Assembly Methods - Liberty Pumps 441 Manuel D'installation

A ssem bl y M et hods
There are three ways to assemble and install the battery back-up
pump, depending on sump pit diameter/depth and desire for a
truly redundant back-up system. Select appropriate method by
referring to Figure 1. Any method is acceptable, but Method A is
recommended. Examples are shown in Figure 2 as a visual aid.
Note: Always install the back-up sump pump as close to the
bottom of the sump pit as possible.
Note: All assembly methods require the back-up pump switch to
have free movement.
