WARNING
When servicing equipment, use non-sparking tools and use caution when removing or
installing equipment to avoid generating a spark.

1. If a ball valve is installed down line from the pump, close it.

studs between the extractable's flange and the manifold will push the extractable up, breaking the seals.
