Installation - Mechanical
• For parallel-to-airflow channels, size channels based on a four-point load distribution (see
Figure 13 .
• For perpendicular-to-airflow channels, size channels based on the load distribution of the
individual sections and install the channels so that both ends of every section are supported
(see
Figure 14 ).
Using Integral Base Frame
If using the factory-provided integral base frame for ceiling suspension, individual sections and/
or subassemblies will have base frame shipping splits and base frame lifting lugs. When using the
base frame for ceiling suspension:
• Suspend the unit (on both sides of the unit) at each shipping split lug as well as the four corners
of the unit (see
Figure 15 ). See Figure 7 and Table 8 on page 27 for lug hole sizes.
• Bolt shipping splits together.
Note: The hanger rods must extend through the bottom of the base lug. It is the building
engineer’s responsibility to provide the appropriate hangers.
