If there's no existing hole, drill a 1" hole at the desired faucet spot. Position it to allow the spout to swivel freely.
Remove the faucet from its package. Take off the tightening nut from its stem.
Place the faucet stem into the hole, ensuring the accompanying rubber gasket is flush with the sink surface for a proper seal.
Reattach and tighten the nut under the sink to secure the faucet. You may need someone to hold the faucet steady from above while you do this.
Push the blue tube into the faucet’s connector. Leave the other end disconnected for now; it will be attached later in the setup.
