4 MAINTENANCE AND TROUBLE SHOOTING
4.1 Maintenance
The Axetris LGD Compact gas sensor modules will not require routine maintenance when the installation and
operation instructions described in this document are carefully applied. The surface of the instrument can be
cleaned with a soft tissue and the use of isopropyl alcohol. Any gas filtration and conditioning equipment must
be checked and replaced periodically according to manufacturer specifications.
If the measurement cell gets contaminated or damaged, please contact Axetris for cell maintenance and
replacements. As technical training is necessary for this procedure, we recommend setting up a system
exchange program. Please contact Axetris for details.
In case of problems, re-check all the recommendations presented in this document and be sure they have
been followed and fully applied. If the observed problems persist, contact your Axetris sales person.
It is important that this device is serviced only by adequately trained and qualified personnel.
This instrument contains electronic components that might be damaged by static electricity. The
device cover should never be removed as it might damage the optics and/or electronics.
Axetris gas sensor modules contain metal and elastomeric sealing parts. The customer is responsible
for checking the compatibility of those materials with the gas applied to the device. Not observing
these recommendations might lead to personal injury or death.
It is recommended that the user checks the device regularly to ensure that it is leak-free. Sealings may
change their characteristics with age, exposure to process gas, temperature and pressure.
If it is necessary to remove the device from the system, unplug the electrical power before any other
manipulation.
Before removing the device from the system, purge thoroughly with a dry inert gas such as Nitrogen
before disconnecting the gas fittings. Ensure that the piping is de-pressurized. Failure to correctly
purge and de-pressurize the device could result in fire, explosion, or severe injury.
