Set/Calibrate Flow Rate for Multiple Tubes

• Requires Constant Pressure Controller (CPC) and Adjustable Low Flow Tube Holder (see Accessories). The low ﬂ ow tube holder used with CPC allows up to four tube samples to be taken simultaneously, each at different ﬂ ow 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 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 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 ﬂ exible tubing, connect the calibrator outlet (suction port) 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 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 ﬂ ow rate of 500 ml/min per tube may not

be achieved.

4. 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 the required ﬂ ow rate.

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

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 oﬀ the 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 ﬂ exible tubing, connect the exposed end of the ﬁ rst 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 ﬁ rst active tube to be calibrated (clockwise to increase,

counterclockwise to decrease) until the calibrator indicates the method-speciﬁ ed ﬂ ow rate. Do not adjust the ﬂ ow rate on the pump. Note: For tri and quad models, ﬁ rst rotate each anti-tamper

cover to expose the ﬂ ow adjust screws, then adjust the appropriate one until the calibrator indicates the desired ﬂ ow (Figures 3 and 5).

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

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

Maintenance

Replace the Pump Inlet Filter

The AirChek 52 Sampler is ﬁ  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  ing (see right) and turn it counterclockwise to unthread it.

2. Holding the pump upside down, use a small ﬂ at-head 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  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.

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 ﬁ lter can decrease ba ery life.
