™ size-selective inlets are used
with an internal impactor disk (provided).
The impactor disk functions as a
collection plate where particles larger
than the cut-size are trapped. The same
impactor disk is used for all impactors,
but it is
not used for the standard inlet .
To make sure unwanted (large) particles
remain trapped on the impactor disk, it is
necessary to apply 1 to 4 drops of
impactor oil on the impactor disk for
particles to stick to. Wipe off any excess oil if necessary.
N O T I C E
Size-selective impactors will not function unless an impactor disk is
installed. To ensure proper performance, the impactor disk should
be removed, cleaned and re-oiled prior to each use.
1. Remove the impactor by loosening the two captive screws that
hold the impactor in place.
2. Flip the instrument upside down
to remove the impactor disk.
