Required Equipment

• 1/4-inch ID (3/8-inch OD) Tygon® tubing
• Charger for Li-Ion battery-powered pump
• Low flow accessories if sampling at 5 to 500 ml/min. See Accessories.

Getting Started

Charge the Lithium-Ion Battery Pack

• Completely charge a new battery pack before operating the pump. It may be necessary to charge the battery a few times before maximum battery capacity is achieved.
• Intrinsic safety circuitry inside the battery causes the pump to self discharge during storage. Charge battery completely before calibration and sampling to achieve optimum pump operation.
• After charging the battery pack, it is good practice to run the pump for approximately 5 minutes before calibrating. This ensures the battery is in more steady-state conditions and improves the agreement in pre and post-sampling calibrations.
• The battery pack may be kept on SKC-approved Li-Ion battery chargers for an indefinite time.

1. For a complete charge, ensure the pump is not running. Insert plug on charging unit into the battery charging jack on back of pump. Ensure plug is oriented so that the arrow on the plug is facing upward.
    Ensure proper orientation of charging cable before plugging it into the charging jack.
   Improper orientation/contact will short circuit the battery and voids any warranty.
     Short circuiting the battery pack will render it immediately inoperative.

2. Insert plug on power supply into jack on charging unit.

3. Pull locking tab to side and insert appropriate wall plug into power supply.
   Release locking tab. Plug power supply into a wall outlet.

4. The standard 2-cell Li-Ion battery pack will recharge in approximately 4 hours. The high-power 4-cell Li-Ion battery pack will recharge in approximately 8 hours. Run pump for 5 minutes after charging is complete.

Reading the Charging Status LED on the Single Charger

The Li-Ion Charging Unit (Cat. No. P22300) indicates battery charge status via an LED on the unit that blinks in specific patterns.
Observe the LED steadily for > 5 seconds to read charge status (see below).

Determining Battery Charge

Three bars indicate a full charge (normally appears after charging), approximately 75 to 100%.
Two bars indicate the battery is charged enough to operate the pump, approximately 25 to 75%.
One bar indicates battery charge is low (charge battery), approximately 1 to 25%.
No bars indicate that low battery fault is imminent.
Low Battery Fault
No bars and a flashing outline indicate a low battery fault (pump will go into Hold and go to sleep after 15 seconds in low battery fault).
Accumulated run time will be retained.

Notes and Cautions

• Do not charge or operate pump from charger in hazardous locations.
• Use only the charger and battery packs designed for the AirChek XR5000 pump to ensure reliable performance. Failure to do so will void any warranty.
• For safe operation in hazardous locations, ensure the pump label contains the logo and the battery pack label contains Cat. No. P85004 or P85002. Use of any other battery pack or device to power the pump voids the UL Listing for intrinsic safety.
• Tampering with the battery pack or using a repaired or rebuilt battery pack voids any warranty and UL Listing for intrinsic safety.
• Do not open, disassemble, short circuit, crush, incinerate, or expose the battery to fire or high temperatures.
• Use only the SKC-approved charger for this pump. Use of an unapproved charger may damage the battery and pump and voids any warranty.
• Failure to follow warnings and cautions voids any warranty

Operation

High Flow Applications (1 to 5 L/min)

Set/Calibrate Flow Rate

Allow pump to equilibrate after moving it from one temperature extreme to another.
Charge pump battery completely before calibration and sampling.

1. Ensure that battery is fully charged and that pump has run for 5 minutes before calibrating.

2. Prepare the calibrator. See calibrator instructions.

3. Set up a calibration train (see above): Using flexible tubing, connect the calibrator outlet (suction port) to the representative sample medium inlet. Using 1/4-inch Tygon tubing, connect the sample medium outlet to the pump inlet.

4. With pump in a non-running state (no flashing blue LED), set the desired pump flow rate as follows:
   a. Press ▲▼   to enter user setup functions.
   b. Press until “ADJ” and “Flow” flash on display. Press ▲ to increase flow. Press ▼ to decrease flow (dashed lines will move up or down on the display to indicate graphically the direction of the adjustment) until the calibrator indicates the method-specified flow rate. Flow rate will not display on pump LCD. Observe the calibrator to determine flow rate. Once the desired flow rate is indicated on the calibrator (within ± 5%), press [▲▼] to accept flow setting and to exit user setup functions. Take a minimum of three readings and record the average flow rate, as per OSHA/NIOSH instructions. The pump is ready to run.

   • Changing the flow rate in user setup functions will not clear accumulated run time.
   • Changing the timed run and/or run delay settings in user setup functions will automatically clear accumulated run time.

5. 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.
• Use of any device or battery pack other than Cat. Nos. P85004/P85004A and P85002/P85002A to power the pump voids the UL Listing for intrinsic safety.
• Charge pump battery completely before calibration and sampling.

1. Replace sample medium with new unexposed medium for sample collection.

2. Place the sample medium where appropriate for sampling. 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, place an in-line trap 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.

3. Start a continuous or timed sample run by pressing [▲▼]. Record start time and other pertinent information.

   • Sampling will start automatically if a run delay is set and initiated. Sampling will stop automatically if a timed run is set and initiated.
   • For automatic start and stop, set and initiate both a run delay and a timed run.

4. Sample for the time specified in the method used. Accumulated run time will display on the LCD.

5. To stop a sample run, press [▲▼]. This places the pump in Hold. Record stop time and other pertinent
   information.
   a. To resume sample run without clearing accumulated run time, press [▲▼].
   b. To clear accumulated run time, place pump in Hold, press ▲▼   to enter user setup functions, and press [▲▼] when CLr displays.
   Possible Displays During Sampling
   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 fault icon displays on the LCD and flashes during the length of the fault, the pump enters Hold mode, and the accumulated run time display is retained. The pump will restart in 15 seconds and try to continue sampling. If the flow remains restricted, the pump will return to flow fault. Auto- restart is attempted every 15 seconds up to 5 times. Flow fault time is not added to accumulated run time.

To clear a flow fault and the flow fault icon, determine the cause of the fault, remedy the fault cause, and press [▲▼] to remove the icon from the LCD and restart the pump.
Note: A low battery fault may occur instead of a flow fault when there is a low battery charge at the time of the fault, excessive back pressure, and/or when there is a very short distance between the restriction and the pump inlet (e.g., finger fault versus pinched tubing).
The flow fault icon will not appear and auto-restart will not be activated under these conditions. A low battery fault icon will appear instead and the pump will go to Sleep.
If pump goes to Sleep while in flow fault, the flow fault icon may remain displayed on the LCD when the pump is subsequently turned on. To remove the icon from the LCD, place the pump in Hold, press ▲▼   to enter user setup functions, and press [▲▼] when “CLr” appears.

6. Cap the sample and send it with blanks and pertinent sampling information to a laboratory for analysis.
7. Verify the flow.
   a. Turn on the pump and reinstate the calibration train and sampling 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 adjustable tube 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 Adjustable Tube Holder

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.
• The flow rate through the pump is set first and then the flow rate through the sorbent tube is calibrated.
• 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 battery is fully charged and that pump has run for 5 minutes before calibrating.

2. Prepare the calibrator (see calibrator instructions). Using flexible tubing, connect the calibrator outlet (suction port) to the pump inlet.

3. With the pump in a non-running state (no flashing blue LED), set the pump flow rate to 1.5 L/min as follows:
   a. Press ▲▼   to enter user setup functions.
   b. Press until “ADJ” and “Flow” flash on display. Press ▲ to increase flow. Press ▼ to decrease flow (dashed lines will move up or down on the display to indicate graphically the direction of the adjustment) until calibrator indicates the method-specified flow rate. Flow rate will not display on pump LCD. Observe the calibrator to determine flow rate. Once the desired flow rate is indicated on the calibrator (within ± 5%), press [▲▼] to accept flow setting and to exit user setup functions.
   Take a minimum of three readings and record the average flow rate as per OSHA/NIOSH instructions.

   • Changing the flow rate in user setup functions will not clear accumulated run time.
   • Changing the timed run and/or run delay settings in user setup functions will automatically clear accumulated run time.

4. Remove tubing from the pump inlet.

Flow Rate Through Sorbent Tube

1. Attach the Tygon tubing from the All-in-One to the pump inlet. See right. Break tips off the representative sorbent tube and insert it into the rubber sleeve on the holder (arrow on tube pointing toward pump). Ensure that the sorbent tube fits snugly in the rubber sleeve prior to sampling to avoid any air leakage. Two sleeves, each a different inner diameter, are supplied with the All-in-One.
   If the pump flow faults shortly after attaching the tube holder, check that the needle valve on the All-in-One is open by using a small flat-head screwdriver to turn the flow adjust screw on the holder slightly counterclockwise. If the flow fault continues, check that the two small holes on the bottom of the built-in CPC are not blocked.

2. Using flexible tubing, connect the exposed end of the sorbent tube to the calibrator outlet (suction port).

3. Adjust the flow rate through the sorbent tube using a small flat head screwdriver to turn the flow adjust screw on the holder (see right) counterclockwise to increase flow or clockwise to decrease flow until the calibrator indicates the method-specified flow rate. Do not adjust flow rate on the pump.
   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. When calibration is complete, disconnect the calibrator and tubing from the sorbent tube inlet.

Maintenance

Notes and Cautions

• For safe operation in hazardous locations, ensure the pump label contains the logo and the battery pack label contains Cat. No. P85004/ P85004A or P85002/P85002A. Use of any other battery pack or device to power the pump voids the UL Listing for intrinsic safety.
• Do not charge or operate pump from charger in hazardous locations.
• Use only the charger and battery packs designed for the AirChek XR5000 pump to ensure reliable performance. Failure to do so voids any warranty.
• Use only SKC-approved parts to ensure reliable performance and to maintain the UL Listing for intrinsic safety. Failure to do so voids any warranty.
• Tampering with the battery pack or using a repaired or rebuilt battery pack voids any warranty and UL Listing for intrinsic safety.
• Do not open, disassemble, short circuit, crush, incinerate, or expose the battery to fire or high temperatures.
• Use only the SKC-approved charger for this pump. Use of an unapproved charger may damage the battery and pump and voids any warranty.
• Failure to follow warnings and cautions voids any warranty.

Replace the Li-Ion Battery Pack

• To retain display data, ensure pump is placed in Hold before disconnecting the battery pack. Display data will not be retained if battery is removed while pump is running.
• Completely charge a new battery pack before operating the pump.
• It may be necessary to charge the battery a few times before achieving maximum battery capacity.
• If the pump does not operate as expected after replacing the battery pack, see Reset Pump to Manufacturer Settings.

1. Place pump in Hold (no flashing blue LED).
2. Release the battery pack by removing the two screws on the bottom of the battery pack housing.
3. Pull the battery pack housing away from the pump case.
4. Align the pump case with the new battery pack. The etched SKC logo should be on the same side as the LCD and keypad. Press the two parts together until snug. The pump will power up and the LCD will display the last mode used (typically Hold) and possibly accumulated run time from the last sample run.
5. Replace the two screws on the bottom of the battery pack housing and use a Phillips head screwdriver to tighten them in an alternating fashion.
6. Charge the new battery pack completely before use. See Charge the Lithium-Ion Battery Pack.

See www.skcinc.com/knowledgecenter for more information on SKC pump lithium-ion (Li-Ion) battery packs.

Reset Pump to Manufacturer Settings

If the pump does not operate as expected, perform the following procedure:

1. Remove the battery pack. See Replace the Li-Ion Battery Pack.

2. On the pump keypad, press and hold and ▼ simultaneously while attaching the pump to the new battery pack. The LCD should display the software version number (525X).
   Do not release hold on the two keys until the pump is firmly attached to the battery pack.

3. Release ▼ and . The LCD should display number between 170 and 210.

4. Press one time. The LCD should display number between 70 and 90.

5. Press ▲ and ▼ simultaneously. Pump should be in HOLD or start. Repeat Steps 1 through 5 if needed.

6. Install the two screws on the bottom of the battery pack housing and use a Phillips head screwdriver to tighten them in an alternating fashion.

Pump Service
