Sloped Ladder Installation

When sloped ladders are supplied with a unit, they are shipped in the unit's basin. One sloped ladder will be provided for each cell.
Assembly is identical for each cell, unless otherwise noted in the submittal.
Sloped ladders are attached at a minimum of three points. At each point of attachment, the ladder will be fitted with a ladder
bracket assembly. The ladder bracket assembly looks like a metal box and is shown as component d in Figure 24 below. The upper
two assembly brackets will be rigidly mounted to the ladder and are not adjustable. These two brackets define the slope of the
ladder. The lower bracket(s) are adjustable.
To install the ladder assembly, complete the steps that follow. R efer to Figure 24:
