11.4 Maintenance of components
11.4.1 Air filter for engine and compressor, service intervals
The air filters consist of filter housing with cover, filter cartridge, safety cartridge, indicator
and evacuation valve. Cleaning is carried out in two stages. The first stage comprises a
cyclone and the second stage a normal filter. Both cleaning stages take place in the filter
housing.
A filter's performance will improve right up until it becomes clogged. For this reason the fil-
ter cartridge should not be replaced at regular intervals, but only when it starts to become
clogged. The filter cartridges must never be cleaned as this impairs filtration and also risks
damaging the filter element.
There is an indicator fitted onto the filter housing to advise when the filter cartridge is
clogged. It is connected to the HEC display in the cabin, or the LCD display on the left-
hand side of the rig for cabinless rigs. A yellow warning symbol is visible on the status bar
at the bottom of the display if a filter starts clogging. The indicator must be checked every
1000th engine hour.
