Minimum rpm for Jandy PLC1400 swg?

[NaCLTPool]

What’s the minimum rpm needed for the swg to run? I’ve seen mixed answers unless that’s dependent on the set up.

 

[mknauss]

Depends on your equipment, layout, flow switch, etc.

With a heater, start at 1500 rpm. See if that meets the needs of the flow switch. Go up or down to find the rpm that satisfies the flow switch. Then add 200 rpm.

Thanks. Is this only when the heater is running or because water is passing through the heater at all times even though it is off? Trying to find my lowest possible rpm while the swg still runs, although this may take be may take me messing around with it.

Just to add, the pool orientation company said we shouldn’t run it below 2300rpm and that running it 18 hours per day would be good. Not sure what their logic is behind that.

Correct. Some install bypass systems to be able to run at lower rpm. You likely will have to run at a higher rpm when you wish to run the heater. It has a pressure switch in it to be sure you are running enough water through it when fired.

That is the no call back method. Higher rpm and longer run time than needed. They don’t pay your electricity bill.

Na,

As Marty points out... every pool set up is different and you will just have to experiment to find what works best for you..

I find running 24/7, at a low RPM works best for me.. I like making a little chlorine all the time, and and skimming all the time. I also like the look of my pool when there is a little motion to the water.

Without any proof at all, I personally believe that running 24/7 is better on the pump, then turning it on and off each day. I have been doing this for well over 10 years and my pumps run today, just like they did when new..

My cost to run 24/7 is less than $20 bucks a month.. That said, I do not have a heater and can run slower..

Thanks,

Jim R.

I need to take a picture of my equipment but it looks like there is some type of valve that would shut off the water going to the heater and bypass it. Is there any downside to closing this to run at a lower rpm?

Obviously in the fall I would open it back up since that is when I’ll likely first be using the heater

Bypass the heater. Turn the pump down until the aquapure flow switch stops cell production. Add 200 rpm to allow for filter getting dirty, and run at that speed.

Is there a way to calculate my electric bill based on $/kwh and RPM and run time? Right now they have it set up at 2500 RPM for 24/7 and I can tell my first bill is significantly hire than the month before and last year at the same time.

Thanks. If the skimming action isn’t great at the lowest RPM, would it make sense to have a few hours at a higher ( example: 2 in the and 2 in the pm) for the skimmer?

 

[PoolStored]

This will be pretty close, would have to use your own utility rates, and watt/rpms for your pump. The relative would be the same magnatude:

Yep.

 

[mknauss]

Be sure you have a weir door in your skimmer.

 

[NaCLTPool]

Be sure you have a weir door in your skimmer.

Is this the thing inside the skimmer box that moves up and down with the water movement? (best way I can describe it)

 

[mknauss]

Yes

 

[NaCLTPool]

Yes

got it. thanks. going to experiment with running 24/7 at the lowest rpm that the salt cell allow besides 3 or 4 hours at higher RPM for the skimmer

 

[NaCLTPool]

I was messing around with my salt cell to find the minimum RPM needed for flow. I went down to the minimum of 600 RPM and it looked like the cell was still on. Is this accurate? My goal is to set it low for 20 hours then have 2 hours in the morning and 2 hours in the evening at increased RPM for skimming.

Yes, it says FLOW and the cell is generating.

 

[NaCLTPool]

Yes, it says FLOW and the cell is generating.

with that being the case, is the recommendation to set it 200 RPM above that? Or even though it is generating chlorine, I won’t have much water movement set that low?

If you have flow at 600 and not at 500 then you should add 200 to the 600 and use 800 as your minimum flow.

Or even though it is generating chlorine, I won’t have much water movement set that low?

That is correct. Depends what you want to achieve.

I think you are making your speeds and schedule more complicated then it needs to be.
