ordered a compressor from a trustworthy source and its shorter than the original.

original is : HRM058T4LP6

New is : HRM058UU4LP6

its about 2 " short in height "atleast"

Pipe sizes are right, and line up.

I got it raised on 2 x 2 blocks. Before I continue, I need to verify the tonnage is correct before I continue to lock this thing in....

Cuz I'll send this bch back in heartbeat if it aint right and collect OT on something else here in the plant.

My wife is already pissed at me ...make it worth my while.

Step #1 Get in touch with the Manufacturer...NOT the person you
bought the Compressor from! And find out what the different
Model Numbers mean.

I remember running into a Lennox Hot/Cold Deck RTU that had original Compressors with internal Suction Accumulators that ran at 0* Superheat. You could keep your hand on the discharge line!
The replacement Compressors did not have the Accumulators and required the TEV/Distributors to be replaced to run at 15* Superheat.
Couldn't keep your hand on the discharge line then!
Good Luck.

The difference is the Application Envelope.

The T - is optimized for 45/130°f

and

The U - is optimized for 45/100°f

I e-mailed you the .pdf with more info on these compressors.

What does UU mean?
Ask the Manufacturer why they are different heights.

My guess he had fat fingers and hit the "U" twice. I don't see any listing for a "UU". I'm sure Tommy can clear that up.

Understood...you're probably right. Didn't think of that.

I'd still be going to the Compressor Manufacturer's Tech Support for the answer.
