Loosen the brass ow adjust screw (Figure

pump by using the on/off switch (Figure
2, #1). Adjust the ow rate by turning the
ow adjust screw (Figure 3, #1) on the
holder until the calibrator indicates the
desired ow.
Do not adjust the ow on the pump.
Adjust the ow only by using the
ow adjust screw on the low ow holder.
Turn off the pump and disconnect the calibrator.
Replace the sorbent tube used for setting the ow with a new
unexposed sorbent tube for sample collection.
Place the appropriate size tube cover over the tube, and screw it into
place on the low ow holder.
Sampling
For personal sampling, clip the low ow
holder to the worker in the breathing zone.
Before use, allow pump to equilibrate
after moving it from one temperature
extreme to another.
Protect sample pump from weather when
in use outdoors.
Use of any device other than the approved
battery pack to power the pump voids
the UL Listing for intrinsic safety and any
warranty.
Start the sampling period by turning on the
pump using the on/off switch (Figure 2, #1),
and record the start time.
At the end of the sampling period, turn off the pump and record the
stop time.
To return to high ow, remove the low ow holder and deactivate the
regulator. See page 6.
