INSTALLATION STEPS
STEP 1 - 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 water filter 3/8" tubing. A typical connection using the in-
cluded water supply fitting is shown in FIG.2 -A. 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. Thread water supply fitting onto pipe and reconnect
nut to bottom of 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 cold water pipe to adapt 3/8" OD tubing. A typi-
cal connection is shown in figure 2B. If threaded fit-
tings are used, be sure to use pipe joint compound or
Teflon tape on outside threads,

INSTALLATION STEPS
STEP 4 - MAKE TUBING CONNECTIONS
1. Allowing some slack, measure and cut a length of
3/8" tubing to connect between the supply fitting
and the filter system inlet, FIG. 1. Cut the ends of the
tubing square.
2. Insert tubing all the way into the supply fitting and
inlet elbow fitting. Pull on the tubing to be sure that
it's held firmly in the fitting.
3. Repeat steps I and 2 to connect tubing between the
filter system outlet and the adaptor on the bottom of
the faucet stud, FIG. 1.
TUBING CONNECTION
(all push-in fitting locations)
This system includes push-in fittings for quick tub-
ing connection at most locations. If working with the
fittings do the following.
Connection, FIG. 5:
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 tubing other than supplied with the system is
used, be sure it is of high quality, exact size and
roundness with a smooth surface.
To Disconnect Tubing: Push the collet inward and
hold with a finger while pulling the tubing out.

STEP 5 - FILTER CARTRIDGE INSTALLATION
Turn to page 9 and follow all steps under "Filter Cartridge Replacement".

USING THE SYSTEM
The sink or countertop faucet vends the filtered wa-
ter when opened. It has a hand operated, spring
loaded closed lever to prevent waste. You can also
keep the faucet open by pushing upward on the lever
and locking it against the faucet spout.

FILTER CARTRIDGE /USEFUL LIFE /REPLACEMENT
FILTER CARTRIDGE LIFE
Several variables determine how long a cartridge
will last. These include:
1. how much water you use
2. how much sediment, taste and/or odor, or other
unwanted substance, is in the water
Use the following information as a guide. However,
no matter which type of cartridge you are using, you
will know it is time to replace it when youfirst no-
tice the return of the unwanted substance in your
water.
Kenmore system model 625.384600 with replace-
ment elements 42-34370 and 42-34377 has been
tested and certified by NSF International for the re-
duction of protozoan cysts, lead and chlorine. The
rated capacity for this system is 1000 gallons.
Other filter cartridges are available from Sears to re-
move sediments, tastes and odors, and chemical con-
taminants. Following is a list of filter cartridges
available.
Taste and Odor Cartridges: Many bad tastes and/or
odors are removed from water by an activated car-
bon cartridge. It is most often used to remove chlo-
rine taste and smell, usually to a single faucet such as
the kitchen cold.
Note: Small amounts of hydrogen sulfide (noticeable
as "rotten egg" odor) may be reduced by taste and
odor filters for a short time, quickly exhausting the
carbon media. Consult your Sears store for proper
continuous treatment.
Sears Item No. 42-34362: for sediment removal
Sears Item No. 42- 34365: for 99% chlorine reduction,
plus chemical contaminants
Sediment Filter Cartridge, Sears Item No. 42-34360
(25 micron): Sediment cartridges remove sand, silt,
clay, dirt, and other sediments from water. The 25
micron cartridge filters larger sediments from water,
and allows higher flows at less pressure drop.

FILTER CARTRIDGE REPLACEMENT
CAUTION: Never remove sumps with water pres-
sure in the filter system.
1. Close the water supply shut-off valve (FIG. 1,
page 4) to the filter. Open the filtered water faucet
to relieve pressure in the system.
2. Turn the sump off of the filter head, to the left or
clockwise. Be careful, the sump is full of water. Do
not lose the large o- ring seal.
Note: Aspecial wrench is available from Sears for re-
moving the sump. See the parts list on page 11.

3. Be sure the inside of the sump is clean. Use hot,
soapy water and rinse thoroughly.
4. Remove the wrapper from the new filter cartridge
and insert the filter cartridge in the sump. Some car-
tridges fit either way, while others fit only one way.
Observe markings on the cartridge, or on the wrap-
per.
Note: If you are installing two different types of filter
cartridges, be sure to install in filters I and II as the
guideline on page 3 shows.
5. Lightly lubricate the o-ring seal in the sump with
silicone grease or Vaseline. Be sure it is fully seated
in its groove.
6. Hold the sump up to the filter head aligning the
center hole in the cartridge with the protrusion on the
bottom of the head.
Note: If the sump will not tighten up to the head you
may have the cartridge in upside down. Take the car-
tridge out and check for correct orientation.
7. Being careful not to cross-thread, turn (counter-
clockwise) the sump onto the filter head and tighten
securely.
8. Repeat steps 2 through 7 at the other filter.
9. Open the filtered water faucet. Then, slowly open
the water supply valve and allow the filter housing
to fill.
10. Close the filtered water faucet. Check for leaks be-
tween the sump and the head.
Note: If leaking, turn off the water supply and open
the filtered water faucet to depressurize the filter.
Then disassemble the filter and check the o-ring for
cuts, flat spots, etc., and sealing surfaces for foreign
material. Clean the o- ring and lubricate with silicone
grease or Vaseline. Carefully press into the groove in
the sump.
11. Taste and Odor Cartridges: A taste and odor car-
tridge contains activated carbon, a black powder,
When new, open the filtered water faucet and allow
fine, harmless carbon particles to purge from the car-
tridge. Close the faucet when you no longer see the
"fines" in the filtered water, or approximately 10
minutes.
