Troubleshooting
Inspect the Teflon sensor module o-rings. If the o-rings are not damaged, reuse them.
Replace o-rings that show any signs of damage, such as nicks, cuts, or general wear.
Install the process flange on the sensor module. To hold the process flange in place,
install the two alignment screws to finger tight (screws are not pressure retaining). Do
not overtighten; this will affect module-to-flange alignment.
Install the appropriate flange bolts.

top of the module housing.
If the installation uses a manifold, then install flange adapters on the process end of the
