Product Description

V-Green™

Versatility and performance best describe A. O. Smith's new V-Green™ variable speed pump motor with integrated timer. Capable of delivering superior energy savings of over 80% versus a standard single-speed motor, V-Green motors are well suited for pump applications ranging from 3/4 - 2.7 total horsepower (THP). Spurred by consumer interest in energy-saving products and government-mandated efficiency standards, the innovative V-Green variable speed ECM offers premium efficiency boosted by such features as Power Factor Correction, which raises overall efficiency while reducing input amps!

Smith's V-Green is Title 20** compliant and with three user-defined variable speeds is a superb choice for reducing energy consumption, for lowering overall pool ownership costs, and for satisfying regulatory requirements.

I have a 1.5 HP Pentair Whisperflo pump. The motor is shot and i am considering replacing the motor with this one. Is it compatible with my pump?

Yes, you can switch over to this Variable Speed motor and should bolt right up to your Pentair pump.

I want to replace my K48M2PA105 pump motor (which is close to dead) with this unit VGreen ECM 27SQU but I see that it is a 56Y frame. Is this adaptable to my existing pump (48Y)? Also my existing motor is a 2HP while this unit shows max rating of 2.7. Is this the appropriate HP to replace the old 2hp single speed? Thanks

This VS Motor would be a fine alternative. 56Y frame Square Flange motors are 1/2" wider (body diameter) than 48Y frame with Identical hole Spacings on the Flange. They are inter-changeable. The 2.7 HP of the ECM27SQU is the MAX it can run. You will decide, when setting it up, how powerful it will be. That is the nature of the variable speed.

I want to replace my pool pump motor, A.O. Smith USQ1202, with a high efficiency variable speed motor. What is the recommended motor and do I need to replace the impeller also?

A  Answered on 3/24/2015 by InyoPools Product Specialist Robert M.

Hello Tom - The correct variable speed motor would be model ECM27SQU. The impeller would not need to be changed.

I have a Hayward Super II Pump Model C48M2N111A3; which variable speed pool pump is a compatible replacement? Also, what else would I need for installation? Thx

A  Answered on 4/22/2015 by InyoPools Product Specialist Lennox H.

Tom, P/N B977T will be the correct motor based on the model number you provided. You'll also need GOKIT2. You can reuse the other parts like the impeller, diffuser etc. if their in good condition.

Hello Jim, The Hydramax II requires a circle flange motor which would actually be the ECM27CU

Needed to upgrade my single speed motor to a more energy efficient variable speed.

Written on 11/7/2019 by Guest

I first contacted INYO Pools and spoke to one of their friendly customer service representatives who assisted me in the selection of the correct replacement motor to fit the existing pump. The service representative ensured all my questions where answered and went beyond a step.

Once I received my variable pump my V-Green 2.7 HP Square Flange 48Y Variable Speed Motor - ECM27SQU, The step by step DIY video that INYO Pools provided me was great. Mind you, this was the first time that I have done something like this. The entire process took me about an hour and half to install.

Interface Control would not power-up or function

Written on 4/1/2017 by Guest

The V270 Green manual is incomplete. There is no mention in the User Manual of the micro-switches adjacent to the 4 pin communication connector in the terminal box or of their function. Once the internal plastic cover is removed (Figure 12 ) four white switches can be seen in a "red" mount. All four of these switches must be in the "on" position for the User Interface to function. My unit came from the factory with switches in the "off" position. After numerous discussions with supplier technical people who were also unaware of these switches it was determined the number 1 (power) switch should be in the "on" position. However, having only switch 1 on does not work. All four switches must be in the "on" position. The User Manual should be updated to indicate these switches must be in the "on" position. I assume some units may come from the factory with these switches "on", and therefore there would be no problem.

Old pool was.costing too much to run

Written on 2/13/2017 by Guest

My old pool pump was running a 2 horsepower Century A o smith motor. Taking the old motor off was straightforward. Turned off all power running to the pump. Opened the pump strain error to clean it out and release pressure. I took a ratchet and loosened the bolts on the housing. The old impeller was 1 hp and missing the retaining screw on the end. All I needed to do to pull the old impeller of was to lock the old motor with a wrench. The old impeller was warped from overhearing at some point. I replaced the impeller and the shaft seal fairly quickly once I got the bolt to hold the impeller in. I just took over servicing my pool myself after letting go of my pool man, and there have been many things that I've found that have been done over the years to this system. Imstallation was simple, I suggest hooking up the wiring first if your clearances are tight to make things go smoother. Lubed up the o rings and boled the motor/impeller/diffuser all into the pump housing. The most difficult part was getting the wireless interface that I bought for the whole unit to communicate properly. After installing this motor my pool is crystal clear. I will update with savings in 2 months.
