Pump Features
Battery charging options
SKC offer two battery charger options for the Pocket Pump MTX series pumps, a single
charger (Part No. 223-229A) and a five station charger (Part No. 223-107A). When the
battery pack is fitted into the pump, a fast charge mode is enabled providing a charge
time of up to 6 hours. If the battery is charged external to the pump then the charge time
will be up to 16 hours.
Mains power option
The 223-229A single charger model can also be used as a mains adaptor to run the
pump for indefinite periods whilst connected to the electrical mains supply. Note that it is
recommended to ensure that the battery is fully charged prior to commencing sampling.
Warning - The pump must not be used in potentially explosive areas when the
charger is connected.
Keypad cover
The pump controls are situated beneath a sliding cover to prevent accidental actuation of
the keypad during a sample run.
LCD screen LCD screen indicates run-time data, operating and fault modes and battery charge state.
Constant flow mode Provides compensated constant flow control for single tube sampling applications.
Constant pressure mode Provides constant pressure control for multiple tube sampling applications.
Sample hold function Enables pausing and restarting of the pump during a sample.
Low battery shutdown
Automatic pump shutdown in the event of a low battery condition. The low battery shutoff
voltage is selected to prevent over-discharge of the battery which can cause degradation
of the battery performance. The pump retains the run-time data in the event of a low
battery shutdown.

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. 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
The Pocket Pump MTX series pumps incorporate an intelligent charging function that monitors the battery pack
during charging and automatically switches to a trickle charging rate when the battery pack is fully charged to prevent
damage due to over-charging. A full charge will take up to 6 hours dependent on the charge state of the battery
pack at the start of charging. The charging function also includes a feature that enables full charge rate only when
the battery pack temperature is within the range +5 to +38°C. When the temperature is outside this range only trickle
charging rate is enabled.
Pocket Pump battery packs can also be charged when not fitted to the pump. In this case charging occurs only at the
trickle charging rate and a full charge will take up to 24 hours.
Use only the correct SKC chargers (Part Nos. 223-229A - 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.
Prior to first use the battery pack should be fully charged, ideally overnight. It will take 2 – 3 full charge / discharge
cycles for the battery pack to achieve optimum capacity. If a new battery pack repeatedly exhibits a charging fault as
detailed below it is recommended to condition the battery pack by running the pump until it shuts down due to low
battery, then remove the battery pack from the pump and charge for 24 hours.
To charge the battery pack select the correct mains input plug and fit it to the charger. Plug the charger into the
electrical mains supply and switch on the power. Plug the charger output jack plug into the mating socket at the base
of the pump. The LED indicator on the charger will illuminate to indicate that the battery pack is connected.
During charging all three bars of the battery status icon on the pump LCD screen will flash. 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 shows one flashing bar at the end of charging, this indicates a charging fault. It is recommended to
disconnect the charger, wait for the battery pack temperature to stabilise to the ambient temperature then reconnect
the charger. If the charging fault condition re-occurs this would indicate a fault with the pump, battery pack or charger.
Contact SKC Limited customer services for further advice.

When fully charged disconnect the charger jack plug from the battery pack.
2) Battery Status Indicator
The battery status indicator on the pump LCD screen shows the current battery charge level:
Fully charged. 3 bars displayed from approximately 100% to 75% capacity. Note: It is strongly
recommended to ensure that the battery is fully charged before starting a sample run.
2 bars displayed from approximately 75% to 25% capacity.
1 bar displayed below approximately 25% capacity.
Low battery. No bars and flashing outline indicates low battery. Pump automatically switches to
HOLD mode, and then SLEEP mode after 1 minute.
Battery charging. When the battery charger is connected, the battery status indicator flashes all 3
bars to indicate charging. At the end of charging the battery status indicator will stop flashing and
show 3 bars continuously.
Battery charging error. Bottom 2 bars showing continuously and top bar flashing at the end of
charging indicates a charging fault. Refer to text on page 10.
