I would suspect from a fail safe aspect, you would want the flow up through the flow switch and cell. That way, if the flow switch flapper malfunctioned it would fail open, or no flow, versus if the system installed the other way, it would fail closed, or on. Might be overthinking this as we all do sometimes!!
Yes, that was the jist of the other's idea, to go up through the SWG, not down through it. And yes, probably overthinking. Didn't mean to pile on the OP, but if it were me I'd want to know all the considerations and then decide on best practice, so I only had to cut and glue once...
This from another forum, that I think is saying exactly what Marty just did:
The display panel of the IntelliChlor cannot be repositioned. When installing the unit vertically, be sure to install it in such a way that the water flow is traveling upwards through the system. This adds another safety to ensure that the weight of the water does not depress the flow switch when there is no water movement.
And this from JoyfulNoise here on TFP, though he may be indicating the opposite direction? A bit beyond me, I think I'll leave mine horizontal...
I think the only requirement I know of is 12-18" of straight PVC before the input side of the IC60 to ensure that turbulent flow does not mess up the flow sensor. The flow sensor looks like a plastic tab with a magnet on the end that dangles in the water stream. If the flow is too low, then the magnet does not get pushed close enough to the internal reed switch to make closure. I think the input side is up so that the magnet isn't impeded from making proper closure. If it's oriented the wrong way vertically, then I think it takes greater flow rates to move the magnet and the flow sensor may not make closure at all.
Give Pentair technical support a call, they are helpful.
