4.3 Changing the Process Con-
nection
The transmitter is shipped with the process connection
specified at the time of ordering. To change the process
connection,the drain (vent) plug must be repositioned.
To reposition a drain (vent) plug, use a wrench to
slowly and gently unscrew it. Then, remove and
remount it on the opposite side. Wrap sealing tape
around the drain (vent) plug threads (*1 in the figure
below), and apply a lubricant to the threads of the
drain (vent) screw(s) (*2 below). To tighten the drain
(vent) plugs, apply a torque of 34 to 39 N·m {3.5 to 4
kgf·m}. Process connector bolts are to be tightened
uniformly to a torque shown in table 4.1.
