Note: these are 230V only motors. Timer installation pretty much REQUIRES an electrician. You will DEFINITELY need to purchase the appropriate "Go-Kit" when you get the motor. There are electronic switches available, but one of the benefits of a 2 speed pump over a variable speed pump is greater reliability and MUCH less susceptibility to nearby lightning. Going with an electronic timer somewhat undoes this. If you get the connection 'whip', your electrician will need to add 1 additional wire.
