Lower the bowl assembly until it
rests securely on the support beams (see
Fig. 6).
Place over the top of the bowl unit a
specially made wood or metal apron that
covers the opening and fits closely
around the impeller shaft. Wrap a clean
rag tightly around the shaft, over the
apron (see Fig. 7). This will prevent
entry of foreign matter into the bowl
unit.
Take care not to drop tools, screws,
nuts, or any other foreign objects into
the bowl unit or sump. Such an object
could impair pump performance or
ruin the impellers. If passed by the
pump into the discharge piping, a
solid object could cause serious
damage to downstream components.
Any foreign object dropped into the
pump column must be retrieved before
proceeding with the pump installation.
If any foreign object is dropped into
the sump, it must be retrieved prior to
starting the pump.
Figure 7. Protect the top of the bowl
assembly to prevent the entry of foreign
objects.

or sump by a box-type clamp.
