Product Description

 Premium-Efficiency 2-Speed Pool Motor with Integrated Timer

A. O. Smith’s new 2Green two-speed premium efficiency replacement pump motor with integrated timer packs tremendous value into an easy to- nstall package. Energy efficiency continues to drive the needs of the pool market, from legislation to increased awareness of energy costs and environmental impact. And thanks to the 2Green’s energy efficient high and low speed windings paired with an onboard timer interface, energy consumption can be reduced by as much as 58% over single speed motors. The all-in-one integrated motor and timer means less work for an installer and maximum energy savings for pool and spa owners. A. O. Smith’s 2Green is Title 20 compliant** and best of all, there is no additional wiring required for new construction or retrofit installations!

**California’s Title 20 legislation states that pumps > 1HP (total) must be 2-speed or variable speed, and must have a control to default to low-speed (i.e. timer)

Will this motor fit my hayward super pump 3/4 hp?

A  Answered on 5/6/2015 by InyoPools Product Specialist Patrick P.

Yes this motor will fit a Hayward 3/4 HP Super Pump but can only be wired 115V, so if you need to wire 230V then at this time there is not a digital speed motor available.

Does it work on Above ground pool (without damaging the pool liner) And does it come with a normal 115v outlet plug so we can plug it to a GFI outlet ?) we don't use outdoor breaker box.. we only have a 115V GFI outdoor outlet. Lastly will it fit Jaccuzi 2 speeds 1hp pump ?

It doesn't come with the cord but it would fit your jacuzzi above ground pump.

Cab it be used as replacement motor for a hayward pump.

Hi Carlos, This motor can be used on Hayward pumps. If you can provide the pump model and or motor mod I can confirm if this motor will be the correct replacement.

Would this motor replace the HAYWARD A O SMITH MODEL #C48K2N143B1? I have a rotary timer - would I have to take this out in order to install this motor with digital timer? Is there any additional part I ought to get along with this?

A  Answered on 9/13/2016 by InyoPools Product Specialist Lennox H.

Hi Nadine, This B973T motor can be used as a replacement for the C48K2N143B1 motor if you have 115 volts. If the motor is the only item being powered by the timer you can remove the trippers and wire the motor to the timer just for power. I would recommend replacing the pump seal and o-rings but we will need to know the model of the pump in order to locate the correct seals.

I currently have a Hayward Super Pump (SP2610X15) with an AO Smith 1.5 HP Motor (C48L2N134B1) and am looking for a variable speed replacement. Would this pump do the trick?

A  Answered on 3/29/2017 by InyoPools Product Specialist Lennox H.

Hi, Gokhan. The B973T motor is not a variable speed motor, it's a dual speed. The ECM16CU along with the Hayward Super Pump Tune Up Kit GOKIT3 or GOKIT3SALT would do the trick.
