PREFACEThe purpose of this booklet is to provide some basic information about Reverse Osmosis (RO)

and its potential benefits to homeowners, institutions, small businesses, industry and evenmunicipal water suppliers. It seeks to answer some of the most common questions and is notintended to be an exhaustive treatment of the subject. It is also an installation and servicemanual.

The question of quality drinking water is becoming increasingly important to all of us today.Every day we learn of more sources of water pollution and their potential impact on our healthand standard of living. Just because water appears to be clear to the naked eye does notnecessarily mean that it is free of contamination. Pure water is tasteless, odorless and colorless,but some of the invisible contaminants are harmful in measurements as small as parts per millionand some even in parts per billion. That may seem to be an insignificant amount of material, butin the environment of our body cells, it can be an overwhelming amount.

Although, a good reverse osmosis system can be depended on to reduce or remove mostwaterborne contaminants with certain limitations, the most important reason people obtain theseunits is to have better tasting water. The MT3 RO will enable you to serve glasses of crystalclear, delicious drinking water, better tasting coffee, tea, iced tea, juices, soups, clear and harderice cubes, etc. Have you ever wondered why a cola purchased from some national restaurantchains is consistently good, no matter where you buy it? The answer is in the pure water theyadd to the concentrated syrup. You too can have good, high quality water in your home at theturn of the tap.

Some Suggested Uses ofRO Water

•••• All drinking water•••• All water for cooking

INTRODUCTION TO REVERSE OSMOSISHow Reverse Osmosis Works

The process known as osmosis occurs inNature when solutions with two different con-centrations are separated by a semi-permeablemembrane. Osmotic pressure drives water withlower dissolved solids through the membraneto dilute the more concentrated solution.

If instead enough hydraulic pressure is ap-plied to the concentrated solution to counteractthe osmotic pressure, we accomplish what isknown as Reverse Osmosis. This processforces water molecules through the membrane

while the dissolved solids including salts andsugars are left behind to be flushed to the drain.

Different feedwater may require differenttypes of RO membranes. Materials of construc-tion include cellulose tri-acetate (CTA) and thin-film composite (TFC).

A properly designed RO system is probablythe most economical and efficient method avail-able for the purification of tap water.

The Superior Design of the MT3 ROThe MT3 Reverse Osmosis drinking water

system produces a high quality water by theremoval of as much as 95% or more of thedissolved solids and virtually all of the chlorine,tastes, odors and organics found in the watersupply.

The MT3 offers a number of features andbenefits that make it an exceptional product:

The standard unit includes a 2.1-gallon stor-age tank. An optional larger tank is available.

The system drain shuts down when the stor-age tank is about 2/3 full of RO water. Besidessaving water, the pre-filter is not required to trapsediment from excess waste water thereby pro-longing its life.

FACTORS WHICH AFFECT THE LIFETIME AND PERFORMANCEOF THE MT3 RO MEMBRANE

1. Type of membrane: Cellulose tri-acetate or thin-filmcomposite.

Cellulose Tri-Acetate(CTA)•••• Up to 1,000 ppm TDS with net water pressure of

50 psi•••• Chlorine tolerant•••• Some bacteria resistance•••• 4.0 to 8.0 pH•••• Pressure Range of 30 to 100 psi•••• Water Temperature of 40° to 85°F.(4-29°C)•••• Hardness less than 10gpg.•••• A chlorinated supply will increase membrane lifeThin-Film Composite (TFC)•••• Up to 2,000 ppm TDS with net water pressure of

50 psi•••• Not chlorine tolerant•••• Bacteria resistant•••• 2.0 to 11.0 pH•••• Pressure Range of 30 to 100 psi•••• Water Temperature of 40° to 100°F.(4-38°C)•••• Chemically stable•••• Hardness less than 10gpg.

2. Square feet of membrane: The square feet of mem-brane and the production of RO water are in directproportion.

3. Water Pressure: The higher the net pressure across themembrane, the greater the quantity and higher the qual-ity of RO water.

4. Total Dissolved Solids: The higher the TDS, the lowerthe production. Each 100 ppm above 500 representsabout one pound reduced pressure on the membrane.Thus 1500 ppm reduces the effective pressure by 10pounds.

5. Water Temperature: Colder water results in lowerproduction. Temperatures above manufacturer’s speci-fications are to be avoided because of problems with themembrane support structures and accelerated compac-tion rates. Connect to cold water supply only! (See Fig.3)

6. Surface Coating or Fouling: A neglected pre-filter canallow sediment to accumulate on the cartridge surfaceand impair the necessary flow of water through the filter,thus reducing membrane life. Also, salts can precipitateon the membrane, plugging the pores and channels. Awater softener or other types of pre-treatment installedbefore the RO System significantly reduces this load andextends membrane life. (See Fig. 6)

WARNING: Install only on a potablewater supply.

Step 2: Remove old membrane from thehousing.

Depending on the membrane installed in yoursystem, you will see either a short pipe protrud-ing from the end of the membrane (see Fig. 2)or you may see only a threaded hole in thecenter. Also, note how far in the membraneactually is for reference when inserting the newone. If you see a short pipe, grab onto it with apair of pliers and pull the membrane out of thehousing. If you see threads, get a standard “carriage bolt (of sufficient length to hold onto)and screw it into the membrane far enough toget a solid hold. Pull the membrane out. Youmay feel some resistance as the membranecomes unseated from the housing. Throw outthe old membrane.

Step 3: Wash your hands & the surfaces ofthe tools used to extract the oldmembrane before going onto Step 4.

Anything you can do to minimize bacterialcontamination of the system will help maintaintrouble-free performance.

Step 4: Wash and sterilize the membranehousing.

Empty any water left in the housing andwash it. Then sterilize it by filling the housingwith water to which a capful of hydrogen per-oxide has been added. Wait ten minutes thenempty. Do not rinse the membrane housing.

Step 5: Insert the new membrane into thehousing.

Open the sealed bag the RO membranecomes in with the side to be inserted up. Graspthe membrane by the bag surrounding it andhold it up to the mouth of the membrane hous-ing. Slide the membrane out of the bag and intothe housing. Using the pliers or the “ bolt usedto extract the old membrane, push the mem-

brane in until it seats in the membrane housingsecurely. Gently rock the membrane back andforth while pushing if necessary to seat themembrane properly. NOTE: It is of utmostimportance the membrane seats securely,otherwise the sealed space between rejectwater and product water is seriously compro-mised, resulting in little difference in TDS countbetween raw water and water coming from thefaucet.

Step 6: Screw the membrane housing capback into place and tighten securely.

Step 7: Re-insert red tubing into the elbowfitting on the Membrane Housingcap.

If you are performing a cartridge filter-change along with your membrane changeyou should complete the filter change be-fore turning the water back on.

If you are not doing a filter change or havecompleted it, you can now turn the water backon.

See Step 1, on page 18. Open both theSupply Saddle Valve and the Storage TankBall Valve.

Check for leaks around the membrane hous-ing cap and the elbow, then you are ready toflush the whole system.

Step 8: Discard the water already in the Stor-age Tank, by opening the RO faucetand letting it run until the water slowsto a trickle.

Then shutoff the faucet, wait 2 hours andrepeat Step 8 again. This repeated stepflushes all remnants of the disenfectant, usedto clean the membrane housing, from the stor-age tank and the system.

If the graph indicates a potential forscaling, softening the water is thesimplest pre-treatment. It is also pos-sible to lower the pH to avoid scaling,using either acid-feed or weak-acidresin treatment. Another pre-treat-ment method makes use of a poly-phosphate feeder. If the iron exceeds0.1 ppm or manganese exceeds 0.05ppm, pre-treatment for these materialswill also be required. For low levels (upto 5 ppm), either softening or polyphos-phate feeding may be used. Higherlevels may require more specializedtreatment.

designed to remove chlorine. A TFC mem-brane will not tolerate chlorine (see page 4)and will fail without a carbon pre-filter to protectit.

Step 5: Wash & sterilize filter sumps. Dumpout any water in the sumps and washthem with soap and water.

Place a capful of hydrogen peroxide intoeach empty sump and then fill them with water.Set them aside for at least ten minutes to givethem time to be sterilized.

Step 6: Wash your hands thoroughly beforeproceding to step 7.

Step 7: Empty water from filter sumps andinstall new filters.

Do not rinse the filter sumps. Remove plasticprotective wrapping from the new filters andplace each filter into its respective housing.The carbon filter will fit in only one way.

Step 8: Note the condition of O-rings andlubricate.

Remove the “O” rings from the filter sumps.Wipe them clean and apply silicone grease.

NOTE: Do not use petroleum jelly since thiswill dry out the O-rings and make them brittle.

Step 9: Reassemble filter housing.Note which sump contains the carbon post-

filter and install it on the lefthand filter (facingunit). Re-install the other sump on therighthand filter. Tighten sumps snugly ontocaps.

Step 10:Open valve on supply line and checkfor leaks.

If there are no leaks, set RO unit back intoits originally installed position.

Step 11:Flush RO system.Turn on the ROfaucet and run water until storagetank is empty.

This flushing is necessary to remove carbonfines from the carbon post-filter that are maybe present due to the manufacturing process.The water may look somewhat dark - perhapseven black. Do not be alarmed. Continue flush-ing until tank is empty. Allow several hours forthe storage tank to re-fill. Your RO system isnow back in service.

CHANGING THE RO MEMBRANEThere are a number of factors that affect the life

expectancy of an RO membrane. See page 5 formore information.

It is a good idea to have your RO water testedat installation time so you know what a good TDS(Total Dissolved Solids) count should be. If youstart noticing a difference in the taste of your ROwater, it may mean that only your filter cartridgesneed to be replaced. However, if your ice cubes arenoticeably more cloudy or if you have your watertested and the TDS is significantly higher than itwas or begins to rise noticeably over a short periodof time, the membrane probably needs to be re-placed. You’ll need to have both a raw water sampleand a product water sample for this test, since thisis the only way to determine what is a significantincrease.

Changing the membrane is not particularly dif-ficult and should be done at the same time you

change your cartridge filters. The following stepsassume this to be the case and that steps 1, 2a & 2bon page 18 have been completed. (CAUTION: Failure to perform these STEPS prior to pro-ceeding will result in spraying water on youselfand your work area.) Remember, old cartridgefilters will only shorten the life expectancy of yournew RO membrane.

Step 1: Unscrew the RO membrane housingcap.

Disconnect the red line from the elbow onthe cap of the RO Membrane Housing (SEEFigure 6 for location). Using a large wrench,a pair of channel locks, or some other similartool, unscrew the cap from the membranehousing.

Question: If the water leaving the municipalwater treatment plant is of goodquality, can I be sure of getting agood glass of water in my home?

Answer: Not necessarily, the water can pickup various contaminants on its way to yourfaucet.

Believe it or not, some cities like New Yorkstill have some old, wooden water mains.These and other leaking water mains can pickup unwanted substances such as bacteria,Giardia and Cryptosporidium. Water supplyauthorities are aware there are thousands ofsubmerged connections and cross-connectionsbetween our water and sources of contamina-tion occurring nationally, on a daily basis.Plumbing items installed in violation of buildingcode by inexperienced or short-cut-mindedpeople cause many of these problems. This isa frequent source of bacteria and other pollut-ants in municipal water systems. Clay-asbes-tos water mains can deteriorate, giving upasbestos to the water. Service entrance pipesleading into many older homes are often madeof lead. Additionally, lead can be leached outof the 50/50 lead solder used to connect thecopper pipes in homes built before the lawchanged a few years ago. Lead can also befound in brass plumbing fixtures. Point-of-use(at the tap) reverse osmosis is the most effec-tive method of achieving good, safe drinkingwater.Question: What is Reverse Osmosis?Answer: I can best answer this question byfirst explaining briefly what natural “Osmosis”is.

This is nature’s process by which moistureand nutrients are taken up through the rootsystems of plant life to its outermost leaves.Moisture drawn from the soil passes throughcell walls cell by cell in this process. It is

scientifically described as the passing of a lessdense fluid until there is an equal density of fluidon either side of the membrane, i.e., (the cellwalls). The process is repeated cell-by-cell aslife-nourishing fluid reaches the very tops of thetwigs and leaves of a plant. This same processtakes place in our own bodies and the bodies ofother animal life.

Reverse Osmosis is so named because man has,through technology, reversed nature’s process. Weforce raw tap water, which is the denser liquid,against a semi-permeable membrane by utilizing thedomestic water supply pressure or a pump. Whenforced against the one surface of the membrane thewater molecules diffuse through it molecule bymolecule forming pure water on the other side of themembrane, leaving behind up to 98% of the dis-solved solids and other impurities in the process.

Question: What happens to the impurities thatwere in the water?

Answer: They are washed down the drain.You see, unlike filters, the Reverse Osmosismembrane is self-cleaning. The source water,as it flows through the membrane module, isdivided into two streams. One stream isforced through the membrane by diffusion be-cause of the water pressure. The secondstream serves as a “rinse down” and carriesaway the rejected salts, particulate matter andother impurities to the drain. This ensuresthere is no accumulation of debris on the pres-sure side of the membrane, as a function oftime. Sediment or carbon filters, on the otherhand, lose capacity with each glass of waterdrawn. Besides losing capacity with eachglass of water drawn through them, filters onlyremove particulate matter and perhaps sometastes and odors from the water.Question: Who invented or developed Reverse

Osmosis?

Questions and Answers

PERIODIC MAINTENANCE•••• If the use of RO water is minimal, it is

recommended that the storage tank beexhausted periodically.This is necessaryto assure continued high quality water!

•••• The pre-filter should be changed at leastonce a year or when it becomes very dirtyor a restriction of flow is traced to it.

•••• The post-filter should be changed if thereis taste or odor to the product water, but atleast every twelve (12) months.

•••• The time period between RO Membranereplacements will depend on the quality ofthe supply water being treated and the typeof membrane in the system. This periodshould be between one and five years andwill be accompanied by a decrease inwater quality.

•••• The water quality (Total Dissolved Solids -TDS) should be checked frequently andalso when the taste of the water or clarity

of the ice cubes changes. You can eithertake a sample of water to your MT3 ROdealer or he can provide you with a samplebottle and mailing tube. You can purchasea TDS monitor from your MT3 RO Dealer.These monitors are available either ashandheld models or built into the RO fau-cet featuring indicator lights.

If the model number of your MT3 unit endswith the letter “C” (for example, “MT3-113C”) and the unit is installed on a chlorin-ated water supply, it is important to keep thefollowing in mind: Depending on your ROwater usage as well as the amount of chlorineresidual and organics in the supply water, theCarbon pre-filter will need to be replaced on aregular basis (usually once a year) to protectthe membrane from pre-maturely deterioratingdue to chlorine exposure.The Carbon pre-filter is sized to the system.SEE Parts List.

CHANGING THE PRE- AND POST-FILTER CARTRIDGESStep 1: Turn off the water going into the MT3

RO unit.Locate the supply saddle valve where the

RO supply tubing (Red) is connected into thesinks cold water pipe. Close the valve.

Next, close the ball valve at the Top of theMT3 Storage Tank. Relieve the pressure inthe unit by opening the RO faucet. (See Fig.6) NOTE: The water stored in the storagetank is under constant pressure. The ball valvemust be turned off. Otherwise you will exhaustall RO water from the tank when you open thefaucet before internal pressure is relieved. Youneed this water for Step 11 at the end of thisprocedure or Step 8 at the end of the Mem-brane Change Procedure.

Step 2a:Move the main unit out from undersink for better accessibility.

There will be water in the filter housings, sobe sure to place a shallow pan under the unitbefore loosening either filter housing to catchany water which may spill.

Step 2b:If you are also replacing the ROmembrane, see CHANGING THE ROMEMBRANE on page 17.

Step 3: Remove filter sumps.Unscrew eachfilter housing sump by turning clock-wise looking down at the unit.

Use a filter spanner wrench (part #4987), anoil filter wrench, a large pair of channel locksor your own hands. Remember, the housingsare screwed on tightly so they wont leak -therefore, some force may be needed toloosen them.

Step 4: Remove old filter cartridges andthrow them away.

Take a minute to visually inspect your pre-filter cartridge (right hand sump). Ordinarily, itwill be of the paper variety since its job is simplyto filter particles from the water before itreaches the RO membrane. If however youhave a special unit that uses a TFC (Thin-FilmComposite) membrane and your water supply

Answer: The spiral-wound Reverse Osmosismembrane, which is the heart of the MT3 ROsystem, was developed over many years ofresearch by scientists subsidized by the Officeof Saline Water*, a branch of the United StatesDepartment of the Interior. The Office of Sa-line Water expended many millions of dollars inthe development of Reverse Osmosis. TodayReverse Osmosis. is regarded as the most ef-fective and efficient water cleaning method.

(*Now called the Department of Water Re-search & Technology)Question: I understand that Reverse Osmosis

removes at least 95 percent of theimpurities. Does this mean that ittakes out the minerals?

Answer: Yes, it removes or reduces the ex-cess minerals along with many other impuritiesthat may be present in tap water.Question: Well, I have always had the impres-

sion that water should contain min-erals; that they are essential to one’shealth.

Answer: If that were true, the population inparts of the country served by water containinglittle Total Dissolved Solids (TDS) would be atrisk. Also, modern research by biochemists,nutritionists and medical doctors clearly indi-cates that we get enough natural minerals fromour food to satisfy our body’s needs. We don’tneed the excessive inorganic minerals that arefound in tap water.Question: Does MT3 RO water taste flat?Answer: No, most people believe that it is themineral content of water that makes it tastegood. However, it is the oxygen content ofwater that gives it good taste. This is whyspring water bubbling to the surface tastes sogood. Oxygen permeates the MT3 membraneeven faster than water. This is why MT3 wateris highly oxygenated and has that delicious“mountain spring” taste. After drinking MT3water for only a few days, one would find it verydifficult to go back to drinking tap water. Thetaste buds become more acutely aware of thebad taste of chlorine and other impurities in tapwater.

Question: Do you use any charcoal in yourMT3 RO?

Answer: Yes, we use an activated carbon fil-ter of high capacity on the product water side ofthe Membrane, in other words, our carbon filteronly deals with water that has already passedthrough the RO membrane and been purified.The activated carbon removes any vestige oftaste and odor as well as any remaining or-ganics that might possibly remain in the waterand gives a “high polish”, which is the reason ithas such a “crystal clear” appearance.Question: How would I know that my MT3 RO

is removing the dissolved solidsfrom the tap water?

Answer: You will be able to tell by taste andby the clarity of the water. For example, icecubes made with RO water are harder andclearer and last much longer. If you will taketwo clean glasses of the same size and put icecubes from MT3 water in one and the samenumber of ice cubes made from tap water in theother, you will notice that it takes longer for icecubes made from Reverse Osmosis to melt.They not only taste better, but they make allbeverages, particularly juices and mixed drinks,taste better. The melted tap water will likelyhave unsightly matter settled on the bottom ofthe glass; not so with MT3 water.

Another way of determining the amount ofdissolved solids removed from tap water,(which are but one type of contaminant), is bythe use of a conductivity meter. This metermeasures the conductivity in parts per million ofTDS. Specially equipped RO faucets, whichmonitor the water quality, are available.Question: I noticed that the scale on the meter

you use covers a wide range. Whatdo these numbers mean?

Answer: A number of the contaminants thatcould be dissolved in our drinking water havehealth consequences. One thing is certain,however, the lower the number on the scale, thebetter tasting will be the water compared withwater containing more dissolved solids. Watercontaining more than 500 ppm of dissolvedsolids is not considered to be the best for humanconsumption. The U.S. Public Health Service

has stipulated that water for drinking and cook-ing should not exceed 500 parts per million andthis limitation has been endorsed by the Envi-ronmental Protection Agency in the SecondaryStandards of the Drinking Water Act. Unfortu-nately, there are vast areas of the United Stateswhere the water exceeds the U.S. Public HealthService limitations by a considerable amount.Question: Does the conductivity meter meas-

ure everything that is in the sourcewater?

Answer: No, there are certain elements thatmay be present in water that are non-ionic, inother words, they do not conduct electricity.These do not show up on a conductivity meter.These elements fall into several groups, butfortunately all are effectively reduced or re-moved by the Reverse Osmosis membrane.Even a properly maintained unit that shows adeclining rate of TDS rejection after a couple ofyears of use will still be an effective barrier tothese substances.Question: What specifically are these non-ionic

substances?Answer: They include: chlorine, radioactivematerials, bacteria, virus, Giardia, Chrysto-sporidium, pesticides, fertilizer, herbicides, or-ganic materials ( industrial waste) andparticulate matter (dirt, asbestos fibers, etc.).Question: What can be done to improve drink-

ing water sources so that they willconform to U.S. Public Health Serv-ice stipulations?

Answer: We are, unfortunately, confrontedwith a serious challenge in trying to raise mu-nicipal water standards. To upgrade all thewater used in the United States to safe drinkingstandards would cost billions of dollars.

Back in the early 1900’s as the U.S. grew veryrapidly, there was one epidemic after another oftyphoid fever, cholera and other diseases com-municated through municipal water systems. Tocombat these epidemics we started introducingchlorine into our water systems in approxi-mately 1908. In the decade following and in-creasingly in the early 1920’s the addition ofchlorine became standard treatment in mostevery municipal water system. It did kill the

bacteria and typhoid fever was almost com-pletely eliminated. However, modern re-search now indicates that chlorine is aninsidious killer and many learned doctors andmedical researchers consider it as the chemicalresponsible for the increase of cardio-vasculardiseases.

The latest research conducted by the Na-tional Academy of Sciences for the EPA indi-cates that when chlorine combines with organiccompounds in water, it produces chloroformtype compounds and trihalomethanes. Theseparticular compounds are believed to be car-cinogens. It seems what once was a blessing,ridding us of typhoid fever and other epidemicdiseases, may now be causing the deaths ofmany Americans every year.Question: What percentage of the water sup-

plied by a municipal water treatmentplant is actually consumed by thepeople?

Answer: That is an important question. Thefact is that we consume only about 1/2 of 1% ofthe total water supply. The rest is used inbathing, flushing toilets, fighting fires, cleaningstreets, watering lawns, industrial use, etc. Itdoesn’t make a great deal of sense to treat allof the municipal supply to optimum drinkingwater quality for such a small percentage of use.Point-of-use water treatment is the most practi-cal method of ensuring that your family has thepurest, good tasting water.Question: How much pure water will the MT3

RO produce?Answer: Various models of the MT3 Systemare available producing between 10 and nearly100 gallons per day, depending on the per-fomance factors listed on page 5.Question: What may limit the application of an

MT3 RO system?Answer: The unit must be installed on a pota-ble supply (no bacteria). Even though themembrane will normally reject bacteria and vi-rus, any imperfection in the membrane or its agecould pose a problem. Water containing veryhigh TDS may require a commercial type ROsystem including a pump, which produces

higher pressure than is available in a domesticsupply.Question: Are there any norms or standards

that have been established forevaluating the performance of a Re-verse Osmosis membrane?

Answer: Yes, the norm on which the perform-ance of a home type Reverse Osmosis Appli-ance is predicated is 50 lbs. water pressure, 500TDS, and a 77° temperature. When the in-coming water temperature is cold, almost downto freezing for example, the production rate of amodule drops considerably, but the TDS rejec-tion rate rises slightly. The same thing appliesto abnormally low water pressure except thatboth output and purity drop. This is why cer-tain conditions of use have been set forth in theMT3 RO Guarantee. In general, the three fac-tors that influence the performance of an ROmembrane are temperature, water pressureand the TDS of the source water. For exam-ple, every temperature degree below 77° is thesame as approximately a 2% drop in net pres-sure. For every 100 parts per million of TDSthere is a loss equal to about one pound persquare inch of pressure. This is all quite tech-nical, however, and usually of interest only tothose involved in the precise evaluation of mem-brane performance.Question: What is the ratio of wastewater to the

pure water produced by an MT3RO?

Answer: The proper ratio to insure long mem-brane life is about 4 to 1. MT3 RO units arepre-set to this ratio at the factory. Therefore,for every gallon of pure water produced, ap-proximately 4 gallons of wastewater go downthe drain.Question: Isn’t that a lot of water that is wasted

down the drain?Answer: Are you concerned about the cost orare you concerned from an ecological stand-point? If you are concerned about cost, it’s asmall matter. Using an average of a gallon perday of RO water will add less than 50 cents toyour monthly water bill, depending on localwater and sewer rates. That’s not much to payfor pure water for drinking and cooking. Inci-

dentally, did you know that some bottled wateris made by reverse osmosis? It may be la-beled “Spring Water”, but, in many instances, alarge industrial reverse osmosis unit makes it.The MT3 RO is simply a smaller reverse osmo-sis system producing pure water in your homefor a few cents per gallon. Bottled water boughtin stores can be rather expensive. Bottled waterdelivered to your home is considerably moreexpensive. In addition, you have to wrestle withthe heavy bottles. If you are bothered aboutthe wastewater from an ecological standpoint,we are not talking about a lot of water. Also,keep in mind that one has to pay a price for purewater just as one pays for everything else.However, there are many ways that ecological-minded people can save important quantities ofwater.Question: Can this water be saved and used?Answer: Yes, by simple plumbing, this watercould be diverted to storage containers or someform of catch basin. It really is just plain waste-water and could be used to wash the family car,although it might precipitate water rings andspots.Question: What are some of the ways that

water can be conserved around thehome?

Answer: Here are a few examples:1) 70% of the water inside the average home

is used in the bathroom, where one ofhistory’s biggest water wasters inperched-the toilet. Although only two-and-a-half gallons are actually needed,the typical American toilet uses anywherefrom three to six gallons per flush-and weflush as though it were the only way todiscard things. Throw in a facial tissue,flush the toilet; throw in a cigarette butt,flush the toilet. Each day, we flush away29 gallons of water per person-more thanfive times the amount a person living in apoor country uses for all purposes in awhole week.

2) Don’t leave water running while brushingyour teeth. Several gallons of water canbe lost down the drain in a hurry.

time. (SEE Parts List) Or, if more convenient,the appropriate tee can be added in the line atanother point.

See Fig. 5 to complete steps A thru D below:

A. Connect 3/8" Blue line from the Faucet tothe Manifold “Faucet outlet”

B. Connect the 1/4" Red feed line from theSupply Saddle Valve to Manifold “IN”.

C. Connect 1/4" OD Black Drain Line fromMembrane Housing elbow to the drain

saddle fitting. The flow control end at-taches to the Membrane Housing.The reject line should be connected to thedrain pipe above the trap.

D. Connect 3/8" OD Yellow line from the“Tank connection” on the Manifold to theball valve on the Storage tank.

8. Start-up Procedure A. Open the Supply Saddle Valve and imme-

diately check for any leaks. Correct anyevident problems.

B. Disconnect the tube at the Drain Saddlefitting and verify the flow of reject water.

C. The Storage Tank may be partially filledwith water prior to start-up with the use ofa 1/4" x 3/8" adapter connected to thesupply line, this will provide flow from theFaucet soon after installation. Otherwise,water will not flow from the Faucet forapproximately 30 minutes.

D. At this time open the Faucet for about 1minute. Check for leaks above and belowfaucet.

E. Close the Faucet and re-inspect the entiresystem for leaks.

F. As late in the day as possible, e.g., justbefore retiring, open the faucet and drainthe storage tank completely until faucetjust drips. Close faucet.

G. If an icemaker has been connected to theMT3, leave its lever or switch in the “off”position and turn it on the following morn-ing when the tank will be full.

3) It is estimated that the average showertakes 20 to 30 gallons. Those who luxu-riate in a hot shower or a cold one on a hotsummer day will let as much as 40 to 50gallons of water go down the drain. Youcould install a flow control in the shower-head to save water.

4) When cleaning vegetables, most peoplewill let the cold water run at a fast rate.This can waste many gallons of water.

5) Buy a pistol grip valve nozzle for the hose.This permits the instant turning on and offof water while washing the family car.Letting the hose run as most people dowhile they are sudsing the car can wastemany gallons of water. A 3/4" hosepours out approximately 180 gallons perhour.

6) After a heavy rain, don’t permit the auto-matic timer to turn on the sprinklers anddon’t let the sprinkler system run exces-sively. In some neighborhoods at lawnwatering time the street curbs becomeveritable rivers of wasted water. Oneway to preserve the important groundwater would be to prohibit the constructionof new golf courses. Golf courses arebeautiful and benefit only a few hundredpeople. However, the irrigation waterused daily would support a fairly largecommunity. With ground water levels inmany areas lowering every year, ecolo-gists should give this a lot of thought.

Question: Does the water pressure have agreat deal to do with the module’sTDS rejection rate?

Answer: Yes. The greater the water pressurethe greater the rejection rate of TDS and moreproduct water is produced. In large commercialsystems, for example, normal city water pres-sure is stepped up as much as several hundredpercent by high-pressure pumps. When thewater pressure reaches high levels the TDSrejection rate rises as high as 99% and thevolume of product water produced rises dra-matically.Question: How often does the Reverse Osmo-

sis membrane have to be changed?

Answer: This is, of course, related to the qual-ity of your tap water. However, in general, anRO membrane will last from two to four years ormore when processing average municipalwater. There are certain conditions of use asspecifically set forth in our guarantee, whichmust be met. However, these conditions fall wellwithin the parameters of most city water sys-tems.Question: How often does the activated carbon

filter have to be changed?Answer: The activated carbon filter or filtersusually do not have to be changed but once ayear. It is customary to replace the pre-filterand carbon filter at the same time.Question: Why can’t giant reverse osmosis

systems be used in municipal waterplants?

Answer: Indeed, some municipalities in Flor-ida have source water loaded with dissolvedsolids.

They provide a blend of RO and filteredground water to their customers.Question: What with the limitation or outright

banning of certain substances byour government, it seems that al-most everything one eats and drinkstoday may be harmful.

Answer: It is a deep concern. The NationalCancer Institute and the World Health Organi-zation estimate that up to 90% of all cancer iscaused by contaminants in the water we drink,the food we eat and the air we breathe. How-ever, we can do various things to safeguard ourhealth. We can drink good water and we caneat good food. It’s difficult to control the air webreathe, but even that can be improved.

INSTALLATION INSTRUCTIONS

Assembly and Use of the Tubing Connectors Used on thisDrinking Water System

Assembly Instructions:1. Carefully trim tubing to length, be sure

tubing is free of debris, nicks orscratches which may cause the fittingsto leak past the O-ring seal.

2. Firmly insert the tubing into the fitting, becertain tubing goes past the O-ring sealand properly bottoms in the fitting

(see diagrams). The fitting will grab thetubing and hold and seal it in place.

3. To remove the tubing, push the colletaround the tubing in and, at the sametime, pull out the tubing.

INSTALLATION INSTRUCTIONSNote: Install only on a potable water supply. 1. Prepare the area for installation.

Check for existing or potential leaks and cor-rect. Provide adequate working light.

2. Determine the desired location for thecomponents. A. Faucet (See “Install the Faucet”, step

#5)Convenience should be the first considera-tion followed by a neat, no mess waterfallpattern into the sink. Try to avoid installingthe faucet where it will be difficult to gainaccess from under the counter.The faucetcan be installed in the existing spray hoseor other opening if this is convenient. If noexisting holes can be used, it will be neces-sary to drill a hole at the desired location.Porcelain and ceramic sinks should bedrilled with extreme care. A carbide ma-sonry drill is recommended through thesurface covering and a high speed drillthrough the metal. It is helpful to use tapeover the complete drilling area.

B. Storage TankLocate for easy access, but an out of theway place is acceptable. It is not recom-mended to dismantle any plumbing ordrains to locate the tank. Remember thatwith 1 gal. the tank will weigh up to 14 lbs.when full, so, place it on a secure founda-tion. The tank can be laid on its side.

C. Purification UnitA good location is on an accessible side orrear wall of the cabinet. Place where youcan get at it for easy, trouble-free service,especially to replace the pre-filter and post-filter.The system can be installed in thebasementNOTE: Due to the compactness and con-figuration of the RO Unit, it can be easilydisconnected and removed for servicewhen there is no choice but to put it in tightquarters.

3. Install the supply saddle valveThe Supply Saddle Valve (SEE Fig. 6) mustbe installed on a cold water line. Be sure waterhas been turned off to the line where thesupply saddle valve is to be installed. The

supply saddle valve is designed to fit onto 1/4"through 1/2" copper pipe. Position supply sad-dle valve on pipe and tighten clamp screws.Turn Yellow Knob clockwise to pierce pipe.Back out the Yellow Knob all the way formaximum flow. If flow is restricted, it may benecessary to drill out hole in pipe using a 1/8"drill bit.

4. Install the Drain SaddleThe Drain Saddle (SEE Fig. 6) should beinstalled above the drain trap and can beinstalled in a horizontal or vertical drain line.The hole into the drain should be 1/4" diame-ter. If installed on a horizontal drain line, besure to drill hole on the upper side of the drainpipe. Local codes may require a non-saddleconnection to drain.

5. Install the Faucet. A. Prepare the mounting hole.

1.Select a mounting location that providessufficient surface area to accommodatethe faucet base on top of the mountingsurface (approximately 2" diameter) andthe Black Locating Washer below themounting surface.

2.Drill or cut a mounting hole in the desiredlocation in accordance with faucet manu-facturers instructions. Remove all burrsand sharp edges. Note: Thickness ofmounting surface should not exceed 1".If thickness is greater, an extension pipeand connecting adapter must be used.

C. Install faucet on sink. 1.Making sure Escutcheon Plate and Black

Rubber Washer are assembled on thethreaded mount tube as shown in Figure5, insert faucet assembly through hole insink. Orient the Black Locating Washeraccording to Figure 5 and slide it onto thethreaded mount tube along with LockWasher, then screw on the Lock Nut. Donot tighten at this time.

2.Position Faucet on top of sink and orientfaucet according to homeowner prefer-ence.

3.Hold Faucet in place and reach undersink to tighten Lock Nut. Be sure faucet
