Well after the first week of running the Pentair Intelliflo 24/7 on High speed, I have got the Intellitouch programmed with the following speed assignements -
Pool runs from 8am - 8pm
Polaris Legend cleaner runs from 8am-11am
Pool pump speed - 2100 RPM
Pump speed when cleaner is on -2300 RPM
Pump speed when spa turns on - 3150 RPM
So every morning when the pool and cleaner start, 1 of the return lines blows air bubbles out. It's the one closest to the cleaner hose.
This did not do this when the pump was running 24/7 nor did it do it when I shut the pump off and turned it back on. COuld this have something to do with the Polaris or maybe the reduced pump speed? Somehow air is getting into that one return line between 8pm and 8am.
