New SWG

[Hammond]

Hi. I’m thinking of installing a SWG. It looks like the Circupool 45 RJ+ is popular. I have a 20k gallon pool so I am thinking of getting the RJ45+ (only $10 more than the RJ30).

See attached pics for where I want to install. It’s close to the heater, I’m not sure if that matters. The top long pipe behind the heater is the return to the pool where I would install

Some questions.
1- is this location ok? Is it too close to the heater?
2- I live in DFW area? Should I get the bypass cell? Do people in this area turn the SWG off in the winter? Or just let it go on and off with the water temp?
3-Do I need the cleaning stand?
4- I have a new Pentair VSP that I leave running 24x7. I was going to connect the wiring for the SWG to the same leads as the pump, so if the pump loses power the SWG does too. Is that correct?

Seriously consider installing a heater bypass. This will allow running the pump at a lower rpm when you don't need to use the heater and save money on electricity. The heater restricts water flow.

You may want to keep the SWG cell and wiring away from the heater if the outside heater case gets hot. Looks like there is room to easily moge the plumbing further away from the heater or you can conside a vertical install of the cell. Remember to put the cell in an easily accessible location for maintenance purposes.

Hammond,

Once the water gets below about 52 degrees, the cell will quit making chlorine..

Some take their cells out in the winter, but my guess is that most who live in the DFW are just leave them in..

In the Winter, you will have to use Liquid Chlorine to maintain your FC, but there is not much of an FC demand during the Winter, so it is not much effort.

Where ever you put the cell, keep in mind that at least once or twice a year your will need to remove it, inspect it, and reinstall it.. Not sure how easy that will be behind your heater.

Thanks,

Jim R.

No need for the bypass cell. In the winter when the water is cold, the SWCG will stop producing chlorine. However, the FC demand in the winter is almost nothing. Just dose with LC for those few months. Last winter, I used a grand total of two gallons of LC for the entire season.

Do I need the cleaning stand?

No. If you maintain a slightly negative CSI (zero to -0.3) you should have minimal to no buildup on the cell and will likely go its entire service life without ever having to clean it. Acid cleaning is an absolute last resort.

I was going to connect the wiring for the SWG to the same leads as the pump, so if the pump loses power the SWG does too. Is that correct?

It needs to wired so that the SWCG only receives power when the pump is operating.

Hammond,

If you run the pump 24/7, you can get away with just powering the pump and the SWCG from the same breaker.

Obviously, if you manually shut off the pump, then you need to turn off the breaker so that the SWCG no longer get power.

If you decide to no longer run the pump 24/7, then the SWCG will need to be powered by a timer, or current sensing circuit, that will remove power to the cell when the pump is not running..

Thanks,
