Operation
High Flow Applications (1000 to 3000 ml/min)
Set/Calibrate Flow Rate
• Allow pump to equilibrate after moving it from one temperature extreme to another.
• Charge battery completely before calibration and sampling.
1. Ensure that the baery 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/offbuon to turn offthe pump. Disconnect the calibrator and flexible 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.
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/offbuon 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 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 flow fault icon () depending on the cause of the shutdown. Upon flow fault, the pump will aempt to restart up
to five times. To restart from flow fault, correct the blockage and press the on/offbuon twice. The elapsed run time
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 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/offbu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 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 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 baery 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. Aach the Tygon tubing of the All-in-One to the pump inlet. Note: If the pump flow faults shortly after the holder is aached, 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 flow 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 puffof air.
2. Break tips offthe 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 flow adjust screw or use an oversize screwdriver to
adjust flow — valve or thread seat damage may result.
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 offthe pump by pressing the on/offbuon. Disconnect the calibrator
and tubing from the representative sorbent tube inlet.

Using a CPC and Dual, Tri, or Quad Adjustable Low Flow Tube Holder (Figure 3)
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 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 baery is fully charged and that the pump has run for 5 minutes before calibrating. Leave 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 seing would be 1500 + 225 = 1725 ml/min.)
* Back pressure 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
1. Aach the tubing on the CPC outlet (side of the CPC without a label) to the pump inlet. Aach
the Adjustable Low Flow Holder to the CPC inlet (marked “To Sample”). See Figure 4.
2. Break tips offthe representative sorbent tubes and insert the tubes into the rubber sleeves on
the holder (arrow on each tube pointing toward 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).
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 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.

Replace the Pump Inlet Filter
The AirChek 52 Sampler is fied 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 fiing (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 fiing is still in place.
4. Thread the inlet fiing 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 boom of pump case and allow them to fall to the out position.
2. Pinch baery pack release arms and pull the boom half of the pump case away from
the top half.
3. Align arms on top half of case with slots on either side of the new baery pack
housing. Ensure that the back of the baery pack with the charging jack is on the
same side as the belt clip.
4. Slide baery pack up until arms click into place.
5. Push each security screw into the baery 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.

Run Time Nickel-metal hydride (NiMH) battery: 12 hrs minimum at 2000 ml/min and up to 25 inches
water back pressure; depends on media used. See Table 1.
Battery Eliminator: Pump provides extended runs.
Power Supply Rechargeable 4.8-V NiMH battery pack, 3.3-Ah capacity
A Battery Eliminator is available (see Accessories); use voids the UL Listing for intrinsic safety.
Battery Charging Time
(varies with battery capacity
and level of discharge)
6 to 8.5 hrs with PowerFlex charger
Temperature Operating: 32 to 104 F (0 to 40 C)
Storage: -4 to 113 F (-20 to 45 C)
Charging: 50 to 113 F (10 to 45 C)
Humidity 0 to 95% non-condensing
Flow Fault If the pump is unable to compensate for longer than 15 seconds due to excessive back pressure, the pump
enters flow fault. During flow fault, the pump stops, the fault icon appears on the display, and elapsed
time remains on the display. Auto-restart is attempted up to 5 times. Note: Elapsed time information
will be lost on restart.
Low Battery Fault LCD displays low battery icon and pump shuts down. LCD remains on.
Time Display LCD shows elapsed pump run time in minutes up to 99,999.
Note: Older pump models display elapsed time up to three digits (999) and then roll back to zero.
LCD Indicator LCD always remains on. Displayed elapsed run time information resets when pump is started.

Table 1. Pump Run Time in Hours with NiMH Battery
Appendix (Cont)
Typical Run Times
Table 1 contains the typical run times achieved when using a fully charged NiMH baery pack. Data is sorted by type of sample media.
All run times are listed in hours. Results are obtained using a new pump and new fully charged baery. Pump performance may vary.
Increases in back pressure during sampling due to buildup of sample on the filter can decrease baery life.
