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 3-1and 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
