I am looking for some help with wiring, I am trying to build an exhaust fan for my shop using a fan and capacitor from a old 220v window unit. Unfortunatly my friend scrapped the unit before i could look at how it was wired. My main question is that this is a three speed motor (motor wiring diagram is in ledgible shape) when i wire this i want to run high speed only. Do i just use the BLK-Hi speed wire or all three? Also the capacitor is a Digital-Tech with four sets of terminals, two sets are marked FAN and the other two are marked HERM. There is no terminal marked COMMON which is what i am used to seeing.
Can someone give me some guidance on how to wire this so i don't smoke the motor?

 

Post pics of the wiring
Also , you named your thread 'John M.' )

 

Thank you for your quick relpy, as you can tell i am new to this. I have attached a photo of the motor wiring diagram and of the capacitor.
Any help will be greatly appreciated.


Thank you,
John M.

 

Hmm i've never seen this kind so I can't give you a reliable answer . Better wait for someone abit more experienced to give an input on this

 

Are you seriously asking for wiring advice on 370vac system from anonymous people over the Internet?

I would hope my kids are smart enough to hire an electrician if they weren't trained to handle this. I hope you will hire an electrician too.

 

Thank you, I joined this forum to ask for help from friendly and Knowledgeable people. Apparently you are neither! But thank you for your reply anyway.

 

Shagas, Thank you for taking your time to look at this. I appreciate your courteous and honest reply. Again Thank you, John

@John - I'm pretty confident that you would want to wire only the black wire. Even if I'm wrong, I'm pretty sure doing it this way, you run less risk by not shorting windings together.

Anything I say here should be verified by our resident appliance McGuyver.

 

Use only the black and orange wire. If you think the capacitor is OK, you can use the yellow wire instead of the orange. Someone confirm me on this, but I'm pretty sure that's how it is.
