Installation
• For standard under-sink installation on 1/2-inch 14 NPS threads (most common thread on
kitchen faucets) cold water line.
• Please read all instructions and precautions before installing and using your Monitored MTBE
Filtration System.
• Numbered diagrams correspond with numbered steps.
1. Installing the Water Supply Adapter
NOTE:
The supply adapter fits 1/2-inch-14 NPS supply threads. If local codes permit, it may be
used to connect the SY-2650 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 plumbing supplier.
(A)
Turn off the cold water supply. 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-inch-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. (See diagram).
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 7/16-inch hole. Most sinks have pre-drilled 1-3/8–inch or 1-1/2–inch 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 1/2-inch hole in the sink for the
faucet.
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. The following instructions apply to porcelain-coated cast iron and stainless steel
sinks only. Consult a professional plumber about installation on an all
porcelain sink.
(A)
Line bottom of sink with newspaper to prevent metal shavings, parts, or tools from falling
down drain.
(B)
If sink is porcelain-coated, place masking tape over area to be drilled to prevent excess chip-
ping of enamel. Use a cone-shaped grinding bit to grind away a 3/4-inch diameter circle of
porcelain before drilling.
(C)
Mark hole with center punch. Use a 1/4-inch drill bit for a pilot hole, then, using a 1/2-inch
drill bit, drill a hole completely through the sink. Smooth rough edges with a file.
3. Mounting the Faucet
(A)
Slide small black rubber gasket OR
(B)
gasket, aluminum escutcheon plate (first remove protective plastic), and large gasket onto
threaded faucet stem. Lower faucet stem through hole in the sink.
NOTE: Black rubber gasket is designed for smaller holes in sink. Aluminum escutcheon plate
with gaskets is designed for larger, pre-drilled holes.
(C)
Slide aluminum channel washer up faucet stem, followed by
(D)
black plastic stem nut. Tighten nut with fingers.
NOTE:
Do not use pliers to tighten stem-nut. Pliers may strip threads of faucet stem.
