To Next PageTo Next PageWhat to do if my SPX Hankison HPRP Dehumidifier refrigeration system is not functioning properly?
If the power light is off, ensure the unit is receiving power. Also, close the disconnect switch and check for continuity. An electrician should inspect the electrical connections. Verify the unit operates within the minimum and maximum temperature ranges. Clean the condenser and ensure there's adequate airflow.
Why is there high pressure drop across my SPX Dehumidifier?
A high-pressure drop could be due to the flow rate. Check the flow rate and replace the filter element.
What to do if there is water downstream of my SPX Hankison HPRP?
To address water downstream, blow out the system with dry air. Also, check the valve positions and ensure correct connections. Insulate or heat trace air lines exposed to low ambients, or use dry air to lower the dew point. Consider installing a separator ahead of the dryer.
