RE: PRECEDENT PACKAGED AIR CONDITIONERS - 2014 FLORIDA BUILDING CODE WIND LOAD
CALCULATIONS FOR ROOFTOP INSTALLATIONS
Mrs. Braddy,
Per your request, we have analyzed the PRECEDENT line of packaged rooftop air conditioners.
Our analysis was performed in accordance with the 2014 Florida Building Code using the
following Wind Design Criteria:
• Ultimate Wind Speed =186 miles per hour
• Risk Categories = III and IV
• Wind Exposures = C and D
• Mean roof heights of up to 60 feet above ground
I•
As a result, we have concluded that additional screws will be required for the PRECEDENT line
of units. These screws may be field installed and their locations are as shown on pages 4 thru 7.
All additional screws shall be #10 x%" long self -drilling stainless steel sheet metal screws.
The number of additional screws are based on the cabinet size and are as follows:
• Cabinet "B" —7 screws
• Cabinet "C" —14 screws
• Cabinet "D" —21 screws
• Cabinet "E"— 24 screws
We have included a list of the PRECEDENT model numbers analyzed and their respective
cabinet size on page 3.
Please note that our analysis and results pertain only to the units themselves and their ability to
maintain structural and panel integrity -under severe wind events. The attachment of the units
to the building structure and the adequacy of the underlying building structure are not our
