What to do if my NANO NDL-3130 Dehumidifier fails to cycle?
- J
  John HahnAug 9, 2025
  If your NANO Dehumidifier fails to cycle, there are several potential causes. First, ensure the controller is powered and check the on-screen column status to confirm it's powering the solenoid valves during normal operation. Also, verify the power to the unit and the fuse (T2A 250V). Insufficient inlet pressure (less than 4 barg) can also cause this issue, so adjust the inlet pressure settings if needed. If the unit fails to de-pressurize, the solenoid valve may not be functioning correctly; if there is power to the coil, replace the valve. Finally, check the inlet air supply if the outlet flow stops.

Why is my NANO Dehumidifier showing poor dew point performance?
- H
  Heidi MendozaAug 17, 2025
  Poor dew point performance in your NANO Dehumidifier can stem from several factors. Ensure the inlet pressure is at least 4 barg, adjusting the inlet pressure settings if necessary. An electrical fault could also be the cause, so ensure the power is on, the dryer front panel is illuminated, and the dryer is cycling correctly. Check for moist or contaminated desiccant; if present, eliminate the source of contamination and replace the cartridges. Also, verify that the dryer's performance matches the required system air consumption and check the inlet air temperature against the technical specifications. Insufficient purge air, which requires adjustment by service personnel, or a blocked exhaust silencer, also requiring service, could be responsible.

What to do if my NANO NDL-3130 has constant depressurisation?
- L
  Linda DavisAug 25, 2025
  If your NANO Dehumidifier is constantly depressurizing, try switching it off and restarting it. Ensure the dryer is pressurized before powering it on to allow it to initialize before commencing operation. Erratic airflow from the exhaust may also indicate a faulty or damaged valve, requiring service.

  Cody TurnerSep 1, 2025
  Constant depressurization in your NANO Dehumidifier can occur if the dryer fails to initialize. Try switching the dryer off and then restarting it. Ensure the dryer is pressurized before powering it on to allow proper initialization before operation. Erratic airflow from the exhaust may also indicate a faulty or damaged valve, requiring service.
