Abstract

See full text

A drain pump assembly is provided for use with an evaporative cooler having a water reservoir and a circulating pump. The drain pump assembly includes a drain pump operative to pump accumulated water from the reservoir when the drain pump is turned on and a controller. The controller is operative to turn on the drain pump automatically after the circulating pump has operated for a predetermined circulate time period and also is operative to turn on the drain pump in response to actuation of a manual drain actuator. The controller turns on the drain pump for a drain time that is equal to or greater than a predetermined drain period. The controller can terminate operation of the drain pump and reset the drain time is power to the circulating pump is interrupted during operation of the circulating pump. The controller includes a processor and a data storage device operative to store data representing the accumulated circulate time when power to the circulating pump is interrupted. The processor is programmed to calculate an accumulated circulate time during which power is applied to the circulate pump; control the switch to operate the drain pump for a predefined drain period when the accumulated circulate time is equal to or greater than the predefined circulate period; monitor the actuation of the manual drain actuator; control the switch to operate the drain pump for the drain period in response to actuation of the manual drain actuator; and reset the drain time if power is removed from the drain pump during the drain pump operation.
