ABSTRACT:
A sediment alert and purging unit for a condensate drain pan and removal return line of a refrigeration system includes an element for monitoring the level of condensate within the condensate drain pan and removal line of a refrigeration system. The unit further includes a switch element in electrical communication with the monitoring element for disabling at least a compressor and air handler of the refrigeration system responsive to an unacceptable level of condensate within the drain pan and removal line. The inventive unit yet further includes an annunciation element in electrical communication with the switch element to alert a user when a disabling of the compressor and air handler has occurred. The unit also includes a purge port within the condensate removal line and a first condensate line closure valve disposed upstream of the purge port. Further provided is a second condensate line closure valve disposed downstream of the purge port. Through the location of closure valves both upstream and downstream of the purge port, a clogged condensate line may be purged, either upstream or downstream of the purge port by effecting the closure of that closure valve located at that side of the purge valve opposite to where the condensate blockage is believed to exist.
