Read the following information carefully before disassembling a device.

Process Sensor Body
NOTE
Do not leave devices in service once they have been determined
to be inoperable.
Be aware of the following:
• The process should be isolated from the device and vented before
the device is removed from service for disassembly.
• The process flange can be detached by removing the four flange
bolts and the two alignment screws that secure it.
CAUTION
To prevent damage which may lead to inaccurate measurements, do not
scratch, puncture, or depress the isolating diaphragms.
• Isolating diaphragms can be cleaned with a soft rag, mild
cleaning solution, and clear water rinse.
CAUTION
To prevent damage which may lead to inaccurate measurements, do not
use any chlorine or acid solutions to clean the diaphragms.
• The flange adapters and process flange can be rotated or reversed
for mounting convenience.
• When removing the process flange or flange adapters, visually
inspect the Teflon O-rings. Replace the O-rings if they show any
signs of damage, such as nicks or cuts. If they are undamaged,
they can be reused.
• If the Teflon sensor module O-rings have been replaced, re-torque
the flange bolts after installation to compensate for cold flow.
