Impinger holder on pump with
impinger and trap
Clip sampling medium to worker
and pump to belt.
High Flow Applications (Cont)
Set Up/Sample
• Allow pump to equilibrate after moving it from one temperature extreme to another.
• Protect sample pump from weather when in use outdoors.
• Powering the pump with any device other than the approved battery pack voids the UL Listing for intrinsic
safety.
• Do not use the pump with the Battery Eliminator in hazardous locations. UL Listing for intrinsic safety is not in
effect during pump operation with Battery Eliminator.
• Use of any device other than the approved battery pack or Battery Eliminator to power the pump voids any warranty.
• Charge pump battery completely before calibration and sampling.
• See User Options During Sampling.
1. Replace the sampling medium used for calibration with an unexposed medium for sample collection.
2. Place the sampling medium where appropriate for sampling.
a.
For personal sampling,
clip the sampling medium to the worker in the breathing zone.
See above
right.
b.
When using impingers, an in-line trap (SKC Cat. No. 225-22 or 225-22-01) is required to prevent
fumes from accidentally being drawn into the sampler.
Place the in-line trap between the pump and
the impinger. Mount the impinger and trap to the face of the sampler using the accessory mounting
screws
(Figure 1)
or place them in a holster at the worker’s waist.
Failure to use an appropriate in-line trap during impinger sampling voids any warranty.
c.
When using the pump for pressure applications, such as bag sampling,
thread the exhaust port
fi
tt
ing supplied with the pump into the air discharge port on top of the pump; hand-tighten only.
Using PTFE tubing, connect the inlet of the sample medium (e.g., sample bag) to the exhaust port
fi
tt
ing on the pump. Turn on the pump to collect the appropriate volume of air. Shut o
ff
the pump
and close inlet on sample medium to stop sampling.
3.
With the LCD displaying HOLD, start sampling by pressing Start/Hold
(Figure 1)
. SAMPLE RUNNING
will be displayed. Record the start time. The elapsed sampling time will be shown on the LCD.
4. At the end of the sampling period, press Start/Hold and record the stop time.
5. Seal the sample and send it with blanks and pertinent sampling information to a laboratory for analysis.
6. Verify
the
fl
ow.
a. Press Start/Hold to turn on the pump and reinstate the calibration train and sampling media.
b. Take three readings and record the average value as the post-sample
fl
ow rate.
Do not adjust the pump
fl
ow rate during this step.
c. Compare the pre and post-sample
fl
ow rates. Note in sampling documentation if the values di
ff
er by more than ± 5%.
User Options During Sampling
Pause -
Pause (shutdown) the pump by pressing Start/Hold. All timing data will freeze. To resume sampling, press Start/Hold;
timing data will resume.
Flow or Ba
tt
ery Fault Shutdown -
If the pump is unable to compensate due to excessive back pressure or a low ba
tt
ery
condition exists, the sampler will shut down. HOLD will display on the LCD and timing functions will pause but continue to
display elapsed time. 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 a
tt
empt 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 ba
tt
ery before sampling.
