Battery Operation
Installing the Battery Pack
1. Carefully align the ba ery jack on the ba ery pack with the ba ery ter-
minal on the bo om of the pump base plate and push the ba ery pack
into place.
2. Insert and tighten two security screws
provided.
3. Charge ba ery completely before operating
pump (see Charging the Ba ery Pack).
Charging the Battery Pack
For optimum charge, ensure the pump is not
running while charger is a ached. To charge the
ba ery, orient plug on charging cable properly (see
caution and photo below). Insert the charging plug
from the charger into the ba ery charging jack on the
back of the pump. Plug the charger into a standard
wall outlet. The PowerFlex Charger will fully
recharge the ba ery in 6 to 8.5 hours (see Accessories
on page 30 for charger). Follow charger instructions.

Battery
Charging
Jack
Ensure proper orientation of charging cable plug before
inserting it into the charging jack. Improper orientation/contact
will short-circuit the battery. See photo at right. Note the keyed
side of the charging cable plug must mate with the keyed side
of the pump charging jack. Inserting the plug does not take
much force. If force is required, the plug is not properly oriented.
Short-circuiting the battery pack will render it immediately
inoperative.
After charging the battery pack, it is good practice to run the pump for approximately
fi ve minutes before calibrating. This ensures the battery is in more steady-state
conditions and improves the agreement in pre and post-sampling calibrations.
Do not charge or operate pump from charger in hazardous locations.
Use only SKC-approved charger designated for this model to ensure reliable
performance. Failure to do so voids any warranty.
Failure to follow warnings and cautions voids any warranty.
The battery pack may be kept on the SKC-approved charger for an indefi nite time.

Battery Operation
Battery Charge Level Indicator
Three bars indicate a full charge (normally appears a er charging),
approximately 75 to 100%.
Two bars indicate that the ba ery is charged enough to operate the
pump, approximately 25 to 75%.
One bar indicates ba ery charge is low (charge ba ery), approximately
1 to 25%.
Low Battery Fault
No bars and a fl ashing outline indicate a Low Ba ery Fault (pump
will go into HOLD, and then SLEEP mode in 10 seconds). Run time
data can be displayed by pressing any bu on. The pump will return
to SLEEP in 10 seconds. This may be repeated.
When the pump stops due to a low ba ery and is le to stand for a
period of time, one ba ery bar may appear. This false “recovery” will
fall quickly if the pump is operated without recharging it. RECHARGE
THE PUMP BEFORE SAMPLING.
Replacing the Battery Pack
Ba ery Replacement Notes:
• To retain pump history, ensure the pump has been allowed to go to
SLEEP a er the last run. Pump history will be lost if the ba ery pack or
AC power (ba ery eliminator) is removed while the pump is running.
SKC recommends that data be downloaded to a PC using DataTrac 2000
So ware prior to removal of the ba ery or power.
• Replacing the ba ery pack may erase scheduled runs programmed
with DataTrac 2000 So ware. A er replacing the ba ery pack, use
the so ware to reprogram the scheduled runs in the AirChek 2000
pump.
• Replacing the ba ery pack will erase sampling time, delayed start,
and other se ings entered using the pump keypad. Reset these pa-
rameters a er replacing the ba ery pack.
1. Release the ba ery pack by removing the two security screws located on
the bo om of the ba ery pack. Pull the ba ery pack away from the pump
body.

Battery Operation
2. Carefully align the ba ery jack on
the replacement ba ery pack with
the ba ery terminal on the bo om
of the pump base plate and push
the ba ery pack into place.
3. Replace and tighten the two
security screws removed in
Step 1.
Use of a repaired or rebuilt battery pack voids any warranty and the UL
Listing for intrinsic safety.
Do not charge or operate the pump from the charger in hazardous
locations!
Use only an SKC-approved charger and battery pack designed for the
AirChek 2000 Sample Pump to ensure reliable performance. Failure to do
so voids any warranty and the UL Listing for intrinsic safety.
Use of any device other than the approved battery pack to power the
pump voids the UL Listing for intrinsic safety and any warranty.
Failure to follow warnings and cautions voids any warranty.

Battery Eliminator
The Ba ery Eliminator is an accessory that converts alternating current (AC)
to direct current (DC) from which the pump can be operated for extended
runs. The Ba ery Eliminator should be used in non-hazardous locations
only. See page 30 for ordering.
To use the Ba ery Eliminator, the ba ery pack must be removed from the
pump (see Replacing the Ba ery Pack on page 6). The Ba ery Eliminator is
comprised of two pieces, (1) a wall cube that converts AC voltage to DC
voltage and (2) a power adapter that reduces DC voltage. The wall cube
fi ts into a standard wall outlet and its plug end is inserted into the power
adapter. The power adapter is fi ed on the pump in place of the ba ery
pack.
Use the battery eliminator to operate the pump in non-hazardous
locations only.
Use of the battery eliminator to power the pump voids the UL Listing
for intrinsic safety.
