transmitter:
1. Remove the cover on one of the two electrical
connection ports on the upper sides of the
transmitter housing.
2. Install various adapters and bushings on the
inch NPT internal threads of connection ports, if
necessary, to conform to factory wiring (conduit)
standards.
3. Remove the cover on the side of the field

possible. When installing the drip ring, the
bottom should be lower than the conductor pipe
connector and the transmitter housing.
7. Rotate after installing the cover, so that the O-
ring is loaded into the shell, and then continue to
tighten manually until the metal part of the cover
contacts with the metal part of the shell.
