8.2 Maintenance and remote maintenance
Maintenance consists of an inspection of the entire system and preventive checks as
well as cleaning the device. Check the possible ranges of consumables and look out for
signs of unusual damage which may have occurred since the installation and
commissioning work by following the steps described below. The regular maintenance
interval is one year. This monitoring work may be carried out more often to identify
discrepancies at an early stage.
TIP
Document all work completed, events which occur and general
operations in a maintenance report.
CAUTION
The regulations for explosion protection (for example IEC/EN 60079-14)
must be followed to the letter. In addition, the operator must check the
function of all safety devices regularly, even outside the maintenance
interval if necessary.
The best thing for cleaning the device is a damp cloth with a mild detergent solution or
a mild cleaner such as those used for household purposes.
CAUTION
•
Do not use any equipment for cleaning which charges statically
and may generate sparks.
•
Do not pour or spray water or cleaning products directly into the
breather valve or vent line.
•
Do not use high-pressure cleaners or similar equipment for
cleaning
CAUTION
•
If the device is installed in a potentially explosive atmosphere,
compliance with the explosion protection regulations is also
mandatory.
•
Furthermore, the operator must check all safety devices at regular
intervals, possibly independently of the maintenance work, to
ensure that it all functions correctly.
