Hi. My spa light niche (for Pentair light 7810600) is installed sideways, to where the mounting screw is at 3 o'clock. I have contacted Pentair, and they state that this is not a problem. However, I see all over the place, including the Pentair installation manuals, that the niche screw MUST be mounted at 12 o'clock for grounding safety. Can anyone confirm if this is, or is not, an issue? I hate to think of what it would cost to repair it.
