Cell mounting

[polyvue]

I am is the process of installing an Hayward Aquarite system. Due to how my filter / pump are plumbed, I cannot install the T-15 cell upright. I was wondering if I can mount the cell "upside down."

As PoolSean advised, the axis of the cell is inconsequential. My Goldline manual states that "the water may move in either direction through the cell", so that pretty well encompasses every which way you could install it. The flow switch can be plumbed before or after the cell but in the same section of pipe. There should be at least a 12" straight run of pipe before the flow switch.
