-- WHAT YOUR REVERSE OSMOSIS SYSTEM WILL DO --

Your Reverse Osmosis (RO) DrinkingWaterSystem
is a water treatment unit. It uses household water
pressure to reverse anatural physical process called
osmosis. Water, under pressure, is forced through a
semi-permeable membrane where minerals and im­puritiesarefilteredout.Clean drinkingwatergoesto
the faucet orstorage, while minerals and impurities
aresenttothedrain withROwastewater.Theminer­als and impurities are measured in water as totaldis-
solved solids (TDS).

The system includes replaceable pre and postfilter
sediment-carbon cartridges. The prefilter removes
sand, silt, dirt, rust particles, other sediments, and
chlorinefromthewatersupplybeforeitcanenterthe

RO membrane. The postfilter removes any tastes
and/or odors that may remain in the water, after
passing through the RO membrane, and just before
going to the RO faucet. To prevent water waste, an
automaticshutoffvalve closes when the ROfaucetis
closed and the storage tank is full.

Yourreverseosmosis system gives youacontinuous
supply of sparkling clear, delicious water for drink­ing, cooking and other uses. Foods will look and
tastebettertoo. Havinghigh qualityROproductwa­ter at your fingertips eliminates the need to buy
bottled water.The storage tank holds over 2 gallons
of RO product water for your needs.

-- BEFORE YOU BEGIN TO INSTALL THE RO SYSTEM --

Check Your WaterSupply: The cold water supply to
the RO system must be within certain quality limits.
Seethespecificationtableonpage15.Ifsupplywater
is not within limits, the RO system can not make
product water as it should and reduced RO mem­brane life will result.

Trained salespeople at Sears can arrange for a free
wateranalysis. The analysis will tell you if otherwa­ter supply treatment is needed before going to the
RO system.

CAUTION:Chlorinein the waterwill destroythe
ROmembrane.Most cities add chlorinetothewa-

ter supply to kill bacteria. The prefilter removes
chlorineupto thelimits shownin thespecifications
before it enters the RO membrane. It is important
to replace the prefilter cartridge at least every 6
months. See the RO care guide on page 14.

Check Parts Included: Unpack the carton and re­move the RO system. In addition to the assembled

RO and the storage tank, the system includes the
parts illustrated below, a separate length of tubing,
and this manual.

-- WHERE TO INSTALL THE RO SYSTEM --

The RO assembly and storage tank is designed for
installation under thesink, usually in the kitchen or
bathroom. The RO assembly mounts on a wall sur­face,or canlay onthe cabinetfloornexttothestorage
tank.Hanger washersandwoodscrewsareincluded
for cabinet wall mounting. The RO product water
faucet installs on the sink, oron the countertop next
to the sink (pages 6 and 7).

Note: Tubing lengths allow for the removal of the
assembly fromthehanger washers for servicing. If
tubing lengths are shortened for neater appear­ance, it maybe necessary to keepthe assembly on
the hanger washers for service.

YoucanalsolocatetheROassemblyandstoragetank
in any remote location from the faucet, observing

safety guides on page2.Youdo need a nearby water
source and drain point (see page 18).

Water Supply: To provide supply water to the RO
system inlet, a saddle valve is included to install
(wherecodes permit) onacold water pipe,page5.Pro­videotherpipefittingsfortubingconnection,astypi­cally shown on page 5, where saddle valves are not
allowed.

Drain Point: A suitable drain point is needed for re­ject water from the RO membrane. A floor drain,
laundry tub, standpipe, sump, etc., is preferred, as
shown in the remote locations drawing, page 18. A
sinkp-trapdrainadaptoris includedtoinstallwhere
codes permit, as an optional drain point (page 6).

-- STEP 1: INSTALL COLD WATER SUPPLY SADDLE VALVE --

Checkandcomply with localplumbingcodes as you plan,theninstallacold feed (supply) water fitting. The
fitting must provide a leak-tight connection to theRO 1/4” tubing (see FIG. 8,page 8).A typicalconnection,
using theincludedsaddlevalveisshown inFIG.3 -A below.An optional connection, using standardplumb­ing fittings (not included), is shown in B.

Note:Codesin thestate ofMassachusettsrequireinstal­lation by a licensed plumber, and do not permit the use
of the saddle valve. For installation, use plumbing

code 248-CMR of the Commonwealth of Massa­chusetts.

A. SADDLE VALVE

DANGER(if drilling metalpipe):To protectyour-

selffromserious injuryorfatal shock,use abattery
powered hand drill only to make the hole. Do not
use an electric drill.

align the cutting pin with it. Tighten both screws
evenly, but do not overtighten. Clamp Z will either
have threaded screw holes, or 2 nuts are included.

6. Carefully turn the handle inward to pierce a hole
in the copper or plastic pipe.

B. OPTIONAL PIPE FITTINGS (compression type

Note: Be sure to turn off the water supply and open
a low faucet to drain the pipe.

-- STEP 2: INSTALL DRAIN ADAPTER --

J Note: Runningthe drain tubing directly to a floor
drain, sump, standpipe, laundry tub,etc., as shown
on page 18, is preferred. However, if that is notpos­sible or practical,the included drain adapter installs
in the sink drain pipe, always above or ahead ofthe
p-trap (FIG. 4). Be sure to comply with your local
plumbing codes. Other drain pipe fittings, in addi­tion to the adapter, may be needed.

J The drain adapter fits 1-1/2” sink drain pipe.
J Theadapterinstallsdirectlyontothe sinktailpiece

as typically shown in FIG. 4 and 5.
J Locateso draintubing fromthefaucet(installed in
step 1, page 8) makes a straight run to the adapter,

without dips, loops, low spots or kinks.

Note: Consult a plumber if you are not familiar
with plumbing procedures.

1. Use a ferrule and nut to assemble the drain tubing
connectortothe drain adapter(FIG.5).Turn thecon­nectorto about45_ fromthe12:00position, as shown
(to 10:00 or 2:00 position as needed).Tighten the nut
securely.

2. Carefully disassemble the sink drain pipe and
clean the tailpiece to assure a leak-tight fit.

3. Install the drain adapter onto the sink tailpiece,
using a ferrule and nut. Snug the nut, but do not
tighten.

Note: If needed,to make fit, you cancut toshorten

-- STEP 3: INSTALL FAUCET --

A. PREPARE MOUNTING HOLE

1. Select 1 of the following places for the faucet. Be

sure it will fit flat against the surface, and there is
space underneath for tubing (see FIG. 8, page 8).

' Use an existing sink top hole for a spray hose or
other faucet. A 1”to 1-1/4” diameter hole isneed-

ed.

' Drill a new hole in the countertop next to the
sink.

' Drill a new hole in the sink top.

CAUTION: To avoid damaging a sink beyond re­pair, consult a qualified plumber or installer for

guides to drill holes in porcelain or stainless steel.

2. If drilling is needed, make the 1” to 1-1/4”diame­ter hole.

3.Place plumbersputtyaroundthe drilledhole (FIG.
