Before You Begin

These instructions assume there's a grounded electrical outlet in the sink cabinet. If there isn't one, hire an electrician to run a new power source to power the sink dispenser. This new line has to provide GFCI (ground fault circuit interrupter) protection. It also assumes the sink has a pre-cut mounting hole in the sink. If there is no hole, you can cut a new one in stainless steel using a bimetal hole saw. If you have a cast iron sink set in a laminate or solid surface countertop, you can drill a hole for the dispenser faucet in the countertop.

  • Step 1 : Locate the dispenser's faucet hole

    Locate the dispenser's faucet hole

    On most aluminum sinks there is an unused precut mounting hole that's covered with a snap cap or screw-on cover. Remove the hole cover and use a flashlight to take a look at where the hole lines up beneath the sink cabinet.

  • Step 2 : Install the faucet

    Install the faucet

    Feed the dispenser through the hole by straightening the supply tubes attached to them. Then slip the mounting basket over the tubes and up to the base of the faucet. Push the tubes through the sink holes and use a basin wrench to tighten the mounting bracket from below the cabinet.
