INSTALLATION LOCATION
Filtering All House Water
To filter sediments from all house water, locate the Deluxe
Multi-Purpose Water Filter on the main water supply pipe
(See Figure 1). Please ask your Sears associate about
products that will remove taste and odor from your water
throughout your home. You can also filter water to one
faucet. For example, install the filter under the kitchen
sink to filter the cold drinking water (See Figure 2).
PLANNING YOUR INSTALLATION
When planning the installation, first read the "Water
Treatment Filter Cartridges" section on Page 10 to deter-
mine where to locate the water filter housing. Then, use
the drawings on Page 6 as a guide. There are many vari-
ables to consider as you plan. Some of these are:
• The Deluxe Multi-Purpose Water Filter 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
• Space available for installing the Deluxe Multi-Purpose
Water Filter
Make a simple sketch of your proposed installation, and a
list of plumbing materials you will need. Obtain every-
thing you need before starting the installation.

USING COMPRESSION FITTINGS (See Figure 3 on Page 6)
INSTALLATION STEPS
1. Apply 4 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 compres-
sion fittings and set aside. Using a tape measure or
ruler, measure the distance "D" as shown in Figure 7).
Mark this dimension at right so you do not forget.
4. IMPORTANT: 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 sandpaper
or emery cloth.
7. Place a nut and brass ferrule from compression fittings
onto both pipe ends (See Figure 8).
8. With the IN side of the water filter toward incoming
water, spread the pipes apart and fit both pipe ends
into the compression fittings. Move a ferrule and nut
up to the fitting (See Figure 9). Then, turn on and
tighten the nut. Hold the fitting with one wrench while
tightening the nut with the other. Repeat on the other
side.

GROUNDING INFORMATION:
The house cold water pipe is often used to ground electri-
cal outlets in the home. Grounding protects you from
electrical shock. Installing the water filter housing may
have broken this ground. To restore, buy and install a #4
copper wire across the filter, tightly clamped at both
ends, as shown in Figure 10.

C. WATER FILTER ON HOUSE MAIN WATER PIPE, TO FILTER ALL HOUSEHOLD WATER
USING THREADED PIPE & FITTINGS (See Figure 5 on Page 6)
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
typically shown in Figure 5 on Page 6.
D. WATER FILTER UNDERSINI(, TO FILTER WATER TO ONE FAUCET
(See Figure 6 on Page 6)
INSTALLATION NOTES
• 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 7, and
comply with the instructions if required to maintain
continuity.
INSTALLATION STEPS
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 pres-
sure tank.
2. Cut and remove a section of the cold water pipe.
3. If you are plumbing with flexible tubing, hang or sup-
port the filter housing in some manner. If using rigid
pipe, be sure to allow a minimum of 2" clearance
under the filter for sump removal when changing the
filter cartridge.
4. Use the plumbing procedures on Page 7 if using com-
pression fittings. Follow procedures on Page 8 for
sweat copper and threaded pipe installation. Be sure
water flow is to the filter IN side, and from the OUT
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 cartridge (See
Page 11).

Filter cartridges are available from Sears to remove:
• sediments
• tastes and odors
Many bad tastes and/or odors are reduced from water
using an activated carbon cartridge. It is most often used
to remove chlorine taste and odor.
SEDIMENT FILTER CARTRIDGES
Sediment cartridges remove sand, silt, clay, dirt and other
sediments from water.
Sediment Filter Cartridge, 25 Micron: Sears Item No. 42-
38478 (included) filters the larger sediments from water,
and allows higher flows at less pressure drop.
Sediment Filter Cartridge, 5 Micron: Sears Item No. 42-
38478 (optional) filters fine sediments from water, often
to a single faucet.
TASTE & ODOR CARTRIDGES
Sears has several optional 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:
Sears Item No. 42-34370: For reduction of chlorine taste
and odor (one faucet).
Sears Item No. 42-34365: For chlorine reduction, plus
reduction of chemical contaminants (one faucet).
Sears Item No. 42-34373: Premium taste and odor (one
faucet).
Sears Item No. 42-34377: Taste and odor, plus lead
reduction (one faucet).
Several variables determine how long a cartridge will last.
These include:
• How much water you use.
• 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 notice the
return of the unwanted substance in your water. Filter
cartridges are available from your local Sears store and
www.sears.com.
The filter cartridges require replacement 3 or 4 times a
year when used for whole house filtering. Average car-
tridge life when filtering water to one faucet is 6 months
or more. This average time varies depending on the type
of cartridge and water conditions.
SEDIMENT CARTRIDGES: Filtering sediments, you will
know it's time to replace the cartridge when water pres-
sure drops at house faucets.
TASTE & ODOR CARTRIDGES: Filtering taste and odor,
you will know it's time to replace the cartridge when the
taste and odor returns. If the cartridge is also for sedi-
ment removal, you could notice a pressure drop before
the return of taste and odor.
