Faucet Installation - Ispring RO500 Installation Instructions & Owner's Manual

5) Faucet Installation

Choose a suitable location on the sink or countertop and install the faucet on a flat surface,
as shown in the image below. You will need to drill a 1" hole (no larger than 1 1/2") if your
kitchen sink does not have an existing one.
How to drill a 1" hole in your sink or countertop
1. It's highly recommended to watch the YouTube video "How to Drill Faucet Holes" to get
a better understanding of the process. Depending on what kind of countertop you have, you
may want to hire an experienced professional to ensure the hole is drilled correctly.
2. Choose a 1/2" Diamond Core Bit for granite and a titanium drill bit for steel. Do NOT use a
hammer drill on natural stone, glass, and ceramic.
3. An indent should be made with a punch on steel before drilling to help guide the bit.
4. Use caution when drilling on a Porcelain sink, as it could be easily chipped. Set drill speed
on slow. Press the bit downward firmly until breaking through the slippery surface. Some
people found it is easier to secure the bit by drilling through a piece of wood that is firmly
pressed on the surface.
5. Use coolant to disperse heat. Choose water for granite and oil for steel. Use the Water
Suction Cup to hold coolant inside and prevent the drill bit from slipping.
6. Starting at the slowest speed, hold the drill firmly and vertically and prevent the drill bit
from slipping on the counter.
7. Once breaking through the smooth surface, swirl the drill a little to apply pressure in a circle
evenly.
Be patient and deliberate. It can take 20 – 40 minutes to drill through 1".
