the unit's weight when mounted to the structure.
This length may be dependent on the type of
construction.
7. Secure rain flashing to wall and caulk across entire
length of top (see Figures 2A and 2B).
8. On side-by-side installations, maintain a minimum of
20" clearance on right side to allow access to control

airflow to the outdoor coil. Additional clearance may
be required to meet local or national codes.
