Atlas Copco Oxygen Generator OGP 2

Safety Precautions: Close the generator's outlet valve and the air inlet valve and wait until machine working pressure is 0 bar. Switch off the generator. Always vent oxygen to the outside atmosphere. Avoid closing valves too fast as gas velocities in the oxygen net might become too high, and create a hazardous situation.

Generator fully depressurized and purged with air to remove all oxygen?

Checked for damaged wiring or loose connections, and re-tightened?

Replaced the in- and outlet filter cartridges?

Replaced the activated carbon of the filter?

Replaced the pneumatic valve(s) SV05. Used only oxygen approved grease?

Cleaned the filter of the electrical cabinet?

Replaced the pneumatic valves SV01 up to SV04?

Safety Precautions: Close the generator's outlet valve and the air inlet valve and wait until machine working pressure is 0 bar. Switch off the generator. Always vent oxygen to the outside atmosphere. Avoid closing valves too fast as gas velocities in the oxygen net might become too high, and create a hazardous situation.

Safety Precautions: Close the generator's outlet valve and the air inlet valve and wait until machine working pressure is 0 bar. Switch off the generator. Always vent oxygen to the outside atmosphere. Due to fire hazard, smoking and the use of open flames are prohibited in the vicinity of the oxygen generator. Avoid closing valves too fast as gas velocities in the oxygen net might become too high, and create a hazardous situation.

Generator fully depressurized and purged with air to remove all oxygen before service or inspection?

Check for damaged wiring or loose connections, and re-tighten

Replace the in- and outlet filter cartridges

Replace the activated carbon of the filter

After maintenance activities, the service counter needs to be reset. Contact your supplier.
