Use the Pump with AC Power (Power option in non-hazardous locations)
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 the Battery Eliminator.
The Ba ery Eliminator is an accessory that converts alternating current (AC) to direct current (DC) from which the pump can be operated
for extended runs. The Ba ery Eliminator should be used in non-hazardous locations only. See Accessories.
1. Remove the ba ery pack from the pump. See Replace the Ba ery Pack.
2. The Ba ery Eliminator is comprised of two pieces, a wall cube and a power adapter. Plug the wall cube into a standard wall outlet
and insert its plug end into the power adapter.
3. Fit the power adapter on the pump in place of the ba ery pack.

medium outlet to the pump inlet. See right.
4. Using a screwdriver, set the pump fl ow rate by turning the fl ow adjustment screw on top of the pump (Figure 1), clockwise to increase
or counterclockwise to decrease fl ow, until the calibrator indicates the method-specifi ed fl ow rate. Take a minimum of three readings
and record the average fl ow rate, as per OSHA/NIOSH instructions.
5. Press the on/off bu on to turn off the pump. Disconnect the calibrator and fl exible tubing from the representative sample medium
and proceed to Set Up/Sample.
Set Up/Sample
• Allow pump to equilibrate after moving it from one temperature extreme to another.
• Protect sample pump from weather when sampling 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 battery completely before calibration and sampling.
1. Replace the representative sample medium with new unexposed medium for sample collection.
2. Place the sample medium where appropriate for sampling.
a. For personal sampling, clip the sample collection medium to the worker in the breathing zone and the
pump to the worker’s belt using the belt clip.
Clip sample medium
to worker and pump
to belt.
When using an impinger, an in-line trap (SKC Cat. No. 225-22 or 225-22-01) is required between the pump and
impinger to prevent fumes from accidentally being drawn into the sampler. Failure to use an appropriate in-line
trap during impinger sampling voids any warranty.
b. For sampling with an impinger, mount the single or dual impinger and trap (SKC Cat. No. 225-20-01 or
225-20-02) to the face of the sampler using the accessory mounting screws (Figure 1) or place them in a
holster at the worker’s waist.
3. Press the on/off bu on to clear the elapsed time displayed on the LCD and to start sampling. Record the
Impinger holder on pump
with impinger and trap
start time and other pertinent information. The LCD will automatically display elapsed pump run time.
See below.
Possible Displays During Sampling
Flow or Ba ery Fault Shutdown - If the pump is unable to compensate due to excessive back pressure or a low ba ery
condition exists, it will shut down and timing functions will pause. The LCD will display either a ba ery-shaped icon
or a fl ow fault icon (
to fi ve times. To restart from fl ow fault, correct the blockage and press the on/off bu on twice. The elapsed run time
) depending on the cause of the shutdown. Upon fl ow fault, the pump will a empt to restart up
display will reset to 0 when the pump is restarted. If the ba ery icon is displayed, recharge the ba ery before sampling.
Displayed Elapsed Run Time - Elapsed run time is displayed continuously on the LCD. For elapsed times after 999
minutes, the display still shows elapsed time but alternates between displaying the fi rst two digits of the elapsed time
and the last three digits. For example, a pump that has run for 1,440 minutes would display fi rst “01” and then “440.”
The display maximum is 99 999, which is 99,999 minutes.
4. At the end of the sampling period, press the on/off bu on and record stop time and other pertinent information.

5. Cap the sample and send it with blanks and pertinent sampling information to a laboratory for analysis.
6. Verify the fl ow.
a. Turn on the pump and reinstate the calibration train and sample medium.
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 diff er by more than ± 5%.
Low Flow Applications (5 to 500 ml/min)
• Single-tube sampling requires the All-in-One Low Flow Holder; see the operating instructions for the All-in-One for details on its operation.
• Multiple-tube sampling requires a Constant Pressure Controller (CPC) and a Dual, Tri, or Quad Adjustable Low Flow Tube Holder accessory;
see the operating instructions for the CPC and Adjustable Low Flow Tube Holder for details on their operation.
Using the All-in-One Low Flow Holder (Figure 2)
Set/Calibrate Flow Rate for Single Tube
• Allow pump to equilibrate after moving it from one temperature extreme to another.
• Charge pump battery completely before calibration and sampling.
• Calibrate/verify pump fl ow rate before and after each sampling operation using the tube holder and
pump to be used for sampling.
• Set the fl ow rate through the pump fi rst and then calibrate the fl ow rate through the representative
sorbent tube.
• Two small inlet holes on the bottom of the built-in CPC of the All-in-One can become blocked.
Periodically inspect and, if needed, clean with a small pick and blow particles away with a puff of air.

2. Prepare the calibrator (see calibrator instructions). Using fl exible tubing, connect the calibrator outlet (suction port) to the pump inlet.
3. Set the pump fl ow rate to 1.5 L/min. Using a small screwdriver, turn the fl ow adjustment screw on top of the pump (Figure 1), clockwise
to increase fl ow or counterclockwise to decrease fl ow, until the calibrator indicates 1.5 L/min.
4. Remove tubing from the pump inlet.
Flow Rate Through Sorbent Tube
1. A ach the Tygon tubing of the All-in-One to the pump inlet. Note: If the pump fl ow faults shortly after the holder is a ached, check that
the needle valve is open by using a small fl at-head screwdriver to turn the fl ow adjust screw on the holder slightly counterclockwise. If fl ow fault
continues, check that the two small holes on the bo om of the built-in CPC are not blocked. If needed, clean them with a small pick and blow any
particles away with a puff of air.
2. Break tips off the representative sorbent tube and insert it into the rubber sleeve on the All-in-One (arrow on the tube points toward
the holder). Note: Ensure that the sorbent tube fi ts snugly in the rubber sleeve prior to sampling to avoid air leakage. Two sleeves, each with a
diff erent inner diameter, are supplied with the All-in-One.
3. Using fl exible tubing, connect the calibrator outlet to the inlet of the representative sorbent tube in the holder. See calibration train above
right.
In the next step, do not shut off fl ow completely with fl ow adjust screw or use an oversize screwdriver to
adjust fl ow — valve or thread seat damage may result.
4. Do not adjust the fl ow on the pump. Adjust the fl ow rate through the representative sorbent tube
