Sampling with Impingers
When using impingers, place an in-line trap
between the pump and the impinger to
protect the sampler from liquid or vapors.
The impinger and trap can be mounted to
the sampler using the accessory mounting
screws (Figure 1, #8) or placed in a holster at
the worker’s waist.
Failure to use the impinger trap voids
any warranty.
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.
Pressure Applications (Bag Sampling)
When using the pump for pressure
applications, such as bag sampling,
thread the exhaust port fi tting supplied
with the pump into the air discharge
port on top of the pump (Figure 1, #15);
hand tighten only. Using PTFE tubing,
connect the inlet of the sample medium
(e.g., sample bag) to the exhaust port
fi tting on the pump. Turn on the pump
to collect the appropriate volume of air.
Shut off pump and close inlet on sample
medium to stop sampling.
