Atlas Copco Nitrogen Generator NGP 12+

Warning: Before carrying out any maintenance or corrective activity read the following recommendations and safety precautions and act accordingly:

Close the nitrogen outlet valve and air inlet valve and wait until the entire installation is depressurized.

If required remove canopy panels and wait at least 5 minutes before starting any maintenance work.

Danger! The release of nitrogen molecules from the CMS is a very slow process. This might cause a pressure buildup in the adsorber vessels, even after they were depressurized.

Before maintenance, make sure the unit is fully depressurized 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 unit.

Always wear personal protective equipment, such as eye- and ear protection. Furthermore, it is strongly recommended to wear a device, which will give an alarm, if the oxygen level is below 19% (risk of asphyxiation) or above 23% (fire hazard), in the area you are located in.

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