Just installed a CircuPool Si-45 salt system on my 10K gallon pool in AZ, along with all new equipment (Pentair Intelliflo pump, Pentair Quad DE 60 filter, Pentair commercial grade backwash valve, Jandy 3-way valve, and piping). When I turn the salt cell on at the control panel, it's very quiet for the first 4-5 minutes and the control panel shows everything is working correctly. However, after those 4-5 minutes, there's a fairly loud humming noise/vibration coming from the control panel. Anyone have any idea what the issue is, or is this normal? I have the control panel mounted to the side of my house and I can hear it throughout almost all of my house.
I left it running for a full 8 hours and never experienced any warnings (red lights) on the control panel and it is producing the correct amount of chlorine. However, I'm slightly worried about the risk of fire since the humming noise/vibration does not sound normal to me. This is a brand new unit - should I send it back to CircuPool? Any other suggestions?
I'm new to this site and it has so much great information. I've read many of the threads in this forum and everyone is very helpful here so I appreciate the responses in advance!
