Installation
• For standard under-sink installation on 1/2" 14 NPS threads (most common
thread on kitchen faucets) cold water line.
• Please read all instructions and precautions before installing and using your
MTBE Filtration System.
• Numbered diagrams correspond with numbered steps.
1. Installing the Water Supply Adapter
The supply adapter fits 1/2"-14 NPS supply threads. If local codes permit, it may
be used to connect the US-1000 to the cold water supply line. If local codes do
not permit the use of the supply adapter, alternate connectors can be obtained
from your local supplier.
(A) Turn off cold water supply line. If cold water line does not have a shut-off
valve under the sink, you should install one.
(B) Turn on the cold water faucet and allow all water to drain from line.
(C) Disconnect cold water line from 1/2"-14 NPS threaded stub on bottom of
main faucet.
(D) Apply Teflon
®
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 previously connected the cold water line to the faucet,
screw the cold water line to the male supply adapter threads.
2. Selecting the Faucet Location
NOTE: The drinking water faucet should be positioned with function,
convenience, and appearance in mind. An adequate flat area is required to allow
faucet base to rest securely. The faucet fits through a 3/4" hole. Most sinks have
pre-drilled 1
3
⁄
8
" or 1
1
⁄
2
" diameter holes that may be used for faucet installation. If
these pre-drilled holes cannot be used or are in an inconvenient location, it will
be necessary to drill a 3/4" hole in the sink to accommodate the faucet.
CAUTION:
This procedure may generate dusts which can cause severe
irritation if inhaled or come in contact with the eyes. The use of safety glasses
and respirator for this procedure is recommended.
CAUTION:
DO NOT ATTEMPT TO DRILL THROUGH AN ALL-PORCELAIN SINK.
If you have an all-porcelain sink, mount the faucet in pre-drilled sprayer hole or
drill through countertop next to sink.
CAUTION:
When drilling through a countertop make sure the area below the
drilled area is free of wiring and piping. Make certain that you have ample room
to make the proper connections to the bottom of the faucet.
CAUTION:
Do not drill through a countertop that is more than 1" thick.
CAUTION:
Do not attempt to drill through a tiled, marble, granite or similar
countertop. Consult a plumber or the countertop manufacturer for advice or
assistance.
(A) Line bottom of sink with newspaper to prevent metal shavings, parts, or tools
from falling down drain.
(B) Place masking tape over the area to be drilled to prevent scratches if drill bit
slips.
(C) Mark hole with center punch. Use a 1/4" drill bit for a pilot hole, then, using
a 3/4" drill bit or hole saw, drill a hole completely through the sink. Smooth
rough edges with a file.
3. Mounting the Faucet
(A) Remove wing nut and metal washer from the threaded shaft of the faucet.
Leave the black rubber washer on the threaded shaft.
(B) Slide the threaded shaft of the faucet into drilled hole.
(C) From under the sink, slide the metal washer on and thread on the wing
nut. Tighten the wing nut by hand until tight. It may be necessary to have a
second person to hold the faucet while tightening the wing nut.
NOTE: Do not overtighten the wing nut. Hand tighten only. Do not use pliers
or wrench to tighten.
