2.2.1 Inlet Hood - Assembly and Adjustment
The inlet hood can either be the pyramid shaped TSP type, or the larger circular SSI
type - see Figure 1. The inlet hood also serves to retain the filter cassette in position
and to clamp the cassette to the sampler to eliminate leaks.
Note: The HiVol 3000 is compatible with inlets from
the previous Ecotech Model 2000 High Volume Air
Sampler. The inlets are interchangeable without
modification to the sampler.
Remove the two bolts and washers, located at the top of the back legs of the sampler,
which will act as the pivot points for the inlet hood. Also remove the nut and bolt
from the threaded insert on the stay, which extends from the small slot on top of the
sampler. The stay supports the inlet hood during filter changes and calibrations.
Place the inlet hood on top of the sampler with the two mounting holes towards the
rear of the sampler, lined up with the pivot screw holes. This may require moving the
inlet hood to align the holes with the slots.
Insert the pivot screws through the holes in the inlet hood and sampler. The bolts
should not be tightened at this stage.
