Battery Installation/Charging
Battery Pack Charging System
The SKC Pocket Pump features the innovative “Smart Charging Battery System.”
The advanced technology of the battery pack’s circuitry provides multiple features:
• It allows the battery pack to regulate the charge it receives by reducing its fast
charge rate to a trickle charge rate when the battery is at maximum capacity thus
preventing damage to the battery.
• It is also designed to prevent harm to the battery by charging only if the battery
is within its acceptable charging temperature range of 40 to 100 F (5 to 38 C).
Outside of this range, the battery will only accept the low output trickle charge.
Charging the Battery Pack
Note: The initial charge of a new battery should be performed with the battery
detached from the pump. For installation after charging, see pages 4 and 5.
Ensure proper orientation of the charging cable before plugging it into the
charging jack. Improper orientation/contact will short-circuit the battery.
Short-circuiting the battery pack will render it immediately inoperative.
Battery detached: Plug the charger into a standard wall outlet and the charging plug
into the port on the battery pack. This type of charge is a slow trickle charge that is
recommended for the initial charge of a new battery pack. This charge will take approximately 16 hours to complete.
Battery attached: For a complete charge, ensure the pump is not running. Plug the
charger into a standard wall outlet and the charging plug into the battery port on the
bottom of the pump. The fast charging function of the battery pack will completely
recharge the battery in approximately six hours or less.
Š During “fast-charging,” the battery icon displays a solid outline
with three flashing bars.
Š During “trickle-charge” and upon receiving a full charge,
the battery icon is a solid outline with three solid bars.
After charging the battery pack, it is good practice to run the pump for approximately
five minutes before calibrating. This ensures the battery is in more steady-state
conditions and improves the agreement in pre and post-sampling calibrations.
See page 8 for Determining Battery Charge Levels.
Unplug the charging plug from the Pocket Pump battery port when finished charging
the battery pack. If the charger is unplugged from a wall outlet and the charging
plug is left in place, the battery charge will deplete.
Do not charge or operate the pump with the charger in hazardous locations.
Ensure the computer interface port is covered before, during, and after charging.
Failure to follow warnings and cautions voids any warranty.
Note:
The battery pack may be kept on the SKC-approved charger for an
indefinite time.

Battery Installation/Charging
Charging Fault
When the top bar is flashing and the bottom two bars are solid, a
charging fault has occurred. A charging fault may be caused by:
• Ambient temperatures that are out of charging temperature range
• A defective battery pack
• A disrupted charge cycle
To remove a charging fault, unplug the charger, allow the pump to equilibrate to
ambient temperature, and try to charge the battery again. If the icon display persists,
contact SKC Technical Support at [email protected]
FAIL Display
Symptom: Press [] from HOLD mode to RUN the pump. The pump will not run
and immediately goes back to HOLD mode.
Display: Press  to scroll through the display until FAIL appears.
Explanation: FAIL is a type of fault caused by battery capacity that is insufficient
to start the pump motor. This indicates a battery pack that has either developed a
fault or is at the end of its life. The fault cannot be fixed by recharging the failing
battery pack.
Solution: Remove the battery pack and replace with a new, fully charged battery
pack. Run the pump and scroll through the display. If the pump runs and FAIL is
not displayed, the fault is fixed. If FAIL still displays, there is a fault in the pump
electronics. Send the pump to SKC for repair.
Use only SKC-approved batteries to ensure reliable performance and intrinsic
safety.
Using a non-approved charger voids any warranty and could damage the pump
or battery.

Battery Installation/Charging
Determining Battery Charge Level
• The pump will operate for up to 12 hours with a NiMH battery (eight hours with
NiCad) at a flow rate of 200 ml/min and back pressure of 10 inches of water. Pump
operation time will increase as flow rate and back pressure rates are decreased.
• The LCD shows the current battery charge level. The icons appear as follows:
Three bars indicate a full charge (normally appear after charging), approximately
70 to 100%.
Two bars indicate that the battery is charged enough to operate the pump,
approximately 15 to 70%.
One bar indicates battery charge is low (charge battery), approximately less than
15%.
When the battery has lost all of its charge, all bars are clear and the outline is
flashing. The pump goes into HOLD mode and then to SLEEP mode in approximately one minute.
Extended Runs Using the Charger
Extended operation is possible in nonhazardous locations using the pump with its
battery charger plugged into a wall outlet.
Note: The battery will discharge during an extended run. However, when the charge
drops by 50%, the fast charge feature is initiated until the battery receives a full
charge. This cycle repeats every several hours during operation.
Do not charge or operate the pump with the charger in hazardous locations.
Use of any device other than the approved battery pack to power the pump voids
the UL Listing for intrinsic safety.

Operation
Calibrating and Sampling in Constant Flow Mode —
Multiple Tubes
For use with constant pressure controller and multi-port
adjustable low flow tube holders
The Constant Pressure Controller (CPC) (Cat. No. 224-26CPC-10) is a pump
accessory that provides a simple alternative for multiple sorbent tube sampling while
in Constant Flow mode. In conjunction with an Adjustable Low Flow Tube Holder
(Cat. No. 224-26-02, 224-26-03, or 224-26-04), the CPC is used as a pressure regulator
to maintain a constant 10 inches water back pressure. For multiple-tube applications
without a CPC, see Advanced Operation on page 21.
Calibration
Allow the pump to equilibrate after moving it from one temperature extreme to
another.
1.
Ensure the pump has run for five minutes before proceeding with calibration.
2.
Set the pump for Constant Flow mode (see pages 12 and 13) and set it to the
selected flow rate (see pages 15 and 16, Steps 5 through 12). Pump flow rate must
be set at ≥ 15% higher than the sum of the flow rates through all tubes.

reading (ins or mm). Record the back pressure for that tube. Press [] to place
the pump in HOLD.
8.
Repeat Steps 5 through 7 for each port to obtain the back pressure for each
representative tube.
All empty ports must contain unopened tubes during calibration and sampling.
When performing multiple-tube sampling in Constant Pressure mode, the flow
rate must be set as low as possible. The sum of the flow rates cannot exceed
100 ml/min for back pressures from 10 to 20 inches of water; the sum of the
flow rates cannot exceed 200 ml/min for calculated back pressures less than
10 inches of water.
21
Advanced Operation
9.
Obtain the calculated back pressure by adding one inch to the highest back pressure number and rounding up to the next number. The additional inch allows for
typical back pressure fluctuations.
Example using two tubes:
Tube

Back Pressure
(in H2O)
6.2
7.9
Calculated back pressure is 9 (7.9 + 1 = 8.9 rounded to 9).
10. Reinsert opened representative tube #1 back into port A. Place unopened tubes
in remaining port(s) to “seal” them.
11. Reset the pump to the desired flow rate for port A as done in Step 6.
12. While the pump is still in RUN, press  to scroll to Constant Pressure reading
(ins or mm). Use a screwdriver to turn the flow adjust screw clockwise for port A
on the Adjustable Low Flow Tube Holder until the display matches the calculated
back pressure. Press [] to place the pump in HOLD.
13. Repeat Steps 10 through 12 for remaining port(s).
14. Place the pump in Multiple Tube (Constant Pressure) mode. From RUN, press
[] to place the pump in HOLD,  (security code), and .
Pressing [] will place a running pump in HOLD and a holding pump in
RUN.
Do not charge or operate the pump with the charger in hazardous locations.
22
Advanced Operation
15. Set pump pressure to the calculated back pressure. From HOLD, press []
to RUN the pump, then enter  (security code) within 10 seconds.
The LCD will display the previously set back pressure, with flashing SET and
P indicators. The flow fault icon may also be flashing at this point.
16. Press  or  to increase or decrease the previously set back pressure setting until
it matches the calculated back pressure determined in Step 9. Press  to lock in
the pressure setting. The pump will return to its normal RUN state.
17. Reset the data display to zero (minutes that have elapsed during pump setup and/
or programming) before sampling by pressing [] to place pump in HOLD,
 to enter Setup, and .
18. Remove the representative tubes used for calibration and insert newly opened
tubes in their assigned ports. The pump is now ready to sample.
Sampling
1.
Press [] to RUN the pump and begin sampling.
2.
Press [] to HOLD the pump and stop sampling.
Run time data is retained in memory after sampling is completed. While the pump is
in HOLD mode, use the  button to scroll through run time data on the LCD.
3.
Remove and cap the tubes. Reconnect the calibration train to verify flow rate.
Use of any device other than the approved battery pack to power the pump
voids the UL Listing for intrinsic safety.
Protect the sample pump from weather when in use outdoors.
All empty ports must contain unopened tubes during calibration and sampling.

Pump Care
Pump Care
The Pocket Pump has been carefully designed, manufactured, and tested to provide
excellent performance. Proper care and maintenance include:
• Avoiding strong impacts
• Keeping the pump dry
• Not cleaning the pump with harsh cleaning solvents or detergents
• Storing the pump in a cool, dry, dust-free location
• If the sampling method used requires collection of the sample via the exhaust
port on the pump (sample passes through the pump such as bag sampling with
the twin port Pocket Pump), ensure that the sample air is dry and does not contain corrosive constituents. Failure to do so could lead to contamination of the
pump, degradation of performance, or failure of the pump. Failure to follow
this caution voids any warranty.
• Following instructions in the Battery Installation/Charging section to maximize
battery life
Use only SKC-approved parts to ensure reliable performance. Failure to do so
voids any warranty and the UL Listing for intrinsic safety.
The use of a repaired or rebuilt battery pack voids any warranty and the UL
Listing for intrinsic safety.
Failure to follow warnings and cautions voids any warranty.
