The AutoPump is now ready for re-assembly by following the "Removing the Pump's Casing" steps above in reverse
order.
Notes:
1.
Before threading the bottom "spider" onto the pump's discharge tube, be sure to wrap the
discharge tube's threads completely with Teflon tape.
2.
Before inserting the two assemblies back into the pump's casing, apply PTFE grease to the two o-
rings
to make the next disassembly easier.
3.
When installing the (3) bolts that hold the inlet onto the bottom of the pump, these are to be
torqued to 75 in-lbs.
4.
Be sure to inspect the clips that hold the three EZ Fittings together, look for wear or stretching of
the clips.
