Filter cartridges to remove (1) sediments, and (2) tastes,
odors and sediments are available for use in the Heavy
Duty Whole House Water Filter. Filter cartridges are not
included with this water filter. Your Sears store has a
selection of the different types of filter cartridges avail-
able.
SEDIMENT FILTER CARTRIDGES
Sediment cartridges remove sand, silt, clay, rust, dirt,
and other sediments from water. For example, a 30
micron cartridge filters larger sediments, and allows
higher flows at less pressure drop. A 5 micron cartridge
filters finer sediments from water, often to a single
faucet.
TASTE & ODOR CARTRIDGES
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.
The 'Ihste and Odor Cartridge available is for taste and
odor reduction, and sediment reduction.
INSTALLATION LOCATION
'lkofilter sediments or tastes and odors from all house
water, locate the Heavy Duty Water Filter on tlle main
water supply pipe (See Figure 1). 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 preceding
filter cartridge information to determine where to locate
the water filter housing. Then, use the drawings on Page
6 as a guide. There are many variables to consider as
you plan. Some of these are:
• The Heavy Duty Water Filter inlet and outlet internal
threads are 1" NPT
• Existing plumbing type (copper, threaded, etc.) and
nominal size (1/2", 3/4", 1" etc.)
• 'lkools you have, and your plumbing skills
• Space available for installing the Heavy Duty Water

A. WATER FILTER ON HOUSE MAIN WATER PIPE, TO FILTER ALL HOUSEHOLD WATER
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: 'Ium 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 fil-
ter, 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.
9. Before turning on the water supply, remove the sump
from the filter head and install the filter cartridge (See
Page 10).

B. WATER FILTER ON HOUSE MAIN WATER PIPE, TO FILTER ALL HOUSEHOLD WATER
USING SOLDERED COPPER FITTINGS (See Figure 4 on Page 6)
MATERIALS AND TOOLS NEEDED:
You will need 2 sweat adaptors, 1" NPT x sweat (sweat
end to fit your main water pipe), lead-free solder and
flux, soldering torch, '[_flon tape, sandpaper or emery
cloth, open end (to fit sweat adaptor) or adjustable jaw
wrench.
INSTALLATION STEPS
CAUTION: Heat created when soldering can damage
the water filter's plastic parts. Be sure to use the follow-
ing procedure to protect the water filter.
1. IMPORTANT: 'Ium off the water supply to the main
pipe. Open a high and low faucet in the water system
to drain the pipe.
2. On the main water pipe, where you will install the fil-
rex, use a tubing cutter to remove a section of pipe
about 12" long. Use sandpaper or emery cloth to thor-
oughly 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 (See
Figure 11).
4. Place, but do not solder, a straight connector onto the
other pipe end (See Figure 11).
5. Remove the sump from the filter head and set the
sump aside.
6. After it cools, apply 4 wraps of Teflon tape to the
threads on the sweat adaptor fitting (See Figure 12).
7. With the IN side of the water filter toward incoming
water, carefully, turn the filter head onto the sweat
adaptor fitting (See Figure 12). Do not cross-thread, or
over-tighten and crack tlle filter head.
8. 'l\ml a sweat adaptor fitting into the other side of the
filter head and hand tighten only. Using a tape meas-
ure or ruler, measure the distance "D" as shown in
Figure 13. Mark this same dimension on a length of
copper 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 4 wraps of Teflon tape to the
threads on the sweat adaptor fitting. Apply flux and
continued
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
