Installation
For standard installation on 1/2-inch-14 NPS threads (most common thread on US kitchen faucets)
cold water line.
Please read all instructions and precautions before installing and using the US-EZ water filter.
Numbered diagrams correspond with numbered steps.
1. 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 9/16-inch
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
9/16-inch or 5/8-inch hole in the sink to accommodate the faucet.
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.
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 counter top next to sink.
When drilling through a counter top 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.
Do not drill through a counter top that is more than 1-inch thick.
Do not attempt to drill through a tiled, marble, granite or similar counter top. Consult a
plumber or the counter top manufacturer for advice or assistance.
Line bottom of sink with newspaper to prevent metal shavings, parts or tools from falling
down the drain.
Place masking tape over the area to be drilled to prevent scratches if drill bit slips.
Mark hole with center punch. Use a 1/4-inch drill bit for a pilot hole, then, using a 9/16-inch or
5/8-inch drill bit, drill a hole completely through the sink. Smooth rough edges with a file.

3. Installing the Water Supply Adapter
The supply adapter fits 1/2-inch-14 NPS supply threads.
Turn off cold water supply line.
Turn on the cold water faucet and allow all water to drain from line.
Disconnect cold water line from 1/2-inch-14 NPS threaded stub on bottom of main faucet.
NOTE:
If it is too difficult to access the threaded stub on the bottom of the cold water faucet, see
Alternate Installation on page 4.

tape onto male threads of faucet stub and supply adapter. Screw the water supply
adapter to the threaded faucet stub as shown.
Using the nut that previously connected the cold water line to the faucet, screw the cold water line
to the male supply adapter threads. Hand tighten nut and snug with wrench.
4. Mounting the Filter System

be easily accessible.
