2) Care of Pocket Pump MTX Series Pumps

• Always use the correct SKC battery pack and battery chargers designated for the Pocket Pump MTX series
pumps.

• Never run the pump long term without a tube or filter medium in place.

• When carrying out sampling using long term colour change tubes always use a tandem tube holder with trap tube

(Part No. 222-3D-2 and cover 224-29T). This will prevent the aggressive fumes generated by these tubes from
entering and damaging the pump mechanism.

• The Pocket Pump MTX series pump cases are IP20 rated, they are not rated as water or splashproof and
therefore must not be used where it is possible for water to enter the pump casing.

• Pocket Pump MTX series pumps are fitted with a particulate filter which is easy to replace. For general maintenance
replace the filter every 2-3 months or if it appears dirty. New filters are white in colour (order Part No. P40010).

• If the sampling methodology to be used requires the collection of the sample from the outlet of the pump (210­1003MTX twin port model only), i.e. the sample is passing through the pump mechanism, ensure that the sample
air is dry and does not contain corrosive constituents. Failure to do so could lead to contamination of the pump
mechanism, degradation of performance or even failure of the pump.

Warning - Failure to follow these guidelines will void the product warranty.

Getting Started

1) Charging the Battery Pack

Prior to first use the battery pack should be fully charged, ideally overnight.

The Pocket Pump MTX series pumps must only be charged using the correct SKC chargers (Part Nos. 223­229A - single charger, 223-107A - five station charger).

The chargers are supplied with mains input plugs suitable for use in the UK, Europe, USA and Australia / New
Zealand. Select the correct mains input plug and fit it to the charger.

Plug the charger output jack plug into the mating socket at the base of the pump. Plug the charger into the
electrical mains supply and switch on the power. The LED indicator on the charger will illuminate to indicate
that the battery pack is connected.

The battery status icon on the pump LCD screen will flash to indicate that charging is taking place. Depending
on the charge state of the battery at the start of charging it will take up to six hours to fully charge the
battery. The Pocket Pump includes an intelligent charging circuit which detects when the battery pack is fully
charged, therefore charging may complete in less than six hours. When full charge has been detected the
pump automatically switches to a trickle charging mode.

At the end of charging the battery status icon will be on (not flashing) and showing three bars to indicate full
charge. If the battery icon remains flashing after six hours, this indicates a charging error. It is recommended
to disconnect and reconnect the charger, and if this condition persists after a further six hours of charging,
it would indicate a fault with the battery pack or charger. Contact SKC Limited customer services for further
advice.

When fully charged disconnect the charger jack plug from the battery pack.

The pump run-time data is recorded during the flow rate setting and calibration
operations. Before starting a sample run reset the run-time data.

3) Multiple Tube Sampling in Constant Flow Mode Using a Constant Pressure Controller

An alternative method to Constant Pressure mode for multiple tube sampling is to use a Constant Pressure
Controller (CPC - SKC Part No. 224-26CPC-10). The CPC is a device that generates a constant back pressure
of 10 inches of water at the outlet of the connected multiple tube holder.

Ensure that the pump is set to Constant Flow mode and set the pump flow rate to a level higher than the
combined flow rates through the tubes. The pump flow rate does not need to be accurately calibrated.

Connect the CPC between the pump air inlet port and the multiple tube holder. The short length of tubing
supplied with the CPC is connected to the pump and the multiple tube holder is connected to the side of the
CPC marked “TO SAMPLE”.

The flow rate through the individual tubes can then be calibrated using the needle valves built into the multiple
tube holder.

www.skcltd.com 210-PMTXM Issue F Page 17

Operating the Pocket Pump in Constant Pressure Mode

Constant Pressure mode provides built in constant pressure control for multiple tube sampling applications.

It is recommended to start with a pump back pressure setting of 10 inches of water. Once the pump back
pressure is set, the tube flow rates are set using the needle valves built into the multiple tube holder. If it is not
possible to set the flow through a given tube high enough, then increase the pump back pressure setting, until
the required flow rate can be acheived.

Note that the combined flow rate through all of the tubes should not exceed 200 ml/min, and the pump back
pressure setting should not exceed 20 inches of water. Before starting sampling check that the pump can run
for the required sample duration at the combined flow rate and back pressure.

Constant Pressure mode is indicated by a ‘

2) Constant pressure mode sampling

With the Pocket Pump set to constant pressure mode it is possible to obtain a stable pump flow rate with
variable outlet back pressures (up to 30 inches of water). An adjustable flow restrictor at the pump inlet is
required to set the desired flow rate. Note that once the required flow rate has been set, the sample train inlet
flow restriction must remain constant during sampling.

Constant pressure mode compensation performance: With a constant inlet restriction of 5 inches of
water, the pump flow rate will be within ±5% with outlet back pressure of 30 inches of water up 100 ml/min
flow rate, and with outlet back pressure of 20 inches of water up to 200 ml/min flow rate.

To set the pump up for constant pressure mode through flow sampling applications:

• Use only SKC approved charger designated for this battery pack. Use of a non-SKC approved charger

may impair battery performance or even cause irrepairable damage, and will invalidate the battery pack
warranty.

Battery Performance

• Charging temperature - For optimum performance charge NiMH batteries between 0 and +40°C.

• Do not overcharge - For optimum performance disconnect battery pack from charger after 24 hours.

• Discharge temperature - For optimum performance discharge NiMH batteries between -10 and +45°C

(refer also to pump specifications on page 3 for other limitations on operating temperature for intrinsically
safe applications).

Battery Maintenance

• Battery cycling during regular use - To maintain optimum capacity during regular battery use, cycle battery
once a month. Run pump until low battery shutdown occurs, then fully charge battery.

• Long term storage and highly infrequent use -

1. Charge battery fully prior to long term storage.

2. Store in a cool, dry place at temperature between 0 and 30°C.

3. Recharge battery at least once a year (or more frequently if stored at temperature above 30°C).

4. Cycle battery 2 to 3 times after long term storage to restore optimum capacity.

Care of the Battery Pack

Battery Testing

1. Connect SKC approved charger to battery pack. If charger indicator LED illuminates, battery pack charger
input is ok. If charger LED does not illuminate, battery pack input fuse is blown - Replace battery pack.

2. Leave battery pack connected to charger to fully charge.

3. If pump does not function at all after full charge of battery pack, battery pack output fuse has blown, or
battery cells have failed or are at end of life - Replace battery pack.

4. If pump functions after full charge of battery pack but gives significantly reduced run times before low
battery shutdown, battery cells are failing or are at end of life - Replace battery pack.

Battery Replacement

Refer to the pump component diagram on page 28. To remove the battery pack slide down and remove the
slide cover. Unfasten the two screws revealed beneath the slide cover. Unfasten the screw that secures the belt
clip and remove the belt clip and rear case, to reveal the battery pack. Carefully pull the battery pack upwards
out of the pump case.

Fit the replacement battery pack, taking care to ensure that the battery connector engages with the pins of the
connector on the pump PCB. Re-assemble the pump case in the reverse of the above procedure. Charge the
new battery pack fully before use.

Battery Disposal

• The EC Battery Directive and equivalent legislation in other countries requires that all batteries and battery
packs are disposed of correctly at the end of their working life. This means that they must be collected and
treated separately from other waste.

• Please ensure that any end-of-life SKC battery packs are collected and recycled or disposed of correctly.

Pocket Pump DataTrac Software

With the optional DataTrac Software accessory, the Pocket Pump is programmable using a PC. DataTrac
simplifies chain-of-custody reporting by allowing users the option of programming a complete running
sequence, delayed start, timed stop, and intermittent sampling, all at different flow rates. Time and sample
volume are continuously updated in memory. There is no need to perform lengthy calculations; DataTrac does
it for you. The advanced information retrieval system is specifically designed to store data and provide chain­of-custody information. Fault features allow storage of historical data in memory that can be retrieved up to 24
hours after shutdown. The full DataTrac user’s manual is included on the software CDROM.
