not extend all the way through the module housing, you have used a
bolt of incorrect length. Replace the bolt with one of the correct length,
and repeat the procedure. Optional flange adapters can be installed on
the process end of the three-valve manifold using the 1.75-inch flange
bolts supplied with the transmitter.
4. IF you replaced the Teflon sensor module O-rings, THEN re-torque
the flange bolts after installation to compensate for cold flow.
5. Install the drain/vent valve.
a. Apply sealing tape to the threads on the seat. Starting at the base
of the valve with the threaded end pointing toward the installer,
apply two clockwise turns of the sealing tape.
b. Take care to place the opening on the valve so that process fluid
will drain toward the ground and away from personnel when the
valve is opened.
c. Tighten the drain/vent valve to 250 in-lb.
NOTE
After replacing O-rings on Range 1 (DP) transmitters and re-installing the
process flange, expose the transmitter to a temperature of 185 °F (85 °C) for
two hours. Then re-tighten the flange bolts in a cross pattern, and again
expose the transmitter to a temperature of 185 °F (85 °C) for two hours before
calibration.
