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 (TDS).
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. Fiaving 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
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 perform a free water
analysis. This basic test can help determine if any
additional water treatment is required before the RO
system.
CAUTION: Chlorine in the water will destroy the
RO membrane. Most cities add chlorine to the water
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
SOFTENED WATER.
the prefilter cartridge at least every 6 months. See
the RO care guide on page 13.
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.

_ i"Q 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 (page 6).
Note: Tubing lengths allow for the removal of the as
sembly from the hanger washers for servicing. If tub
ing lengths are shortened for neater appearance, 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 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 6: - Sanitizing, Pressure Testing, Purging
- 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 Figure 8, page 8). A typical connection
using the included water supply fitting is shown in Figure 3A below. An optional connection, using standard
plumbing fittings (not included), is shown in Figure 3B.
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.

- 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. Figure 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 Figure 4 and Figure 5.
■ Locate so drain tubing from the faucet 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 (Figure 5). Turn the
connector 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 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 will fit flat against the surface, and there is
space underneath for tubing (see Figure 8, page 8).
^ Use an existing sink top hole for a spray hose or
other faucet. A 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: Drilling holes into countertops made of
stone or solid surface materials such as granite,
marble, Corian™ or other plastic resin products or
sinks made of porcelain and stainless steel should
only be performed by a fabricator installer who is cer
tified for fabricating such materials. Drilling of these
type surfaces by any other means may cause perma
nent, irreparable damage to the countertop surface.
2. If drilling is needed, make the 1-1/4" diameter
hole.
