SAFETY GUIDES /SPECIFICATIONS

•Please read this entire manual before

installing and using your undersink water filter

housing. Be sure to follow all guides and rules

carefully. Failure to follow them could cause

personal injury or property damage.

•Check with your local public works

department for plumbing codes. You must

follow their guides as you install the water

filter housing. In Massachusetts, plumbing

codes of Massachusetts shall be adhered to.

Consult with your licensed plumber.

•Use the filter on a potable, safe-to-drink,

home COLD water supply only. The filter

cartridge will not purify water, or make it safe

to drink. DO NOT use on HOT water (100°F,

max.). Do not use with water that is

microbiologically unsafe or of unknown

quality without adequate disinfection before

or after the system. This system is certified for

cyst reduction and may be used on disinfected

waters that may contain filterable cysts.

•Protect the water filter housing and piping

from freezing. Water freezing in the housing

will break it.

MATERIALS AND TOOLS NEEDED: You will need

2 sweat adaptors, 3/8" NPT x sweat (sweat end to fit

your sink cold water pipe), 4 sweat 90°elbows,

copper pipe, lead-free solder and flux, soldering

torch, Teflon tape, sandpaper or emery-cloth, open

end (to fit sweat adaptor) or adjustable jaw wrench.

CAUTION: Heat created when soldering can dam-

age the water filter housing. Be sure to use the fol-

lowing procedures to protect the water filter.

1. CAUTION: Turn offthe water supply to the sink

cold pipe. Open the sink cold faucet to relieve pres-

sure in the pipe.

Note: If the sink faucet is a single lever, mixing type,

also close the shutoff valve on the hot water side.

2. Use a tubing cutter to remove a section of the sink

cold water pipe (catch trapped water with a rag or

towel). Use sandpaper or emery- cloth to thoroughly

dean and remove all burrs and rough edges from

both pipe ends.

Note: When soldering, use lead-free solder and flux

only. Be sure pipe and fittings are properly cleaned.

Observe caution note above.

3. Refer to FIG. 2, page 5, and to the following draw-

ings. Make typical soldered assemblies A and B as

shown in FIG. 6. After they have cooled, apply Te-

flon tape or pipe joint compound to the pipe threads.

INSTALLATION STEPS (cont.)

C. THREADED PIPE AND FITTINGS, FIG. 3

MATERIALS AND TOOLS NEEDED: For threaded

pipe instanation you will need pipe wrenches, Teflon

tape or pipe joint compound, a union fitting and pipe

nipples. You may also need a pipe threading tool.

Connect the filter housing as typically shown in FIG.

3, page 5. Observe the following:

• Use Teflon tape or pipe joint compound on all ex-

ternal threads.

• 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 INSTALLATION

TURN TO PAGE 9 AND FOLLOW ALL STEPS UNDER "FILTER CARTRIDGE REPLACEMENT".

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 certifiedby 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. Followingis 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-

fine taste and smell, 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,

day, 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 shutoffvalve 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 _ter 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 fill.

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 Vaseline. 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.
