Align the metal bracket and tighten the four corner bolts evenly.
This pulls the rooftop AC and gasket together for a watertight fit.
Insert the mounting bolts through the bracket into the threaded holes of the rooftop unit. Use a ratcheting wrench or impact driver with a 9/16 socket. Tighten gradually in an X-pattern to evenly compress the gasket seal.
See the video for this install, of the overview of all the steps.
