- WHAT YOUR REVERSE OSMOSIS SYSTEM WILL DO -

Your Reverse Osmosis (RO) Drinking Water System
is a water treatment unit. It uses household water
pressure to reverse a natural physical process called
osmosis. Water, under pressure, is forced through a
semi-permeable membrane where minerals and im
purities are filtered out. Clean drinking water goes to
the faucet or storage, while minerals and impurities
are sent to the drain with RO waste water. The miner
als and impurities are measured in water as

total dis

solved solids (IDS).

The system includes replaceable pre and postfilter
sediment-carbon cartridges. The prefilter removes
sand, silt, dirt, rust particles, other sediments, and
chlorine from the water supply before it can enter the

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
automatic shutoff valve closes when the RO faucet is
closed and the storage tank is full.

Your reverse osmosis system gives you a continuous
supply of sparkling clear, delicious water for drink
ing, cooking and other uses. Foods will look and
taste better too. Having high quality RO product wa
ter 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 -

FOR OPTIMUM PERFORMANCE YOUR KEN­MORE REVERSE OSMOSIS SYSTEM SHOULD BE
INSTALLED ON SOFTENED WATER.

CAUTION: A refrigerator icemaker may not operate

properly when connected to a reverse osmosis sys
tem that has been installed on a water system that op
erates outside of the specified pressures listed on
page 16.

Check Your Water Supply: The cold water supply to

the RO system must be within certain quality limits.
See the specification table on page 16. If supply water
is not within limits, the RO system can not make
product water as it should and reduced RO mem
brane life will result.

Trained sales people at Sears can arrange for a free
water analysis. The analysis will tell you if other wa
ter supply treatment is needed before going to the
RO system.

CAUTION: Chlorine in the water will destroy the
RO membrane- Most cities add chlorine to the wa

ter supply to kill bacteria. The prefilter removes
chlorine up to the limits shown in the specifications
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 16.

Check Parts Included: Unpack the carton and re

move 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 the sink, usually in the kitchen or
bathroom. The RO assembly mounts on a wall sur
face, or can lay on the cabinet floor next to the storage
tank. Hanger washers and wood screws are included
for cabinet wall mounting. The RO product water
faucet installs on the sink, or on the countertop next
to the sink (pages 6 and 7).

Note: Tubing lengths allow for the removal of the
assembly from the hanger washers for servicing. If
tubing lengths are shortened for neater appear
ance, it may be necessary to keep the assembly on
the hanger washers for service.

You can also locate the RO assembly and storage tank

FiG-2

in any remote location from the faucet, observing
safety guides on page 2. You do need a nearby water
source and drain point (see page 17).

Water Supply: To provide supply water to the RO

system inlet use the included feed supply fitting or
install pipe fittings for tubing connection, as typical
ly shown on page 5.

Drain Point: A suitable drain point is needed for re

ject water from the RO membrane. A floor drain,
laundry tub, standpipe, sump, etc., is preferred, as

shown in the remote locations drawing, page 17. A
sink p-trap drain adaptor is included to install where
codes permit, as an optional drain point (page 6).

- STEP 1: INSTALL COLD WATER SUPPLY FITTING -

Check and comply with local plumbing codes as you plan, then install a cold feed (supply) water fitting. The

fitting must provide a leak-tight connection to the RO 1/4" tubing (see FIG. 8, page 8). A typical connection
using the included water supply fitting is shown in F1G.3 - A below. An optional connection, using standard
plumbing fittings (not included), is shown in B.

Note: Codes in the state of Massachusetts require installation by a licensed plumber, and do not permit the use of a saddle
valve. For installation, use plumbing code 248- CMR of the Commonwealth of Massachusetts.

A. WATER SUPPLY FITTING B. OPTIONAL PIPE FITTINGS (compression type

l.Closethe house main water shutoff valve and open shown)
faucets to drain water from the sink cold water pipe.

2, Remove nut that connects the cold water faucet to
cold water plumbing.

3, Use pipe joint compound or Teflon tape on cold water
faucet stud threads and on the male threads of the water
supply fitting that connect to the cold water pipe,

4, Thread water supply fitting onto pipe and recoimect

nut to bottom of fitting.

Note: Be sure to turn off the water supply and open

a low faucet to drain the pipe.

Complying with plumbing codes, install a fitting on
the kitchen cold water pipe to adapt 1 /4" OD tubing.
A typical connection is shown in figure 3B. If
threaded fittings are used, be sure to use pipe Joint
compound or Teflon tape on outside threads.

- STEP 2: INSTALL DRAIN ADAPTER -

■ Note: Running the drain tubing directly to a floor
drain, sump, standpipe, laundry tub, etc., as shown
on page 17, is preferred. However, if that is not pos
sible or practical, the included drain adapter installs
in the sink drain pipe, always above or ahead of the
p-trap (FIG. 4). Be sure to comply with your local

plumbing codes. Other drain pipe fittings, in addi

tion to the adapter, may be needed.

■ The drain adapter fits 1-1/2" sink drain pipe.

■ The adapter installs directly onto the sink tailpiece
as typically shown in FIG. 4 and 5.

■ Locate so drain tubing from the faucet (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

connector to the drain adapter (FIG. 5). Turn the con
nector to about 45“ from the 12:00 position, as shown
(to 10:00 or 2:00 position as needed), lighten 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 can cut to shorten
the unthreaded end of the adapter. Do not cut too

short so the adapter will make a leak-tight seal with

the connecting fitting.

4. Assemble the p-trap to the drain adapter, and oth

er drain pipe fittings as required (check codes) to
complete the drain run.

5. Tighten all connections, but do not overtighten and
break plastic fittings.

- STEP 3: INSTALL FAUCET -

A. PREPARE MOUNTING HOLE

1. Select one of the following places for the faucet. Be
sure it win 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 1-1/8" to 1-1/4" diameter hole is

needed.

^ 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 re
pair, consult a qualified plumber or installer for

guides to drill holes in porcelain or stainless steel.

2. If drilling is needed, make the 1-1/ 8" to 1 -1/4" di
ameter hole.

3. Place plumbers putty around the drilled hole (FIG.

6) to prevent water leakage around the base of the
faucet.
