2) Fit the inlet and monitoring head. The inlet

comprises a 65 x 65mm round-to-square socket

that houses the PM

impactor, a plastic funnel

and an aluminium threaded top (see photo top

right). The monitoring head comprises a threaded

aluminium rod fitted to a round PVC boss (see

photo bottom right). Fit the inlet to the top of the

post (the square socket will slide onto the post)

and then screw the monitoring head onto the top

of the inlet. At this point, using a permanent

marker or correction fluid, mark both the inlet

socket and the post beneath it on the same side.

The inlet has to be removed later to install the

sampler and lining up the two marks each

time will ensure the head is correctly aligned

every time it is removed.

3) Fit the alignment peg. (See photo bottom

right) Using a compass or GPS locate north at the

monitoring location. The alignment peg must now

be fitted to the monitoring head pointing north.

Carefully drill a 6mm diameter hole 10-15mm

deep into the bottom of the round-section of the

monitoring head (see photo right). Place a small

amount of solvent-cement or superglue on one

end of the plastic dowel and insert it into the

drilled hole, at least 5mm should be exposed. It is

essential that the alignment peg points to

magnetic north. This ensures that the mounting

cylinder will be aligned to north when it is subse-

quently installed.

4) Install the mounting cylinder. The mounting

cylinders can be found inside the carrying flasks,

they are pre-loaded with sticky pad dust collection

slides. Remove a cylinder from a flask and with

the orientation notch facing down, slide it over the

monitoring head. Rotate the cylinder until the

notch locates over the north alignment peg.

Do not remove the sticky pad backing paper until

the DS500X sampler unit has been installed.
