8. Routine Maintenance
The equipment is designed to keep the levels of maintenance to an absolute minimum.
8.1. Cleaning Windows
It is important that the windows at the transducers remain reasonably clean. They may be cleaned, by removing
the transducer from the air purge, (by removing the three M6 socket head screws) and cleaning each window
with a clean soft dry cloth.
Clean the internal surfaces of the mounting tubes to remove any build-up of dust or ash.
It is estimated that window cleaning should be required every 6 months. However, this interval will depend
entirely on the operating conditions and the dirtier these are the more frequently cleaning may be required.
On positive-pressure ducts ensure that precautions are taken prior to removal of the transducers
for lens cleaning
– failure to do so could result in maintenance personnel being exposed to
dangerous, hot, toxic gases.
