Would be a great application for chilled water but that stuff is pricy hahaha
Building has 52 50 ton trane RTUs. Roof is standing seam.
Had a in house maintenance guy.
Here is today's unit
Needs some electrical tweaking
Along with this
A couple of these
4 condenser fan motors
Few blades
Box of assorted other stuff
Also unit needs nu brite bath for evap and cond. Oh yeah no water on roof. Been slow this is great!!

wow.....how big is this building?
That is alot of RTU's!
don't you just love when the flames burn off the wiring schematic?
"Better tell the sandman to stay away, because we're gonna be workin on this one all night."
"Dude, you need more than 2 wires to a condenser to run a 2 stage heatpump."
"Just get it done son."
Dad adjusted
Would be glad to have the flame roasted schematic instead of the massive wiring harness and all the wiring within a 1 foot radius around the two flame throwing transformers that is destroyed.
What's your technique for setting that compressor in place? I have 8 CSHAs to replace on a rooftop and was denied a crane... I have a 40' man lift to get them on the roof but from there is looks like it might be pure muscle.
Here is 3 ways:
1. He-man that thing in there
2. A couple 2x4s making two ramps, roll it up into it.
3. Get straps or chains and go over the top of the unit and hook on the frame on the other side. I try to have it just long enough that a loop of the strap just barely hangs over by the electrical panel. Then I hook a come a long/chain fall/chain hoist to it and lift it in there.
On #2 I forgot to mention use a hand truck to roll it in
Another unit:
Wiring harness in return section caught on fire. Also note the high efficiency filters.
If the building manager will allow it, we use a Genie Duct Jack to get the compressor up to the level of the unit. Then there is less He-Man stuff to do to get it into place. But you have to have a crane or a boom truck to get the duct jack to the roof. We use this technique when the RTU is too far from the edge to use a crane.
Also if it is a flat roof. A engine hoist can be brought onto a roof in manageable pieces. We turned the boom around on ours and counterweight the base. It works okay not the safest way if you don't have enough counterweight.
Holy crap... lots of work for you to do there.
Don't pick the fly crap out of the pepper.
Another one repaired here a couple weeks ago sent to me by a HVAC talk lurking co worker.
Not me hahaha. Guy working on the wire on that one did a good job. I would have had to go to the next unit and robed the panel. Energized it today and it was ready to go (waiting on crank heaters to warm it up). Will run the transfire Trane tomorrow. Started on the third unit today. It is also a transfire Trane! Gah!
soooo...what's causing all the failures??
The return section harness fires are a head scratcher. One even has a melted end of a evap pan.
Also the combustion motors are not fused making the transformers burn.
Tent fared well last night
Sorry about rotation
