What does the typical installation process look like?
To install a curb adapter, first turn off power and/or gas supply and disconnect from the existing RTU. Ensure the existing return & supply ducts are not fastened to the unit, then lift the existing RTU off the curb with a crane, removing it from the roof. If there was a curb adapter already installed, remove it now to expose the original roof curb that is flashed into the building's roof. Prepare the surface of the original roof curb with the supplied gasket around the outside perimeter and around both supply and return ducts. Seat the new curb adapter on top of the original roof curb, ensuring a proper fitment and seal. Prepare the top of the curb adapter with gasket around the outside perimeter and around both supply and return duct openings. Lift unit with a crane over the curb adapter, aligning supply and return and lower into place until fully seated. Connect power and or gas as necessary.
