IMPORTANT SAFETY INFORMATION. READ ALL INSTRUCTIONS BEFORE USING.

■ Check with your state and local public works department for plumbing and sanitation codes. You must follow these guidelines as you install the Reverse Osmosis system. Using a qualified installer is recommended.

■ If house water pressure is over the maximum (125 pounds per square inch), install a pressure reducing valve in the water supply line to the Reverse Osmosis system.

■

Be sure the water supply conforms with the Specification Guidelines. If the water supply conditions are unknown, contact your municipal water company or your local health department for a list of contaminants in your area and a list of laboratories certified by your state to analyze drinking water.

WARNING: Before using the Reverse Osmosis

system for the first time, the system must be purged. The Reverse Osmosis cartridge contains a food grade preservative that must be purged from the system. The preservative will give product water an unpleasant taste and odor.

■ This product reduces fluoride in drinking water. Please consult your dentist if you have questions.

WARNING: Do not use with water that is

microbiologically unsafe or of unknown quality

without adequate disinfection before the system. Systems certified for cyst reduction may be used on disinfected water that may contain filterable cysts.

This system has been tested for the treatment of water containing pentavalent arsenic (also known as As(V), As(+5) or arsenate) at concentrations of

0.050 mg/L or less. This system reduces pentavalent arsenic, but may not remove other forms of arsenic. This system is to be used on water supplies containing a detectable free chlorine residual or on water supplies that have been demonstrated to contain only pentavalent arsenic. Treatment with chloramine (combined chlorine) is not sufficient to ensure complete conversion of trivalent arsenic to pentavalent arsenic. Please see the Arsenic Facts section of the Performance Data Sheet for further information.

This Reverse Osmosis system contains a replaceable treatment membrane cartridge critical for effective reduction of Total Dissolved Solids. The water should be tested periodically to verify that the system is performing satisfactorily. See the About the Water Test K i t section.This system is acceptable for treatment of influent concentrations of no more than 27 mg/L nitrate and 3 mg/L nitrite in combination measured as N and is certified for nitrate/nitrite reduction only for water supplies with a pressure of 280kPa (40 psig) or greater.

SAVE THESE INSTRUCTIONS

READ AND FOLLOW THIS SAFETY INFORMATION CAREFULLY.

■ Install or store where it will not be exposed to temperatures below freezing or exposed to any type of weather. Water freezing in the system will damage it. Do not attempt to treat water over 100°F.

■ Do not install on HOT WATER. The temperature of the water supply to the Reverse Osmosis system must be between the minimum of 40°F and the maximum of 100°F. See the Specification Guidelines.

■ Extended non-use of the Reverse Osmosis system. If the system has not been used for one week or more, open the RO water faucet and allow the system to drain. Close the RO water faucet and allow the system to regenerate the water supply.

■ Recommended installation is under the sink. However, the unit can be installed in a remote location, up to 20 feet away from the sink. Additional installation materials may be required. If Reverse Osmosis system is connected to a refrigerator icemaker, a special icemaker connection kit is required (RVKIT).

Things to Check Before Beginning Installation

FEED WATER

The water supply to the undercounter Reverse Osmosis system must have the qualities listed in the specifications (see the Specifications Guidelines section). Municipal water supplies most often will have these qualities. Well water may need conditioning— have the water tested by a water analysis laboratory and get their recommendations for treatment.

CAUTION: For water with a hardness

greater than 10 grains (at 6.9 pH), the use of a softener is recommended. Failure to install a softener will reduce the life of the Reverse Osmosis membrane. See the Specifications Guidelines section for additional information on the possible need for a softener.

DRAIN POINT

A suitable drain point and air gap (check your local codes) are needed for reject water from

the Reverse Osmosis membrane cartridge.

BASEMENT INSTALLATION

If installing in a basement, leave enough tubing in place during installation to be able to move unit to floor for ease at servicing and making filter/membrane changes. Additional tubing and fittings required.

RO FAUCET

The RO product water faucet installs on the sink or on the countertop next to the sink. Often, it is installed in an existing sink spray attachment hole or a hole may be drilled. Space is required underneath for tubing to and from the faucet, and for securing the faucet in place. All faucet connections and installation procedures are done on or above the sink or countertop. Refer to illustration above.

Description of the Reverse Osmosis System

Prefilter—Water from the cold supply pipe is

directed to the prefilter cartridge, which is inside the sump.

The prefilter is a replaceable sediment cartridge containing activated carbon. The cartridge removes sand, silt, dirt, other sediments and up to 2.0 ppm of chlorine from the feed water. The prefilter reduces chlorine in the feed water because CHLORINE DESTROYS THE REVERSE OSMOSIS MEMBRANE. Filtered, clean, chlorinereduced water flows from the prefilter to the Reverse Osmosis cartridge.

Storage Tank—The storage area holds up to 3 gallons of product water. A diaphragm inside the tank keeps water pressurized for fast flow to the faucet when drinking water is needed.

Check Valve—A check valve is built into one end of the Reverse Osmosis housing. The check valve prevents a backward flow of product water from the storage area. A backward flow could cause the Reverse Osmosis membrane to rupture.

Automatic Shutoff Valve—To conserve water, the drinking water system has an automatic shutoff. When the storage tank has filled to capacity and the drinking water faucet is closed, pressure closes the shutoff. Water flow to the Reverse Osmosis housing is shut off until drinking water is used again, and pressure drops in the Reverse Osmosis system.

About the reverse osmosis system.

What the Reverse Osmosis System Does

Reverse Osmosis removes Total Dissolved Solids (TDS) and organic matter from water by diffusing it

through a special membrane. The membrane separates minerals and impurities from the water and they

are flushed to the drain. High quality product water goes directly to the drinking water faucet or to the storage tank. The system makes a good supply of drinking water each day; see Specification Guidelines. How much it makes depends on the feed water supply pressure, temperature and quality.

The carbon prefilter and postfilter are replaceable cartridges. The prefilter removes chlorine while also filtering sediments. The postfilter removes any other undesirable tastes and odors before you use the water.

Reverse Osmosis Cartridge—The cartridge, inside the Reverse Osmosis housing, includes a tightly wound, special membrane. Water is forced through the cartridge where the membrane removes the dissolved solids and organic matter. High quality product water exits the Reverse Osmosis housing and goes to the storage tank. Reject water, with the dissolved solids and organic matter, leaves the housing and is discharged to the drain through tubing.

Postfilter—After leaving the storage area, but before going to the system faucet, product water goes to the postfilter which is inside the sump. The postfilter is also a replaceable sediment cartridge that contains activated carbon. Any remaining tastes, odors or sediments are removed from product water by the postfilter. Clean, high quality drinking water flows through the tubing and to the system faucet.

System Monitor—

A timer is provided in the faucet base to remind you when it is time to replace your prefilter and postfilter. Replace the filters when the blue light begins to flash in order to protect the RO membrane and keep the system functioning properly. Be sure to remove and replace the battery at the same time to reset the timer.

Flow Control—The flow control regulates the flow of water through the Reverse Osmosis cartridge at the required rate to produce high quality water. The control is located in the Reverse Osmosis housing drain port. A small, coneshaped screen fits over the front end of the flow control to prevent clogging due to sediments in drain water. The flow control and screen should be replaced each time the Reverse Osmosis membrane cartridge is changed.
