SECTION I. INTRODUCTION

Congratulations, you have just purchased one of the finest Reverse Os mo sis Drinking WaterAppliances avail able.

Like any other fine product, this ap pli ance requiresperiodic maintenance in accordance with the sched-ule outlined below.

Recommended Filter Change Schedule*

1 - Pre-filter, 10", 5 Micron 6 Months

2 - Granulated Activated Carbon 6 MonthsPost-filter

3 - Reverse Osmosis Membrane 24 - 36 Months

4 - Pre-Carbon Filter For Chlorine 6 MonthsRemoval

5 - Inline Carbon Adsorbtion Filter 6 Months

*Based on standard conditions.

Your new Reverse Osmosis (R.O.) Drinking Wa tersys tem uses a combination of filtration tech nol o giesto reduce unwanted contaminants in a water sup ply.The following steps combine to give you the best inclear sparkling drinking water:

MECHANICAL FILTRATION - The sediment pre-fil-ter will remove the larger particles such as silt, rustand scale. Its 5 micron (equal to 0.0002 inch) nomi-nal rating helps to give maximum life to the R.O.Mem brane and carbon filter.

ACTIVATED CARBON PRE FILTER(S) - The activat-ed carbon in a pre-filter will remove any chlorinethat may be present in the feed water. This pre-treatment is also necessary for membrane pro tec -tion in chlorinated water.

REVERSE OSMOSIS MEMBRANE - The R.O. Mem -brane is the heart of the filtration system. It isdesigned to reduce the dissolved mineral content of thewater. Minerals picked up in the environment by thewater are measured as Total Dissolved Solids (T.D.S.).In the Reverse Osmosis process, dissolved min er alsare sep a rat ed from the incoming water (Feed Wa ter) topro duce the product water (the Permeate). The excessminerals are rinsed to drain (the Reject Water). Thespiral wound construction of the R.O. Membranepro vides max i mum surface area for water produc-tion and is less sus cep ti ble to fouling by par tic u latematter, turbidity and col loi dal materials.

ACTIVATED CARBON POST FILTER - The Ac ti vat edCarbon Post Filter cartridge contains carbon parti-cles with a vast network of pores. The tre men doussurface area of these pores (typically 800-1200square meters per gram of carbon) gives the carbonvery good ad sorp tive sites for chlorine as well asother substances that contribute to tastes andodors. The product water from the membrane aswell as the holding tank passes through theActivated Carbon Post filter on the way to theDispensing Faucet. The Activated Carbon PostFilter reduces tastes and odors that may passthrough the system. It adds a final “polish” to thewater.

INLINE CARBON ADSORPTION FIL TER - This slowflow carbon filter is designed to reduce certainorganic compounds and chloramines.

AUTOMATIC SHUT-OFF VALVE - The A.S.O. Valve sens es when the product water tank is fulland clos es the feed water supply to prevent excessreject water from going to drain when the unit is notpro duc ing water.

SECTION II: PREPARATION

A. Major System ComponentsThe following components comprise the R.O. Drink -ing Water System

1. A Reverse Osmosis assembly consisting of thewhite alu mi num bracket, filter hous ings, auto-matic shut-off, mem brane module and an in-line carbon filter.

2. A drinking water holding tank.

3. A faucet kit.

4. A plastic tubing kit with self-piercing saddlevalve and drain clamp.

5. Other items necessary for installation mayinclude wood screws or ma chine screws formounting the R.O. assembly, or concrete an -chors for hang ing on base ment wall, addition-al tubing or tube con nec tors, plastic wire tiesfor or ga niz ing tubing.

Note: For systems equipped with Quick Connect fit-tings, see last page.

B. Tools Recommended for In stal la tionThe following tools will cover most of the in stal la -tion sites encountered:

• 3/8" variable speed electric drill.• Extension work light with outlet.• Safety Glasses.• 1-1/4" porcelain hole cutter kit.• 1-1/4" Greenlee hole punch and 1/8" and 1/2"

metal drill bits for pilot hole.• Center punch and hammer.• 1-1/4" wood bit.• Assorted wood and metal drill bits including

7/32" metal drill bit.• Phillips head and flat blade screwdrivers.• 1/2", 9/16" and 5/8" open end wrench.• 10" Crescent wrench with jaws taped to hold

faucet.• Teflon tape.• Wide masking tape or duct tape.• Plastic tubing cutter.• Extra plastic tubing.• Low range air pressure gauge.• Bicycle hand air pump.• Small bottle of liquid chlorine bleach.

C. Determine System LocationThe R.O. system can be located under a sink or in abasement depending on space availability and thecus tom er’s preference. If a basement installation isse lect ed, additional tubing, hardware and fittingsmay be needed and a hole will have to be made fromin side the cabinet, through the floor, to the basement.Nev er install in an area of the home where tem per a -ture is freezing as damage to the system will result.

Considerations for an ice maker or other remotehook up should be determined, including rout ing andany ad di tion al tools, fittings, and tub ing that maybe re quired.

1. Faucet - The faucet should be placed near thesink where drinking water is normallyobtained. Con ve nience of use (filling of waterpitchers and glass es), and an open areabeneath the faucet under the sink for attachingproduct tubing are considerations. A 2" di am e -ter flat surface is re quired above and be low themounting site. The thick ness of the mount ingsurface should not exceed 1-1/4". Watch forstrengthening web bing on the un der side of castiron sinks.

2. Drinking Water Holding Tank - The hold ingtank may be placed where it is convenientwithin 10 feet of the faucet, under the sink orin an adjacent cabinet are best choic es. If alonger run of tubing is required, the tubingshould be the 1/2" di am e ter O.D. size to pre -vent a high pres sure drop. Re mem ber, thesetanks can weigh up to 30 pounds when full ofwater , a firm, level area is required.

3. R.O Assembly - The R.O. Assembly may bemount ed on either the right or left side of theunder-sink area or a cabinet. Mounting in thebasement is also an option, one possible loca-tion is near the laundry /utility sink where coldpotable water and drain access is handy. Themounting location should allow adequate clear -ance and ac ces si bil i ty for car tridge changes.

4. Feed Water Connection - The self-pierc ing feedwater shut off valve should be located as closeto the R.O. as sem bly as possible. USE APOTABLE COLD WA TER SUPPLY ONLY.Softened water is pre ferred as it will ex tendthe life of the R.O. Mem brane.

5. Drain Connection - The drain saddle assemblyis designed to fit around a standard 1-1/2" ODdrain pipe. The drain saddle should always beinstalled above (before) the trap and on thevertical or hor i zon tal tail piece. Never installthe drain saddle close to the outlet of a garbagedisposal or plug ging of the RO drain line mayoccur. If discharging into an util i ty sink orstandpipe, an air gap of greater than 1" abovethe flood rim must be pro vid ed. Do NOT con-nect the system drain line to the dishwasherdrain or near the garbage disposal.

D. Prepare The Area For InstallationTo save time it is often advised to call the customerand request they clear under the sink prior toarrival. Oth er wise, remove supplies from under thesink and stack them neatly away from the work ingarea. Ar range a light for the work area, if necessary.

If a basement installation is called for, de ter minewhere components will be located and how they willbe mounted. Special mounting brack ets and hard-ware may be nec es sary to secure the system to awall or ceiling joists.

Inspect cold water supply line and drain to de ter -mine if any special fittings, in addition to what isincluded in the kit, are required.

E. Prepare The Appliance ForInstallation

Open shipping carton and remove com po nents.Check that all installation parts are present whichincludes the purification assembly, storage tank,fau cet, installation hard ware and tubing.

Check that the air supply in the empty tank is ap -prox i mate ly 7 psi. Adjust if necessary.

SECTION III: INSTALLATION STEPS

All plumbing should be done in accordance withstate and local plumbing codes.

NOTE: Some codes may require installation by alicensed plumber; check with the local plumbingau thor i ty prior to installation.

In restricted under-sink areas, it may be easier toinstall the faucet first. Allow adequate tubinglengths for any final component position.

A. Install The FaucetSee Figure 1 for Faucet Installation Diagram

The customer should be consulted before de ter min -ing faucet location. The faucet should be po si tionedso that it empties into the sink and the spoutswivels freely for con ve nience.

If the sink already has a hole provided that can ac -com mo date the RO faucet, then no drilling is re -quired and you can proceed to the section on mount-ing the faucet.

1. Make The Faucet Mounting HoleIMPORTANT: It is mandatory that safety glass esbe worn during sink hole drilling operations to pre -vent eye injury.

Before starting the hole making operation, alwayscheck below the sink so that nothing interferes withmount ing the faucet such as reinforcing ribs, sup-port brack ets or cabinet construction.

STAINLESS STEEL SINK:

Recommended tools:• Center punch• Variable speed drill and high speed drill bits.• Greenlee chassis punch 7/8" hole size (alternate

9/16" size may be used for non air gap faucet)• Protective gloves

Procedure:a) Center punch a small indent at the desired

faucet lo ca tion.b) Slowly drill the required pilot hole for the

chassis punch.c) Set up the chassis punch per in struc tions and

tighten nut to cut the desired hole size.d) Clean up sharp edges with a file if necessary.

PORCELAIN/ENAMEL/CERAMIC ON SHEETMET AL OR CAST IRON BASE:

Recommended tools:• Variable speed drill• Relton porcelain cutter tool set 7/8" size (al ter -

nate 9/16: size may be used for air gap or nonair gap faucet)

• Plumber’s putty

It is important to understand what is in volved inthis procedure. First, the glassy layer of porcelainmust be penetrated through to the base metal.Second, a center disc of porcelain must be re movedwhile pro tect ing the sur round ing porcelain againstchip ping or fracturing. Third, the base metal mustbe drilled through to com plete the hole.

Procedure:a) Mark the center for the 7/8" holeb) Form shallow putty dam around hole area

and fill with enough water to lubricate carbidedrill bit.

c) Carefully drill pilot hole through por ce -lain/enam el and base metal using carbide typepilot drill.

IMPORTANT: Always operate drill with lightpres sure at slow speed (300-400 rpm).

d) Insert pilot tip of spring-loaded por ce lain cutter into pilot hole.

e) Drill porcelain/enamel using spring-load edpor ce lain cutter, making certain a com pletering has been cut through the por ce -lain/enamel to the metal base.

f) Change to the metal cutter. With slow speedand light pressure, cut away the inner por ce -lain/enam el disc down to base metal. Makecertain that the cutter does not touch out er rim of the cut porcelain/enamel. Con tin ue withthis bit to cut through metal until sink hasbeen completely pen e trat ed.

IMPORTANT: When using a porcelain cutter it is critical to take precautions that it is always in a sharp ened condition. Dull cutters are known tochip sinks.

2. Mount The Faucet:a) Familiarize yourself with all com po nents

shown in the faucet diagram.b) Disassemble hardware from the threaded

nipple, except for chrome base plate and rub-ber washer.

NOTE: Rubber washer may be replaced withbeadof plumber’s putty for neater ap pear ance.

c) Connect length of standard 1/4" tub ing tofaucet. Push on firmly until it seats.

d) Feed the threaded nip ple through sink/countermounting hole and orient the faucet as dis-cussed with the customer.

e) From below sink/counter assemble the blackplastic washer, star washer and hex nut onthreaded nip ple and tighten by hand.

f) After rechecking faucet orientation, tighten hexnut (9/16" wrench or deep socket) until faucetfeels secure.

g) From above the sink make any minor ori en ta -tion cor rec tions by turning the faucet with apadded adjustable wrench.

Note: Flats on chrome faucet may be used fortight en ing with an adjustable wrench. Use carenot to mar chrome finish.

B. Install the Feed Water Valve andTub ing

The saddle tapping valve supplied is de signed foruse with 3/8" to 1/2" OD soft copper supply tubing(plain or chromed), rigid metal pipe, or CPVC plas-

tic pipe. Do not use with flexible ribbed supply tub-ing which has too thin a wall thickness and requiresspecial hard ware.

Saddle Valve Installation

SOFT COPPER TUBING INSTALLATIONS:1) Turn off cold water valve under the sink, or

main valve for the house.2) Before installing saddle tapping valve, make

sure pierc ing lance does not protrude be yondrubber gasket.

3) Assemble saddle tapping valve on copper tub-ing. Tighten clamp.

4) To pierce soft copper tube, turn handle clock -wise until it is firmly seated. The valve isclosed in this position.

5) Turn on main supply valve to pressurize coldwater line. Check for leaks. With a wrenchsnug nut/seal around valve stem.

NOTE: For basement installations the existingfeed water tubing may have to be longer to reachfeed valve.

6) Connect one end of the tubing to the feedwater valve using brass compression nut andplas tic sleeve.

RIGID METAL PIPE AND CPVC PLASTICPIPE INSTALLATIONS:

1) Turn off cold water supply valve and drain theline to prevent spillage.

2) Drill 3/16" hole at the desired location. To pre-vent shock hazard, use a battery op er at eddrill.

3) Before installing saddle tapping valve, makesure pierc ing lance does not protrude be yondrubber gasket.

4) Assemble saddle tapping valve on copper tubing. 5) Turn saddle valve handle clockwise to close

valve. With a wrench tighten nut/seal aroundvalve stem.

6) When you wish to open valve and supply cold water to the unit, turn valve handle coun ter clock wise.

7) Connect one end of the tubing to the feedwater valve using brass compression nut and plas tic sleeve.

NOTE: For basement installations the existing feed water tubing may have to be longer to reachfeed valve.

C. Prefill and Sanitize the Storage Tank Prefilling the tank is always rec om mend ed so thereis pressure to check for leaks and several gallons ofwater to flush carbon post filter. Tanks are fur -nished with a special disinfectant and only re quirefilling with water for 15 min utes to be com plete lysanitized. It is im por tant to use a sanitizer whenprefilling tank so the solution can sanitize the tub-ing, fit tings, and faucet at the time of installationand startup.

1) Insert free end of feed water tubing into thefitting on the stor age tank.

2) Open feed water valve and tank valve andallow tank to fill (about 3 minutes).

3) Turn off feed water valve, tank valve,remove tank from tubing and set tank aside(15 minutes minimum).

D. Install the Drain ConnectionIMPORTANT: Before starting this pro ce dure, in -spect the condition of the drain piping, especiallyin older homes where the traps and tailpieces canbe deceptively thin and frail. If in poor condition,it is wise to inform the customer that the condi-tion should be remedied.

The drain saddle assembly is de signed to fitaround a standard 1-1/2" OD drain pipe.

The drain saddle should always be installed above(before) the trap and on the vertical or horizontaltailpiece. Never in stall the drain saddle close to theoutlet of a gar bage disposal or plugging of the ROdrain line may occur.

1) Peel adhesive covering from the back of foamsquare gasket and line up with the hole in thesaddle drain and apply. This gasket provides aleak proof seal on the drain stand pipe.

2) Position both halves of drain saddle at desiredlo ca tion on drain pipe.

3) Use bolts and nuts to clamp drain saddle ontodrain pipe. Do not over tight en and make surethere is equal space between saddle halves oneach side.

4) Carefully drill hole through threaded fitting of drain sadlle (as shown in Photo 2) beingcareful not to drill through opposite side ofdrain pipe.

5) Wrap teflon tape on thread of fitting, insertdrain tubing into compression nut and tightenonto drain sad dle.

D. Install the R.O. Membrane The RO Membrane has been shipped to you in a spe-cial preservative. Unscrew the tubing from the end-cap of the membrane housing. Then unscrew theend cap from the membrane housing on the appli-ance, insert the membrane as illustrated below. TheO-rings on the product water tube of the membraneMUST FULLY SEAT in the membrane housing forproper operation. Also make sure that the BrineSeal on the membrane seals with no gaps or wrin-kles inside the membrane housing. Once the mem-brane is installed, replace the end cap and reconnectthe tubing.

To insure that all the special preservative is flushedfrom the system before use, DO NOT use the firsttwo tankfuls of water produced by the system.

F. Make Initial Tubing ConnectionsIt is advantageous to make some of the tubing con nec -tions at this time, since the undersink work area is notso cramped and access to the com po nents is easier.

G. Install the Purification Assembly andStorage Assembly

The purification assembly is usually mounted to theright or left sink cabinet sidewall, taking into con -sid er ation the space available and the tank lo ca tion.Generally, the tank is placed in the rear of the cabi-net while the pu ri fi ca tion assembly is positionedtoward the front for cartridge ac ces si bil i ty.

To mount the purification assembly elevate at least2" off the cabinet floor and, while keeping level,mark the lo ca tion of the mounting holes on cabinetsidewall. Make small pilot holes with an awl or drilland screw in the two mounting screws, leaving justenough pro trud ing to allow bracket mounting slotsto slide over them.

NOTE: If the cabinet sidewalls are not of solidcon struc tion, the purification assembly can be seton the cabinet floor and held against the sidewallwith the mounting screws.

The tank may be oriented either vertically or hor i -zon tal ly. It is generally placed to the rear of the cab-inet but can be set in the front center (between thesink basins) for ease of access if space permits.

H. Make Final Tubing Con nec tionsWith all of the components in place, the final tubingconnections can be made. When routing tubingbetween components, several guidelines should beob served.

• Tubing runs should generally follow the con-tour of the cabinets rather than interfere withthe cab i net storage area.

• Strive for neatness and an orderly tubing “flow”using fasteners (e.g. insulated staples) to securethe tubing. Cut tubing to the desired length.

• Arrange the tubing so there are no sharp bendsand leave some “play” in the tubing for ease ofser vic ing.

• Try to keep the tubing from the purification as -sem bly to the tank and faucet as short as prac -ti cal for good flow.

I. Install Ice Maker Hookup (optional)Note: Check with refridgerator manufacturer forcompatibility with your refridgerator model.

The RO drinking water appliance can be con nect edto any standard refrigerator ice maker or icemaker/water dispenser. It should never be connect-ed to a com mer cial type bar ice maker.

Hooking up an ice maker involves connecting a teewith shut off valve into the faucet tubing and rout-ing tubing over to the refrigerator. Do not hook-upto existing copper tubing.

Before turning off the existing tap water sup ply to arefrigerator ice maker, always shut off the ice makerfirst (usually by lifting the lever arm above the binto the up per most position). The ice maker shouldonly be turned on again after the RO system hasbeen drained several times and the tank has a fullsupply of water.

NOTE: Before any service is performed on the ROsystem, always turn off ice maker valve and the icemaker unit. Only turn on when system is operat-ing and tank is full.

J. Start Up the System1) Double check that all connections are secure.2) Turn on feed water valve and check for leaks.

If any leaks are noted, turn off valve and cor-rect before pro ceed ing.

3) Turn on storage tank valve and open faucetuntil a steady stream of water flows. Closefaucet, wait at least 5 minutes and carefullycheck for leaks. Cor rect as nec es sary.

K. Flush System of Preservative andCheck Operation.

1) Lift faucet handle and allow tank to draincom plete ly of sanitizing solution. Do Not UseThis Water. When tank is empty, the faucetwill steadi ly drip. This is the rate water isprocessed by the RO system.

2) With faucet handle in “up” position, measure therate of the steady drip from spout. Use a grad u -at ed cylinder (in milliliters) and watch with asecond hand to calculate approximate produc-tion in gallons per day (mil li li ters per minute X0.38 = gpd). Proceed to check reject flow rate bydis con nect ing tubing at drain con nec tion andmeasure as per above. The ratio should be aminimum of 2.5 (reject) to 1 (product).

3) Close faucet and re-inspect system for leaks.In struct customer to wait at least 4 hours anddrain tank again. The water should be dis-carded as it may contain some pre ser va -tive/dis in fec tant solution.

4) System should be ready to use as soon as thetank refills. If any objectionable taste isnoticed after second tank draining, instructcustomer to wait and drain tank the followingday. Only at this time should an ice maker beturned on if one is con nect ed to the system.

SECTION IV: OPERATION & MAINTENANCE

A. Normal Operation1. It is normal for the Total Dissolved Solids

(T.D.S.) of the water to be higher than normalduring the first 5 gallons of operation, this isdue to the sanitizing solution and the new PostFilter. After this water is rinsed to drain, theremoval rate should stabilize at a valuegreater than 75%. Water pressure affects theproduction rate and quality.

2. R.O. systems produce drinking water at rel a -tive ly slow rates, it can take up to 8 hours ormore to fill the holding tank. Normal opera-tion is to let the Holding Tank fill with waterand then draw water as is needed. When thepressure in the Holding Tank falls to a givenpressure( as the water is being used) theAutomatic Shut Off Valve (A.S.O. Valve) willstart wa ter production and the system willrefill the Holding Tank. When the HoldingTank is full and no water is being used, theA.S.O. Valve will automatically shut off thefeed water to con serve water.

The more water that is used (up to the capacity ofthe system) the better the R.O. system will function.Utilize other uses for the water, such as flowers,pets and rinsing glassware.

After periods of non-use, such as a week’s va ca tion,it is better to empty the holding tank and allow thesystem to produce fresh water for use. If the systemis not used for 3-4 weeks or longer, it is a good ideato re sanitize the system and to change theActivated Car bon and Sed i ment Filters.

B. Changing FiltersNOTE: THIS R.O. SYSTEM CONTAINS FILTERS WHICH MUST BE REPLACED AT REGULAR IN TER VALS TO MAIN TAINPROPER PERFORMANCE. USE ONLY FAC TO RY AP PROVED FILTERS.

Please see Page 1 for the recommended in ter val forchanging the filters. Local conditions may dictatemore frequent changes.

Use a drip pan to catch any water that may spillwhen the Filter Housing are removed.

1) Close the Saddle Tapping Valve by turningfully clock wise and open the DispensingFaucet by lifting the handle. Allow theHolding Tank to empty.

2) Loosen and remove the appropriate FilterHous ing. Discard the cartridge(s).

3) Wash the inside of the Housing(s) using a mildde ter gent and a soft cloth. Do not use abra-sive cleaners or pads. Thoroughly rinse allsoap from the housing before reassembly.

4) To sanitize the system and replace the filtercartridge(s):

NOTE: The system should be sanitized beforeinstalling the Ac ti vat ed Carbon Post FilterCartridge.

a) Use a good quality unscented 5-1/4% liquidbleach such as Clorox.

b) Add one cap full of bleach (this is 2 tsp. or 10ml) to the Sediment Filter Housing. Installthe Sed i ment Prefilter only. Check theHousing O-ring for proper position in itsgroove, replace Sediment Filter Housing onR.O. assembly.

c) If your R.O. system has a Pre Carbon FilterHous ing, add one cap full of bleach. Care ful lyfill the housing with tap water and temporarilyinstall the housing, without the ActivatedCarbon Pre Filter.

d) Add one cap full of bleach to the Activated

Carbon Post Filter Housing. Carefully fill thehousing with tap water and temporarily installthe hous ing, without the Ac ti vat ed CarbonPost Filter.

e) The Dispensing Faucet should be open, slowlyopen the Saddle Tapping Valve on the FeedWater Line.

f) As soon as water begins to drip out of the Dis -pens ing Faucet, close the Faucet.

g) Let the system stand for 15 minutes.h) At the end of 15 minutes, in the following

order, close the Saddle Tapping Valve, closethe Hold ing Tank Valve and open theDispensing Faucet to release the pressure.

i) Remove the Post Carbon Filter Housing andemp ty (Repeat procedure if your system has aPre Carbon Filter Housing). Remove anywrapping/pack ag ing from carbon cartridge (s)and install in hous ings. Check the O-ring to

insure that it is po si tioned properly in itsgroove and replace Housing(s) on R.O. unit.

j) Disconnect the yellow product water tubingthat runs from the Holding Tank. Put 50 dropsof bleach (this is 1/2 tsp. or 3 ml) into the tub-ing and reconnect it.

k) Slowly open the Saddle Tapping Valve. Whenwater begins dripping out of the DispensingFau cet, in the following order, close the Faucetand then open the Holding Tank Valve.

l) Do not open the Faucet for at least 8 hours.m) Discard the first two full tanks of water pro-

duced, they will contain chlorine.n) When the Faucet is first opened, expect air

and carbon fines (very fine black powder),from the new carbon filter (s) to be rinsed out.This is normal for the first tank of water.
