- 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
solved solids (TDS).
The system includes replaceable pre and postfilter
sediment-carbon cartridges. The prefilter removes
sand, sût, dirt, rust particles, other sediments, and
chlorine from the water supply before it can enter the
total dis
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.
Check Your Water Supply: The cold water supply to
the RO system must be within certain quality limits.
See the specification table on page 15. 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 salespeople 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 14.
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
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 18).
Water Supply: To provide supply water to the RO
system inlet, install pipe fittings for tubing connec
tion, as typically 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 18. A
sink p-trap drain adaptor is included to install where
codes permit, as an optional drain point (page 6).
- TOOLS AND MATERIALS NEEDED -
► adjustable wrench, standard pliers, and larger
adjustable jaw pliers or pipe wrench to fit sink drain
► slotted and Phillips head screwdrivers
► plumbers putty
- 6 STEPS TO INSTALL -
STEP 1: - Install Cold Water Supply fittings - page
5
STEP 2: - Install Drain Adapter - page 6
STEP 3: - Install Faucet - pages 6 and 7
► pipe joint compound (thread seal) approved for
use on potable water supplies
► electric drill and bits, if hole is needed for the RO
faucet, page 6 and 7
STEP 4: - Install RO Assembly - page 7
STEP 5: - Install Storage Tank, Make Remaining Tub
ing Connections - page 8
STEP 6: - Sanitizing, Pressure Testing, Purging page 9
- 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 FIG.3 - A below. An optional connection, using standard
plumbing fittings (not included), is shown in B.
A. WATER SUPPLY FITTING
1. Close the house main water shutoff valve and open
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 reconnect
nut to bottom of fitting.
FIG.3 A. WATER SUPPLY CONNECTION
(using included water supply fitting)
B. OPTIONAL PIPE FITTINGS (compression type
shown)
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 18, 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). 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 can cut to shorten
the unthreaded end of the adapter. Do not cut too
short so the adapter wfll 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 1 of the following places for the faucet. Be
sure it wiU 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 is need
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 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" to 1-1/4" diame
ter hole.
3. Place plumbers putty around the drilled hole (FIG.
6) to prevent water leakage around the base of the
faucet.
