IMPORTANT NOTE

Stratos-Micra is a very low maintenance detection system. If required, external cleaning
of the unit should be performed using a damp (not wet) cloth. Do not use solvents as
these may mar the front panel label. The only part that may require field replacement
during servicing is the dust separator assembly*. The dust separator condition can be
checked using the Dust Separator test in the Miscellaneous tab of the remote
software 'Detector settings' screen (see section 3.33) which gives a percentage
reading of dust separator efficiency. When this level drops to 80% the detector will
signal a fault and the dust separator will need replacing. To replace the filter, simply
remove the front cover and pull the filter out from the main unit. Slide the replacement
filter in so that the 'Direction of flow' arrow printed on the carton duplicates that on
the 'Direction of flow' label beside the filter slot.
*It is recommended that dust separators be changed at an interval of not more than
3 years. After replacing the filter, the detector must be put into FastLearn mode (see
section 3.7) to reset the filter condition reading.
As dust contained in the dust separators may expose maintenance personnel to a
'Nuisance Dust' hazard as defined by the 'Control of Substances Hazardous to Health'
(COSHH), it is strongly recommended that suitable masks and protective clothing be
worn when changing filters. Used separators are not intended for re-use and should be
disposed of.
