Caution: Each time that a regeneration tower depressurises, a loud noise is produced. This occurs every 2 minutes.
In dryer models with pre-filters and electronic auto-drains, every 4 minutes, the valve at the bottom of the pre-filter opens
automatically and discharges condensate for 4 seconds.
The cycle times are fixed and cannot be adjusted by the user.
