DuPont™ Water Filtration would like to thank you for your recent purchase of the DuPont™ Reverse Osmosis Filtration System.

We greatly appreciate your business and the opportunity to assist you. Your satisfaction is the greatest importance to us. We hope that you will inform us if there is ever anything we can do to improve our products. Please contact us if you have any questions or if there is anything we can do to assist you with your new product.

Reverse Osmosis, also known as hyper filtration, is the most common treatment technology used by premium bottled water companies. It is effective in substantially reducing a very wide array of contaminants. The pores in a reverse osmosis membrane are approximately 0.025 micron in size (bacteria are 0.2 to 1 micron & viruses are 0.025 to 0.4 microns).

How Reverse Osmosis works –

Your new Reverse Osmosis (RO) system is composed of a 3-stage system manifold, a 3000 series pre-filter, the reverse osmosis membrane, a storage tank, a 3000 series post-filter and a faucet to deliver the filtered water to your countertop. First the water goes to the pre-filter, which is a replaceable cartridge that reduces chlorine, odor, sand, silt, dirt, and other sediments to improve the taste of your water. Next, the water flows to the Reverse Osmosis cartridge, which is a tightly wound membrane that reduces the total dissolved solids and organic matter. The water goes from the membrane into the storage tank. A diaphragm inside the tank keeps the water pressurized to about 30 psi when the tank is full. This is what provides the fast flow to the faucet. When the tank is empty, it should be pressurized to 5 – 7 psi. As water is drawn to the faucet, it flows from the storage tank through the final filter. This is a replaceable cartridge that reduces any remaining tastes and odors to provide cleaner great tasting drinking water to the faucet.

Your system also has an automatic shutoff valve to conserve water. When the storage tank is full and the faucet is not open, pressure closes the shutoff valve to stop flow of water with contaminants to the drain. After enough drinking water is drawn from the faucet, the pressure in the Reverse Osmosis system drops and the shutoff valve opens to allow the tank to be re-filled.

Reverse Osmosis uses a membrane that is semi-permeable, allowing cleaner water to pass through it, while rejecting the contaminants that are too large to pass through the tiny pores in the membrane. This quality reverse osmosis system uses a process known as cross-flow to allow the membrane to continually clean itself. As some of the fluid passes through the membrane the rest continues downstream, sweeping the rejected contaminants away from the membrane and down the drain. The process of reverse osmosis requires a driving force to push the water through the membrane - the pressure provided by your home’s water supply is sufficient: 40 to 100 psi.

What it removes –

Your Reverse Osmosis (RO) unit will reduce Chlorine, Odor, Particulates, Sediment, and improve taste, according to NSF 42 standards. It will also reduce Total Dissolved Solids (TDS), Pentavalent Arsenic, Hexavalent Chromium, Lead, Cadmium, Cysts, Nitrate Plus Nitrite, Nitrate, & Nitrite according to NSF 58 standards.

Thanks again for your purchase

CAUTION

This filter must be protected from freezing, which can cause cracking of the filter and water leakage.

CAUTION

Because of the product’s limited service life and to prevent costly repairs or possible water damage, we strongly recommend that the housing be replaced every five years. If the head of the filter has been in use for longer than this period, it should be replaced immediately. Date the top of any new head to indicate the next recommended replacement date.

Plan Your Installation

It is recommended to read through the entire manual before beginning your installation.

Follow all steps exactly. Reading this manual will also help you get all the benefits from your system.

Your Reverse Osmosis Drinking Water System can be installed under a sink or in a

remote location. Typical remote sites are a basement or laundry room or utility room. Review the location options below and determine where you are going to install your system.

Under The Sink Location

The Reverse Osmosis Filter Assembly and storage tank are normally installed in a kitchen or bathroom sink cabinet. See Fig. 1.

A suitable drain point is needed for reject water from the Reverse Osmosis Filter.

Remote Location

You can also locate the Reverse Osmosis Filter Assembly and storage tank in a remote location away from the Reverse Osmosis Faucet. You will need a nearby water source and drain point. See Fig. 2.

Drain Connector Installation
Choose the drain outlet location. See Fig. 1 (page 3)
	NOTE: Extra care should be taken when entering drains near dishwashers or food waste disposals, as backflow
	may occur through the air gap and cause flooding.
1	Remove protective cover from back of Foam Seal					. Knock out center hole and align holes then attach to Drain Connector
	front plate		.

2Position the Drain Connector on the sink drain pipe above the drain trap. Allow room for drilling. Tighten Screws and Nuts securely.

3Use a battery powered or properly grounded drill. Using the Drain Connector port as a drill guide, drill a 7/32” hole through the wall of the drain pipe. Do NOT penetrate the opposite side of the pipe and be careful not to damage the side of the drain port fitting.

4If you wish to install your drain in a remote location refer to page 10.

STEP 3

Install RO Filter System Assembly

The Reverse Osmosis Filter System Assembly Head is mounted on Mounting Screws .

The Mounting Screws allow you to lift the RO Filter System Assembly without any hardware removal.

1Choose an easy-to-access area under the sink to mount the RO Filter System Head.

NOTE: To allow adequate space for filter changes, allow a minimum clearance of 4” - 6”below the filter to the floor. The Filter System Assembly must be mounted in a vertical position.

NOTE: Mount the Filter System Head to a solid cabinet wall or wall. If a solid surface is not available, use hollow-wall anchor bolts or toggle bolts (not included) to secure to the wall.

2Using the Built-in Bracket on the back of the RO System Head , mark the holes for the Mounting Screws on the wall surface.

3Using a 1/8" drill bit, drill two pilot holes for the Mounting Screws. Insert Mounting Screws into the wall with a Phillips screwdriver, leaving approximately 3/8" of each Mounting Screw exposed.

Install Water Storage Tank

Before you begin, check pressure in tank. Adjust to between 5 and 7 psi.

The Tank Ball Valve fitting on the Water Storage Tank may need to be tightened 3-4 turns to get a good seal. Do not over tighten.

TO INSTALL WATER STORAGE TANK:

1 Apply 2-3 wraps of Plumber’s Tape H to the threads on the nipple at the top of the Water Storage Tank E

2Locate the Tank Connector D . Hand tighten onto the Water Storage Tank E nipple 3-4 turns, being careful not to cross thread or over tighten.

3Do not connect the tube at this time. This will occur later in the assembly.

4Place the Water Storage Tank E next to the Reverse Osmosis Filter System Assembly. The Water Storage Tank E can be placed upright or on its side. Use provided mount stand.

STEP 5

Install RO Faucet

SELECT LOCATION OF REVERSE OSMOSIS FAUCET MOUNTING HOLE

You will need to select the location of the Reverse Osmosis Faucet P . You have three options to choose from:

Use an existing sink top hole. This may be blank. This is for the spray hose or soap dispenser (Must be between 1-3/8” and 1-5/8” in diameter)

Drill a new hole in the sink

Drill a new hole in the countertop next to the sink

1Determine where you are going to install your RO Faucet Body P .

2Check to ensure the RO Faucet Body P will mount flat against the mounting surface.

3Visually review the routing of the tubes from the RO System Head A to the RO Faucet Body P . Check to ensure there is adequate tube routing space between the RO Faucet Body P and RO System Head A .

4If drilling is needed, drill a 1-3/8" diameter hole in the mounting surface.

IMPORTANT: Drilling holes into countertops and sinks should only be performed by a quali ed installer who is certi ed for drilling such materials. Drilling of surfaces made of stone or solid surface materials such as granite, marble, Corian™ or other plastic resin products or sinks made of porcelain and stainless steel may cause permanent, irreparable damage to the sink or countertop surface.

STEP 9

Install RO System and Drain In Remote Location

INSTALL A REMOTE DRAIN POINT AND AIR GAP (Remote Location)

You can also run the drain tubing to an existing drain in the house. A floor drain, laundry tub, standpipe, sump, etc. are suitable drain points. This type of drain is preferred over the drain connector. Check your local codes. Longer lengths of tubing (see parts list in manual) may be needed.

Always be sure to provide an air gap between the end of the hose and the drain point. This will prevent water from backing up into the system. Air gaps are required code in most areas.

TO INSTALL A REMOTE DRAIN POINT, COMPLETE THE FOLLOWING STEPS:

1Remove the 1/4" Red Plastic Tubing R from the RO Faucet Body P by pulling gently.

2Determine if this length is long enough to reach the drain point. If it is, then insert Restrictor I in end of tubing and then insert this end of tubing into drain port on RO Membrane Filter B2 .

3If not, replace the 1/4" Red Plastic Tubing R with an adequate length of tubing to reach the drain point. Then insert Restrictor I in end of tubing and then insert this end of tubing into drain port on RO Membrane Filter B2 . Refer to Step 6 in manual on how to disconnect and connect tubing.

4Run the tubing to the drain point and secure at the end with a bracket (purchased locally). Provide a 1-1/2” air gap between the end of the tube and the drain.

5Remove 3/8" White Plastic Tubing T from RO Faucet Body P and discard.

6Faucet will not have 1/4” or 3/8” tubing attached to the airgap barbs in the RO Faucet Body P for remote installation.

	STEP	10	10
	Sanitize, Test and Purge System		G
	SANITIZE THE SYSTEM
	Sanitizing is recommended immediately after installation of the RO Filter System Assembly. It’s also recommended after servicing inner
	parts. It is important that the person installing or servicing the system have clean hands while handling inner parts of the system.		A
	Complete the following steps to sanitize the system.
			D
	1 Make sure the water supply to the RO Filter System Assembly is off.		U

2Open the Reverse Osmosis Faucet. If the Water Storage Tank is not already empty, allow the water to completely empty.

3Find the eyedropper G included in package and common household bleach (5.25%).

4	Disconnect the 3/8” White Plastic Tubing		from the Water Storage Tank		by unscrewing the nut from the Tank Connector		fitting.
		U		E		D

5Add 3 ml. of bleach into the open end of Water Storage Tank E 3/8”White Plastic Tubing S . Handle bleach according to manufacturer’s instructions.

	6	Re-connect Water Storage Tank and 3/8”White Plastic Tubing		to Tank Connector		fitting.
			S		D
							E
	7	Sanitizing the RO Filter System Assembly will be completed during the pressure test and purging following steps below.

NOTE: The bleach must be completely removed from the system before drinking the RO water. See purging instructions below.

PRESSURE TEST THE SYSTEM

IMPORTANT: Complete the sanitizing procedures above before pressure testing.

1Open the cold water supply valve to the RO Filter System Assembly. See page 3, Fig. 1

2Open the kitchen faucet. This will purge air from the plumbing system. Close kitchen faucet when water runs smooth.

3Ensure RO Faucet is closed.

4Pressure will start to build in the RO Filter System Assembly in about 2 hours. Carefully inspect all fittings and connections while the RO Filter System Assembly builds pressure. Check for leaks and fix if any are found by ensuring all tubing is cut square and fully inserted. Also ensure tubing doesn’t have a scratch, dent, or notch at the end. If so, cut 1” off squarely and re-insert. If problems exist, refer to the troubleshooting chart or call the toll free number.

NOTE: When the RO Filter System Assembly is first pressurized, water may “discharge” from the faucet air gap hole until air is passed from the

RO Filter System Assembly.

PURGING THE SYSTEM

1Open the Reverse Osmosis Faucet and let water flow through the system for a 24 hour period. Water will flow heavily until tank becomes empty, and then it will be a slow drip for the balance of 24 hours.

NOTE: The flow rate will be very slow during the purge.

2

3

Close the Reverse Osmosis faucet after the 24 hour purge is complete. Your Reverse Osmosis system is ready for use when the purge is complete.

Review the following operating features before using your Reverse Osmosis System:

You will not have filtered water immediately. It will take 1-3 hours to completely fill the storage tank to create liberal flow from the faucet. The flow rate from the Reverse Osmosis system will be less than your kitchen faucet. Water will run to the drain while the Reverse Osmosis is filtering water, even when you are not using it. You may hear a water going to the drain – this is normal. Water going to the drain will automatically stop when the storage tank is at capacity.

THAN K YOU FOR YOUR BUSIN ESS!
