Pump and shaft alignment check – Long-
coupled
After connecting the piping, rotate the pump drive
shaft clockwise (viewed from motor end) by hand
several complete revolutions to be sure there is no
binding and that all parts are free. Recheck shaft
alignment (see section 4.5). If piping caused unit to
be out of alignment, correct piping to relieve strain on
the pump.
