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.
During “fast-charging,” the battery icon displays a solid outline
with three fl ashing bars.
During “trickle-charge” and upon receiving a full charge,
the battery icon is a solid outline with three solid bars.
A er charging the ba ery pack, it is good practice to run the pump for approximately fi ve minutes before calibrating. This ensures the ba ery 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 fi nished 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
indefi nite 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,
call SKC at 724-941-9701.
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 insuffi cient
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 fi xed 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 fi xed. 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 fl ow rate of 200 ml/min and back pressure of 10 inches of water. Pump
operation time will increase as fl ow 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
fl ashing. 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.
The battery will discharge during an extended run. However, when the charge
Note:
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.

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.
