Need help reading wiring diagram

[Darko]

HI everyone,

I have Hayward super 2 pump, and after of years of rebuilding bearings and such i decided to buy new motor, so original motor was sp1620z2,
i replaced with sts 1152r, now, i was used to reconnect wiring on old pump by taking a picture of old wiring, new motor has different set up, i have to figure out which wire is 220 , which one is high and which one is low, i have picture of wire color and diagram thats on the old pump motor.

according to this diagram which one is 220 , which high , and which is low,

on the pump itself there is 1, 2 and it says 3 or 4

The picture you are showing of the wiring shows the configuration on the left is the high speed connections and the one on the right is for the low speed connections. The line 1 and line 2 are the designations for the two 120 lines that make up the 240 for the motor. Looking at the second picture, I am going to guess there is a selector switch somewhere to change the motor speeds from high to low on the current setup. If that is the case then the selector switch is switching between the "2" wire and the "3or4" wire to control the speed.

Thank you Dan,
my pump is dual speed so ill have to somehow put this together, my understanding is that on my picture , red wire is 220 or common line , i just have to figure out is blue wire hi or low speed line , im not very good with electrical stuff.

Red wire is 120v
Blue wire is 120v
Together they make 230v

Depending on if you wire them to terminal 1 and 2 for low speed or terminal 1 and 3 for high speed

this is diagram from new motor
i was thinking connect my red wire to L2, blue to L1, and yellow to A,

is this correct, i guess i just have fear of frying new motor , and also i wonder how will i be able to see if impeller is spinning in the right direction.

 

[jza1736]

Red to L2

Blue to L1
That will give you high speed

Where did the yellow wire come from?
First your mentioning of it
Is that your low speed connection?
Then yes it, or would go to terminal A

 

[jza1736]

There should be a directional arrow on the motor for which way it spins

 

[JamesW]

The motor should spin the correct way. Really no reason to worry about that.

Looking from the rear, the shaft turns clockwise.

Looking from the front, the impeller turns counterclockwise.

I guess that raises the question of how the shaft can turn clockwise and counterclockwise at the same time?

This is correct

motor is not reversible, it will only spin the right way.

Thank you all so much , there is some real knowledge here ,
and yellow wire is from my lower speed i suppose .

 

[Bama Rambler]

You are correct. Yellow wire goes to "A" terminal.
