Thank you for your purchase of a
state of the art Watts Pure Water
Treatment system.
PWDWLCV2 Water Treatment System:
Watts Pure Water PWDWLCV2 water treatment system contains a
heavy duty lead, cyst and VOC filter block. This specialty formulated
block is capable of reducing lead, cryptosporidium, Giardia, Ent-
amoeba as well as harmful Volatile Organic Chemicals. It is estimated
that VOC’s are present in one-fifth of the nation’s water supplies.
These water contaminants can enter ground water from a variety of
sources including localized use of herbicides and pesticides, gasoline
or oil spills, leaking underground fuel tanks, septic system cleaners,
and chemicals used in the dry-cleaning industry.
System Maintenance
Just because you can not taste it, does not mean that it is not there.
Many contaminants in the drinking water are undetectable to the
taste. Additionally, over time if you do not replace the filter element,
other bad tastes and odors will be apparent in your drinking water.
This is why it is important to change out your filter at the recom-
mended intervals as indicated in this system manual. When replac-
ing any of the filter elements, pay special attention to any cleaning
instructions. Should you have any further questions please refer to
our website at www.watts.com or call our customer service depart-
ment at 1-800-244-1299.
Maintenance Record
This system has been designed to fit under most kitchen sinks.
Please read carefully before proceeding with installation.

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 1
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.

Standard Faucet Installation
STEP 2
Step A – Remove nut (item 11) and blue tubing (item 12) from faucet
(Leave the nut and plastic delrin sleeve (item 10) on the
blue tube).
Step B – Feed both the red and black tubing through the pre drilled
hole in the sink/counter until faucet is seated.
Step C – Under the sink - on to the threaded faucet stem in order
first slide on the rubber gasket (item 6), the slotted washer
(item 7), the white spacer with the open end UP (item 8),
the hex nut washer (item 9), and lastly secure with nut (item
11).
Step D – Make sure the plastic delrin sleeve (item 10) is on the end
of the blue tube, push the white plastic insert (item 13) into
the end of blue tubing with the delrin sleeve, insert the blue
tube (item 12) into the faucet stem and secure with nut
(item 11).
Note: DO NOT overtighten nut.

STEP 3
Drinking Water Module Mounting
Step A – Determine best location for
the Drinking Water system to
be mounted to allow for future
system maintenance. The
parts bag has 2 self tapping
screws. Using an electric drill
with a Phillips bit, screw them
into the cabinet wall 6" apart
and 16" from the bottom of the
cabinet.
Note: Do not cut any Drinking Water system tubes at this time
Start Up Instructions
Step A– Turn on the incoming cold water at the angle stop valve.
Turn the knob on the Adapt-A-Valve™ by turning coun-
terclockwise. Check the system for leaks and tighten any
fittings as necessary. (Check frequently over the next 24
hours to ensure no leaks are present).
Note: If you have connected your RO system to a refrigerator /
ice maker, make sure the ice maker is off (do not allow water to
flow to the ice maker) until flushing is complete and the tank has
been allowed to fill completely. Connection from the RO to the
ice maker system should have an in-line valve installed before
the ice maker so it can easily be closed to prevent water flowing
to the ice maker during start up and periodic maintenance. Your
RO tank must be allowed to fill up fully in order for the ice maker
system to work properly.
Step B – Turn faucet handle to the open position to start the flow
of water through the unit. Run 7 gallons of water through
the unit in order to flush out the normal black carbon fines
(it will “sputter” until the air is purged out) from the unit.
Initially, the water may appear cloudy which is due to tiny
air bubbles and it will clear up shortly. Close the faucet.
Step C – Check for leaks. If you have any leaks, shut off the water
supply to your system, repair and restart unit.
Adapt-A-Valve™ Installation
Verify contents prior to installation:
( 1 ) - Plastic Adapt-a-Valve™ & Black Collet
( 1 ) - Brass Adapter no washer
( 1 ) - Brass Adapter with black washer
( 1 ) - White rubber washer
Water supply line to the system must be from the cold water
supply line only. Hot water will severely damage your system.
WARNING: Do not use Teflon tape with the Adapt-A-Valve™.
For 3⁄8" Configuration
For 1⁄2" Configuration
Step A - Turn off the cold water supply to the faucet by turning the
angle stop valve completely off.
Step B - Open cold water sink faucet to relieve pressure.
Step C - Choosing the configuration that fits your plumbing, at-
tach the Adapt-A-Valve™ as illustrated in the four photos
above.
