Atlas Copco Oxygen Generator OGP 160

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?

Close the generator's outlet valve and the air inlet valve and wait until machine working pressure is 0 bar.

The release of nitrogen molecules from the MS is a very slow process. This might cause a pressure build-up in the generator tanks, even after they were depressurized.

Before maintenance, make sure the generator is fully depressurized and purge thoroughly with air to remove all oxygen before service or inspection.

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.

Check the controller for information on the purity, alarms and service messages
