• Please read all instructions and precautions before installing and using your US-640 Undersink Water Filter.
• Numbered diagrams correspond with numbered steps.

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

-inch hole. Most sinks have pre-

drilled 1

–inch or 1 

1

/

–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

-inch hole in the sink for 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 OR PORCELAIN-COATED SINK. For applications on

these types of sinks we recommend using the sprayer hole or mounting the faucet through the countertop.

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-inch thick.

CAUTION: 

Do not attempt to drill through a tiled, marble, granite or similar countertop. Consult a plumber or the coun-

tertop manufacturer for advice or assistance.

The following instructions apply to stainless steel sinks only.
(A) Line bottom of sink with newspaper to prevent shavings, parts or tools from falling down the drain.
(B) Place masking tape over the area to be drilled to prevent scratches if drill bit slips.
(C) Mark point with center punch. Using a 

1

/

-inch drill bit, drill a hole completely through the sink. Smooth rough edges

with a file.

(A) Slide small black rubber gasket OR
(B) gasket, aluminum escutcheon plate, 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.

(A) Turn off cold water supply and open nearest faucet to release pressure in pipes before starting installation. Place a tray

or towels under the cold water line to catch excess water.

(B) Select location under sink where filter is to be mounted. Use mounting bracket as a template to mark screw locations.

Mount filter in marked location using mounting bracket.

NOTE: (C) Allow 1

minimum of 2 inches (51 mm) of pipe above shut-off valve in case pipe must be re-cut at a later time. Deburr ends of
remaining pipe with a file.

(B) Push the quick-connect tee onto the bottom portion of cold water line. Push the quick-connect union onto the top por-

tion of the cold water line.
