SECTION TWO
SET-UP
2.1
GENERAL SET-UP
Place the unit in the desired sampling area. Make cer-
tain the unit is standing in a vertical position.
NOTE
When using rotameters, it is important to maintain a vertical
position for optimum accuracy. The rotameter provided in this
sampler has been tested for accuracy and is within
±
5% of full
scale.
2.1.1
Sampling Mast
To set up the Sampling Mast, perform the following
steps:
1)
First, unfold the legs at the bottom of the mast
stand by opening the locking knob and pulling the
legs outwards as far as they will extend.
2)
Loosen the largest locking collar at the bottom of
the stand and pull out by the second largest lock-
ing collar. Tighten the largest collar.
3)
Holding the extended section, loosen the second
largest locking collar and extend the next section
of the mast. Tighten the second largest collar.
4)
Repeat this procedure until the mast is extended to
its full or required height.
5)
Be sure to tighten each locking collar before pro-
ceeding to loosen the next. Position the extended
mast next to sampler.
2.1.2
Air Hose
To attach the Air Hose, perform the following steps:
1)
Connect one end of the flexible tubing to the air in-
let valve located at the front of the sampler.
2)
Connect the hose support tip to the top of the ex-
tended sampling mast.
3)
Insert tubing through the hose support tip, with 2–
3" of the hosing extending out.
4)
Insert filter cassette or other media into air hose
end.
2.1.3
Filter Cassettes
To install the Filter Cassette, do the following:
1)
First, remove any cap plugs from the filter cassette.
These may be colored in red and blue. Also re-
move the end of the filter cassette to expose the fil-
ter. This is called “open-face” filter sampling. This
allows air to enter the cassette freely with minimal
back pressure.
2)
Plug the filter cassette into the end of the sampling
hose.
