The moisture that the enclosure air can contain is limited. If moisture flows from the drain tube continuously, this can only mean that ambient air is entering the enclosure. Remember that frequent opening of the enclosure’s door admits humid air which the air conditioner must then dehumidify. © 2013 Pentair Equipment Protection 89048707 - 6 - RSPSupply - 1-888-532-2706 - www.RSPSupply.com... -
