conditions. This feature is designed to help remove moisture in the air and improve cooling efficiency.  
• You see water dripping from the rear of the unit. Water may be collected in the base pan in highly humid  
conditions or on rainy days. This water overflows and drips from the rear of the unit.  
• You hear the fan running while the compressor is silent. This is a normal operational feature.
