Step E - Push the assembled blue tube into the faucet until it stops

. Slide compression nut and plastic sleeve down until you

can thread nut onto the faucet . Use a wrench to securely

tighten the compression nut while continuing to push the

tube into the faucet

Step 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 and the first few glasses of water through the unit may be

dark in color due to carbon fines.

Step B Check for leaks. If you have any leaks, shut off water sup-

ply to system, repair and restart unit.

Step C Connect plastic electrical connector from UV unit to the

plastic electrical connector from AC adapter.

Step D Plug adapter into GFCI electrical outlet. You will see a

pale blue light from the view port on the UV housing

body. The light indicates that the UV lamp is on and

working.

Please follow these guidelines:

Do not unplug UV unit from power supply. Turning system off

and on will shorten the life of the UV lamp. UV should be on

continuously for maximum effectiveness.

The system requires a warm-up period for proper operation.

Wait 20 minutes after plugging in the system before using water.

Water not drawn from unit for a period of time may have a

taste or odor and will be warm. To avoid this, allow water to run

through the system for one minute before using.
