Aquarite flow switch

[cmack]

I'm plumbing in a new Aquarite cell. But there is no room on the output side of filter. Unless I do a total replumb.
Question: Can I install the flow switch 12" upstream on the in side of my cartridge filter? I called customer service and they told me where it was supposed to be located. Which I already knew. and basically told me that I could try installing to the in line and see how it goes.
Any input would be great. I really don't want to replumb my whole system.
Thanks guys

The flow switch must be in the same line as the cell, with no valves, fittings, diverters or anything that may divert flow away from the cell. Once the flow switch detects flow, that same water flow must go through the cell also. This way there are no possible ways for the cell to be energized without proper water flow to evacuate the chlorine and hydrogen gas generated by the cell.
(Hydrogen gas buildup can potentially result in an explosion)

Thanks Sean,
Well that's not the answer I was looking for. I do understand the danger of Hydrogen gas buildup. But when there is water flowing through the in line then its also going through the cell unless I shut down a valve in which case the switch would de activate the cell right!!
I dont' want to have troubles down the road. How about plumbing the switch right at the base of the return line? Its below a valve though. Thats how the aquarite book shows it figure #2 page 10 below a valve.
Thanks again for the input.

I have a different flow switch problem. My switch is installed but prior to plugging it into the panel, the *&(%+$ Dog gnawed the wire and bit off the telephone style plug. I called Goldline and they wouldn't tell me which of the pins are used. All I have to do is splice a new cord to the remainder of old one. The lady at Goldline said "oh, you can't do that and the only solution is to replace the whole thing. $150.00 plus $10.00 shipping". Wow... Anyone know which of the four pins are connected to the two wires.
Thanks

Just give me $10 and I can help you figure it out. ; )

The flow switch should be a micro switch with either an open circuit or closed circuit. A replacement phone style jack should be available from Home Depot, Radio Shack, Lowes... and yes, you will need to figure out which wires are used.

If you take the wires from the power supply, take one set of wires and short them together until you see the flow indicator status show that the flow is good. Those are the two wires used to determine flow. You should be able to use a multimeter (on continuity or ohm) to determine the open and closed circuit on the flow switch (and should be done with the power off and the flow switch removed - move the flow switch paddle by hand).

Hope this helps,

If you end up needing a replacement switch they have it here a bit cheaper: http://www.h2opoolproducts.com/produ...roducts_id=542 - still $75 and overpriced but that is half what they wanted!

Another option if your unit is under warranty would be to call and say your unit flashes no flow and you can't figure out why. The switch is probably considered a throw away part so either they wouldn't want the old one back or would chuck it in the trash without paying much attention when they got it back. Not saying you should do that, use your own moral judgement, just putting it out there.

The middle 2 pins are the ones that need connected to the switch.
When they are bridged, the unit registers the flow. So those are the ones you need to attach to.

Hey guys, thanks for the help. It's now up and running and doing great.
Thanks again
