    CircuPool Si-45 Salt System - loud humming noise/vibration coming from control panel

    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!

    Welcome to TFP!

    That is not normal so I suggest contacting your dealer and see what they have to say.

    I just installed the SJ-40. No probs with the control box. Had a leak issue. I was referred to SGS in Arizona by the outfit that I bought the unit from. They are the apparently the manufacturers of the Circupool line. The phone is 480-385-3052....ask for the tech department.

    I had a humming in mine a couple of years ago, right after I installed it. As I recall, I just tightened a couple of screws, and I have not had the humming again.

    Possibly the transformer. Check with the manufacturer as it should be under warranty.

    Thanks everyone for the responses - I appreciate everyone's input. I ultimately sent the unit back to the manufacturer in Texas (free shipping paid for by them) and they will be checking it out. Hoping to get it back from them ASAP as I leave next Monday for a two-week trip. Pool will definitely turn green during that time without a SWG! I'll try to update this post once I receive it back from them and if I get an explanation of what was wrong with the unit. Thanks again.

    Use liquid chlorine in the interim.
