FirstCheck+ 1000, 2000, 3000 & 5000
Statements
Responsibility For Use
FirstCheck+ instruments detect a large range of gases, which are potentially dangerous from both a
poisoning and/or an explosive perspective. FirstCheck+ instruments have many adjustable and selectable
features allowing the detector to be used in a variety of ways.
NOTE: Ion Science Ltd can accept no responsibility for the incorrect adjustment of features that cause harm
or damage to persons or property. FirstCheck+ can be used as a personal safety device. It is the user‟s
responsibility to respond appropriately to an alarm situation.
Inadequate performance of the gas detection equipment described in this manual may not necessarily be self-
evident and consequently equipment must be regularly inspected and maintained. Ion Science recommends that
personnel responsible for equipment use institute a regime of regular checks to ensure it performs within
calibration limits, and that a record be maintained which logs calibration check data. The equipment should be
used in accordance with this manual, and in compliance with local safety standards.
! WARNINGS !
1. For reasons of Intrinsic Safety, batteries MUST NOT be charged or replaced within potentially
flammable areas. Ensure you are in a SAFE area before carrying out any type of maintenance on
the FirstCheck+ instrument.
2. Substitution of components may impair intrinsic safety and result in unsafe conditions.
3. For safety reasons, the FirstCheck+ must only be operated and serviced by qualified personnel.
4. Please read and understand this User Manual fully before operating or servicing the FirstCheck+.
! CAUTIONS !
It is essential that the FirstCheck+ is always used with a supplied PTFE 0.45 micron filter fitted to the front
of the instrument. The FirstCheck+ internal pump draws over 200 ml/min of air into the instrument and
without a filter particles of debris and dust will be drawn into the cell inhibiting the correct function of the
instrument. These filters are consumable and should be changed after every 100 hours of use. The
frequency of replacement should be increased for dusty or moisture laden environments. Filters are available
for purchase from Ion Science; see our Accessories page for more information.
Users of instrumentation incorporating pellistor type flammable sensors should be aware that these sensors
are very susceptible to poisoning by silicones. Silicones are commonly used in aerosol cleaning products such
as furniture polish, in sealants, in furnishings, and in adhesives and adhesive labels. The culprit is often a
compound called hexamethyldisiloxane or HMDS for short.
A few parts per million in air for an hour or two causes serious permanent damage to the sensor, to the
extent that it will NOT work. Therefore any instrument such as Ion's Firstcheck+ should be kept well away
from facilities where silicones are used.
Quality Assurance
FirstCheck+ has been manufactured in compliance with ISO9001:2008, which ensures that the equipment
supplied to our customers has been designed and assembled reproducibly, from traceable components, and
leaves Ion Science calibrated to stated standards.
Disposal
Dispose of FirstCheck+, its components and any used batteries in accordance with all local and national
safety and environmental requirements. This includes the European WEEE (Waste Electrical and Electronic
Equipment) directive. Ion Science Ltd offers a take back service. Please contact us for more information. The
FirstCheck+ field case material is recyclable polypropylene.
Calibration Facility
Ion Science Ltd offers a calibration service including the issue of certification confirming calibration with
equipment traceable to UK national standards. A FirstCheck+ Calibration Kit is available from Ion Science to
allow a two-point calibration to be carried out in the field as a custom calibration, in order to maintain
traceability to national standards.
