Using your Elkay Avado Single-Hole Kitchen Faucet is easy. Simply use the lever handle to control the water flow and temperature. You can rotate it 45° forward and backward. For regular cleaning, use the steady stream function. When you need more power, switch to the powerful spray function of the pull - down spray head. The pull - down spray head can be extended for hard - to - reach areas of your sink. Just make sure to retract it gently to avoid damaging the nylon - braided hose. As for maintenance, the ceramic disc cartridge is removable for easy replacement if needed. Keep in mind that this faucet is lead - free and ADA compliant, so it meets high - quality standards. Always follow local regulations when installing the faucet, and if you use the optional escutcheon, make sure it's installed properly for different installation types.
