4.3 Changing the Process Con-
nection
The transmitter is shipped with the process connection
specified at the time of ordering. To make a change
such as modifying the drain (vent) plug(s) attached to
the upside of the cover flange on shipment to be
attached to the downside follow the procedure below.
To begin, use a wrench to slowly and gently unscrew
the drain (vent) plug(s). Then, remove and remount
them 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 screw it (them) in. To tighten
the drain (vent) plugs, apply a torque of 34 to 39 N·m
{3.5 to 4 kgf·m}. Tighten the process connector bolts
uniformly to a torque of 39 to 49 N·m {4 to 5 kgf·m}.
