Startup with new packing 6.2.5.4
Check to see that the by-pass line (if used) is
connected and the packing gland is loose. Start
pump and allow it to run for 20 to 30 minutes. Do not
tighten the gland during this "run-in" period even if
leakage is excessive. Should the new packing cause
excessive heating during "run-in", flush the shaft and
packing box area with cold water or shut the pump
down and allow to cool.
