5.3 Cleaning
The exterior of the analyser should be regularly cleaned using a slightly damp cloth. Remove
power before cleaning. Ventilation holes must be kept clear. Do not use solvents or abrasive
cleansers to clean the analyser.
5.4 Toxic/flammable samples - routine leak test
WARNING
If toxic and /or flammable samples are being analysed it is essential to check the
analyser and associated sample lines/system for leaks (every 6 months). MAX
pressure that may be applied to each module is 8psig (5psig for the 4900C), however,
this must be applied and removed slowly to both the inlet and outlet simultaneously
to avoid damage to the measuring sensors.
