My Lennox 5 ton / LRA 125 / RLA 26.4 runs without issues on my 22kW NG.  I did order a Sure Start from Ziller today for it because I had a $ windfall, otherwise without it, she ran fine.  Incandescent lights do dim a twitch on start.

Well, my battle with Lennox that was partially fueled by what I learned from here has settled out of court before I could even start to take it there.  I had a Merit 5 ton installed on July 7th.  See picture above.  The SES6 Hard Start melted 45 minutes after the unit went live.  You guys told me it should never have a hard start so I attacked with that.  They came back, in writing that they recommend a Hard Start.  Took a little wind out of my sail.  The local installer, very large firm, puts them in on all the larger units.  A cold call into a competitor, they do the same.  So my battle shifted to soot damage, potential damage to compressor or other parts yet to be determined.  Lots of finger pointing.  The installation company is upping my labor warranty to 10 years from 1.  Lennox is upgrading the parts warranty to 15, from 10.  The supplier that provided the Hard Start is paying me $500 for my troubles.  And they are reimbursing me for a Sure Start since I wasn't about to take another Hard Start, so tonight I finally got that feel good moment where I was able to throw money in the direction of Ziller who has helped me keep my sanity during my self-install of the 22kW.  Ziller, it's order # 9105 .... I may need some hand holding on the install.  LOL.

Making this its own thread

The Sure Start will require about 8-10 starts to learn the characteristics of the motor and settle in to provide the best LRA reduction

Hard start capacitors are dirt cheap.  Soft Starters cost around $250-300 depending on size.  It's the time old question, Do you want done right or Do you want done cheap?

Hard start capacitors INCREASE the starting current, and the motor torque, to get a stubborn motor to start turning.  That is the exact opposite of what is needed in this case.

This single ferrule was included with the SureStart.  Just one in this ziplock bag.  Why only one?  There is another sheet, call it an addendum that talks about crimping the ferrules correctly.  Why if they want to use ferrules, do they only include one?  Or is it for something else I'm not quite understanding?  Anyone install a SureStart recently familiar with this?

I just installed my 5th SureStart a few weeks ago, and that box was the 1st box to have ANY of those "ferrule" doohickeys in the box.  The other boxes had zero of them, which is strange because all 5 of them were bought at the same time.  I put them away in my hoarder's box and wasn't really sure in what circumstance they should/could me used.

Ferrules are used when stranded wire is to be clamped under the end of a bolt to guarantee that all of the strands are carrying current.  If a couple of strands get missed by the bolt that becomes a point of heat generation because the connection doesn't meet the rating of the wire.

It's installed and my house is cool.  Only had one moment where I wasn't sure where a wire went.  Step #9; Attach the black wire to the compressor common on the "T" side of the contactor.  I found a bunch of wires that were black and on the schematic were commons, so I plugged it in there.  In the picture below, I plugged it in where the black arrow goes.  But to the left of the contactor, but attached to it is that black wire and there's another flat blade connector below it, obstructed by the angle/view/wires.  Not sure what that is.

Final Job, after testing.

The black wire with the blue arrow is 24 volt control, it is the common of the two conductor from the furnace, when the thermostat calls for cooling the 24 volt coil inside the contactor is energized and pulls the contactor closed.
