    installing Hayward Max Flo 1HP, simple wiring question

    Just got my new Max Flo 1HP single speed pump today and getting it connected. Have the 12/2 wire for the 110V set up. Got my black, white and ground. Simple question, but need some confirmation since the manual has little info. The connections are labeled L1 and L2. Which one is the hot (black)???

    Much appreciated!

    It doesn't matter.

    From the manual, page 9 To Wire a Single Speed, Single Voltage Motor There are two terminals labeled L1 and L2. Attach the power leads to these terminals. Either wire may attach to
    either terminal.

    Pump wouldn't start. Checked connections - thought there was maybe one loose one, corrected it...still nada.

    Check and make sure the jumper for the 240/120 is in the correct position. Sounds like it may be set for 240.

    Checked that. Maybe I made an assumption on 110? The motor runs through a timer box that's 110, so it would have to be all 110 correct? One breaker...wire gauge already in there is 14....which according to the manual is recommended for 230....confused.

    Re: installing Hayward Max Flo 1HP, simple wiring question

    On the electrical tag on the motor it will have a box with the voltage and one with the amps numbers. Can you post what those are? Most times, motors, if they are a dual voltage, are set for 240. There is usually a jumper or a wire that has to be moved to set it for 120. This is if the motor is set up for dual voltage. What is the model number of the pump?
    Don't know what to tell you about the timer box unless you can show us a picture of the inside of it. We may be able to tell if it set for 240 or 120.

    Got it going. Thanks for your responses. Contacted the previous owner and confirmed it was 230v. Made the switch on the pump back to the factory 230 and re-installed 14/2 wire and boom. Runs like a dream. Thanks again.
