NOTE: Please confirm if there is an existing hole available to install the Water Filter System faucet. If not, please drill a hole in accordance with the following steps.

 

*There is also a reference sticker to help you drill the hole. Remember to wear safety glasses to protect your eyes while drilling the faucet hole.

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 on your sink or countertop, and drill a hole referring to the sticker hole size;
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 firmly on the bit until you break through the surface;
5. Starting at the lowest speed, and hold the drill straight with firm pressure to prevent the bit from walking on the counter;
6. Once you break through the surface, swirl the drill a little to apply pressure in a circle evenly.
