Sampling
Calibrate the sample pump for the
desired flow rate
(see Setting or Verifying
the Flow Rate, pages 7 & 8)
. Attach the
pump to a worker’s belt and the sampling
medium to the worker’s collar (near the
breathing zone). Turn on the pump.
Record the start time and any other
pertinent data. Monitor pump and
battery status by observing the LED
(see Reading the LED below)
. At the end
of the sampling period, record the stop
time. Cap the sample and send it with
pertinent sampling information to a
laboratory for analysis.
Caution:
Do not operate AirLite in hazardous or explosive
locations. AirLite is designed for applications that do not require
intrinsic safety.
Caution:
Protect sample pump from weather when in use
outdoors.
