during pump operation with Battery Eliminator.

• Use of any device to power the pump, other than the approved battery pack or Battery Eliminator, voids any warranty.

1. Replace the sample medium used for calibration with an 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.

b. When using an impinger, 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 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.

Failure to use an appropriate in-line trap during impinger sampling voids any warranty.

Possible Displays During Sampling

Flow or Batt ery Fault Shutdown - If the pump is unable to compensate due to excessive back pressure or a low batt ery condition exists, it will shut down and timing functions will pause. The LCD will display either a batt ery-shaped icon or a fl ow fault icon (

) depending on the cause of the shutdown. Upon fl ow fault, the pump will att empt to restart up to fi ve times. To restart from fl ow fault, correct the blockage and press the on/off butt on twice. The elapsed run time

display will reset to 0 when the pump is restarted. If the batt ery icon is displayed, recharge the batt 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 butt on and record stop time.

Set/Calibrate Flow Rate for Multiple Tubes

Follow these important steps before proceeding.

1. Ensure that the batt ery is fully charged and that the pump has run for fi ve minutes before calibrating. Leave pump running.

2. Prepare a calibrator (see calibrator instructions). Using fl exible tubing, connect the calibrator outlet to the pump inlet.

3. Calculate the sum of all tube fl ow rates. The maximum fl ow rate through any one tube is 500 ml/min.* a. If the sum is ≤ 1000 ml/min, set the pump fl ow 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 fl ow rate for the resulting new sum. (Example: Sampling with three sorbent tubes, each with a fl ow rate of 500 ml/min.* The sum of the tube fl ow rates is calculated as 3 x 500 = 1500. Determining a 15% higher fl ow rate is calculated as 1500 x 0.15 = 225. Calculating the fi nal pump fl ow sett ing would be 1500 + 225 = 1725 ml/min.)

* Back pressure across some sample tubes can be higher than average. In these instances, the maximum fl ow rate of 500 ml/min per tube may not be achieved.

4. Set the pump fl ow rate by using a small screwdriver to 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 the required fl ow rate.

5. Remove tubing from the pump inlet.

6. Insert an opened sorbent tube into each rubber sleeve on a low fl ow tube holder (Figures 3 and 4). Ensure that the arrow on each tube

points toward the tube holder. Insert an unopened tube in any unused port.

9. Place a Constant Pressure Controller (CPC) in line between the tube holder and the pump (Figure 4). a. Insert the inlet of the CPC (marked “To Sample”) into the black rubber tubing at the end of the tubing att ached to the tube holder.

Turn screw on tube holder to adjust fl ow.

b. Insert the short length of ¼-inch Tygon tubing supplied assembled to the CPC outlet (side without a label) onto the pump inlet.

10. Using fl exible tubing, connect the outlet of the calibrator to the exposed end of the fi rst sorbent tube in the holder (tube in the port opened in Step 8) (Figure 4).

11. Do not adjust the fl ow on the pump. Adjust the fl ow rate through the sorbent tube by turning the fl ow adjust screw on the tube holder (counterclockwise to increase, clockwise to decrease) until the calibrator displays 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.

12. When the method-specifi ed fl ow is set on the fi rst tube, turn off the pump by pressing the on/off butt on. Disconnect the calibration tubing from the fi rst tube. Repeat Steps 8 through 12 for each of the other active tubes. Note: Changing the fl ow on one tube will not aff ect the fl ow rate through the

remaining tubes.

13. When calibration is complete, turn off the pump by pressing the on/off butt on. Disconnect the calibration tubing from the last sorbent tube.

The AirChek 52 Sampler is fi tt ed with a fi lter/trap just below the pump inlet. This prevents particles from being drawn into the pump mechanism. The fi lter should be replaced periodically as follows:

1. Grip the inlet fi tt ing (see right) and turn it counterclockwise to unthread it.

2. Holding the pump upside down, use a small fl athead screwdriver or tweezers to remove the fi lter.

3. Place a new fi lter in the inlet. Ensure that the rubber gasket inside the inlet fi tt ing is still in place.

4. Thread the inlet fi tt 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 bott om of pump case and allow them to fall to the out position.

Appendix (Cont)

Typical Run Times

Table 1 contains the typical run times achieved when using a fully charged NiMH batt 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 batt ery. Pump performance may vary.

Increases in back pressure during sampling due to buildup of sample on the fi lter can decrease batt ery life.
