• Ensure that the towers are not under pressure and disconnect the dryer from the system.
• Unscrew the bleed plug.
• Fully remove the adsorbent from the towers.
• Screw on the bleed plug.
• Unscrew the filling plug.

Deterioration of adsorbent can lead to reduced performance of
the air dryer. If you are unable to monitor the quality of dried air,
then you should change the adsorbent every 3 years.
