4. Locate the Rosemount 708 Transmitter and high temperature mounting hardware

on a horizontal section of the piping as close as possible to the equipment being
monitored.

5. Ensure the mounting location is free of foreign matter and corrosion to ensure good

contact between the piping and mounting hardware.

6. Insert the U-bolt through the standoff mounting hardware.
7. Tighten each nut to 90 in-lb (10 N-m) 

Figure 3-7

.

8. If commissioning the device, install the power module (see 

Figure 3-5

).

9. Ensure the power module cover is fully tightened to prevent moisture ingress. The

lip of the polymer power module cover should be in contact with the surface of the
polymer enclosure to ensure a proper seal. Do not over tighten.
