    Why is there water downstream of my HANKISON Dehumidifier?

      Ashley ThomasAug 3, 2025
      If you find water downstream of your HANKISON Dehumidifier, it could be due to several reasons. Residual free moisture might be present in the downstream pipelines, in which case you should blow out the system with dry air. Also, check the valve positions to ensure the air bypass system isn't open. Verify that the inlet and outlet connections are correctly connected. If air lines downstream are exposed to temperatures below the dew point, insulate or heat trace them, or use dry air to lower the dew point. If there's excessive free moisture at the dryer inlet, install a separator ahead of the dryer. If the condensate is not being drained, or the dryer is overloaded, or the refrigeration system isn't functioning, see section C for more details.

Look at the display for any fault indications related to high or low pressure cutouts. If the service interval has elapsed, perform the scheduled service. For hot gas bypass valve adjustments, contact a qualified technician or the manufacturer’s service department. Ensure adequate condenser cooling by checking the air temperature in front of the condenser, cleaning the condenser, and verifying free airflow, as well as checking the fan and switch operation. Also, check the temperature and flow of the cooling ...
