  Debra HodgesAug 25, 2025
  A high pressure drop across your HANKISON Dehumidifier can stem from a few potential issues. Excessive airflow could be the cause, so check the flow rate. Another possibility is the freezing of moisture in the evaporator due to a refrigeration system fault; in this case, consult section D. Lastly, a clogged separator filter element can lead to a pressure drop, so replace the filter element.

  If the dew point indicator on your HANKISON Dehumidifier is in the red area, this suggests that the dryer is overloaded, leading to a high air outlet temperature. Refer to section A 7. Alternatively, the refrigeration system might not be functioning properly, also resulting in a high air outlet temperature; in this case, consult section D.

  If you notice water downstream of your HANKISON Dehumidifier, several factors could be responsible. It might be due to residual free moisture in the pipelines; in this case, blow out the system with dry air. Check the valve positions because the air bypass system might be open. Ensure 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. Excessive free moisture at the dryer inlet might be the cause, so install a separator ahead of the dryer. Condensate drainage issues can also lead to this problem; ensure the drain mechanism isn't clogged or inoperative, the drain line isn't restricted or frozen, and, for electric drains, the timer is set for...

  Several issues can cause the refrigeration system of your HANKISON Dehumidifier to malfunction. First, check if the power is on. If the power light is off, ensure the unit is receiving power. Verify that the line disconnect switch is closed and inspect for blown fuses or open breakers, checking for continuity. Faulty wiring or loose terminals can also be culprits, so have an electrician inspect the electrical connections. High or low ambient conditions might affect the system; check the minimum and maximum temperature ranges. If your system is air-cooled, inspect for dirty or clogged condenser fins and ensure there's no obstruction to airflow across the condenser. Also, check the fan motor or fan control switch. If the issue persists after cleaning the condenser and ensuring free airflow, ...
