Attention:
The functioning of the entire series of filters is indispensible for proper filtration of the lube oil.
The automatic filter is the main filter and as such it has the finest filtration. It must therefore
only be bypassed in extreme emergencies.
3.4 Lube oil Automatic filter LF2 (with permanent oil flushing)
• Regular checking and cleaning of the gauze inserts (the differential pressure indication
shows the contamination level of the elements).
• Carefully check the filter elements for damage.
• If the filter has various cartridges, one damaged cartridge means a malfunction of the
entire filter. Renew damaged cartridges.
See the servicing instructions in the documents from the manufacturer.
3.5 Duplex lube oil filter LF1 (with indicator)
• Check the filter at regular intervals.
If required (differential pressure indicator shows 50 % of the red area or filter alarm),
carefully clean the isolated filter chamber, the filter cartridges being installed at working
temperature.
Remove the cartridges during every third cleaning.
• Renew damaged filter cartridges.
For servicing instructions see operating media A5.05.07.12.01.nn.
3.6 Strainer filter (for pumps)
• Clean the strainer filters in the suction pipes of the service and standby pumps every
6,000 operating hours and/or when work has been done on the suction side of the lube oil
piping system.
