Poolside Repair: How to install an energy efficient pool pump motor

January 28, 2020


Hello and welcome to Poolside Repair.
We’re in lovely Orlando, Florida, and my name is Matt, this is Rob and this lovely little guy right here is Dennis, and we’re going to be working
on Dennis’s daughter’s pool today We’re going to be installing
a VGreen variable speed motor and a VLink wireless interface.
It’s going to be a pretty fun day Tell us why we’re going to be
doing that today, Dennis? Okay, she currently has a single speed motor that’s not cost-efficient. We want to replace it
with the variable speed motor, maybe cut her cost down to 50%. And then we have the VLink
that’s going to allow you to kind of control it wherever you are
and be able to track the energy– You can monitor month to month
what the costs are Yes, it’s going to be fun You did great, Dennis,
let’s go check out the equipment. All right, so what we have here is
a single speed Hayward Super II pump As you could probably hear, it’s a little loud,
I mean, which is normal for a single speed pump. Once we get the VGreen on there,
you should notice it’s much quieter. Let’s go ahead and get the installations started. All right. I’m going to start to disassemble it
and take some of the parts off so we’re going to have to reuse them
on the new motor, so I’m going to start with the diffuser. That just pops right off put this to the side, take the wheel ring. Okay, so the next step
would be to remove the impeller, but before you do that,
you’ve got to stabilize the shaft, otherwise, it’s going to keep spinning. We’re going to use a 7/16 wrench slide in here behind the protector We’re going to stabilize and, basically, you just turn
the impeller so that it locks in place like that. And then we’ll spin the impeller off counterclockwise. The seal plate will just pop right off. No critters running out, so that’s good All right. So we’re going to go ahead
and take the bolts out here to get the motor plate. Again, we’re using a 9/6 inch socket. All right. so we got the bolt out
so we just going to take the motor, play it off, and it’s that simple All right. So we got the two motors side by side,
obviously, this is the old one, is the new, the VGreen. It’s the 1.65. You can see the interface here.
The 2.7 has the digital interface All the VGreen motors are
totally enclosed and fan-cooled so it should last longer than
the old single speed. So, at this point, we’re going to start to put on
some of the old parts back on the new motor, minus the shaft seal, you want to make
sure you replace your shaft seal, otherwise, if you try and reuse the old one first of all it can void the warranty and it could let water down
the shaft and ruin the motor. So, you want to make sure place that shaft seal. I slid the motor mounting plate on and on the Hayward Super II, there is a top and a bottom of this plate,
it’ll say top on the reverse side so you know it’s the top Next part is going to be the seal plate. You want to just visually inspect the seal plate,
make sure there’s no cracks, if so, you want to replace it First thing you want to do is pop out this old
part of the shaft seal. You should take a flathead and just
pop it out from the back This one was glued in there,
so I have to get this out You have to make sure you clear out
anything that’s still in there. All right. So We got our cleaned out seal plate We’re going to take the white ceramic
part of the two-piece shaft seal, put it in here. You don’t want to
touch the face of the ceramic, so we’re going to use a cloth to push it in There you go.
And make sure the white ceramic is facing out. Next step is going to be putting the seal plate back over the motor mounting plate.
You can go ahead and remove this shaft protector and discard it.
You don’t need it. Again, there’s a top and bottom to this seal plate.
The grooves are going to be at the bottom to match up with the motor mounting plate. In the next steps, we’re going to be
putting the impeller back onto the shaft. You’ll notice that
the old spring portion of the shaft seal is still on the old impeller.
You got to remove that and this actually,This metal part here this little sleeve is actually
part of the old shaft seal. so, this has to be removed.
That’s not part of the impeller You can just take a flathead
and kind of work that off and this little rubber piece All right. So we got the new
spring portion of the shaft, so we’re going to put that
on the shaft of the impeller. You’ll notice that there’s a shiny side
and a dull side to this spring portion. The shiny side is always going to
meet up with the smooth ceramic. So, I’ll put this on the impeller facing out,
so that it’ll be able to touch the white ceramic. You see the shiny side is out. We’re going to put that on here. Before we do,
we’re going to stabilize the shaft of the motor. If you notice, the back of the VGreen is a little
different from the traditional single speed. You have to use a 5/16 Allen wrench
in there to stabilize the shaft. We’ll just stick that in there and then spin the shaft
until you can tell it’s locked up At that point, we can thread
the impeller back on It just has to be hand tight.
You don’t need to really crank it on there. Just needs to be snug, like when
you’re installing an oil filter on your car Just snug enough. You don’t need to crank it on. We’re going to slide the impeller ring
back over the impeller. The wider side is going to be out
towards a strainer. It actually tells you on this impeller ring,
“Out towards the strainer”. so,The next piece will be the diffuser You can see the old diffuser ring is still
on there. We’re going to discard that. We are going to put a new one on. You’ll see here it says, “Top”, so it’s going to
obviously go at the top of the seal plate. We’re going to put the new
diffuser gasket on there. We’re just going to put a little bit
of silicone lubricant on it It doesn’t have to be much.
Just a little pea-sized drop. Just enough to make it shiny. The VGreen motor will come with
these two plugs installed in the back The one the right here is for the high voltage which should be your power coming into it.
The one on the left is for an auxiliary line. We’re going to use it to go to the VLink,
but if you had automation, you’d use that. If you’re not using VLink or automation,
you would just leave this one in. If it’s loose you want to make sure
it’s tight so water doesn’t get in there. We’re going to go ahead
and remove the high voltage one and put on our elbow. All right. So, now, we have the motor installed,
thanks to Rob. We’re going to move into
programming the motor The motor comes with a factory preset but,
obviously, we want to do our own schedule. The way we’re going to do that
is we’re going to press step one On this side, you can see that it says “duration” over these numbers, and that’s
how many hours it’s going to run for. Let’s say we’re going to run it for four hours. You’re going to press step one.
Then it’s going to take it over to speed. You can see the RPM readings over there Let’s have it at 3100. To save that,
you would just go to step two and let’s say step one. We’re going to do
the same thing for all of these Then once you have step three the next button push that
you do is going to save step three You don’t have to worry about that. Let’s say you want to do an override. If you want to for whatever reason, you want to press
override and have it run for, let’s say two hours and then you’re going to have it
run at 3450, which is full-bore, and that will do the full power of the motor That’s just in case, let’s say,
you want to run the cleaner If you have a suction side
cleaner or something like that, it gives you a chance to run the motor,
to mess with any of the step; one, two, or three. We’ve got the VGreen installed. Next thing
we’re going to install the century VLink the wireless motor interface. We’re just
going to unbox to take a look at it. Basically, it comes with everything.
You’ll need to install it minus the tools. Let’s take a look here.
You got your user manual, you got the actual VLink, and then you have all the other cables
and the connectors that you’ll need. All right, we finished installing
the VGreen and the VLink. Dennis, how do you think that went today?
You think a normal residential owner can do that? Yes. It looks very good.
You look at the video, pay attention to what’s on the video, and maybe look at a couple things in the users
manual and it ought to go very well for you. Yes, and so far with the installation of
the motor and looking at the VLink, it looks like we should save a whole lot of
money coming in the next few months. Yes. We were looking at the app and before, it was costing anywhere, depending on time of the year,
$50-70 to run the single speed pump per month. The app is already telling us this is December, but it’s going to be
running $10 a month right now. You might be looking at $20 a month in summer,
but that’s still a heck of a savings. Yes, so we’ll send you the check.
It will be in the mail and thank you for joining us. -Thank you.
-Bye
