Notes
1. In very dusty surroundings it may be necessary to check and replace the air filters more frequently. Consult Atlas Copco.
2. Use Atlas Copco filters.
3. The separator element must be replaced two-yearly or each 8000 running hours or when the pressure difference over the
element exceeds 0.8 bar. Check the pressure drop when the compressor is running loaded and preferably with a stable
working pressure.
4. Any leak should be attended to immediately.
5. Damaged flexibles must be replaced immediately.
6. See "User manual for Elektronikon regulator", section "Submenu TEST".
7. To be carried out by an Atlas Copco Service representative.

9. If necessary, empty the collector and deliver the oil to the local oil collection service. Keep the cover of the vessel installed
to prevent possible evaporation.
10. Stop the compressor, close the outlet valve, open the valve underneath the condensate trap, fill the new filter with water and
fit it. Inspect the strainer/restrictor at the inlet of the separator vessel, clean and reinstall it. Close the valve underneath the
condensate trap.
