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 Battery Eliminator is an accessory that converts alternating current (AC) to direct current (DC) from which the pump can be operated for extended runs. The Battery Eliminator should be used in non-hazardous locations only. See Accessories.

1. Remove the battery pack from the pump. See Replace the Battery Pack.
2. The Battery 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 battery pack.

Operation

High Flow Applications (1000 to 3000 ml/min)
Set/Calibrate Flow Rate

• Allow the pump to equilibrate after moving it from one temperature extreme to another.
• Charge battery completely before calibration and sampling.

1. Ensure that the battery is fully charged and that the pump has run for five minutes before calibrating. Leave the pump running.
2. Prepare the calibrator. See calibrator instructions.
3. Set up a calibration train: Using flexible tubing, connect the calibrator outlet (suction port) to the representative sample medium inlet. Using ¼-inch Tygon tubing, connect the sample medium outlet to the pump inlet. See right.
4. Using a screwdriver, set the pump flow rate by turning the flow adjustment screw on top of the pump (Figure 1), clockwise to increase or counterclockwise to decrease flow, until the calibrator indicates the method-specified flow rate. Take a minimum of three readings and record the average flow rate, as per OSHA/NIOSH instructions.
5. Press the on/off button to turn off the pump. Disconnect the calibrator and flexible tubing from the representative sample medium and proceed to Set Up/Sample.

Set-Up/Sample

• Allow the pump to equilibrate after moving it from one temperature extreme to another.
• Protect sample pump from the 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 a new unexposed medium for sample collection.
  2. Place the sample medium were 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 the 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 button to clear the elapsed time displayed on the LCD and to start sampling. Record the start time and other pertinent information. The LCD will automatically display elapsed pump run time.
See below.
Possible Displays During Sampling
Flow or Battery Fault Shutdown – If the pump is unable to compensate due to excessive back pressure or a low battery condition exists, it will shut down and timing functions will pause. The LCD will display either a battery- shaped icon or a flow fault icon ( ) depending on the cause of the shutdown. Upon flow fault, the pump will attempt to restart up to five times. To restart from flow fault, correct the blockage and press the on/off button twice. The elapsed run time display will reset to 0 when the pump is restarted. If the battery icon is displayed, recharge the battery 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 first two digits of the elapsed time and the last three digits. For example, a pump that has run for 1,440 minutes would display first “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 button and record stop time and other pertinent information.
High Flow Applications (Cont)
5. Cap the sample and send it with blanks and pertinent sampling information to a laboratory for analysis.
6. Verify the flow.
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 flow rate. Do not adjust the pump flow rate during this step.
c. Compare the pre and post-sample flow rates. Note in sampling documentation if the values differ 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 the pump to equilibrate after moving it from one temperature extreme to another. · Charge pump battery completely before calibration and sampling.
• Calibrate/verify pump flow rate before and after each sampling operation using the tube holder and pump to be used for sampling.
• Set the flow rate through the pump first and then calibrate the flow 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.

Pump Flow Rate

1. Ensure that the battery is fully charged and that the pump has run for 5 minutes before calibrating. Leave the pump running.
2. Prepare the calibrator (see calibrator instructions). Using flexible tubing, connect the calibrator outlet (suction port) to the pump inlet.
3. Set the pump flow rate to 1.5 L/min. Using a small screwdriver, turn the flow adjustment screw on top of the pump (Figure 1), clockwise to increase flow or counterclockwise to decrease flow until the calibrator indicates 1.5 L/min.
4. Remove tubing from the pump inlet.

Flow Rate Through Sorbent Tube

1. Attach the Tygon tubing of the All-in-One to the pump inlet. Note: If the pump flow faults shortly after the holder is attached, check that the needle valve is open by using a small flat-head screwdriver to turn the flow adjust screw on the holder slightly counterclockwise. If the flow fault continues, check that the two small holes on the bottom 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 fits snugly in the rubber sleeve prior to sampling to avoid air leakage. Two sleeves, each with a different inner diameter, are supplied with the All-in-One.

3. Using flexible 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 flow completely with a flow adjust screw or use an oversize screwdriver to adjust flow — valve or thread seat damage may result. Turn the screw on a holder to adjust flow.
   

4. Do not adjust the flow on the pump. Adjust the flow rate through the representative sorbent tube using a small flat-head screwdriver to turn the flow adjust screw on the All-in-One (counterclockwise to increase, clockwise to decrease) until the calibrator displays the method-specified flow rate. Take a minimum of three readings and record the average flow rate, as per OSHA/NIOSH instructions.

5. When calibration is complete, turn off the pump by pressing the on/off button. Disconnect the calibrator and tubing from the representative sorbent tube inlet.

Set-Up/Sample with Single Tube

• Allow the pump to equilibrate after moving it from one temperature extreme to another.
• Protect sample pump from the weather when sampling 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.
• Charge pump completely before calibration and sampling.
• Calibrate/verify pump flow rate before and after each sampling operation using the tube holder and pump to be used for sampling.
  Clip tube holder to worker and pump to belt.

1. Replace the representative sorbent tube used for calibrating flow with a new unexposed sorbent tube for sample collection. Note: Ensure the sorbent tube fits snugly in the rubber sleeve of the All-in-One before sampling to avoid any air leakage. Two sleeves, each with a different inner diameter (ID), are supplied. Clip tube holder to worker and pump to belt.

2.  Place the tube cover over the tube (Figure 2) and thread it into place on the All-in-One low flow holder.

3.  Place the sorbent tube where appropriate for sampling. For personal sampling, clip the sample medium to the worker in the breathing zone and the pump to the worker’s belt.

4. Press the on/off button to clear the elapsed time displayed on the LCD and to start sampling. Record the start time and other pertinent information. The LCD will automatically display elapsed run time. See below.
   Possible Displays During Sampling

Low Flow Applications (Cont)
Using a CPC and Dual, Tri, or Quad Adjustable Low Flow Tube Holder (Figure 3)

Figure 3. Quad Adjustable Low Flow Tube Holder

Set/Calibrate Flow Rate for Multiple Tubes

• Requires Constant Pressure Controller (CPC) and Adjustable Low Flow Tube Holder (see Accessories). The low flow tube holder used with CPC allows up to four tube samples to be taken simultaneously, each at different flow rates if desired.
• Allow the pump to equilibrate after moving it from one temperature extreme to another.
• Charge pump battery completely before calibration and sampling.
• Calibrate/verify pump flow rate before and after each sampling operation using the tube holder and pump to be used for sampling.
• Set the flow rate through the pump first and then calibrate the flow rate through each representative sorbent tube.

Pump Flow Rate
Follow these important steps before proceeding.

1. Ensure that the battery is fully charged and that the pump has run for 5 minutes before calibrating. Leave the pump running.

2. Prepare a calibrator (see calibrator instructions). Using flexible tubing, connect the calibrator outlet (suction port) to the pump inlet.

3. Calculate the sum of all-tube flow rates. The maximum flow rate through any one tube is 500 ml/min.
   a. If the sum is 1000 ml/min, set the pump flow rate to 1.5 L/min. b. If the sum is > 1000 ml/min, multiply that number by 0.15 and total the two numbers. Set the pump flow rate for the resulting new sum. (Example: Sampling with three sorbent tubes, each with a flow rate of 500 ml/min. The sum of the tube flow rates is calculated as 3 x 500 = 1500. Determining a 15% higher flow rate is calculated as 1500 x 0.15 = 225. Calculating the final pump flow setting would be 1500 + 225 = 1725 ml/min.) * Backpressure across some sample tubes can be higher than average. In these instances, the maximum flow rate of 500 ml/min per tube may not be achieved.

4. Using a small screwdriver, turn the flow adjustment screw on top of the pump (Figure 1) (clockwise to increase flow or counterclockwise to decrease flow) until the calibrator indicates the required flow rate.

5. Remove tubing from the pump inlet and calibrator outlet.

Flow Rate Through Sorbent Tubes

Figure 4. Calibration Train with Quad Adjustable Low Flow Tube Holder

1. Attach the tubing on the CPC outlet (side of the CPC without a label) to the pump inlet. Attach the Adjustable Low Flow Holder to the CPC inlet (marked “To Sample”). See Figure 4.

2. Break tips off the representative sorbent tubes and insert the tubes into the rubber sleeves on the holder (arrow on each tube pointing toward the pump). Place unopened tubes in any unused ports to “seal” them.

3. Label all representative tubes and ports.

4. Using flexible tubing, connect the exposed end of the first active tube to be calibrated to the calibrator outlet (suction port).

5. Using a small screwdriver, loosen and turn the brass flow adjust screw (see above right) directly beneath the port holding the first active tube to be calibrated (clockwise to increase, counterclockwise to decrease) until the calibrator indicates the method-specified flow rate. Do not adjust the flow rate on the pump.
   Note: For tri and quad models, first rotate each anti-tamper cover to expose the flow adjust screws, then adjust the appropriate one until the calibrator indicates the desired flow (Figures 3 and 5).
   Figure 5. Cut-away of Tri/Quad Adjustable Low Flow Tube Holder

6. Repeat Steps 4 and 5 for each active representative tube.
   Note: Changing the flow on one tube will not affect the flow rate through the remaining tubes.

7. Once the flow is calibrated for each active tube, it is recommended practice to re-check the flow rate through representative tubes before removing them. Any adjustment should be minimal.

Set-Up/Sample with Multiple Tubes

Requires Constant Pressure Controller (CPC) and Adjustable Low Flow Tube Holder (see Accessories). The low flow tube holder used with CPC allows up to four tube samples to be taken simultaneously, each at different flow rates if desired.

• Allow the pump to equilibrate after moving it from one temperature extreme to another.
• Protect sample pump from the weather when sampling outdoors.
• Use of any device or battery pack other than P85004 or P84002 to power the pump voids the UL Listing for intrinsic safety.
• Charge pump completely before calibration and sampling.
• Calibrate/verify pump flow rate before and after each sampling operation using the tube holder and pump to be used for sampling.

1. Replace the representative sorbent tubes used for calibration with new unexposed sorbent tubes for sample collection.

2. Place a protective tube cover over each tube and thread into place on the holder until secure.

3. Place the adjustable holder with tubes that were appropriate for sampling. For personal sampling, clip the low flow tube holder to the worker in the breathing zone and the pump to the worker’s belt.

4. Press the on/off button to clear the elapsed time displayed on the LCD and to start sampling. Record the start time and other pertinent information. Sample for the time specified in the method used. The LCD will automatically display elapsed run time.
   Possible Displays During Sampling
   Flow or Battery Fault Shutdown – If the pump is unable to compensate due to excessive back pressure or a low battery condition exists, it will shut down and timing functions will pause. The LCD will display either a battery- shaped icon or a flow fault icon ( ) depending on the cause of the shutdown. Upon flow fault, the pump will attempt to restart up to five times. To restart from flow fault, correct the blockage and press the on/off button twice. The elapsed run time display will reset to 0 when the pump is restarted. If the battery icon is displayed, recharge the battery 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 first two digits of the elapsed time and the last three digits. For example, a pump that has run for 1,440 minutes would display first “01” and then “440.” The display maximum is 99 999, which is 99,999 minutes.

5. At the end of the sampling period, press the on/off button and record stop time.

6. Cap the sample tubes and send with blanks and pertinent sampling information to a laboratory for analysis.

7. Verify the flow.
   a. Turn on the pump and reinstate the calibration train and sample media.
   b. Take three readings and record the average value as the post-sample flow rate. Do not adjust the pump flow rate during this step.
   c. Compare the pre and post-sample flow rates. Note in sampling documentation if the values differ by more than ± 5%.

Maintenance

Replace the Pump Inlet Filter
The AirChek 52 Sampler is fitted with a filter/trap just below the pump inlet. This prevents particles from being drawn into the pump mechanism. The filter should be replaced periodically as follows:

1. Grip the inlet fitting (see right) and turn it counterclockwise to unthread it.

2. Holding the pump upside down, use a small flat-head screwdriver or tweezers to remove the filter.

3. Place a new filter in the inlet. Ensure that the rubber gasket inside the inlet fitting is still in place.

4. Thread the inlet fitting back into place.

Replace the Battery Pack
Use of a repaired or rebuilt battery pack voids any warranty and the UL Listing for intrinsic safety.

1. Loosen two security screws on the bottom of the pump case and allow them to fall to the out position.

2. Pinch the battery pack release arms and pull the bottom half of the pump case away from the top half.

3. Align arms on the top half of the case with slots on either side of the new battery pack housing. Ensure that the back of the battery pack with the charging jack is on the same side as the belt clip.

4. Slide battery pack up until arms click into place.

5. Push each security screw into the battery pack housing and tighten.

Once installed, completely charge the new battery pack before operating the pump (see Charge the Battery Pack). It may be necessary to charge it a few times before achieving maximum battery capacity.
