Remove a quick-release pin from hole A on each side.
Push on the outdoor unit to rotate it down until it is parallel with the exterior wall.
Return the quick-release pins to hole B on each side.
Use a level or a level app to check the alignment of the unit:
The top of the outdoor unit should slope between 3.5° away from the building to 0.5° towards the building.
The top of the indoor unit should slope between 1.5° toward the outdoors to 2.5° towards the indoors.
Ensure both units are no more than 1.5° off level from side to side.
