Turning Pump Power On/Off

• Turn on: Press and hold briefly the power on/off button on the side of the pump (see Figure 1). A startup screen will very briefly display all status indicators, followed by the firmware version (right) and then the set/verify flow screen or sampling screen showing elapsed time from a previous run. See Using the Operation Screens.
• Turn off: Press and hold briefly the power on/off button on the side of the pump (see Figure 1). Note: A non-running pump will shut off automatically after 60 seconds of inactivity but will hold the elapsed time from the last operation until the timer is reset.
  Note: The on/off button also locks and unlocks the touch pad and dims the screen during sampling. See Options/Modes during Sampling.

Determining Battery Charge Status
The battery status icon at the top right of the pump display screen has four bars that decrease in number as battery charge is depleted. See the table below to interpret the battery status.

Using the Touch Keypad
Lift the protective screen cover. Use your fingertip to touch the three keys on the screen keypad:

• Up and down arrows increase or decrease flow rate; during sampling, touching either arrow key briefly displays the relative flow indicator, described below. See Set/Verify Flow Screen for details.
• PUMP starts and pauses/stops pump; touch and hold to reset elapsed time.

Using the Operation Screens: Setting/Verifying Flow Rate and Sampling

• Set/Verify Flow Screen
  With pump connected to a flowmeter, touch and hold the up and down arrow keys on the touch keypad to increase or decrease flow rate (see below). Actual flow rate is displayed on flowmeter only.

• Relative Flow— A number between 1 and 99 that is relative to a flow rate and changes as flow is adjusted: 1 corresponds to the minimum and 99 to the maximum flow at which the pump can be set.
  Relative flow is different for each pump. In most cases, 10 ±5 will correspond to 1 L/min and 80 ± 5 will correspond to 5 L/min. Also displayed on the sampling screen when you touch the up or down arrow key during a run (if Screen Lock is not activated).

• Sampling Screen
  Note: The relative flow indicator is displayed in place of seconds on sampling screen when up or down arrow key is touched during sampling. Also displayed on set/verify flow screen. See Set/Verify Flow Screen for details.
  See Options/Modes during Sampling for details about the screen lock feature and flow fault mode.

• Reading Pump Status Indicators
  The status LEDs that bracket the screen display (see Figure 1) indicate pump status:

  • Green, flashing = Running
  • Red, flashing = Flow fault
    Note: Status LEDs will flash red/green to indicate that the pump is out of flow tolerance just before entering flow fault mode and during each auto- restart attempt while in flow fault mode

OPERATION

Setting/Verifying Flow Rate from 1 to 5 L/min

• Allow pump to equilibrate after moving it from one temperature extreme to another.
• Charge pump battery completely before flow rate verification and sampling.
• To achieve the best results, run the pump for 5 to 15 minutes before verifying flow rate.

1. Turn on the pump using the on/off button. If elapsed time from the last sampling run is still displayed, touch and hold the PUMP key on the screen touch keypad to return to the set/verify flow screen.
2. Prepare the flowmeter per flowmeter instructions.
3. Set up a flow rate verification train (Figure 3).
4. Using the up and down arrow keys on the pump set/verify flow screen, adjust flow until the flowmeter indicates the method-specified flow rate.
5. Touch the PUMP key to pause/stop the pump. The pump is now set to the selected flow rate.
6. Disconnect the pump from the representative sampling medium and flowmeter. Proceed to Sampling.

Setting/Verifying Flow Rate from 5 to 500 ml/min

• Allow pump to equilibrate after moving it from one temperature extreme to another.
• Charge pump battery completely before flow rate verification and sampling.
• Single-tube sampling requires All-in-One adjustable tube holder; see All-in-One operating instructions for details on operation.
• Multiple-tube sampling requires Constant Pressure Controller (CPC) and Dual, Tri, or Quad Adjustable Low Flow Tube Holder accessory; see CPC and Adjustable Low Flow Tube Holder operating instructions for details on operation.
• Verify pump flow rate before and after each sampling operation using the tube holder and pump to be used for sampling.
• To achieve the best results, run the pump for 5 to 15 minutes before flow rate verification.

Prepare the Sorbent Tube(s)

1. Determine the number and type of sorbent tubes needed for pre-sample flow rate verification and sampling.
2. Break tips off representative sorbent tubes for pre-sample flow rate verification.
3. If performing multiple-tube sampling, label tubes.

Prepare the Pump

1. Turn on the pump using the on/off button. If necessary, reset the timer by touching and holding PUMP on the screen touch keypad.
2. After preparing the flowmeter per flowmeter instructions, use flexible tubing to connect the flowmeter outlet (suction port) to the pump inlet.
3. Set pump flow rate using the up and down arrow keys on the set/verify flow screen to increase or decrease flow:
   • a. Single-tube sampling—1.5 L/min.
   • b. Multiple-tube sampling—the sum of all flows + 15%. Note: Do not exceed 500 ml/min flow rate per tube for multiple-tube sampling.
4. Disconnect the tubing from the pump inlet.

Prepare the All-in-One Adjustable Tube Holder (single-tube sampling)

1. On the tube holder, insert an opened representative tube (arrow on tube pointing toward the pump) into the rubber sleeve on the port. See Figure 4.
2. Use a small flat-head screwdriver to turn counterclockwise the brass flow adjust screw directly beneath the port.

Prepare the Dual, Tri, or Quad Adjustable Low Flow Tube Holder (multiple- tube sampling)

• On the tube holder, insert an opened representative tube (arrow on tube pointing toward the pump) into the rubber sleeve on the port. Repeat for the desired number of tube samples. See Figure 5. Place an unopened (inactive) tube in any unused port to “seal” it.
• Label ports on the adjustable tube holder to match the tube labels.
• Use a small flat-head screwdriver to turn counterclockwise the brass flow adjust screw directly beneath the port holding the first active tube for which flow rate will be verified.

Set Up the Flow Rate Verification Train
Set up the flow rate verification train as shown in Figures 4 and 5, connecting the flowmeter to the single sorbent tube or the first of multiple sorbent tubes.

Verify Pump Flow Rate with the All-in-One (single tube)

1. Using a small flat-head screwdriver, turn the flow adjust screw on the port clockwise to decrease flow or counterclockwise to increase flow until the method-specified flow rate is indicated on the flowmeter.
2. Once flow is verified for the tube, it is recommended practice to recheck it before removing the tube. Any adjustment should be minimal.
3. Disconnect the pump from the representative sampling medium and flowmeter. Proceed to Sampling.

Verify Pump Flow Rate with the Dual, Tri, or Quad Adjustable Low Flow Tube Holder
See appropriate adjustable low flow holder instructions.

1. Using a small flat-head screwdriver, turn the flow adjust screw on the first active port clockwise to decrease flow or counterclockwise to increase flow until the method-specified flow rate is indicated on the flowmeter.
2. Remove flowmeter tubing from the current tube and install it on the next active tube. Use a small flat-head screwdriver to turn counterclockwise the brass flow adjust screw directly beneath the port holding the tube for which flow is to be verified and repeat Step 1.
3. Repeat Steps 1 and 2 for each remaining active tube.
4. Once flow is verified for the tube, it is recommended practice to recheck it before removing the tube. Any adjustment should be minimal.
5. Disconnect the pump from the representative sampling medium and flowmeter. Proceed to Sampling.

Sampling

• Allow pump to equilibrate after moving it from one temperature extreme to another.
• Charge pump battery completely before flow rate verification and sampling.
• Use of any device (including charging cradle) or battery pack other than P75718 to power the pump voids intrinsic safety certifications and any warranty.
• Pump can be operated from cradle.
• If using sample tubes as media, verify pump flow rate before and after each sampling operation using the tube holder and pump used for sampling.

1. After setting and verifying flow rate, replace representative media with new, unexposed media for sample collection.
2. Set up the sampling train. See Figure 6.
3. Touch the PUMP key on the screen touch keypad to start sampling. Note: To lock screen during sampling, press pump on/off button (see Options/Modes During Sampling below).
4. Touch the PUMP key to stop sampling. Record run time and any other pertinent information. The elapsed time will flash on the screen.
5. Remove sample medium and cap it. Reinstall representative sample medium and perform post-sampling flow verification. See Setting/Verifying Flow Rate.
