Tapping into the cold water line
(Using the water supply adapter model FW 1)
Drilling the hole for the faucet
1. For best results, a ½” carbide-tipped drill bit should be used to drill a hole into your sink for the
auxiliary faucet.
2. Carefully select the faucet location making sure it will have a neat water fall pattern and that
the faucet stud will be accessible from below once the hole is completed.
3. For Porcelain Sink: Before starting the drill motor, apply firm downward pressure on the bit until
a crunching occurs. This will help keep the drill bit from moving.
4. For Stainless Steel Sink: Before using a ½” carbide drill bit, an indent should be made with a
center punch to keep the drill bit from moving. A small pilot hole will also aid the ½” drill bit.
5. For best results, keep steady firm pressure during the start of the hole will cause excess wear
on the bit and progress will be slow.
6. Once the hole is complete, clean the area of metal chips and roughness around the hole.
Metal chips will stain Porcelain.

water supply only.
1. Turn off the cold water supply to the sink faucet
by locating the Round or oblong handle on the
right side of the sink cabinet and Turning clockwise
until the water supply is off.
NOTE: If the cold water shut-off valve fails to turn off the water, the
house water supply can be turned off at the main water supply.
2. The water supply adapter can be installed at the faucet Connection (A of Fig. #3) of the cold
water line or at the shut-off Valve connection (B of Fig. #3).
3. Disconnect the threaded nut at the connection and thread the water supply adapter, with
the flat washer in place, onto the connection and tighten. Connect the white tubing to the
water supply adapter with the treaded nut and tighten.
4. Thread the needle valve into the adapter tightly and turn the handle clockwise all the way in.
Turn on cold water supply to the sink faucet and check for leaks.
