Maintenance
BOGE Operating instructions for S 40-2...S 341 / SF 40-2...SF 220 series screw compressors
Fig. 5.8: Changing the oil filter Note:
Changing
the oil separator
Change: – When the difference between supply and system pressure
exceeds 12 psig.
– When warning message "8" appears on the control system
display (if option is installed).
– After 3000 operating hours,
however, no later than after one year.
NOTICE:
If the specified maintenance intervals are not observed, the oil separa-
tors might become blocked. In this case, the differential pressure will
increase until the safety valve blows.
– Switch off the compressor using the OFF button.
DANGER: Risk of injury!
Switch off the main switch and secure it against unintentional switch-on.
– Close ball valve at the compressed air outlet.
– Open safety sound insulation hood.
– Vent the compressor (as described in the beginning of the chapter).
The system pressure gauge must indicate a pressure of 0 psig.
– Wait approx. 3 minutes to permit the oil to settle.
