Working on  the "Venturi" principle, the Mermaid Condensator is installed in-line with the marine air conditioners water discharge line. 

As  the marine air conditioner and sea water pump are running, the device  creates a vacuum effect and literally pulls the condensation water out  of the drain pan, merges it with the discharge water, and your  condensation is now overboard!

The principle here is to leave your boat a "dry boat" by removing all condensation from the marine air conditioners drain pan. 

The Mermaid Condensator is 6 inches long including the inlet/outlet water hose  barbs. As long as you keep this marine Mermaid condensator clean, it will work  hard for you. For your convenience, we ship all units with everything  you need for installation.
