Description
SKC AirChek XR5000 Sample Pumps are designed to offer users enhanced battery
power and easy operation in a lightweight pump that provides accurate airfl ows from
5 to 5000 ml/min.
• Three battery options provide fl exibility and economy for different applications
including long run times.
• The large three-button keypad and straightforward user setup functions offer userfriendly conveniences.
AirChek XR5000 pumps feature a patented* isothermal fl ow sensor that measures fl ow
directly and acts as a secondary standard, constantly maintaining the set fl ow rate. A
built-in sensor compensates for changes in temperature that occur after calibration.

Charging the Lithium-Ion Battery Pack
For models containing a lithium-ion battery pack only.
Power
supply
Shown with single charger (Cat. No. 222-241). A
fi ve-station charger is available; see Accessories
on page 21. Follow charger instructions.
STOP!
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 selfdischarge during storage. Charge
Li-Ion pump battery completely
before calibration and sampling to
achieve optimum pump operation.

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

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 specifi c patterns. Observe the LED steadily for

Note
The battery pack may be kept on SKC-approved Li-Ion battery chargers for
an indefi nite time.
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
No. P85004 or P85002. Use of any other battery pack (including
alkaline) 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 fi re or high temperatures.
• Remove alkaline batteries from pump before storage to prevent damage from battery leakage.
• 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.
