Safety

Adequate precautions appropriate for the installation and location of these products should 
be taken to safeguard the equipment and the premises from damage and the public from 
possible injury. 

The procedures in this manual must be thoroughly reviewed prior to rigging 

and assembly. Read all dangers, warnings, cautions, and notes detailed in the margins.

When the fan speed of the unit is to be changed from the factory set speed, including the 
use of a variable speed device, steps must be taken to avoid operating at or near the fan’s 
“critical speed” which could result in fan failure and possible injury or damage. Consult 
with your local BAC Representative on any such applications.
