Hi,

CSA requires any submersed device to have certain requirements (like a 3 pong plug and grounding and such). So, in order for Hagen to sell this device in Canada without massive modifications, it must put this label on there to be CSA compliant. It is probably designed to be submersed, but it does not met the strict rules that CSA has.

I was never any good with my electricals. So what does it mean if an electrical device doesn't have 3 prongs? I know the 3rd prong is for grounding but what does that mean in terms of me sticking my hand in the salt water if the device starts leaking electricity? On all of my pumps, they have 2 prongs and both prongs are the same size.
