For Field Installations: These Cross Brace/Curb
Adaptors (two adaptors 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.
