Introduction
Thank you for your purchase of a state of the art Watts®Premier®
Water Treatment system.
UV Water Treatment System:
The Watts Premier Under-Counter UV-3 Stage Water Filtration
System combines high-quality sediment filtration and Coconut Shell
Carbon Block filtration, with the added level of Ultraviolet (UV) water
treatment to provide a powerful, protective home Water Filtration
package. This system features a compact, space-saving under-
counter design, with a long reach dedicated filtered water chrome
faucet. Ultraviolet Water Filtration is achieved by using Ultraviolet
lamps. Water is routed through a chamber or housing that contains
the UV Lamp, as the water passes the UV lamp, the microbes in the
water are exposed to the UV rays. The microbes are then rendered
inactive.
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 elements,
other bad tastes and odors will be apparent in your drinking water.
This is why it is important to change your filters at the recommended
intervals as indicated in this system manual.
When replacing any of the filter elements, pay special attention to
any cleaning instructions. Should you have any further questions
please refer to our web site at www.premierH2o.com or call our
customer service department at 1-800-752-5582.

Installation
This system has been designed to fit under most kitchen sinks. Please
read the entire manual 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 during maintenance and filter changes. System must
be installed to the cold water supply only. Allow approximately
2" (5cm) clearance between the bottom of the filter housing
and the floor of the sink cabinet.
(B) – Using the mounting holes on the bracket, mark the location for
the mounting screws on the cabinet wall under the sink.
(C) – Screw the (2) screws into the wall at the marked location.
(D) – Hang the module on the screws using the mounting holes in
the bracket.

Counter Top / Porcelain & Stainless Steel Sink
NOTICE
Most sinks are pre drilled with 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 1)
Porcelain sinks are extremely hard and can crack or chip
easily. Use extreme caution when drilling. Watts accepts no
responsibility for damage resulting from the installation of
faucet. Diamond tip bit recommended.
Step 1
Determine desired location for the
RO faucet on your sink and place a
piece of masking tape over where
the hole is to be drilled. Mark the
center of the hole on the tape.
Step 2
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 3
Using a ½" diamond tip hole saw,
proceed to drill the large hole. Keep
drill speed on the slowest speed
and use lubricating oil or liquid
soap to keep the hole saw cool
during cutting.
Step 4
After drilling, remove all sharp edges
and make sure the surroundings of
the sink are cooled before mounting
the faucet.
Mount the Faucet & Connect Blue Tube to
Faucet
Refer to installation instructions found on faucet box.
Mount the faucet and connect ¼" blue tube found in the shipping
box to the faucet.

CAUTION
!
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.
Step 5
Turn off the cold water supply to the faucet by turning the angle
stop valve completely off. Open cold water on the sink faucet to
relieve pressure.
Step 6
Choosing the configuration that fits your plumbing, attach the
adapt-a-valve as illustrated in the four photos above.
*Do not forget to install the white compression washer for 3⁄8"
configuration.

It is essential that the outside diameter be free of score
marks and that burrs and sharp edges be removed
before inserting into fitting.
Fitting grips before it seals. Ensure tube is pushed into the
tube stop.
Push the tube into the fitting, to the tube stop. The collet
(gripper) has stainless steel teeth which hold the tube
firmly in position while the O-ring provides a permanent
leak proof seal.
Pull on the tube to check that it is secure. It is a good
practice to test the system prior to leaving site and /or
before use.
To disconnect, ensure the system is depressurized before
removing the tube. Push in the collect squarely against
face of fitting. With the collet held in this position, the tube
can be removed. The fitting can then be reused.
How to use the Quick Connect Fittings
To make a connection, the tube is simply pushed into the fitting. The
unique locking system holds the tube firmly in place without deforming
it or restricting flow. Use the steps below in reference to any quick
connect tube connections.

Green Tube Connection
Step 7
Locate the ¼" green tube in the box.
Insert one open end of the green ¼"
tube to the open ¼" quick connect
elbow fitting above the “FIVE MICRON
SEDIMENT FILTER” label making
sure the tube is pushed in all the way
passed the O-ring to the tube stop.
Step 8
Insert the other open end of the green ¼" tube into the open ¼"
quick connect fitting on the plastic adapt-a-valve making sure the
tube is pushed in all the way passed the O-ring to the tube stop.
Connect Blue Tube
Step 9
Locate the ¼" blue tube attached to the faucet. Insert the open end
of the blue ¼" tube into the open ¼" quick connect elbow fitting
above the “CARBON BLOCK PRE-FILTER” label making sure the
tube is pushed in all the way passed the O-ring to the tube stop.
Start Up Instructions
To prevent the possibility of electrical shock, clean up any water
on cabinet floor and dry all water from outside of unit.
Step 10
Turn on the incoming cold water at
the angle stop valve and the Adapt-
a-Valve. Check the system for leaks
and tighten any fittings as necessary.
(Check frequently over the next
24 hours to ensure no leaks are
present).
Step 11
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 when finished.
Check for leaks. If you have any leaks, shut off the water supply to
your system, tighten any fittings / housings and restart unit.
Step 12
Plug the (24 volt) transformer power cord connector into the UV
module wire harness connector and plug the transformer into an
electrical outlet. The white UV end cap will light up when in service
(Plugged in).

Important guidelines
Do not unplug UV unit from power supply. Turning system off & 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.
Replacement filters for this and many other filtration systems can be
purchased directly from Watts Premier. Ordering options include mail
order, telephone ordering, and online filter replacement. Addition-
ally, Premier sells filtration and reverse osmosis systems suitable for
almost any individual or commercial application.

DATE FILTRE À SÉDIMENTS (6MOIS) FILTRE À BLOC DE CHARBON (6MOIS)
Introduction
Merci pour votre achat d’un système de traitement d’eau de pointe
Watts Premier.
Système de traitement d’eau par ultraviolets:
Le système de filtration d’eau par ultraviolets en 3étapes à montage
sous le comptoir Watts Premier allie une filtration des sédiments
et une filtration à bloc de charbon de coque de noix de coco de
haute qualité avec un degré supplémentaire de traitement de l’eau
par ultraviolets (UV) afin de fournir un ensemble de filtration d’eau
puissant et protecteur pour la maison. Ce système présente une
conception compacte et peu encombrante allant sous le comptoir,
avec un robinet chromé à longue portée dédié à l’eau filtrée. La
filtration de l’eau par ultraviolets est obtenue à l’aide de lampes à
ultraviolets. L’eau est acheminée à travers une chambre ou un boîtier
contenant une lampe UV puis, à mesure que l’eau passe devant la
lampe UV, les microbes dans l’eau sont exposés aux rayons UV. Les
microbes sont alors rendus inactifs.
Entretien du système
Le goût n’est pas forcément révélateur des substances présentes.
Il existe un grand nombre de contaminants présents dans l’eau
potable qu’il est impossible de détecter au goût. Par ailleurs, si vous
ne remplacez pas l’élément de filtration, avec le temps, des saveurs
et des odeurs désagréables commenceront à apparaître dans
votre eau potable. C’est pourquoi il est important de remplacer vos
filtres à la fréquence recommandée, celle-ci étant indiquée dans ce
manuel d’utilisation.
Veillez à suivre les instructions de nettoyage avec soin lorsque vous
remplacez les éléments filtrants. Si vous avez d’autres questions,
veuillez consulter notre site Web à l’adresse www.premierH2o.com
ou appeler notre équipe du service à la clientèle au 1800752-5582.
