1. Start the pump using the on/off switch (Figure 1), and adjust the flow rate by turning the flow adjustment
screw (Figure 1) until the built-in rotameter reads approximately 1.5 L/min.
2. Remove the cap screw covering the regulator valve (Figure 1) and turn the exposed screw four to five turns
counterclockwise.
3. Replace the cap screw. The pump is now set for low flow.
Set/Calibrate Flow Rate for Multiple Tubes
• 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.
Follow these important steps before proceeding:
1. Ensure that the battery is fully charged and that the pump has run for five minutes before calibrating. Leave pump running.
2. Ensure that the regulator has been activated for low flow and the pump flow rate is set at 1.5 L/min.
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.)
* Back pressure across some sample tubes can be higher than average. In these instances, the maximum flow rate of 500 ml/min may not be achieved.
4. Connect the adjustable tube holder (Figure 4) to the pump inlet (Figure 1) using the attached 1/4-
inch Tygon tubing. See right.
5. Insert an opened sorbent tube into each rubber sleeve of the tube holder (Figure 4). Ensure that
the arrow on each tube points toward the tube holder.
If sampling with fewer tubes than number of ports, insert unopened sorbent tubes in the empty
ports to seal them.
For low flow, turn regulator
valve screw counterclockwise.

6. Prepare the calibrator. See calibrator instructions.
7. Using flexible tubing, connect the exposed end of the first sorbent tube to the calibrator outlet (suction port). Loosen and turn the brass
flow adjust screw (Figure 4) on the port of the appropriate tube holder (counterclockwise to increase, clockwise to decrease) until
the desired flow rate is achieved. Note: For tri and quad models, first rotate each anti-tamper cover (Figures 4 and 5) to expose the flow adjust
screws, then adjust the appropriate one until the calibrator indicates the desired flow.
Do not adjust the flow on the pump. Adjust the flow only by using the flow adjust screw on the
tube holder.
Do not exceed 500 ml/min flow rate per tube.
8. Disconnect the calibrator from the tube and connect it to the next sorbent tube. Repeat the flow adjustment
process until all tubes are flow-calibrated. Changing the flow on one tube will not affect the flow rate
through the remaining tubes.
9. When the flow rate is set for each tube, turn off the pump and disconnect the calibrator.
