commonthread on kitchen faucets) cold water line.
• Please read all instructions and precautions before installing and
using your ltration system.
• Numbered diagrams correspond with numbered steps.
1. Installing the Water Supply Adapter
The supply adapter ts 1/2"-14NPS supply threads. If local codes
permit, it may be used to connect the US-1000to the cold water supply
line. If local codes donot permit the use of the supply adapter, alternate
connectors can be obtainedfrom your local supplier.
A. Turn o cold water supply line. If cold water line does not have a
shut-ovalve under the sink, you should install one.
B. Turnon the cold water faucet andallow all water to drain from line.
C. Disconnect cold water line from 1/2"-14NPS threaded stub on
bottomof main faucet.
D. Applyplumber tape onto threads of faucet stub and supply adapter.
Screw the water supply adapter to the threaded faucet stub as
shown.
E. Using the nut that previouslyconnected the cold water line to the
faucet, screw the coldwater line to the male supply adapter threads.
2. Selecting the Faucet Location
NOTE: The drinking water faucet should be positionedwith function,
convenience, andappearance in mind. Anadequate flat area is
required to allow faucet base to rest securely. The faucet fits
througha 3/4"hole. Mostsinks have pre-drilled 13⁄8" or 11⁄2"
diameter holes thatmaybe used for faucetinstallation. If these
pre-drilled holes cannot be usedor are in an inconvenient
location, it will be necessary to drill a 3/4"hole inthe sinkto
accommodate the faucet.
CAUTION:Thisprocedure may generate dusts which can cause severe
irritation if inhaled or come in contactwith the eyes. The
use ofsafety glasses andrespirator for this procedure is
recommended.
CAUTION:DONOTATTEMPT TODRILL THROUGHAN ALL-PORCELAIN
SINK. If youhave an all-porcelain sink, mountthe faucet in
pre-drilled sprayer hole or drill throughcountertopnext to
sink.
CAUTION:When drilling througha countertop make sure the area
below the drilled area is free of wiringandpiping. Make
certain that youhave ample roomto makethe proper
connections to the bottomof the faucet.
CAUTION:Donot drill through a countertop that is more than 1" thick.
CAUTION:Donot attempt to drill througha tiled, marble, granite or
similar countertop. Consulta plumber or the countertop
manufacturer for adviceor assistance.
(A) Line bottomof sink with newspaper to prevent metal shavings, parts,
or tools from falling down drain.
(B) Place masking tape over the area tobe drilled to prevent scratches if
drill bit slips.
(C) Mark hole with center punch. Use a 1/4"drill bit for a pilothole, then,
using a 3/4"drill bit or hole saw, drill a hole completely throughthe

(B) Install mountingscrews at least 133⁄4" (350mm) from cabinet oor and
41⁄8" (124mm) apart. Leave enough space (approximately 1/2"[13 mm])
between the head ofthe screw and the wall to slip system ontoscrews.
(C) Place system overscrews on wall and slide downwardsto lock into place.
Make certain system is rmly attached to wall to prevent it from falling
and possibly being damaged.
5. Connectingthe Faucet
(A) Insert one end of the 1/4"tube, supplied in the installation kit, into the
gray quick-connecttting collar located on the bottomof the threaded
shaft of the faucet. Push tubing into the tting until youcome to a hard
stop.
CAUTION:Donot bend or crimp tube when inserting.
(B) Gently pull back onthe tube to ensure it is connected properly.If the tube
comes out of tting, cut a small section of the tube oand reconnect.
6. Connectingthe SupplyAdapter andInlet ofFilter
(A) Determine the length of plastic tubing needed to connect the inlet (left)
side of the lter with the supplyadapter. Be sure to allow enoughtubing
to prevent kinkingand cut the tubingsquarely. Place a mark 5/8"from the
end of the tubing.
(B) Wet tubingwith water and insert into supplyadapter 5/8"until mark is
ush with tting.
NOTE: Disconnecting the Tubingfrom the Quick-ConnectFittings:
Routine maintenance andcartridge replacement will not require
that youdisconnect the tubing from the lter system; however,
tubing may be quickly and easily removed from the tting if
necessary. First, turn othe water supply to the lter. Openfaucet,
then press in the grey collar aroundthe tting while pulling the

7. Connectingthe System
(A) Assemble tubing with system as shown in Fig. 7, inserting tubing into
appropriate inlet or outlet quick-connecttting until it stops.
NOTE: In some installations, connecting the system to the water
supply adapter and/ordrinking water faucet causes the tubingto
enter the quick-connecttting at a sharp angle. This may exert
pressure on the quick-connecttting andcause it to leak. In these
situations, you may wish to use one or both of the quick-connect
elbows included with the installation kit. Simply push the quick-
connect elbow directly into the quick-connecttting on the system,
then insert the tubing into the quick-connectelbow.
(B) When cut between a set of black guide arrows, the tubingshould be
pushed into the tting so that the entrance of the tting falls between
the next set of guide arrows (approximately 5/8"[16 mm]).
8. Putting the System intoOperation
(A) Slowly turn on cold water supply.
(B) Shut o faucet openedbefore starting installation.
(C) Open water supply adapter.
(D) Rotate base ofdrinking water faucet counter-clockwise to “ON”

FILTER CARTRIDGEREPLACEMENT
• Filter cartridges the US-1000will last about500gallons or
six months before they need tobe replaced. Filter cartridge
life varies dependingon usage, and/orwater conditions.
Changes in taste, color, and ow of the water being ltered
indicate that the cartridge should be replaced.
• Read all instructions beforereplacing lter cartridges.
1. Turn o cold water supply and open the drinking water
faucet to release pressure from system.
2. Unscrew and remove bottomof lter housing. Locate and
remove large O-ring,wipe clean of lubricant, and set aside.
Repeat for second housing.
3. Discard used lter cartridges. Using a non-abrasivesponge
or cloth, scrub the bottom of lter housings, O-ringgrooves,
and caps with dish soap and warm water. Rinse thoroughly.
Fill bottomof each housing 1/3full with water. Add 1
tablespoon of household bleach and scrub to disinfect.
4. Lubricate O-ringswith silicone grease. Insert each O-ringin
grooveand press into place.
NOTE: This step is important to ensure a proper housing
seal. Make certain each O-ringis seated level in its grooveor
a leak may occur.
5. Screw bottomof housings with bleach water onto caps
without lter cartridges and hand-tighten.DONOT
OVERTIGHTEN.
6. Turn on water supply. Let faucet run for about 10seconds,
then turn o faucet and let stand for 20-30minutes.
7. Turn on faucet and allow bleach water to run out (about 3-5
minutes).
8. Turn o water supply to system and open faucet to release
pressure. Remove bottomof housings and empty of water.
9. Insert each lter cartridge in bottomof appropriate lter
housing: P-250ACartridge Set: white with green endcaps in
left housing, gray plastic cartridge in right housing.
NOTE:The lter cartridges should be installed with the black
gasketed ends pointing up.
10.Screw bottom of housings onto caps and hand-tighten. DO
NOTOVERTIGHTEN. Make certain cap standpipeslips into
cartridge.
11.Openwater supply and turn on drinking water faucet to
release pressure in system. Let faucet run for 5 minutes to
remove trapped air and carbon nes. Check system for leaks
before leaving installation.
NOTE:
• It is recommended that yourun the tap at least 20seconds
prior to using water for drinking or cookingpurposes.
• Initially, ltered water may appear cloudy.If you set a glass
of water on a level surface, youshould be able to watch the
cloudiness disappear from the bottomof the glass upwards.
This harmless cloudiness results from the release of trapped
air within the cartridge and will disappear within a few weeks
after installation.
