WATER TREATMENT FILTER CARTRIDGES
Filter cartridges are available (not included with drinkĆ
You can customize your filter system to the specific
treatment needs of your water supply. Use the same
type of filter cartridge in both Filter I and Filter II to
maximize treatment for a specific water problem. Or,
use any combination of cartridges to treat more than
one problem. When using 2 different cartridges, place
in Filter I and Filter II as follows for maximum affect.

ments, tastes and odors, tastes, odors and chemical
contaminants, and tastes, odors and lead.
Following is a list of filter cartridges available at the
time of this printing. Shop your local Sears store for
the current selection.
GUIDELINE FOR CARTRIDGE PLACEMENT
(1) Sediment Filter Cartridge, Sears Item No.
42-34360 (25 micron), or (2) Item No. 42-34362
(5 micron): Sediment cartridges remove sand, silt,
clay, dirt, and other sediments from water. The 25 miĆ
cron cartridge filters larger sediments from water, and
allows higher flows at less pressure drop. The 5 miĆ
cron cartridge filters finer sediments from water.
When using 2 different cartridges, of the 6 depicted below,
always place the lowest numbered cartridge in Filter I, and
the highest numbered in Filter II. For example, if you select
a 5 micron sediment cartridge (2), and a taste & odor plus
lead cartridge (5), the sediment cartridge goes into Filter I.

Note: The numbers (5) and (6) cartridges above both
have built-in restrictors to control water flow rate for
maximum filtering. You will notice reduced flow from
the faucet when using either or both cartridges.
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 carĆ
bon media. Consult your Sears store for proper continĆ
uous treatment.
Locate the water filter housing on the cold water supĆ
ply pipe, under the kitchen and/or bathroom sink, to
filter the cold drinking water. Refer to the following
drawing.
Sears has several taste and odor filter cartridges availĆ
able. These are:

INSTALLATION STEPS
4. Place clamp A and B around the pipe and secure
in place with 2 screws. Tighten both screws evenly,
but do not overtighten and crush the pipe.
STEP 1 - WATER SU PPLYSADDLE VALVE
Check and comply with local plumbing codes before
you install a cold water supply fitting. The special self-
tapping (into copper) saddle valve included installs as
follows. Locate the valve on the cold water pipe to the
kitchen sink, as shown in FIG. 1.
5. Carefully turn the handle all the way inward to
pierce a hole in the copper or plastic pipe.
6. Put a few wraps of Teflon tape on the valve body
threads. Then, with the washer in place, turn the tubĆ
ing adaptor onto the valve and tighten securely.
Note: This valve has a cutting pin and it will pierce a
hole in copper tubing or plastic pipe. Ifinstalling on
iron pipe, you have to drill a 1/8" hole for the piercing
pin (read danger note below).
Note: Be sure the valve packing nut is tightened. Do
not turn on the water supply at this time.
FIG. 2
DANGER (IF DRILLING METAL PIPE): To protect
yourselfrfom serious injury or fatal shock, use a
battery powered hand drill only to make the hole. Do
not use an electric drill.

Select 1 of the following places to install the faucet. Be
sure there's room underneath so you can make the
needed connections. Ifyou are installing the deluxe
model, be sure the electronic indicator base will fit flat
against the surface.

CAUTION: Never remove sumps with water presĆ
sure in the filter system.
2. Turn the sump off of the filter head, to the left or
clockwise. Be careful, the sump is full of water. Do not
lose the large o-ring seal.
1. Closethewater supply saddlevalve(FIG. 1 and
2) to the filter. Press the vent valve on the top of
the head to relieve pressure in the system, FIG. 5,
or open the filtered water faucet.
Note: A special wrench is available from Sears for reĆ
moving the sump. See the parts list on page 11.

3. Be sure the inside ofthe sump is clean. Cleaners are
available from Sears (see the parts list on page 11), or
use hot, soapy water.
9. Open the filtered water faucet. Then, slowly open
the water supply saddle valve and allow the filter
housing to fill. While it is filling, press the filter vent
valve to release air in the filter.
4. Remove the wrapper from the new filter cartridge
and insert the filter cartridge in the sump. Some carĆ
tridges fit either way, while others fit only one way.
Observe markings on the cartridge, or on the wrapper.
10. Close the filtered water faucet. Then, check for
leaks between the sump and the head.
Note: If leaking, turn off the water supply and open
the filtered water faucet, or press the vent valve, to deĆ
pressurize the filter Then, disassemble the filter and
check the o-ring for cuts, flat spots, etc., and sealing
surfaces for foreign material. Clean the o-ring and luĆ
bricate with silicone grease or Vaseline. Carefully
press into the groove in the sump.
Note: If you are installing 2 different types of filter carĆ
tridges, be sure to install in filters I and II as the guideĆ
line on page 3 shows.
5. Lightly lubricate the o-ring seal, in the sump, with
silicone grease or Vaseline. Be sure it is fully seated in
it's groove.
11. On deluxe models with the electronic base, reĆ
move and install 2 new AA alkaline batteries in the batĆ
tery pack. Removing the batteries, or momentarily disĆ
connecting the leadwires, resets the 6 month
electronic base timer.
6. Hold the sump up to the filter head, aligning the
center hole in the cartridge with the protrusion on the
bottom ofthe head.
Note: Ifthe sump will not tighten up to the head, you
may have the cartridge in upside down. Take the carĆ
tridge out and check for correct orientation.
12. Tasteand Odor Cartridges: A taste and odor carĆ
tridge contains activated carbon, a black powder.
When new, open the filtered water faucet and allow
fine, harmless carbon particles to purge from the carĆ
tridge. Close the faucet when you no longer see the
``fines'' in the filtered water.
7. Being careful not to cross-thread, turn (counterĆ
clockwise) the sump onto the filter head and tighten
securely.
8. Repeat steps 2 through 7 at the other filter.
