Installation
Flush the hot and cold supplies thoroughly before installing the faucet!
Place the faucet and sealing washer on the mount- ing surface.
If the mounting surface is less than 3/16” thick, trim the sealing washer so that it is even with the bottom of the mounting surface.
From beneath the mounting surface, install the slide washer and collar nut. Tighten the collar nut by hand.
