Follow these steps:

1.Follow all plant safety rules and procedures.

2.Isolate and vent the process from the transmitter before removing the transmitter from service.

3.Remove the transmitter from the process connection.

a.The Rosemount 2051C Wireless transmitter is attached to the process connection by four bolts and two cap screws. Remove the bolts and screws and separate the transmitter from the process connection. Leave the process connection in place and ready for re-installation. Reference Figure 3-8 on page 39 for coplanar flange.

b.The Rosemount 2051T Wireless transmitter is attached to the process by a single hex nut process connection. Loosen the hex nut to separate the transmitter from the process. Do not wrench on neck of transmitter. See warning in “Inline process connection' on page 45.

4.Do not scratch, puncture, or depress the isolating diaphragms.

5.Clean isolating diaphragms with a soft rag and a mild cleaning solution, and rinse with clear water.

6.Whenever you remove the process flange or flange adapters, visually inspect the PTFE o-rings. Replace the o-rings if they show any signs of damage, such as nicks or cuts. Undamaged o-rings may be reused.
