Introduction

Thank you for your purchase of a Watts water treatment
system.

PWDWHCUC1 water filtration provides clean, clear, great tasting
water with a higher flow and gal-lon rating than other similar
systems.

Your new water treatment system contains a heavy duty

System Maintenance

Just because you cannot 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 recom­mended intervals as indicated in this system manual. When replacing
the filter element, pay special attention to any cleaning instructions.
Should you have any further questions please refer to our website at
www.watts.com/purewater or call our customer service department
at 1-800-244-1299.

With proper installation and maintenance, this system will provide
you with high quality water for years to come. If you have any ques­tions or concerns, please contact our Customer Service department
at 1-800-244-1299 or refer to our on-line troubleshooting at

STEP 1

Blue Tube Connection- Angle Stop Valve

NOTICE

Do not use with hot water supply. Hot water will severely
damage your system, will not filter properly, and can result in
leaks and property damage. Water supply line to the system
must be from the cold water supply only.

NOTICE

Step A - Turn off the cold water

Step B - Open cold water sink

Step C - Place a small container

Step D - Locate the blue 3/8” tube

Step E - Insert the assembled blue tube into the open fitting of the

supply to the faucet by

STEP 2

Blue Tube Connection- Faucet Hose

Step A - Locate the threaded 3/8” male stem

adapter fitting in the parts bag. Thread the stem
adapter on to the supply hose attached to the
faucet and tighten with an adjust-able wrench.

Step B - Locate the 3/8”x3/8” Quick Connect
union in the parts bag. Push the union on to the
3/8” stem adapter fitting attached to the faucet hose
until fully seated.

Step C - Connect the open end of the 3/8” blue
tube to the open end of the 3/8”x3/8” Quick con­nect union fitting by pushing the tube into the
adapter until fully seated.

STEP 3

System Module Mounting

Step A – Determine best location for
the filtration system to be mounted

and spliced into the 3/8” blue tubing.
Using the mounting holes on the
bracket, mark the location for the
mounting screws on the cabinet wall
under the sink (Make sure to leave
enough room to remove the filter during

filter changes, approximately 2” below filter). In the parts bag, locate
the two self tapping screws. Using an electric drill with a Phillips bit,
screw them into the cabinet at the marked location. Hang the system
on the screws using the mounting holes in the bracket

the tubing firmly into the quick
connect fitting. Connect the
3/8” blue tube coming from the faucet supply hose into
the right side of the filtration system (OUT), by pushing the
tubing firmly into the quick connect fitting.

System Start Up

Step A– Slowly turn on water. Check for signs of leaks or damage at all

locations including water supply connection, at cold water faucet hose
connection, at quick connect fittings, at angle stop valve connection and at
filter module and cartridges. Inspect connections, lines and filter module/
cartridges at least every six months thereafter for signs of leaks or damage.
Turn water off immediately and replace if leaking, weeping, cracked, damaged
or corroded.

Step B – Run 5 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 when finished.

NOTICE

Check frequently over the next 24 hours to ensure no leaks are present
