Introduction

Thank you for your purchase of a state-of-the-art Watts water treatment system. Your new system is equipped with a unique swivel valve in the head assembly. This allows for a simple and sanitary twist off filter change that does not require you to turn off the water source to the filtration system. This 3-Stage system is equipped with a Sediment Prefilter, a high-quality Carbon Block Filter, and the Ultra Filtration Membrane. The sediment filter reduces sand, silt, sediment and rust particles that may be in your water. The second stage is a high-quality carbon block filter for chlorine, taste and odor reduction. The third stage is our state-of-the-art UF Hollow Fiber Technology membrane for the removal of most colloids and impurities as small as 0.1-micron nominal. Ultrafiltration is a membrane filtration process that uses standard home water pressure to push water through its semi-permeable membrane. Suspended particles and materials of high molecular weight are unable to pass through the nominal 0.01-micron UF membrane, allowing only fresh clean water and dissolved minerals to pass through. Historically this separation process has been used in large municipal water treatment plants and hospitals; however, through advances in technology, it is now available to you as a powerful under-sink water filtration plant in your home. Ultrafiltration is capable of running at low water pressures, does not require a separate water holding tank, does not alter the pH of your water and does not require electricity. Due to this, the PWDWUFKC3 provides a continuous supply of premium quality drinking water directly to your tap.

NOTICE: Filter & Membrane life may vary based upon local water conditions and/or use patterns.

System Maintenance

Just because you cannot taste it, does not mean that it is not there. Contaminants such as lead, chromium and arsenic (to name a few) 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 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 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 online troubleshooting at www.watts.com.

If any of the items are missing please contact us prior to installing.

Tools Recommended for Installation

• Small knife
• Variable Speed Drill
• 1⁄2″ & 5⁄8″ Open End Wrenches
• 1⁄2″ Hole Punch (for stainless steel sinks)
• 1⁄2″ Diamond Tip Drill Bit (for porcelain sinks)
• 1⁄8″ Drill Bit
• 1⁄4″ Drill Bit
• 7⁄16″ Drill Bit
• Phillips Screw Driver

Drill a Hole for the Faucet in a Porcelain Sink

Note: Most sinks are predrilled with 1½” or 1¼” diameter holes that you can use for your Drinking Water faucet. (If you are already using it for a sprayer or soap dispenser, see Step A).

NOTICE: 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 the 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 the 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 1⁄2″ hole saw, proceed to drill the large hole. Keep the drill speed on the slowest 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.

OR

Punch a Hole for the Faucet in a Stainless Steel Sink

NOTICE

• If mounting the faucet to a Stainless Steel Sink you will need a 1⁄2″ Hole Punch.
• The faucet opening should be centered between the backsplash 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.

The faucet can now be installed.

How to use the Quick-Connect fittings on the UF Module

To make a connection, the tube is simply pushed into the fitting. Place a piece of tape 1⁄2″ from end of tube to indicate how far the tube should be inserted. The unique patented Quick-Connect locking system holds the tube firmly in place without deforming it or restricting flow.

1. Cut the tube square. It is essential that the outside diameter be free of score marks and that burrs and sharp edges be removed before inserting into the fitting.
2. Fitting grips before it seals. Ensure tube is pushed into the tube stop.
3. 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 leakproof seal.
4. 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.
5. To disconnect, ensure the system is depressurized before removing the tube. Push in the collet squarely against the face of the fitting. With the collet held in this position, the tube can be removed. The fitting can then be reused.

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

NOTICE

• The water supply line to the system must be from the cold water supply line only. Hot water will severely damage your system.
• Do not use Tefl on 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 the cold water sink faucet to relieve the pressure
Step C: Choosing the configuration that fits your plumbing, attach the Adapt-A-Valve™ as illustrated in the four photos above.

Green Tube Connection

Step A: Locate the green tube attached to the Filter Module. Insert the open end of the green 1⁄4″ tube into the open 1⁄4″ Quick-Connect fitting on the Adapt-A-Valve™ making sure the tube is pushed in all the way to the tube stop.
Step B: Connect the green tube from the Filter module to the Adapt-A-Valve™ that is connected to the angle stop valve. Leave enough tube so it is not kinked and cut the tube to the desired length.

UF Drinking System Module Mounting

Step A:  Determine best location for the UF Filter Module 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.

NOTICE: Do not cut any UF system tubes at this time.

System Start-Up

Step A: Turn on water supply at the angle stop and open the Adapt- A-Valve™. Turn the faucet handles to the open position to start the flow of water through the unit. Run 3 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.
Step B: Check for leaks. If you have any leaks, shut off the water supply to your system, tighten any fittings/housings and restart unit.

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