INSTALLATION
PRESSURE CASE
When mounting the pressure case take care to prevent any side loading on
the Pressure Switch or the top end Delrin bulkhead cap. Over time, side
loading on those parts can cause a leak.

To minimize corrosion never mount the pressure case directly to metal. Isolate
the pressure case by wrapping it with vinyl tape at the contact points.
