Question about Hayward 2HP Pool Pump Motor A O Smith Electric Pool Motor for 56J Frame

1 Answer

Replaced Single Speed Pool Pump Motor with 2-Speed Motor

I have just swapped out a single speed A.O.Smith 2HP Pool Motor for a 2 Speed Energy -Efficient A.O.Smith Pool Motor (Same HP).
The old motor had 3 terminals in back - L1 (Common) L2 and a Ground Wire.
The new 2 Speed has 4 terminals - L1 (Common) L2 (Hi Speed) "A" (Low Speed) and Ground Wire.

I suspect that I need to run an additional wire from the control panel to the "A" (Low Speed) terminal.
Problem is, I have no idea how to do that. The pump runs and water is moving, but it's constantly on High Speed, thus negating the energy efficiency. Any assistance would be gratefully accepted.

    I have a Polaris Sol 1000 Control Panel, so I presume I would need some additional components for that panel?

You will need a two speed time clock to really take advantage of real energy efficiency savings. Intermatic makes one that fits in place of the original t104 time clock. You will need to run an additional wire to the pump as well. You will have the ground. Then one common wire that is always hot whether or not you are on high speed or low speed. You could make this a white wire. Then a black wire for your high speed that is energized in high speed and a red wire for the low speed. It is important that the high and low speeds not be energized at the same time, otherwise you will hear a very unpleasant sound coming from the motor, and failure and shortened life of the motor will be realized.

    I do not know the Sol very well, although i have heard of it. It is not common in my neck of the woods (so. california). However, most automation systems have some specific way of controlling a two speed pump. Jandy for example, probably the most popular automation system, requires the additon of a special 2-speed pump relay. Unless your comfortaable working with electricity and understanding electrical schematics, you might want to consider farming out the installation. Aqua Logic controllers, another popular controller, do not require the additon of another seperate relay, but require the controller to by wired a certain way and configured to recognize the installation of a 2 speed pump. In all instances, if you are going from a single speed to a two speed, you will need to add another high voltage connection from the controller to the pump. You should condult the installation manual that came with the Sol when you purchased it. I am not sure if that unit is still manufactured, however, you should at least be able to download an installation manual if you cannot find yours. Good Luck.

Just replaced a Hayward 2hp pool motor with a OA Smith 2hp pool motor and when i turned it on it starts to switch between high and low and it shuts off. the motor makes a tic tic sound. What do you think...


Hello
No there is no switch in the motor.Correct voltage is done by hooking up incoming power to a combination of internal wires or contacts.

There should be a wiring diagram on the cover where the hookup is.Or on the outside case of the motor.
The high and low speed doesnt make sence to me.Check the rpm of the motor it should be one rpm continueous.
Unless this is a Hvac motor and not a pool pump motor.Possible you may have been sold the wrong motor.
Usually a pool pump is 115 volts 1 speed and 1 rpm continuos duty.Unless you specify 230 volts.

My pool originally had a 2 speed AO Smith pump motor. Several years back it was replaced with an AO Smith single speed motor. I am replacing that motor with a new AO Smith single speed Centurion Switchless...


Is it going to run on 230V then? If so you would normally use red and black. The white wire should be a neutral and the ground wire is obviously ground.

Do you have a meter you can use to confirm the voltage between the wires? If you do you'll want to start with red and white since you seem to think black was not being used before. If the voltage reads 230 and the motor is set up for 230 then attach one wire to L1 and the other to L2...it will not matter which is connected where as long as one is on each terminal. Insulate the black and ground the ground lead to the motor ground screw.

If the voltage is not 230 between those two check between red and black. If that is the 230 then insulate white and put red and black to L1 and L2.
