2 sp to VS assistance

Hi, My Hayward 2 speed crapped out and I ordered a replacement VS pump, Hayward SP3202VSP. I have Goldline PS-8, revision 4.30 which apparently will work the VS according to a Hayward rep, Goldline SWG, Hayward 400 btu,nat gas heater, polaris 380 with booster, and 3 water jets that shoot from pool deck into pool. Pool is 29.5k gallons with attached spa, 2"plumbing, quartz finish.

My question is figuring out various speeds to do what I have been doing. I have used high speed to operate the Polaris for two hours and then ran low speed for another 18 hours per day. With the 2sp, I would kick it to high for operating the jets, Polaris or heater. My pool company seems knowledgeable but people on here seem very experienced and provide great incite. I have used this board for info regularly the past 7 plus years.

My question involves suggestions as far as scheduling the pump speeds, and or any other advise as I have no experience with a VS pump but I got it for a great price so I made the move.

Thanks for any input.
 
For skimming, slower speeds are better and an SWG produces the same amount of chlorine as long as the speed is adequate enough to activate the flow switch. So, when you get the pump installed, you'll need to do a little bit of testing. Run the VSP and lower the speed until you can cause the SWG to throw a flow error. Then add back an additional 100RPM or so and keep it round numbers for simplicity. So if your SWG trips at 1230RPM, I would bump that speed up to 1350RPM. That will be the speed for your standard POOL mode - whenever the pool is running and you need to generate chlorine.

As for skimming, some people run their VSP's 24/7 at a really low speed - a speed just high enough to get some detectable and steady flow out of the returns that keeps the skimmer pulling debris in. That will probably be lower than the flow limit of the SWG (or close to it) and you can, if you wish, let the pump run at that speed 24/7.

For the Polaris, I am assuming it doesn't have a booster pump(??). If that's the case, then you'll just need to dial up a high speed that can satisfy the needs of the polaris for whenever you schedule it to run. VSPs usually have pretty high horsepower so I sincerely doubt you will ever run it as high as the maximum pump speed (3450RPM). Honestly speaking, I ditched my suction side cleaner this year in favor of a robot so that I could decouple the cleaning of my pool from having to use the pool pump. I couldn't be happier with that decision.

Thank you, I do have a booster pump for the Polaris but in the past I always had the 2 sp pump on high during the robot cycle.

Ok. Perhaps some other folks that use pressure cleaners with VSPs can comment on what speeds they use. I sincerely doubt one needs to use the full speed of a VSP when a booster pump is present but it would be better to get a first-hand opinion on that.
 
I think you could use a very low speed on a vs pump. The water just needs to be moving a little bit for the booster I think. Basically the booster pump doesn't it have the ability to pull the water from the pool so you just need your main pump to be doing that.
 
My suggestion would be to start the VSP at half its normal speed then turn on the Polaris and see if it runs as expected. If the Polaris seems to run fine, then start lowering the VSP speed until the Polaris starts acting weird. I bet you'll probably be able to run the pump at quite a slow speed and the Polaris will still work.
