Actually, it does have ventilation with sun shelter with the tarp I have over it. The tarp is over the filter so several feet above the pump. I can't really relocate it. So, if your has been hot and running fine for years, maybe I don't need to be concerned. I just don't want it to die on me and then I have to pay full-retail price because I'm in a pinch when I might be able to get one online for a better price if not in an emergency.
