Sorry for your loss RoBo, My she rest in peace!
Check all your wiring, contactor points, and the terminals at the compressor.
That's 2 screws too many for today's helpers!
Trane was crazy setting the 2 coils back to back, They should have made a 1 piece condenser with the 2 circuits. I come across this problem a lot. It looks clean on the outside but when you separate...
It's up to $ in New York!
I believe the people who own larger R-22 systems will go with M099, most manufacturers are going with 410A. Other manufacturers are using 407C.
We will just have to wait and see what happens.
Then you should be good to go tomorrow.
Your employer is supposed to supply the hi tech gadgets!
Looks like a 15 or 20 ton Trane Voyager, I hope you disabled the compressor from running. If you didn't it will still look like this in the morning!
Old School, I worked for a company back in the 80's and we would evacuate the system with the compressor, we never had micron gauges!
Maybe their using 100% outside air. I have a few units here in NY like that.
Check the voltage being supplied, power companies like to drop the voltage on hot days. When they drop the voltage your amperage goes up causing all kinds of problems.
They had centrifugal chillers in the basement with the condenser water from the Hudson river. They are setting it up the same way with the river water.
Chuck that's good to know, One of the guys I work with told me you lose a ton of capacity. I will let him know tomorrow that would be the case if it was a 50 ton machine.
I heard you lose a ton of cooling, if you had a 5 ton unit after drop in of MO99 it will now be a 4 ton unit.

Their always coming out with different refrigerants, remember freon is Duponts brand name for refrigerant.
What type of stat are you using? Is it a programmable?
3 of the 5 wires get wire nutted and then you will have 2 for hot legs.
Check all your electrical connections at the starter, make sure everything is tight. Then check your connections at the motor. One loose wire will cause the overload to trip.
Change the liquid line drier, restriction will cause the unit to pump down into a vacuum.
Do it right, recover the refrigerant you don't want to be responsible for blowing the charge. With the price of refrigerant your boss don't want to hear you lost the charge.
Check out Stulz, they are making pretty good machines.
Electric heat gun works great on melting ice on coils and pans.
