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  
odor, you will know it's time to replace the cartridge  
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.  
FILTER CARTRIDGE INSTALLATION/  
REPLACEMENT  
11. Retighten the sump 7 days after replacing filter.  
CAUTION: Never remove the sump with water pressure  
in the filter.  
Vent Valve  
1. Close the nearest shutoff valve on the water supply  
pipe to the filter. To relieve pressure in the filter, press  
the vent valve on top of the filter head (See Figure 14)  
or open a cold water faucet after the filter. Some water  
may leak out of the vent valve as pressure is being  
relieved.
