Air-Gap Faucet Hook-Up

There are 3 colored tubing on your Air-Gap faucet. At the end of each 1/4” tubing there is a “Quick Connect” fitting. The Quick Connect fitting is used to connect the Pure and Rinse water line from the RO unit to the Air Gap Faucet.

To connect the lines, simply insert each line into the fitting port tightly.

Hook-Up:

  1. Assemble the faucet: There is a plastic “filler tube” in the slot next to the faucet’s on/off black lever. Remove this filler-tube, and immediately insert the faucet spout into the slot to prevent the black lever from falling out of its socket. Do Not press down the black lever until the spout is inserted into the slot.  Read more
