Directions for use
Chamber Aerator Installation
The chamber aerator is an optional attachment that is necessary if you are
experiencing a significant amount of water splash around your sink.
1. Find the notch located on the top of the chamber aerator and line it
up with the blue irrigation port on the chamber.
2. Gently press the chamber aerator against the chamber until it is
snug.
Note The chamber aerator is only capable of attaching to the chamber
if it is aligned correctly. It should go on relatively smoothly and
there is no need to force it onto the chamber.
