ABSTRACT:
Apparatus for automatically purging the primary reservoir in an evaporative cooler which utilizes a secondary reservoir supplied with a portion of the output flow of the recirculating pump. The primary and secondary reservoirs each contain drain valves actuated when the fluid level therein exceeds a predetermined level. The normal operating fluid level in the primary reservoir is established below the drain level. When the secondary reservoir is filled and drains, its flow is directed into the primary reservoir causing it to exceed its fluid drain level and thus automatically purge the primary reservoir of fluid.
