STEF 5 - FILTER CARTRIDGE INSTALLATION
Turn to page 9 and follow all steps under "Filter Cartridge Replacement".
CAUTION
USING THE SYSTEM
The sink or countertop faucet vends the filtered wa
ter when opened. It has a hand operated, spring
loaded closed lever to prevent waste. You can also
keep the faucet open by pushing upward on the lever
and locking it against the faucet spout.
FILTER CARTRIDGE / USEFUL LIFE / REPLACEMENT
FILTER CARTRIDGE LIFE
Several variables determine how long a cartridge
win last. These include:
1. how much water you use
2. 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 no
tice the return of the unwanted substance in your
water.
Kenmore system model 625.384600 with replace
ment elements 42-34370 and 42-34377 has been
tested and certified by NSF International for the re
duction of protozoan cysts, lead and chlorine. The
rated capacity for this system is 1000 gallons.
Other filter cartridges are available from Sears to re
move sediments, tastes and odors, and chemical con
taminants. Following is a list of filter cartridges
available.
Taste and Odor Cartridges: Many bad tastes and/or
odors are removed from water by an activated car
bon cartridge. It is most often used to remove chlo
rine taste and smeU, usually to a single faucet such as
the kitchen cold.
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
carbon media. Consult your Sears store for proper
continuous treatment.
Sears Item No. 42-34362: for sediment removal,
Sears Item No. 42- 34365: for 99% chlorine reduction,
(25 micron): Sediment cartridges remove sand, sût,
clay, dirt, and other sediments from water. The 25
micron cartridge filters larger sediments from water,
and allows higher flows at less pressure drop.
FILTER CARTRIDGE REPLACEMENT
CAUTION: Never remove sumps with water pres
sure in the filter system,
1. Close the water supply shut-off valve (FIG. 1,
page 4) to the filter. Open the filtered water faucet
to relieve pressure in the system.

4. Remove the wrapper from the new filter cartridge
and insert the filter cartridge in the sump. Some car
tridges fit either way, while others fit only one way.
Observe markings on the cartridge, or on the wrap
per.
Note: If you are instalUng two different types of filter
cartridges, be sure to install in filters I and II as the
guidehne 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 its groove.
6. Hold the sump up to the filter head aligning the
center hole in the cartridge with the protrusion on the
bottom of the head.
Note: If the sump will not tighten up to the head you
may have the cartridge in upside down. Take the car
tridge out and check for correct orientation.
7. Being careful not to cross-thread, turn (counter
clockwise) the sump onto the filter head and tighten
securely.
8. Repeat steps 2 through 7 at the other filter.
9. Open the filtered water faucet. Then, slowly open
the water supply valve and allow the filter housing
tofiU.
10. Close the filtered water faucet. Check for leaks be
tween the sump and the head.
Note: If leaking, turn off the water supply and open
the filtered water faucet to depressurize 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 lubricate with silicone
grease or Vaseline. Carefully press into the groove in
the sump.
11. Taste and Odor Cartridges: A taste and odor car
tridge contains activated carbon, a black powder.
When new, open the filtered water faucet and allow
fine, harmless carbon particles to purge from the car
tridge, Close the faucet when you no longer see the
"fines" in the filtered water, or approximately 10
minutes.
