MOUNTING 1. Locate the 708 on a section of piping as close as possible to the
equipment to be monitored. Align the waveguide of the transmitter as
shown in Figure 3-1 and Figure 3-2.
2. The mounting location should be free of foreign matter and corrosion
to ensure good contact between the piping and the waveguide.
3. Tighten each clamp to 10.2 N-m (90 in-lb). Trim the excess clamp
band material to prevent unwanted acoustic noise.
4. If commissioning the device, install the Green Power Module (see
Figure 3-3 on page 3-2).
5. Ensure that 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.
