The system makes a good supply of drinking water each day. How much it will make depends primarily on these things…

Feed water pressure—pounds per square inch (psi)

40–125

Feed water temperature limits—minimum/maximum degrees F.

40–100

Water quality

Maximum Total Dissolved Solids (TDS)—parts per million (ppm)

2000

Maximum water hardness @ 6.9 pH—grains per gallon (gpg)

10 For water with hardness greater than 10 grains (at 6.9 pH) the use of a softener is recommended. Failure to install a water softener will reduce the life of the Reverse Osmosis membrane. See chart for additional information on the possible need for a water softener.

Percent rejection of TDS, minimum (new membrane)**

*Chlorine removed (maximum of 2.0 ppm) by the Reverse Osmosis prefilter…regular changing of the prefilter is required. Chlorine will destroy the Reverse Osmosis membrane.

**Feed water at 50 psig and 77°F. with 750 ppm sodium chloride. Quality water production, amount of waste water and percent rejection all vary with changes in pressure, temperature and Total Dissolved Solids.

On average you should expect your Reverse Osmosis system to be able to deliver 18 gallons of product per day, as tested by Water Quality Association Standard S-300. Output according to ANSI/NSF Standard 58 is 10.9 gallons per day. Process water used per gallon of water produced is four gallons.

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 system includes an electronic faucet assembly with an integrated water testing feature. When water is taken from the faucet, a green indicator light means removal is within the specified limits and water quality is good.

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

How the Reverse Osmosis System Works

Prefilter

—Water from the cold supply pipe enters the Reverse Osmosis assembly and

is directed to the prefilter cartridge.

NOTE: Before going to the prefilter, supply water first passes through the electronics box to measure TDS.

The prefilter is a replaceable sediment cartridge with activated carbon in its composition. 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, chlorine-reduced water flows from the

prefilter to the Reverse Osmosis membrane cartridge.

Product Water Storage—

The storage area holds up to 1.9 gallons of product water. The flexible bladder keeps water pressurized for fast flow to the faucet when drinking water is needed.

Check Valve—

A check valve is built into the bottom 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 rupture of the Reverse Osmosis membrane.

Automatic Shutoff Assembly—

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

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 area. Reject water, with the dissolved solids and organic matter, leaves the housing and is discharged to the drain.

Postfilter—

After leaving the storage area, but before going to the faucet, product water goes to the postfilter. The postfilter is also the activated carbon type sediment filter. Any remaining tastes, odors, or sediments are removed from product water. Clean, high quality drinking water flows through the tubing and to the faucet.

Flow Control—

The flow control regulates flow of water through the Reverse Osmosis cartridge at the required rate to produce high quality water. The control is located in the drain tubing, at the Reverse Osmosis cap fitting. A small, cone-shaped screen fits over the front end of the flow control to help prevent plugging with drain water sediments.

The Faucet and Indicator Lights

Faucet and Electronics—

The countertop faucet dispenses filtered drinking water when opened. It has a hand-operated, spring-loaded lever to prevent waste. You can keep the faucet open by pushing upward on the lever, until it locks against the faucet spout.

To comply with plumbing codes, an air gap is built into the faucet drain water connection.

The electronic faucet provides an integrated TDS monitor. As water is taken from the faucet, the indicator lights show how the Reverse Osmosis system is operating to provide high quality drinking water.

Flashing Green Light—

The Reverse Osmosis

system is providing high quality drinking water.

NOTE: If the Reverse Osmosis system is connected to the refrigerator, this light will also flash when the icemaker or water dispenser is in use.

The green light may stop flashing when the supply of Reverse Osmosis water is nearly gone and flow from the RO faucet decreases. This is a normal condition.

Flashing Amber “FILTER” Light—

The prefilter and

postfilter cartridges need replacing. See the

Care

and Cleaning

section.

Flashing Amber “RO” Light—

The Reverse Osmosis cartridge is no longer removing at least 75% of the TDS from the supply water and needs replacing. See the

Care and Cleaning

section for Reverse

Osmosis cartridge replacement.

NOTE:

Disregard initial or short periods (a few seconds) of the flashing “RO” light. Long periods of limited or non use can cause the TDS levels to temporarily change.

If the Reverse Osmosis Filtration System Is Connected to Your Icemaker

Before you service the filter, change the filters, or purge the Filtration system, YOU MUST turn off the icemaker by raising the feeler arm. Four hours after servicing your unit, lower the feeler arm to resume icemaking.

CAUTION: The Reverse Osmosis cartridge contains a food grade preservative that should be purged from the system before first use or whenever the Reverse Osmosis cartridge is replaced. The preservative will give product water an unpleasant taste and odor.

Make sure all tubing connections are

tightened.

Make sure the red tank shutoff valve is open. Turn on the water supply valve to the Reverse Osmosis system.

In about four hours, pressure will start to build in the Reverse

Osmosis system.

At that time,

carefully check all fittings and tubing connections for any water leaks. Correct leaks if any are found.

Open the RO water faucet to drain the storage tank.

Close the RO water faucet after draining. Wait four hours until system has refilled. Then open the RO faucet to drain the storage tank.

Repeat the purging process for a total of four times.

The system is ready to make product water for your use.
