- SAFETY GUIDES -
Read all steps and guides carefully before instal- ling and using your reverse osmosis system. Follow all steps exactly to correctly install. Reading this manual will also help you to get all the benefits from
the reverse osmosis system.
Do not attempt to use this product to make safe drinking water from non-potable water sources. Do not use the system on microbiologically unsafe wa- ter, or water of unknown quality without adequate disinfection before or after the system. This system is certified for cyst reduction and may be used on
disinfected water that may contain filterable cysts.
Check with your local public works department for plumbing and sanitation codes. You must fol-
low their guides as you install the system. Follow your local codes if they differ with guides in this manual. Massachusetts plumbing code 248 CMR shall be adhered to. Please consult your licensed plumber.
This system shall only be used for arsenic reduc- tion on chlorinated water supplies containing de- tectable residual free chlorine at the system inlet.
Water systems using an inline chlorinator should provide a one minute chlorine contact time before the RO system.
This system is acceptable for treatment of influ-
ent concentrations of no more than 27 mg/L nitrate and 3 mg/L nitrite in combination measured as N
and is certified for nitrate/nitrite reduction only for water supplies with a pressure of 280 kPa (40 psig) or greater. This system is supplied with a nitrate/ni-
trite test kit. Product water should be monitored pe- riodically according to the instructions provided
with the test kit.
The reverse osmosis system works on water pres- sures of 40 psi (minimum) to 100 psi (maximum). If your house water pressure is over the maximum, install a pressure reducing valve in the water supply
pipe to the reverse osmosis system.
Do not install the reverse osmosis system out- side, or in extreme hot or cold temperatures. Temper- ature of the water supply to the reverse osmosis sys-
tem must be between 40°F and 100°F. Do not install on hot water.
Read the other limits (pH, hardness, etc.) in the specifications and be sure your water supply con- forms. Also see "Water Supply" on page 4.
The reverse osmosis membrane contains a pre- servative for storage and shipment. Be sure to purge
as instructed on page 11 before using product water.

- 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. 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 KEN- MORE 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 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
Problems, Questions? Call 1-800-426-9345 Kenmore Water Line
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,

- 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 (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 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 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 10, page 10). A typical connec-
tion using the included water supply fitting is shown in Figure 3A below. An optional connection, using stan- dard plumbing fittings (not included), is shown in Figure 3B.
Note: Codes in the state of Massachusetts _vquire installation by a licensed plumbe_, 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
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 mate threads of the water
supply fitting that connect to the cold water pipe.
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" ©D 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.
4. Thread water supply fitting onto pipe and reconnect nut to bottom of fitting.

- 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.
P-trap
Figure 4
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).
0 Use an existing sink top hole for a spray hose or other faucet. A 1-1/4" diameter hole is needed.
J Drill a new hole in the countertop next to the sink. t Drill a new hole in the sink top. CAUTION: Drilling holes into countertops made of

- 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 will 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
membrane sump by twisting 1/4 turn left (_D). Re- move the cartridge from sump. Place the car- tridge in a clean plastic bag.
3. Be sure the o-ring seal is on the sump. Replace the
RO sump by turning to the right (k,) 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
(k_) to lock.
5. Remove the prefilter sump and cartridge. Also
place this cartridge in the clean 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 (k_) to lock.
8. Slowly open the water supply to the RO.
9. Open the faucet by turning knob to the left.
10. Allow water to circulate through the system until you smell the bleach odor at the faucet. Then
close the faucet and allow the to stand idle for 20 minutes.
11. After the 20 minutes open the faucet and run water until the bleach odor is gone.
12. Turn off the water supply to the R©.
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 pmxing instructions: The RO cartridge contains afood _ade preservative that should be rinsed before using water from the system. The preserva-
tive will give product water an unpleasant taste and odor.
4. In 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 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 pref!lter 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. High 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, and the drinking water faucet is 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.
CHECK VALVE
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.
FLOW CONTROL
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 -
RO
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 water supply valve to the RO.

PREFILTER AND POST FILTER CARTRIDGES
You must replace the pref!lter cartridge often to pro- 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 f!lter
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 flom 6.8
to 7.7, the cartridge may last for well over one yea1: How- eve_, 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. 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. Pu_ige the RO membrane cartridge following instruc- tions on page 11.
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.

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.
