A. Nut
B. Process Seal
1. Loosen the nut that connects the transmitter head to the process seal.
2. Carefully lift the transmitter head.
3. On the probe, make sure that the upper surface of the process seal is clean and free from dust and
water. Wipe it clean with a dry and lint-free cloth.
4. Verify the spring-loaded pin at the center of the process seal is properly inserted. When inserted
properly only the plunger is seen above the edge inside the seal hole.
5. If the transmitter head is not mounted directly, attach the protection plug to the process seal to
protect the exposed parts from dust and water. If a protection plug is not available, then cover the
process seal with a plastic bag.
6. Rotate the new transmitter head so the device display faces the desired direction.
7. Tighten the nut. Max torque is 30 Lbft (40 Nm).
