From all brands Trane labels and schematics are the worst, most will fade out in the first year. Nice vid by the way 👍

[@subcoolHVAC]

Yep, the schematic is the mercy of a ziplock bag on the inside panel.

[@joshuaricks7730]

Word of advice.....you really have to set fan correctly with those microchannel evaps. They will drip water into the space if it was a vertical config. With this being horizontal, you still will get water in the evap section if not set correctly.

[@subcoolHVAC]

Thanks for the advice 👍

[@joshuaricks7730]

@subcoolHVAC you do great work brother. Love the channel.

[@subcoolHVAC]

I appreciate that 👊

I'm installing a 7.5T split where I work now. Didn't know you had to have an option module just to use the strips. They didn't say anything when we got the quote. With Reliatel, all you ever had to do was cut the jumper to enable them.

[@subcoolHVAC]

@@topher8634 yeah, I had to remove the jump and install on P4 and from P5 to the OA module P5. First time dealing with Symbio but from what the Installation sheet looks like what they want.

[@Jeremy-gt8xf]

Symbio is the epitome of overly complicated controls & poor QC.
Haven't had a single startup that didn't have a factory issue.

[@subcoolHVAC]

@Jeremy-gt8xf I fully expect some type of issue , might be installer error on my part 😂

[@brushben22]

I have that same unit at a facility, we have changed the ECM motor twice in 9 years. You need to remove the top, get a ladder and spend a ton of money to get that motor. Worst thing Trane has done

[@subcoolHVAC]

@@brushben22 I fully expect that since one of the items listed in IOM is supply fan failure if not up to 30rpm within 40sec it shutdown.

[@erniejack3723]

do the 454b regs go with commercail applications ???

[@subcoolHVAC]

Residential/light commercial Any manufactured after January 1, 2025 will be A2L, dealers can sell r410a units mfg prior still . Trane will use r454b from what I understand

[@EverythingHVACR]

Yessir 454B with RDS mitigation

[@davidnull5590]

Wooo, those are expensive Trane 8.5 Ton Precedent Package Unit, the ones I can easily find are around $11,600 plus shipping. At that price they better last a lifetime.

[@subcoolHVAC]

@@davidnull5590 Yeah, that’s a good estimate. Is 10 years asking too much 😉

[@abdullah_q8171]

Both compressor are deference 1 is big than other why ?

[@colossalsky]

There probably different stages, or one is a compressor and one is a receiver.

[@subcoolHVAC]

2 stages

[@davidnull5590]

If I remember correctly, one compressor is about 1/3 of the cooling (maybe a little bit more); the other compressor is about 2/3 of the cooling.

[@polishsharpshooter2876]

Absolute trash. God speed my man.

[@subcoolHVAC]

We’ll never be without work
