INSTALLATION
• For standard under-sinkinstallation on 1/2"14NPS threads (most
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

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
