timing data will freeze. To resume sampling, press Start/Hold;
timing data will resume.
Flow or Battery Fault Shutdown - If the pump is unable to
compensate due to excessive back pressure or a low battery
condition exists the sampler will shut down. HOLD will display
on the LCD and timing functions will pause, but continue to display
total elapsed time or pump time when buttons are pressed. LO
BATT or FLOW FAULT will display on the LCD depending on
the cause of the shutdown. Fifteen seconds after fl ow fault shut
down, the pump will attempt to restart up to fi ve times. To restart
from fl ow fault, correct the blockage and press Start/Hold. If LO
BATT is displayed, recharge the battery before sampling.
Display Times - Elapsed sampling period is continuously
displayed on the LCD. Press and hold Pump Run Time

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, #12)
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, #19); 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.
Thread exhaust
port fi tting into air
discharge port on
pump.
