Installing PURE WATER PRODUCTS' Q Series Undersink Reverse Osmosis Unit

The unit is designed to be the world's most easily installed reverse osmosis system.. The instructions are somewhat detailed because there are a number of parts. Don't hesitate to call for advice if you get stuck: 940-382.3814.

Our standard 3- or 4-stage Q Series RO (Reverse Osmosis) unit is designed to facilitate installation and to make it easy to talk about if you call for information. Here is essentially what you are going to do. You don't have to follow this order, but it probably is easier if you do.

1. Install the ledge faucet. You'll need to use an existing hole in your sink or drill a new one. You'll need a hole 7/16" or larger. Be sure to check for braces and other obstructions before you drill. Install the faucet placing parts in the order shown in the diagram. Tighten securely. Don't connect the attached blue tube to the unit for the present. (The attached tubing is not shown in the diagram.)

2. Install the inlet saddle valve on the COLD water faucet pipe under your sink . The kit included is for copper pipe. If you have other than copper, please call for instructions. If you have copper, follow the instructions in the kit. ATTACH THE SADDLE AROUND THE PIPE, BUT DO NOT PIERCE PIPE AT THIS TIME. The purpose of this part is to provide inlet water for the reverse osmosis unit

The illustration shows the correct positioning of the valve around a 3/8" undersink pipe. Before installing on the pipe, turn the red handle full counterclockwise. If the pipe is larger than the 3/8" pipe shown (most are 3/8"), reverse the metal wedge so that the larger side faces the pipe. Tighten the set screw (shown in the installer's left hand) until the valve is firmly secured to the pipe, but don't overdo it. You can flatten the pipe and cause a leak if you get it too tight. A small crescent wrench or open end wrench is only tool you'll need.

After the installation of the entire RO unit is complete, start the unit by piercing the pipe to allow water to enter. You pierce the pipe by turning the red handle as far as it will go clockwise, then you open the valve to allow water in by turning counterclockwise. Leave the valve open (full counterclockwise) all the way for operation of the unit.

3. Install the drain saddle on the undersink drainpipe. The easy way is to drill a small hole (1/4" or slightly less) in the plastic or metal drainpipe, then position the saddle over the hole and tighten securely. Install on horizontal or vertical pipe. (The horizontal pipe assures noise-free performance.) Install above the J or P trap in the drainpipe. (The purpose of this part is to provide a drain for the RO unit. Water will flow from the unit's drain line, through the hole you drill, and into the drainpipe.)

Drain Saddle

4. After the faucet, inlet and drain are in place, position the unit and the storage tank conveniently under the sink. (The two don't have to be together--they can be on opposite sides of the sink compartment.) The unit can be hung on the wall using the holes in back of the bracket, or it can be stood on the floor in a secure place. Position so that tubes will not be crimped.

5. Connect the unit to your plumbing using the John Guest fittings. (See Illustration Below.) Be sure the end of the tubing is cut square, then push in until you feel the tube hit bottom. Should you need to remove the tube, push in on the collet with your fingernail and pull the tube out simultaneously.

Connecting Tubing with John Guest Fittings

Here are the connections you will make:

A. Attach the clear line from inlet valve to the fitting in the port in back of the Inlet Vessel, or Prefilter. The Prefilter is on your left as you look the unit in the face.

B. Attach the blue line from the faucet to the fitting in front of the Post Filter. The post filter is the vessel on your right as you face the unit.

C. After screwing the John Guest elbow fitting into the drain saddle, attach the black drain line that comes out of the bottom of the membrane (the center vessel) to the drain saddle.

D. Install the tank valve enclosed in the box with the tank to the top of the tank. The fitting is has been taped with teflon taped. Just screw it on (not too tight). When the valve is in place, attach the orange tube coming out of the tee in the back of the unit to the valve in the top of the tank.

Startup

When all connections are made, open the unit's ledge faucet (pull up the handle and it will lock open), and close the valve on top of the storage tank. (Handle perpendicular to tubing is off.)

Next, pierce the cold water line with the inlet valve, as described above and turn on the inlet valve. Gradually open the valve and let water flow into the unit. If there are no leaks, open the inlet valve all the way and let the unit run.

After some initial noises, the unit will run smoothly until water begins to drip from the faucet. This will take several minutes, perhaps half an hour. Allow water to drip from the faucet for about an hour to thoroughly rinse the unit and purge it of air.

After an hour, close the faucet, open the valve on top of the tank, and let the unit fill the tank. Allow the unit to run for at least five or six hours in this fashion, then open the faucet and let the tank empty into the sink. When the water returns to a fast drip or small stream, close the faucet and begin to collect water again. Operation of the unit is fully automatic from this point. It will shut itself off when the tank is full. If it seems to run too long for the first few days, don't be concerned. It takes awhile for the unit to purge itself of air and get down to normal operation.

You can begin to use the water at any time from this point. (You won't have a lot of water until the unit has time to fill the tank, but it can be used at any time.)

After a few more hours of operation, drain about a quart of water from the tank, then capture a glassful and test it with the TDS meter. Follow instructions provided with the meter. Your reading for the RO water should be about 1/10 that of the tap water. E.g., if the tap water reading is 500, the RO water should be no higher than 50. If it isn't good enough, wait a couple of days and repeat the test. (It takes time for all impurities to rinse from the unit, and the meter can see impurities that your eye can't.)

It usually takes a new reverse osmosis unit at least a week to "mellow out" and produce really great water, so be patient with it. Also, trapped air will sometimes make water appear cloudy for several days. Don't worry. It's just air bubbles, and the problem will correct itself soon You can also expect some weird noises for the first few days that result from trapped air. That too will go away.

Maintenance

No maintenance should be needed for a year. When the unit is a year old, we'll send you a postcard reminder that it’s time to change the filter cartridges. We'll provide full cartridge change and annual maintenance instructions when you order the cartridges.

Don’t hesitate to use the water. Reverse Osmosis thrives on work. Don’t hesitate to use it to cook spaghetti, and especially, give it to your pets and plants. They’ll love it.

If you have ANY problems, please call right away. We want the unit to work perfectly for you, so let us know if it doesn’t perform to your satisfaction. (Most of our business comes from referrals from satisfied customers, so we do our best to keep everything running well.)
