  • Patent number: 5964370
    Abstract: A condensate pan is adapted for use in either a left or right horizontal fan coil installation, and includes left and right mirror image sides interconnected with a central section having on its lower surface a riser near one end, and each of the halves having a drainage opening on the other end, such that when the evaporator coil is placed in the condensate pan, the pan is tipped about the riser to lower one side and raise the other, depending on whether its a left or right horizontal installation, such that drainage occurs from the lower side drainage opening. The drainage opening is so located with respect to the floor of the pan that, when a drain pipe is threadably connected thereto, its lower inner surface is disposed vertically below the pan floor to thereby enhance its drainage characteristics.
