4.3 Changing the Process
Connection
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.
