Air handling unit installation
No more than one air handling unit may be protected with one ReadySET detector.
In this application, ensure that the sampling pipe is raised clear of high velocity air in the
immediate vicinity of the air intake grill on standoff posts as shown in Figure 4 below.

The ReadySET detector is supplied with an exhaust port (see Figure 2 on page 9). This
allows the ReadySET detector to sample from areas which may be at different air
pressure than the detector location. Typical uses are for air-duct sampling and allowing
the installation of the detector in under-floor or ceiling voids or when sampling from
pieces of computer related equipment. See Figure 5 on page 16 and Figure 6 on page
16.
