14. Maintenance intervals
14.1. Usage-related maintenance
The described maintenances become necessary through the demands of the system operations. The
maintenance intervals are recommendations. Depending on the application (multi-shift operation, dust
generation, ...) it may make sense for the operator to change the intervals of maintenance, replacing
and cleaning.
Maintenance work must always be documented by means of a protocol.
The approach of the maintenance measures is described in chapter "Maintenance".
determined by the operator
Replacing the particle filter
The saturation of the particle filter is automatically monitored by
the filter unit and thus is not subject to a maintenance interval.
The filter unit triggers an alarm when a replacement of the
particle filter is necessary.
Replacing the activated carbon / the
activated carbon cassette (or check
the degree of pollution)
when odours occur /
when replacing the main filter
Replacing the prefilter mat
(or check the degree of pollution)
14.2. General maintenance
The described maintenances are independent from the demands of the system operations.
The operator is obliged to carry out repeated inspections and functional tests according to national
regulations. If not otherwise covered by national regulations, the described maintenance intervals must
be respected.
Maintenance work must always be documented by means of a protocol.
Visual inspection of the device
Functional test of the device
Electrical test of the electrical lines and earthing connections
