Carrier Air V

That's right j-d thanks for all your help

OP emailed me a couple pix. Showed PTC and Capacitor. Looked like PTC gets removed and SPP6e directly in its place.
Right, Coach?

Here's a pic I have of a Carrier-

I got "404" errors on both url's at least with Chrome on my phone.

Hope this works j-d

Now... Is the PTC actually present? On the unit? If yes then remove and install SPP6e to those lugs. If not... Do you have an unused lug on COM?

Yes found Schematic showing PTC

Then, rc, you should be finding a PTC device across the COM (unmarked) and HERM (compressor run). A little bakelite or ceramic looking device. The diagram I found says there is one and there's no note saying it's optional.

Can you check that?
Did you find a wiring diagram and does it show a PTC?

If there is NO PTC, then that one HERM terminal wire should trace to Compressor and all you'd do is add the SPP6e:

With POWER OFF, first short COM and HERM, COM and FAN. Find a secure place for the SPP6e and run its wires toward the Capacitor.

IF THERE ***IS*** a PTC, Then find the leads from the PTC and Wiggle/Pull them off COM and HERM. Replace with the two wires of your SPP6e. Secure the SPP6e in place and you're done. Button'er up and try a test run.

Sounds like the compressor IS PSC as you were told, but that for some reason there's no PTC device as shown in the diagram in that manual I found.

Agree with F-J.
Just want to make sure OP has what we think is there.

Followup - In this picture, there are three sets of terminals. By "set" I mean within a black insulator.



In your A/C, does each "set" have at least one wire on it? I think you'll find a PTC Device across HERM and COM. If that's how yours is, check the SUPCO instructions against that information.

Yes on my capacitor it has at least one wire to each set of terminals. What I was trying to say that on the herm terminal
there is only one wire going to it so I can run a wire from the hard start capacitor to the empty one. The only other terminal
that has a empty one is the one marked fan.
