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 18.
Check Your Water Supply: The cold water supply to
the RO system must be within certain quality limits.
See the specification table on page 18. 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 15.
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 19).
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 19. A
sink p-trap drain adaptor is included to install where
codes permit, as an optional drain point (page 6).

- STEP 2: INSTALL DRAIN ADAPTER -
■ Note: Running the drain tubing directly to a floor
drain, sump, standpipe, laundry tub, etc., as shown
on page 19, 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 10, page 10).
^ 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.

- STEP 6: SANITIZING, PRESSURE TESTING & PURGING
SANITIZING
Sanitizing is recommended upon installation of the
RO system, and after servicing inner parts. It is im
portant for the service person to have clean hands
while handling inner parts of the system.
CA UTION: Be sure to remove the RO membrane and
both filter cartridges as follows, before sanitizing.
Chlorine ivill destroy the RO membrane cartridge.
1. Be sure the water supply to the RO is turned off,
and the RO faucet is open to relieve pressure.
2. Referring to Figure 12, page 14, remove the RO
membrane sump by twisting 1/4 turn left (^J). Re
move the RO cartridge from sump. Place the car
tridge in a

RO sump by turning to the right (C,) to lock.
4. Remove the postfilter sump, turning to the left.
Take the cartridge from the sump and place in the
plastic bag. Replace the sump by turning to the right
(t^) to lock.
5. Remove the prefilter sump and cartridge. Also
place this cartridge in the clean bag.
clean plastic bag.
6. If needed to clean, flush the prefilter sump with
fresh water. Then fill with water to about 1" from the
top. Add 1.0 ounce of chlorine (ordinary 5.25%
household bleach...Hilex, Clorox, etc.) and mix in the
water. Do not add chlorine first. Concentrated it will
attack plastics.
7. Carefully replace the sump on the prefilter head
and turn to the right (C,) to lock.
8. Slowly open the water supply to the RO.
9. Open the RO faucet by turning knob to the left.
10. Allow water to circulate through the RO system
until you smell the bleach odor at the faucet. Then
close the faucet and allow the RO to stand idle for 20
minutes.
11. After the 20 minutes open the RO faucet and run
water until the bleach odor is gone.
12. Turn off the water supply to the RO.
13. Be sure your hands are clean. Then, repeat steps
1-5 and 7, only replace all cartridges.
Important: Refer to Figure 12, page 14, and to page 15
when replacing cartridges. The prefilter (left side)
cartridge and the postfilter (right side) have puple
end caps.
PRESSURE TESTING
1. Do the preceding sanitizing procedures before
pressure testing.
2. Open the water supply shutoff valve to the RO.
3. Open the main water supply valve and several
house faucets to purge air from the system. Close
faucets when water runs smooth.
PURGING RO MEMBRANE
Important purging instructions: The RO cartridge
contains a food grade preservative that should be rinsed
before using water from the system. The preserva
tive will give product water an unpleasant taste and
odor.
4. hi about 2 hours, pressure will start to build in the
RO system. Then, carefully check all fittings and con
nections for water leaks. Correct leaks if any are
found.
Note: When the system is first pressurized, water
may "spurt" from the faucet airgap hole until air is
expelled from the RO system.
1. Allow the storage tank to fill for about 4 hours.
Then open the RO faucet until the tank is empty and
flow stops. Close the RO faucet.
2. Repeat step 1 five more times (for a total of 6) to
purge the RO system. Then the RO system is ready
to make product water for use.

- HOW YOUR REVERSE OSMOSIS SYSTEM WORKS
PREFILTER
Water from the cold supply pipe enters the RO as
sembly prefilter first (Figure 10, page 10, and sche
matic, page 13).
The prefilter has a replaceable sediment cartridge
with activated carbon in its composition. The car
tridge (10 micron) removes sand, silt, dirt, other sedi
ments, and up to the ppm of chlorine shown in the
specifications from the feed water (page 18). Chlo
rine will destroy the RO membrane. Filtered, clean,
chlorine- free water flows from the prefilter, to the RO
membrane cartridge.
IMPORTANT: See prefilter maintenance, page 14.
REVERSE OSMOSIS (RO) CARTRIDGE
The RO cartridge is a tightly wound special mem
brane. The membrane removes the dissolved solids
and organic matter when water is forced through the
cartridge. Fligh quality product water (about one
ounce per minute) exits the RO cartridge and goes to
the storage tank, or to the postfilter and RO faucet.
Reject water, with the dissolved solids and organic
matter, is routed through the flow control and to the
drain.
STORAGE TANK
The storage tank holds up to 2.3 gallons of product
water. A diaphragm inside the tank keeps water
pressurized to about 30 psi, when the tank is full, to
provide fast flow to the RO faucet. The tank, when
empty, is pressurized to 5 - 7 psi.
POST FILTER
After leaving the storage tank, but before going to the
RO faucet, product water goes through the post filter.
The post filter is an activated carbon type filter. Any
remaining tastes and odors are removed from the
product water. Taste-free, odor-free, clean, high
quality drinking water is available for use.
FAUCET
The sink or countertop faucet has a hand operated
knob to access drinking water. An air-gap is built
into the faucet drain water connection to comply
with plumbing codes.
FAUCET ELECTRONICS (UltraFilter 350)
The RO system will monitor the length of time the fil
ters have been installed. The faucet has an indicator
light that flashes to inform you of the status of the fil
ters.
Green - Filters are good. Red - Filters need to be re
placed after 6 months of time has passed.
SHUTOFF ASSEMBLY
To conserve water, the drinking water system has an
automatic shutoff system. When the storage tank has
filled to capacity,
closed, pressure closes the shutoff to stop flow to
drain. Pressure in the storage tank is about half of the
water supply pressure. After drinking water is used,
and pressure in the system drops, the shutoff opens
to allow water flow again.
A check valve (Figure 16) is located in the RO man
ifold, above the center sump. The check valve pre
vents a backward flow of product water from the
storage tank. A backward flow could rupture the RO
membrane.
Water flow through the RO membrane is regulated
by the flow control. It maintains the desired flow rate
to obtain the highest quality drinking water. The
flow control is located in the end of the 1 / 4" red drain
tubing, at the RO manifold drain port.

- CARE OF YOUR REVERSE OSMOSIS SYSTEM
To keep your reverse osmosis system operating and
producing high quality water, you must make sure
supply water is always within the limits shown in the
specifications. Good supply water (soft water is rec
ommended) helps to assure longer life from the RO
membrane cartridge, prefilter and postfilter car
tridges. However, each of these will wear out in time
and need replacement.
This reverse osmosis system contains a replace
able treatment component critical for effective
removal of total dissolved solids. The monitor
faucet feature provides continuous analysis of the
systems performance. For systems not equipped
with the monitor faucet function, it is highly
recommended that you have your water tested at
least every 6 months to verify your system is
performing properly. Test kits are available by
calling 1-800-826-8553 ext. 47, or check the water
testing section of your local phone directory.
If the RO assembly is wall mounted, you may be able
to replace parts with the assembly left on the wall. If
not, simply lift the RO assembly from the mounting
washers and lay on the cabinet floor when replacing
the prefilter and post filter cartridges and RO mem
brane.
Note: To prevent spillage, place a container under the
RO assembly, or put the RO assembly in a container
to catch the water.
CAUTION; Before disconnecting parts, be sure to
close the ivater supply valve to the RO.

tect the RO membrane from being destroyed by chlorine,
and/or from plugging with sediments in your water
supply. If the water supply contains both chlorine
and sediments, replace the prefilter cartridge at least
every 6 months of product water use. Replace more
often than 6 months if it begins to plug with sedi
ments.
If the water has sediments only, with no chlorine, you
may notice a slower making of product water as the
prefilter collects the sediments. When this occurs, re
place the prefilter cartridge. Also replace the post filter
cartridge.
To replace the filter cartridges (see Figure 12):
1. Turn off the water supply and open the RO faucet
to relieve pressure.
2. Remove (turn to the left) both sumps from the filter
heads. Be careful.. .the sumps are full of water.
3. Remove and discard the inner cartridges in a prop
er manner. Flush the insides of the sumps with fresh
water.
Do not lose the large o-ring seals.
4. Insert new cartridges with o-ring*^ seals towards
the top, and with lubricated* o- rings in place, turn to
the right to reattach the sumps.
5. Remove and replace batteries to reset counter and
timer, (monitor models).
*Note: Use a lubricant approved for use on a potable
water supply.

RO MEMBRANE CARTRIDGE
The life of the RO membrane cartridge depends
mostly on the pH of the supply water to the RO sys
tem (see specifications). Cartridge life is shorter with
higher pH. For example, if supply water pH is from 6.8
to 7.7, the cartridge may last for well over one year: Hoioever, cartridge life may be as short as 6 months if the pH
is as high as 8.5 to 10. Higher pH weakens the cartridge
membrane and causes pin-hole leaks.
It's time to replace the RO cartridge when the pro
duction rate and/or quality of product water drops.
Product water may begin to taste different or bad, in
dicating solids and organics are passing through the
RO membrane. To be sure it is the RO cartridge, re
place the prefilter and postfilter cartridges first.
To replace the RO cartridge (see Figure 12):
1. Turn off the water supply and open the RO faucet
to relieve pressure.
2. Remove (turn to the left) the sump from the filter
head. Be careful. . .the sump is full of water.
3. Remove and discard the RO cartridge in a proper
manner. Flush the insides of the sump with fresh wa
ter. Do not lose the large o-ring seals.
FLOW CONTROL
The flow control is vital for proper operation of the
RO membrane cartridge. The control keeps water
flow through the membrane at the needed rate to ob
tain the best quality product water.
Periodically check the flow control to be sure the
small hole through it is clean and unrestricted.
Note: Sanitizing is recommended after servicing in
ner parts of the system (see page 11).
4. Insert new RO cartridges with o-ring seals to
wards the top, and with lubricated o-ring in place,
turn to the right to reattach the sump.
5. Remove and replace batteries to reset counter and
timer, (monitor models).
6. Purge the RO membrane cartridge follaiuing instruc
tions on page 11.

TUBING CONNECTION
(all push- in fitting locations)
This RO system includes push- in fittings for quick
tubing connection at most locations. If working with
the fittings, do the following.
Connection (Figure 14):
1. Use a sharp cutter or knife to cut the end of tubing
square.
2. Inspect the end (about 1") of the tubing to be sure
there are no nicks, scratches or other rough spots. If
needed, cut the tubing again.
3. Push tubing through the collet and all the way into
fitting. Full engagement is 11/16" for 1/4" tubing,
and 3 / 4" for 3 / 8" tubing.
If using tubing other than tubing supplied with the
system, be sure it is of high quality, exact size and
roundness with a smooth surface.

1. AT LEAST every 6 months, replace the prefilter and postfilter cartridges or when red LED flashes,
2. Replace the RO membrane cartridge when the percent rejection of total dissolved solids (TDS) is less than shown
in the specifications (see B, below).
3. Replace the battery once per year.
If any of the following occur before the 6 months, replace as directed.
A. Slow Making of Product Water: Replace the prefilter cartridge.
If the production rate does not improve, replace the post filter car
tridge and RO membrane cartridge.
B. High Total Dissolved Solids (TDS) in Product Water: You can
get a free TDS test through some Sears retail stores or service
departments. If the store or service department does not have a
TDS meter, you can send treated and untreated water samples to
a water analysis lab for testing. It Is important to test both the
treated and untreated water to determine system performance. If
the TDS is not within the system’s performance guidelines,
replace the prefilter, post filter and RO membrane cartridges.

- REMOTE INSTALLATION LOCATIONS -
Possible remote locations for the RO nearby the
kitchen or bathroom sink include; (1) a basement area
underneath the sink, and (2) an adjacent room or
closet. Longer lengths of tubing (see parts list on
page 20) may be needed.
You can run the drain tubing directly to one of several
suitable open drain points, as shown below, bypas
sing the faucet airgap and p-trap drain. This type of
drain is the preferred over the p-trap drain adapter.
Check your local codes. Always be sure to provide an
air gap between the end of the hose and the drain
point.
