Only start up the dryer once you have thoroughly tested all the compressed air, refrigeration and
electrical connections.
1. Close the isolating valves on the dryer and open the by-pass valve.
2. Check on the controller that the dryer is OFF.
3. Start the air compressor.
4. Start the dryer. (press on the arrow up button, the controller will display ON)
5. The refrigerating compressor and condenser fan will start after a 2-minute safety time-out interval.
6. Always turn your dryer ON 10 to 15 minutes before the air compressor.
7. Pressurize the dryer by slowly opening the inlet valve.
8. Slowly open the dryer outlet valve and then close the by-pass.
9. Check that the condensate drain opens when you push the arrow's down button.
10. Check that the condensate drain valve opens automatically every 5 minutes.
The dryer is now ready to run normally.
The following key points will optimize daily use:
• Always turn your dryer ON 10 to 15 minutes before the air compressor. This will ensure that the heat
exchanger has been cooled to a proper level to handle the initial thermal load of the compressed air.
• The NXC cycling refrigerated air dryer has been designed as an energy efficient air dryer and can remain
on even when compressed air production has stopped. The electronic regulation will automatically start
and stop the refrigeration compressor based on the demand on the system. You only need to turn off
your air dryer at night, on the weekend or during system shut down.
• The standard dryer parameters programmed in our factory meet the needs of most applications. If
the conditions in your plant are typical (i.e. not a very hot environment, no partial drying upstream, no
voluntary increase in the dew point...), do not spend time on modifying these parameters.
