nozzle hose rather than undoing it take the hose guide and insert it into the hole where it belongs you'll now take the hose guide mounting nut and you will go under the sink and you will thread it on and tighten it by hand thread it on by hand and then tighten it by hand just to work snug just like that take the spray nozzle hose and feed it through the hose guide this particular faucet needs to be assembled by simply taking the spout and and screen it onto the base you will want to do this before you insert it into the sink take the deck plate gasket and place it on the bottom of the deck plate of the faucet insert the faucet into the openings I will take the Quick Connect adapter and I will snap it onto the end right here until you hear it click just like that once the faucet is in place thread the mounting nets on both sides and hand tighten
