A licensed pool professional just installed a Pentair WhisperFlo VST pump and didn't show us how to use it afterwards. The owner's manual doesn't give any advice regarding programming speeds or schedules. If anyone on here has this pump or has a similar Pentair variable speed pump, I have a few questions that I hope someone on here would answer for me:
If we want to keep the pump off for 10 hours at night to keep the skimmer from filling up with leaves during the night, how many RPMs should we operate the pump during the day?
Should we increase the speed at 7 PM when we normally add liquid chlorine? If so, how many RPMs should we increase the speed to, and how long should the pump operate at that speed before the pump turns off for the evening?
Is it normal for your sand filter to register a higher than normal filter pressure after getting a variable speed pump installed? Clean pressure is at 32 now, which is higher than normal. When we turn the pump off, it only goes down to 22, instead of 0. Is this a sign that the gauge is broken or is this normal? If this is a sign of a broken gauge, do I need to replace it before starting a SLAM tomorrow or can I just backwash when it goes up by 20%?
How many RPMs should I set the pump to during a SLAM? Should I increase the speed for an hour or two after adding chlorine each time or can it run at the same speed for 24 hours a day until it clears up?
When vacuumming the pool with a manual vacuum during the SLAM or afterwards, do we need to increase the RPMs? There is a Quick Clean button that you can press when you want to temporarily increase or decrease the speeds during cleaning.
