Getting sick of putting chlorine in

[mguzzy]

Wouldn’t that entail making the cell upstream of the flow switch? The instructions say the flow switch has to be upstream of the cell...another manufacturer error?

Well you made me look up the install manual.. and you are right, it explicitly states that the flow switch for the Edge should be upstream of the cell. I wonder what is different about this cell config that they make that requirement. If you look at the RJ series install guidelines it says the flow switch can be put downstream of the cell and the cell can be counted in the straight run. hmmm.. Does anyone else have some insight into that?

 

[mguzzy]

Well, on the Hayward Cells, we are allowed to install the flow switch downstream of the salt cell. And the salt cell really helps straighten the flow. But it uses a flapper type switch. If the switch is a pressure switch (like my heater) you definitely would want it upstream of the SWG.

That makes sense.. and to add to the confusion, the manual has a picture of the flow switch that looks like a pressure switch, but in schematic drawing its a flapper... so @Rodex what actual kind of flow switch gizmo do you have? maybe post a pic of what the switch mechanism looks like.

Flapper

That will be BEST downstream of the salt cell. The salt cell straightens the flow quite well and gives you a decent laminar flow. Flaps don't like turbulent flow. Make SURE SURE SURE to install the flap in the correct direction!

Both the cell and flow switch directions are clearly marked and I’m assuming flow direction is exiting the filter and then going underground. If you’re positive this flow switch is best downstream then that means in the dry fit picture attached, I’ll move the cell toward the filter and put the flow switch where the cell is.

I am 100% sure. That is how mine is hooked up.

Where is the flow switch in your dry fit? From your pic it looks like you have more than enough space to install it either way"
Filter->6"->flow Switch->Cell->elbow
or
Filter->6"->Cell->flow Switch->elbow

I would be tempted to just follow their guidelines in that case. ( I love seeing the weapons of destruction on the ground, ready for the next cut!)

I hadn’t made the cut yet.

With this dry fit (reversed obviously), there is just barely 6” of straight pipe from the back flow valve.

 

[Rodex]

Manufacturers suggestion. There’s maybe 7-8” from the valve itself to the actual flow switch. I’m also tempted to go this route in case the manufacturer plus shenanigans with the warranty....

Yeah.. the manufacturers warranty shenanigans usually trumps other options.. Its better safe than "Sorry you have violated the terms of your warranty"

 

[Rodex]

Ok, pieces glued in. Followed the manufacturers suggestion to leave the cell out until the glue dries but I did put it beside the pieces and looks like it’ll be a good tight fit. T - 1.75 hours!

If I recall you added your salt at page 2! Is the salinity already where you want it!

I did not.....I have all the salt but I was maybe prescribed to the order of operations a bit too rigidly... I was planning on adding it tonight.

Oh.. ok.. Then make sure you do not turn on the SWG until the salt is dissolved and mixed. you don't want the cell to get a blast of high salinity water. And I like to dump it in the shallow end and by the time I sweep it to the deep end, its dissolved.. and add it in stages and test between additions so you creep up on the target salinity.. The only recourse to adding too much salt is to drain and refill. I learned that one the hard way almost when I over estimated my pool volume. Actually I was following my pool stores advice at the time, and going by what THEY thought my volume was. I don't listen to them much anymore.

Yeah I was just going to leave it unplugged until salinity target is reached. Once that happens - just keep adjusting the controller and testing FC? I started high at 8.5 last night because I was doing OCLT, target was 7 but overshot a little.

My CYA needs to come up a bit (currently at 50) and TA is high at 100. CH is 225 so also needs to come up.

 

[mguzzy]

Perfect.. go ahead and start bringing your CYA up to target for a SWG.. you are in Texas anyway so no worry there (more sun more CYA). And adjust your CH accordingly. I wouldn't worry about your TA right now.. you are close enough and the other additions may drop it a bit. Then once you get everything going, you can do the aeration dance to drop your TA.

 

[red-beard]

The CYA right now and CH will not hurt things. Keep your CH on the low side of the range to prevent buildup on the plates. There is an article on SWG that running as close to -0.3 helps prevent plate deposits. I am presently running -0.56 because I just added 4 lbs of CYA (50 to 70 for 25K gallons) and it is quite acidic. The "A" stands for Acid!

I dump my salt in the shallow end of the pool and sweep it from side to side in the shallow end with my brush until dissolved. Shoot for the middle of the range with the salt addition. It takes a while to mix. You might consider "brushing your pool" to help it mix. Also, running the pool cleaner helps it mix.

@red-beard's post made me want to remind you.. you are transitioning to a SWG pool.. so you will be using slightly different targets now...
