My old single speed pump developed a serious leek and needed to be replaced. We decided to go with the Pentair superflo VST. We also have a Hayward Hayward aqua rite 900 saltwater system. My question involves the electrical hook up. The installer simply hooked the pump up using the existing wiring that was coming out of an existing timer that is also turning the salt system on and off. He told me that pump had to have constant power and to just leave the timer in the on position all the time. This means that the flow switch for the salt system now turns on and off the salt system..... which I know is bad if that flow switch shots. So that explanation leads me to my electrical question. Obviously I want to have constant power going to the pump, but would like to have the timer still control the salt system. My plan is to simply tie in the pump to the line in side on the timer. I just want confirmation that the terminals line side on these timers are always 1 and 3 and the load side is always 2 and 4. Also other then making sure I have the ground wired right, it shouldn’t matter which color wire I hook up to the load in terminals does it? I have a timer that I’m pretty sure is just like this one.
