For Field Installations: These
Cross Brace/Curb Adapters (two
adapters ship with each rooftop
unit) must be repositioned when the
unit is mounted on a curb or
platform (one for each end). Simply
remove the screws, turn the piece
over (end for end) and secure in
place using the holes/hardware
provided. All joints and seams
must be sealed completely to
prevent leaks.
