1. An evaporative cooling system comprising:
an enclosure configured to contain cooling media;
a drain valve fluidly coupled to the enclosure and configured to drain fluids from the enclosure; and
an automated flush system comprising:
a control circuit coupled configured to determine whether a day count period associated with an operating frequency has expired;
a photocell configured to detect ambient light indicative of daytime; and
the control circuit coupled to the photocell and the drain valve and further configured to:
compare an output from the photocell to a threshold to determine if a predetermined amount of time has passed after the day count period has expired; and
when the threshold has been passed, open the drain valve.
