SAFETY GUIDES /SPECIFICATIONS
•Please read this entire manual before
installing and using your undersink water filter
housing. Be sure to follow all guides and rules
carefully. Failure to follow them could cause
personal injury or property damage.
•Check with your local public works
department for plumbing codes. You must
follow their guides as you install the water
filter housing. In Massachusetts, plumbing
codes of Massachusetts shall be adhered to.
Consult with your licensed plumber.
•Use the filter on a potable, safe-to-drink,
home COLD water supply only. The filter
cartridge will not purify water, or make it safe
to drink. DO NOT use on HOT water (100°F,
max.). Do not use with water that is
microbiologically unsafe or of unknown
quality without adequate disinfection before
or after the system. This system is certified for
cyst reduction and may be used on disinfected
waters that may contain filterable cysts.
•Protect the water filter housing and piping
from freezing. Water freezing in the housing
will break it.
•Your undersink water filter housing works
on water pressures of 40 psi (minimum) to 100
psi (maximum). If your house pressure is over
the maximum, install a pressure reducing
valve in the water supply pipe to the water fil-
ter.

variables to consider as you plan. Some of these are:
_" the water filter housing inlet and outlet internal
threads are 3/8" NPT.
_," existing plumbing type (copper, threaded, etc.)
and nominal size (1/4", 3/8" etc.)
_" tools you have, and your plumbing skills
_" cost of materials needed
_" space available for installing the filter housing
Sears has an optional kit available to make installing
the water filter housing easier (see below and page

B. SOLDERED COPPER FITTINGS, FIG. 2
MATERIALS AND TOOLS NEEDED: You will need
2 sweat adaptors, 3/8" NPT x sweat (sweat end to fit
your sink cold water pipe), 4 sweat 90°elbows,
copper pipe, lead-free solder and flux, soldering
torch, Teflon tape, sandpaper or emery-cloth, open
end (to fit sweat adaptor) or adjustable jaw wrench.
CAUTION: Heat created when soldering can dam-
age the water filter housing. Be sure to use the fol-
lowing procedures to protect the water filter.
1. CAUTION: Turn offthe water supply to the sink
cold pipe. Open the sink cold faucet to relieve pres-
sure in the pipe.
Note: If the sink faucet is a single lever, mixing type,
also close the shutoff valve on the hot water side.
2. Use a tubing cutter to remove a section of the sink
cold water pipe (catch trapped water with a rag or
towel). Use sandpaper or emery- cloth to thoroughly
dean and remove all burrs and rough edges from
both pipe ends.
Note: When soldering, use lead-free solder and flux
only. Be sure pipe and fittings are properly cleaned.
Observe caution note above.
3. Refer to FIG. 2, page 5, and to the following draw-
ings. Make typical soldered assemblies A and B as
shown in FIG. 6. After they have cooled, apply Te-
flon tape or pipe joint compound to the pipe threads.
Then turn them into the filter head and tighten.

INSTALLATION STEPS (cont.)
C. THREADED PIPE AND FITTINGS, FIG. 3
MATERIALS AND TOOLS NEEDED: For threaded
pipe instanation you will need pipe wrenches, Teflon
tape or pipe joint compound, a union fitting and pipe
nipples. You may also need a pipe threading tool.
Connect the filter housing as typically shown in FIG.
3, page 5. Observe the following:
• Use Teflon tape or pipe joint compound on all ex-
ternal threads.
• Do not turn pipe or fittings too tightly into the filter
head or you may break it.
•It is important to have some movement in the sink
cold water pipe. This will allow you to tighten the
union fitting, without damaging the filter head, if
pipe lengths are not exact.
•Before turning on the water supply remove the
sump from the filter head and install the filter car-
tridge (see below).
FILTER CARTRIDGE INSTALLATION
TURN TO PAGE 9 AND FOLLOW ALL STEPS UNDER "FILTER CARTRIDGE REPLACEMENT".

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 you first no-
tice the return of the unwanted substance in your
water.
Kenmore Undersink Water Filter Housing model
625.384500 with replacement filter 42-34373 has
been tested and certifiedby NSF International for the
reduction of chlorine, taste and odors. The rated ca-
pacity for this system is 4500 gallons.
Other filter cartridges are available from Sears to re-
move sediments, tastes and odors. Followingis 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-
fine 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.
Taste &Odor Filter Cartridge, Sears Item No.
42-34370: for 95% chlorine reduction,
Sediment Filter Cartridge, Sears Item No. 42-38478
(25 micron): Sediment cartridges remove sand, silt,
day, 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 the sump with water
pressure in the filter.
1. Close the nearest shutoffvalve on the water sup-
ply pipe to the filter. To relieve pressure in the filter,
open the sink cold water faucet.
2. Turn the sump off of the _ter head, to the left or
clockwise. Be careful, the sump is full of water. Do
not lose the large o-ring seal.

Note: A special wrench is available from Sears for re-
moving the sump. See the parts list on page 10.
3. Be sure the inside of the sump is clean. Cleaners are
available from Sears (see the parts list on page 10), or
use hot, soapy water.
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.
5. Lightly lubricate the o- ring seal in the sump with
silicone grease or Vaseline. Be sure it is fully seated
in the 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. Open the sink cold faucet. Then slowly open the
water supply shutoff valve and allow the filter hous-
ing to fill.
9. Close the sink faucet. Then check for leaks between
the sump and the head.
Note: If leaking turn off the water supply and open
the sink cold faucet to depressurize the filter. Then
disassemble the filter and check the o-ring for cuts,
flat spots, etc., and sealing surfaces for foreign mate-
rial. Clean the o-ring and lubricate with silicone
grease or Vaseline. Carefully press into the groove in
the sump.
10. Taste and Odor Cartridges: A taste and odor car-
tridge contains activated carbon, a black powder. Af-
ter the new cartridge is installed open the filtered wa-
ter faucet and allow fine, harmless carbon particles to
purge from the cartridge. Close the faucet when you
no longer see the "fines" in the filtered water, or
approximately 2 - 3 minutes.
