Drain line access device with interior overflow safety switch

摘要

An access device for installation to a condensation drainage system, such as a drain line of an HVAC unit, includes a main body with at least one connecting port for sealed, fluid receiving connection to the drainage system and an open top communicating with an interior cavity. A top cover releasably secures to the main body to completely cover the open top. An overflow safety switch is removably held in operable position within the interior cavity and below the top cover. The switch senses the level of condensate liquid accumulating with the interior cavity and sends an electronic signal to disable the condensation producing equipment if the liquid reaches a predetermined level.

主权项

1. An access device for inline installation to a drain line of a condensation producing source, said device comprising:
a main body having an open top communicating with an interior cavity, and said main body including at least one connecting port sized and configured for sealed connection with the drain line; a top cover releasably securable to said main body to completely cover the open top of the main body, and the top cover being releasable from the open top for accessing the interior cavity of said main body; an overflow safety switch structured to be removably held in operable position within the interior cavity of said main body and below the top cover, and said overflow safety switch being structured and disposed for detecting the level of condensate liquid accumulating within the interior cavity of said main body and being further structured and disposed for sending a shut-off signal to the condensation producing source upon detecting the condensate liquid reaching a predetermined level within the interior cavity; and a bracket removably mounted to said main body entirely within the interior cavity and concealed below the top cover, and said bracket including an open clip member structured for removable and snap-fit attachment to adjustable positioning grooves of the overflow safety switch for holding the overflow safety switch in the operable position within the interior cavity with the overflow safety switch entirely concealed below the top cover, and the open clip member on said bracket being structured and disposed to allow removal and replacement of the overflow safety switch in attachment to said bracket without removing said bracket from mounted position to said main body within the interior cavity.
