ternal threads.
FILTER CARTRIDGE INSTALLATION
TURN TO PAGE 9 AND FOLLOW ALL STEPS UNDER "FILTER CARTRIDGE REPLACEMENT'
■ Do not turn pipe or fittings too tightly into the filter
head or you may break it.
■ It is important to have some movement in the sink
cold water pipe. This will allow you to tighten the
union fitting, without damaging the filter head, if
pipe lengths are not exact.
■ Before turning on the water supply remove the
sump from the filter head and install the filter car
tridge {see below).
FILTER CARTRIDGE / USEFUL LIFE / REPLACEMENT
FILTER CARTRIDGE LIFE
Several variables determine how long a cartridge
will 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 Undersink Water Filter Housing model
625.384500 with replacement filter 42-34373 has
been tested and certified by NSF International for the
reduction of chlorine, taste and odors. The rated ca
pacity for this system is 4500 gallons.
Other filter cartridges are available from Sears to re
move sediments, tastes and odors. 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.
Taste & Odor Filter Cartridge, Sears Item No.
42-34370: for 95% chlorine reduction.
Sediment Filter Cartridge, Sears Item No. 42-38478
(25 micron): Sediment cartridges remove sand, silt,
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 the sump with water
pressure in the filter.
1. Close the nearest shutoff valve on the water sup
ply pipe to the filter. To relieve pressure in the filter,
open the sink cold water faucet.
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.
Note; A special wrench is available from Sears for re
moving the sump. See the parts list on page 10,
3. Be sure the inside of the sump is clean. Cleaners are
available from Sears (see the parts list on page 10), or
use hot, soapy water.
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.
5. Lightly lubricate the o-ring seal in the sump with
silicone grease or Vaseline. Be sure it is fully seated
in the 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. Open the sink cold faucet. Then slowly open the
water supply shutoff valve and allow the filter hous
ing to fiU,
9. Close the sink faucet. Then check for leaks between
the sump and the head.
Note: If leaking turn off the water supply and open
the sink cold faucet to depressurize the filter. Then
disassemble the filter and check the o-ring for cuts,
flat spots, etc., and sealing surfaces for foreign mate
rial. Clean the o-ring and lubricate "with silicone
grease or VaseUne. 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. Af
ter the new cartridge is installed open the filtered wa
ter faucet and allow fine, harmless carbon particles to
purge from the cartridge. Close the faucet when you
no longer see the "fines" in the filtered water, or
approximately 2-3 minutes.
