Sampling
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.
Caution: Before use, allow pump to equilibrate after moving it
from one temperature extreme to another.
Calibrate the sample pump for the
desired fl ow rate (see Sett ing 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 batt ery 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.
Reading the LED
The LED on top of the pump case (Figure 1, #7) indicates pump
and batt ery status.
Slow fl ash ..................... Normal run
Fast fl ash ....................... Flow fault
Double fl ash ................ Low batt ery, approximately one-hour
run time remaining
Flash every
eight seconds ............... Pump shutdown due to
exhausted batt eries
Four fl ashes every
six seconds ................... Pump shutdown due to fl ow fault
Note: Indication of pump shutdown due to exhausted batteries will
override all other indicators.
