Water Treatment Filter Cartridges
Filter cartridges to remove (1) sediments, (2) tastes and
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 Taste and Odor Cartridges available are for taste and
odor reduction, and sediment reduction.
odors, and (3) 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 available.
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.
Plan Your Installation
INSTALLATION LOCATION
Filtering All House Water
To filter sediments or tastes and odors from all house
water, locate the Heavy Duty Water Filter on the 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).

GROUNDING INFORMATION:
Ground
Wire
The house cold water pipe is often used to ground elec-
trical 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.

Installation - Type C
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:
INSTALLATION NOTES
For threaded pipe installation, you will need a pipe
threading tool, pipe wrenches, pipe joint compound,
union fittings and pipe nipples. Connect the filter hous-
ing as typically shown in Figure 5 on Page 6.
ꢀ 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 - Type D
D. WATER FILTER UNDERSINK, TO FILTER WATER TO ONE FAUCET
(See Figure 6 on Page 6)
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.
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.
2. Cut and remove a section of the cold water pipe.
NOTE: A grounding jumper wire is not required.
3. If you are plumbing with flexible tubing, hang or sup-
port the filter housing using the included mounting
bracket. If using rigid pipe, be sure to allow a mini-
mum of 2" clearance under the filter for sump removal
when changing the filter cartridge.
5. Before turning on the water supply, remove the sump
from the filter head and install the filter cartridge (See
Page 10).

bottom of the head.
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.
NOTE: If the sump will not tighten up to the head, you
may have the cartridge in upside down or not
centered in the sump. Take the cartridge out and
check for correct orientation.
7. Being careful not to cross-thread, turn the sump to the
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
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
pressure drops at house faucets.
TASTE & ODOR CARTRIDGES: Filtering taste and

when the taste and odor returns. If the cartridge is also
for sediment removal, you could notice a pressure drop
before the return of taste and odor.
right 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. While it is filling, press the filter vent valve
to release air in the filter.
9. Close the sink faucet. Then, check for leaks between
the sump and the head.
NOTE: If a leak is occurring, turn off the water supply
and open the sink cold faucet to depressurize the
filter (or press the vent valve). Then, remove the
sump 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. 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.
When new, open a filtered water faucet and allow
fine carbon particles to purge from the cartridge.
Close the faucet when you no longer see the “fines”
in the filtered water.
