Grow Room Dehumidifier Maintenance Tip
A customer with five 705 Subcooled Air grow room dehumidifiers was having drainage issues with one unit. Units were located in mechanical area above the cannabis grow rooms. Metal ductwork installed in and out of dehumidifier. Filter racks installed in ceiling return ducts. It turned out that the factory air filter had not been removed or changed since installation a year ago.
The filter had plugged air flow, causing freeze problems and allowing water to pour out of front of dehumidifier. Filter removed, no more problem.
