Thermal Edge air conditioners operate as a “closed loop” system with no exposure or introduction of outside air. This ensures that the enclosure is separated from and is not contaminated with ambient air, dirt, chemicals, dust, moisture or foreign matter so that sensitive enclosure components are protected and are kept at your required operational temperature. - Page 6 In the event of excess water vapor where the enclosure door has been left open there is an overflow hole on the bottom of every unit. Please contact Thermal Edge Inc. if you encounter excess water coming from your air conditioner.
