Thought I'd post this info. Might be useful to someone
While an ic15 can be positioned horizontally or vertically, if installed vertically the unit most point up allowing the water to move upwards. This is to, according to Pentair:
"This adds another safety to ensure that the weight of the water does not depress the flow switch when there is no water movement."
My initial question was to find out if the control panel of the unit can be repositioned to be right side up. Since this would imply the water to flow downwards, the fact the control panel cannot be repositioned became irrelevant.
