Canadian Standards Association (CSA) configured pumps must be
electrically grounded using the grounding strap provided (Figure 1).
Improper grounding can cause improper and dangerous operation. To
properly attach the grounding strap to a CSA pump, identify the designated
grounding location on the muffler plate; using the provided self-tapping
screw and grounding wire, thread the grounding screw through the
grounding wire lug, into the muffler plate and tighten securely (Figure 2).
Completion of the pump grounding procedure must be done in accordance
with local codes, or in the absence of local codes, an industrial or nationally
recognized code having jurisdiction over the specified installation.
