General Mounting
The ceiling must be strong and solid enough to protect the unit from vibration. All ceiling-cassette indoor units include a pattern to help deter-
mine the size necessary for the opening in the false ceiling (paper pattern dimensions match those for the ceiling opening dimensions), and
where the hanging bolts and refrigerant / drain piping are placed.
