CAUTION — Some off the shelf, non-Pentair, 6” flange adapters will not work with pump without the strainer pot. Note
the tabs on the flange on the left, (Figure 3). These tabs will interfere with the strainer pot alignment
lip on the housing. This lip is used to locate the strainer pot on models that are so equipped. Please
contact Pentair for a replacement flange adapter kit (Pentair P/N 357212).
CAUTION — Use large diameter flat washers between the hex nut and the pump flanges to properly distribute the
clamping forces on the flange. Tighten the flanges to 20 ft.-lb. (27.1 newton/meters) unless otherwise
specified by the flange manufacturer. If it is not possible to use a torque wrench then care should be
taken not to over tighten the flange bolts. Failure to follow the above instructions can result in damage
to the pump flange.

CAUTION — Suction and discharge piping must be supported by an appropriate system of supports or hangers.
Inadequately supported pipe can cause excessive loads to be transmitted to the pump resulting in a
structural failure of the pump that could result in flooding and property damage.
