External Platform and Vertical Ladder Installation
If your unit is accessorized with an external service platform assembly with a vertical ladder, this equipment is shipped in the basin
of your unit. In some cases, they are shipped separately due to other basin accessories that may interfere with storage. The
platform is partially assembled prior to shipment to minimize field assembly.
Typically, there is one working platform and ladder assembly per fan section. Refer to your factory submittal for details.

The platform and ladder assembly should be attached after the unit is fully rigged, by following the instructions in the
drawing below.
