I discovered today that not only does my IC40 claim to be generating at 600rpm but the flow light stays on even when the pump is off altogether! I assume that is a fault with the unit which had not been used for 5 years or more before I resurrected it this last week. Do you think its safe to have it running with the pump at 600rpm or should I use the old intermatic timer that it is connected to and have it only running when the pump is on its higher (2500rpm) part of its cycle ?Thanks. Good point, I will dial-it down to 60% initially. I have a basic question on how the IC40 works: Is it a binary either its generating chlorine or its not or does it generate more chlorine the higher the pump speed?
The people who intstalled the IC40 wired it up to an old intermaitc timer that was used on my old pump so in theory I could use that as a control as well.
