New Pentair Superflo VST - have questions

[AngelaKelly]

Our pump officially died last Sunday, our new Pentair Superflo was installed today. Our pool guy installed and left and I have questions -

1) Our pump is on a timer, 12 hours. Our pool guy set this to 3000rpm. Do I need to adjust?

2) Our filter psi, with our old pump, was around 10-11, with the installation of our new pump, it dropped to around 5. Is that ok?

3) Any guidance/direction on using the new pump correctly?

Thanks!

Why is the pump on a timer? Is the SWCG on the timer also? Post a picture of the entire pad.

If there is no reason for the timer (SWCG), then I'd leave the timer on 24x7.

The pump has 3 scheduled times available.

Backwash the filter. If you signature is correct and complete, lower the pump speed in 100 increments until the SWCG turns off due to low flow. Then increase 200 rpm and run at that speed, 24x7. Adjust your SWCG output for the 24 hour runtime.

See page 8 here for programming.

When I went out to take pics I noticed that our pool guy did not turn back on the skimmers so I turned them on and the PSI went up to 10!

Here are pics of the complete pad and pump readings. It appears the pump is set to run for 24 hours but also plugged into the timer for the old pump/salt cell. I believe I can have that timer completely removed at this point.

I will read on up on the programming piece to make sure we program it correctly.

Without automation you need the timer for the SWCG. It must have its power completely removed when the pump is off.

The pump should be wired to the LINE side of the timer, or directly from a circuit breaker.

You can adjust the rpm of the pump down to what the SWCG needs to satisfy the flow switch. Then see if that sufficiently provides skimming needs.

Ok! To clarify, does it appear that the pump is not wired to the line side?

The flow light on the SWG comes on when I adjust the percentage so should I assume it is working correctly?

I have no idea on the pump wiring. Does the pump lose power at any time?
Changing the generation % on the SWCG does not effect its flow.

No, the pump is new. I will confirm the wiring with our pool guy. Thank you.

Turn off power to the timer while the pump is on. If the pump then turns off it is wired to the output of the timer which is incorrect. The pump should be wired to the line or hot side of the timer so that it's not controlled by the timer but rather by it's internal programming. Then only the salt cell should be on the load or output side of the timer by itself, set to turn on after the pump comes on, and to turn off before the pump turns off.

It appears to be wired to the wrong side. Super.

They probably just left it the way it was with your old single speed motor and simply hooked it back up to the new motor.

It appears that way. My next question - is this a major issue? Will a standard electrician know how to fix? Thanks for your help!

Yes, it's an easy fix. It might take 15 minutes tops.
