install a cold water supply fitting. The fitting must provide a leak-tight connection to the water filter 1/4" tubing, if
additional tubing is required, see parts list at the end of this manual. A typical connection using the included water
supply fitting is shown in Figure 2-A. An optional connection using standard plumbing fittings (not included) is
shown in Figure 2-B. in Massachusetts, plumbing codes of Massachusetts shall be adhered to. Consult with a
licensed plumber
A. WATER SUPPLY FITTING (included)
1. Shut off the water supply and open faucets to drain
water from the sink cold water pipe.
2. Loosen nut that connects the cold water faucet to cold
water plumbing.
3. Thread water supply fitting onto pipe and reconnect
nut to bottom of fitting. Be sure to use a light coating
of pipe joint compound or Teflon tape (included) on
outside threads. Care should be taken to prevent
cross-threading the plastic fitting.
B. OPTIONAL PIPE FITTINGS
(compression type shown)
1. Shut off the water supply and open faucets to drain
water from the sink cold water pipe.
2. Complying with plumbing codes, install a fitting on
the cold water pipe to adapt 1/4" OD tubing. A typical
connection is shown in Figure 2-B. If threaded fittings
are used, be sure to use pipe joint compound or Teflon
tape on outside threads.

Select one of the following options to install the faucet.
Be sure there is room underneath to make the needed
connections.
o Use an existing sink top hole for spray hose or
soap dispenser.
o Drill a new hole in the sink top.
• Drill a hole in the countertop next to the sink.
CAUTION: Drilling holes into countertops made of
stone or solid surface materials such as granite, marble,
Corian rMor other plastic resin products should only be
performed by a qualified installer. Drilling these types
of surfaces by any other means may cause permanent,
irreparable damage to the countertop surface.
1. if drilling is needed, make a 3/4" dia. (minimum) hole
for the faucet.
2. Place plumbers' putty around the drilled hole to pre-
vent water leaks around the faucet.

NOT TO CROSS-THREAD OR OVERTIGHTEN.
3. if the faucet is not assembled, slide the lever over the
cylindrical nut. Wet the o-ring seals on the faucet
spout. Remove and discard the short piece of tubing
from the faucet body and insert the spout in its place.
4. Connect tubing to faucet as described on page 7.
5. Lower the faucet into the sink or countertop hole.
6. On the underside of the sink or countertop, insert the
large steel washer between the mounting hole and the
spacer on the faucet stud (see assembled view). Then
turn the hex nut up to the spacer and tighten. Tighten
the hex nut so the faucet cannot move, but do not
overtighten.

This system includes push-to-connect fittings for quick
tubing connections at most locations. To make tubing
connections with the fittings, do the following:
1. Allowing some slack, measure and cut a length of 1/4"
tubing to connect between the supply fitting and the
filter system inlet (See Figure 1). Use a sharp cutter or
knife to cut the end of tubing square.
2. inspect the tubing, about 1" from end, to be sure there
are no nicks, scratches or other rough spots, if needed
cut the tubing again.
3. Push tubing through the collet and all the way into fit-
ting. Full engagement is 11/16" for 1/4" tubing. Pull
on the tubing to be sure that it is held firmly in the fit-
ting.
if more tubing is required, see parts list at the end of this
manual.

CAUTION: Never remove the sump with water
pressure in the filter.
1. Close the nearest shutoff valve on the water supply to
the filter. To relieve pressure in the filter, open the fil-
tered water faucet.
2. Turn the sump off of the filter head, to the left. Be
careful, as the sump is full of water. Do not lose the
large o-ring seal.
NOTE: A special wrench is included for removing the
sump. See the parts list on page 10. Use only the
included wrench on the sump (or loosen and tighten the
sump by hand).
3. if replacing the filter cartridge, remove used cartridge
from sump and use warm, soapy water to clean sump.
4. Remove the wrapper from the new filter cartridge
and, with clean or gloved hands, insert the filter car-
tridge into the sump. Some cartridges fit turned either
way, while others fit only one way: Check the car-
tridge to see if orientation is indicated.
5. When changing filter, lightly lubricate the o-ring seal
in the sump with silicone grease. Be sure the o-ring is
fully seated in the groove.
6. Hold the sump up to the filter head, and align the cen-
ter hole in the cartridge with the protrusion on the
bottom of the head.
NOTE: if the sump will not tighten up to the head by
hand, you may have the cartridge in upside down or
misaligned. Take the cartridge out and check for correct
orientation.
7. Being careful not to overtighten or cross-thread, turn
the sump to the right onto the filter head and tighten
securely by hand. Make sure to check for leaks, as
described below.
8. Open the filtered water faucet. Slowly open the water
supply shutoff valve and allow the filter housing to
fill. Close the filtered water faucet.

9. Check for leaks between the sump and the head.
Leaks may not be immediately visible. Check periodi-
cally for the next 24 hours.
NOTE: If a leak occurs, turn off the water supply and
open the filtered water faucet to depressurize the filter.
Disassemble the filter and check the o-ring and sealing
surface for cuts, flat spots, or foreign material. Clean the
o-ring and lubricate with silicone grease. Carefully press
o-ring into the groove in the sump.
10. if using a Taste and Odor Cartridge: A taste and
odor cartridge contains activated carbon, a black
powder. After the new cartridge is installed, open
the filtered water faucet and allow carbon particles to
purge from the cartridge. Close the faucet when you
no longer see "fines" (discoloration) in the filtered
water, or after approximately 2 - 3 minutes.

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. No matter
which type of filter cartridge you are using, it may be
time to change the cartridge:
V When you first notice the return of the unwanted sub-
stance (sediment, taste and odor) in your water.
Y When you notice a decrease in water flow from the
filtered water faucet.
Y When six months have elapsed.
Kenmore Undersink Water Filter Housing System model
625.384540 with replacement filter 42-34373 has been
tested and certified by NSF International for the reduc-
tion of chlorine, taste and odors. The rated capacity for
this system is 4500 gallons.
Other filter cartridges are available from Sears to remove
sediments, tastes and odors. Consult your Sears store.
Taste and Odor Cartridges: Many bad tastes and/or
odors are removed from water by an activated carbon
cartridge, it is most often used to remove chlorine taste
and smell.
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.
