1. Choose a diamond core bit for granite, and a carbide drill bit for stainless steel.
Do not use a hammer drill on natural stone, glass, or ceramic.
2. Glue the sticker to your sink or countertop, and drill a hole referring to the size
shown on the sticker (1⅜”).
3. Make an indent with a center punch on a stainless-steel sink before drilling to
help guide the bit.
4. Be careful when drilling on a porcelain sink, as it can be easily chipped. Apply
downward pressure rmly to the bit until breaking through the surface.
5. Starting at the lowest speed, hold the drill straight with rm pressure to prevent
the bit from walking on the counter.
6. Once breaking through the surface, swirl the drill a little to apply pressure in a
circle evenly.
Step 1: Install the Feed Water Adapter (3/8” or 1/2”)
1. Shut off the water supply. Turn on the faucet to release the water pressure.
NOTE: Make sure the water has stopped before proceeding to the next step.
Use a towel or bucket to catch any excess water.
2. Disconnect the cold water pipe from the cold water supply valve.
3. Tighten the converter. Twist the feed water adapter onto the cold water supply
valve (with its washer) and tighten it using an adjustable wrench (Figure 4).
NOTE: If the cold water pipe is 1/2”, unscrew the converter from the A end of
the feed water adapter, and then screw it on the B end of the feed water adapter
(Figure 5).
4. Twist the cold water pipe (with its washer) onto the feed water adapter and
tighten it with an adjustable wrench.
