PLANNING YOUR INSTALLATION
When planning your installation, first read the filter
cartridge information on page 8, and decide where
to locate the water filter housing. Then use the draw-
ings on page 4 to guide you. There are many vari-
ables to consider as you plan. Some of these are:
_" the water filter housing inlet and outlet internal
threads are 3/4" NPT.
_-" existing plumbing type (copper, threaded, etc.)
and nominal size (1/2", 3/4" etc.)
_-" tools you have and your plumbing skills
_" cost of materials needed
_" space available for installing the filter housing
Make a simple sketch of your proposed installation
and a list of plumbing materials you will need. Ob-
tain everything you need before starting the installa-
tion. Be sure you have the tools required.

INSTALLATION STEPS
A. USING COMPRESSION FITTINGS, FIG. 1
1. Apply several wraps of Teflon tape to the threads
of both compression fittings.
2. CAREFULLY, turn the compression fittings into
the water filter head inlet and outlet and tighten. Do
not cross-thread and damage the threads. Do not
overtighten and crack the head.
3. Remove the nut and brass ferrule from both com-
pression fittings and set aside. Using a tape measure
or ruler, measure the distance "D" as shown below.
Mark this dimension below so you do not forget.

8. With the inlet side of the water filter facing in-
coming water, spread the pipes apart and fit both
pipe ends into the compression fittings. Move a fer-
rule and nut up to the fitting. Then turn on and tight-
en the nut. Hold the fitting with one wrench while tight-
ening the nut with the other. Repeat on the other side.
Note: If water flow is from right to left (O O J ), be
sure to turn water filter so inlet isto the right.

Measure to shoulder inside of
fittings. Copper pipe butts
against this shoulder.
4. CAUTION: Turn off the water supply to the
main pipe. Open a high and low faucet in the water
system to drain the pipe.
5. On the main water pipe, where you will install the
filter, mark the dimension "D". You will remove this
section of pipe. Before you begin to cut, double-
check your measurement.
6. Use a tubing cutter to remove the section of pipe.
Remove all burrs and rough edges with the sandpa-
per or emery-cloth.
7. Place a nut and brass ferrule (from compression fit-
tings) onto both pipe ends.

9. Before turning on the water supply remove the
sump from the filter head and install the filter car-
tridge (see page 9).
IMPORTANT: The house cold water pipe is often
used to ground electrical outlets in the home. Ground-
ing protects you from electrical shock. The water fil-
ter housing may have broken this ground. To restore,
buy and install a #4 copper wire across the filter, tight-
ly clamping at both ends as shown here.

B. SOLDERED COPPER FITTINGS, FIG. 2
MATERIALS AND TOOLS NEEDED: You will need
2 sweat adaptors, 3/4" NPT x sweat (sweat end to fit
your main water 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 off the water supply to the
main pipe. Open a high and low faucet, in the water
system, to drain the pipe.

INSTALLATION STEPS (cont.)
2. On the main water pipe where you will install the
filter use a tubing cutter to remove a section of pipe
about 12" long. Use sandpaper or emery-cloth to
thoroughly clean 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.
3. Solder a sweat adaptor onto one of the pipe ends.
4. Place, but do not solder, a straight connector onto
the other pipe end.
sweat adaptor straight connector
5. Remove the sump from the filter head and set the
sump aside.
6. After it cools, apply several wraps of Teflon tape to
the threads on the sweat adaptor fitting.
7. Carefully turn the filter head INLET (if water flow
is from the left) onto the sweat adaptor fitting. If wa-
ter flow is from the right turn the outlet side of the
head onto the fitting. Do not cross-thread or over-
tighten and crack the filter head.

8. Turn a sweat adaptor fitting into the other side of
the filter head and hand tighten only. Using a tape
measure or ruler measure the distance "D" as shown
below. Mark this same dimension on a length of cop-
per pipe. Cut the length of pipe.
9. Remove the sweat adaptor fitting from the filter
head and solder to the cut length of pipe.
10. After it cools, apply several wraps of Teflon tape
to the threads on the sweat adaptor fitting. Apply
flux and place the pipe end of the soldered assembly
into the straight connector. Then turn the adaptor
end into the filter head and tighten.
11. Solder both sides of the straight connector.
12. Before replacing the sump and turning on the
water supply install the filter cartridge (see page 8).
Note: Read the grounding information on page 6,
and comply with the instructions if required to main-
tain continuity.
Co THREADED PIPE AND FITTINGS, FIG. 3
MATERIALS AND TOOLS NEEDED: For threaded
pipe installation you will need a pipe threading tool,
pipe wrenches, pipe joint compound, union fittings
and pipe nipples. Connect the filter housing as typi-
cally shown in FIG. 3, page 4. Observe the follow-
ing:
•Use pipe joint compound on all external threads.
• Do not turn pipe or fittings too tightly into the filter
head or you may break it.
•It is important to have some linear movement in
the house main water pipe. This will allow you to
tighten union fittings without damaging the filter
head if pipe lengths are not exact.
Note: Read the grounding information on page 5,
and comply with the instructions if required to main-
tain continuity.

INSTALLATION STEPS (cont.)
REFER TO PAGE 5. If optional kits are used, follow
instructions included with them.
1. Close the cold water side shutoff valve. (Usually,
there already is a shutoff under the sink. If not, close
the main water shutoff valve near the water meter or
pressure tank.)
2. Cut and remove a section of the cold water pipe.
3. If plumbing with flexible tubing, hang or support
the filter housing in some manner. If using rigid
pipe, be sure to allow a minimum of 1-1 /2" clearance
under the filter for sump removal when changing the
filter cartridge.
4. Use the plumbing procedures on page 5 if using
compression fittings. Follow procedures on pages 5
and 6 for sweat copper and threaded pipe installa-
tion. Be sure water flow is into the filter inlet side
and from the outlet side to the faucet.
Note: A grounding jumper wire is not required.
5. 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. where the water filter is installed (filtering all
house water, or just to one faucet)
2. how much water you use
3. 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-
rice the return of the unwanted substance in your
water or a substantial reduction in flow.
Other filter cartridges are available from Sears to
remove (1) sediments, (2) tastes and odors, (3) tastes,
odors and chemical contaminants, and (4) tastes,
odors and lead.
Many bad tastes and /or odors are removed from wa-
ter by an activated carbon cartridge. It is most often
used to remove chlorine taste and smell, usually to
a single faucet such as the kitchen cold.
(1) Sears Item No. 42-38478 (25 micron), or Item No.
42-38480 (5 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.
The 5 micron cartridge filters finer sediments from
water, usually to a single faucet. Cartridge life, when
filtering water to one faucet, is about 6 months maxi-
mum. Cartridge life is less when filtering all house
water. This time varies depending on the type of sed-
iment cartridge.
When filtering sediments you will know it's time to
replace the cartridge when water pressure drops to
the single faucet, or to the entire house supply.
Filtering water to a single faucet, the filter cartridge
may last for 6 months or more. Cartridge life is less
when filtering all house water. If the cartridge is also
for lead or chemical contaminant removal it is more
important to replace it frequently.
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 has several taste and odor filter cartridges
available. These filters are used to filter the water to
one faucet and are not intended for whole house
filtration. These are:
(2) Sears Item No. 42-34370: for 95% chlorine
reduction,
(3) Sears Item No. 42-34365: for 99% chlorine
reduction, plus chemical contaminants
To filter sediments from all house water, locate the
water filter housing on the main water supply pipe.
Please ask your Sears associate about products that
will remove taste and odors from your water
throughout the home. You can also filter water to
one faucet. For example, install the filter under the
kitchen sink to filter the cold drinking water. Typical-
ly taste and odor flIters are installed to fiIter water to one
faucet only. Refer to the following drawings.

not lose the large o-ring seal.
3. Be sure the inside of the sump is clean. Use warm,
soapy water and rinse well.
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.
9. Close the house faucet. Then check for leaks be-
tween the sump and the head.
Note: If leaking turn off the water supply and depres-
surize the filter. Then disassemble the filter and
check the o-ring for cuts, flat spots, etc., and sealing
surfaces for foreign material. Relubricate the o-ring
with silicone grease or Vaseline and carefully press
into the groove in the sump.

FILTER CARTRIDGE /USEFUL LIFE /REPLACEMENT (cont.)
The adjustable filter wrench provided is intended to
help turn the valve to the "Off", "On" or "Bypass"
positions and remove the sump for easy filter
changes.
Turning the valve - The "push/slide" button on the
wrench will need to be pushed in and the slide
moved up into the wrenching area to fit on the valve.
