2) Care of Universal MTX Series Pumps
• Always use the correct SKC batteries and battery chargers designated for the Universal 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.
• When carrying out sampling using impingers always fit a trap between the impinger and pump inlet. This will
prevent the possibility of the fluid used in the impinger from entering and damaging the pump mechanism. As a
further precaution always ensure that the pump flow rate is set to below 1 litre/min before connecting the trap and
impinger to the pump inlet. For stability use the accessory mounting screws (refer to pump diagram on pages 8
and 9) to fix the impinger bracket to the front of the pump.
• The Universal 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.
• Universal 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. P2240901).
Warning - Failure to follow these guidelines will void the product warranty.
