Good evening gentlemen.............

Wait till you get to compensator, auto-compensator, Y/Delta, Part Winding and then get a 12 lead motor with no markings that you have to 'phase out' and hook up the Y/Delta then fire it up.... You gotta be REAL careful you don't let the factory smoke out of the windings.....'cause it just about impossible to get back in!!!!
Frankie and HM could probably tell you a story or two about that.....

I've had a little experience with factory installed smoke, too.

...and remember to pray for ARPA, too.

i know all about valence electrons!
but please explain the 156 rule????

i am always ready to learn more??

frank

if you wire up a 60 ton copeland semihermetic part winding start and it makes a funny sound and smokes a little then blows the fuses!!
Go drink 156 beers????????????????????????

Haha well he does have 50 years in the trade. Taught me everything I know electrically. From what a valence electron is right up to the Copeland 156 rule.

i do not know if i told you guys about my last mishap???

40 ton carlyle semi!

new 80 ton carrier split!

low suction high superheat! duh the usual!!!

low amp draw!!! duh!!!

vav system, 6 compressors, 6 unloaders 3 condensers, 18 stages of cooling!!!

I did what any good mechanic would do and added like 200 lbs r22 to get the suction up but eventually my superheat was very low!!!

I finally tweaked a bunch of krap to get it to run well and suction pressure up to about 65 lbs, not bad for a big split fully loaded!!!

ended up with 7.4 degrees superheat fully loaded on a hot day!! ofcourse it is vav with a 150 hp vfd!!!!!!

anyhow as you guessed the next year/ last week!
it shorted to ground,'

changed it and when i disconnected the suction service valve/king valve!!!!!

guess what i found between the service valve and the compressor!!!
from the factory ofcourse!!!!!





A RED 2" PLASTIC CAP!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!!!!!!!!



i think blue oval is going to be paying for this one!!!!!!!!!!!!!!!

i found this once before on a 100 ton trane e compressor but the symptoms were much worse and it was a chiller with a factory charge!!!
so i pumped it down and found it easy!


found another factory similar!!!

carrier 30 rb chiller kept pumping down?????????????????????????????????


keep in mind it is a packaged chiller!!!!!!!!!!!!!!!!!

found a rubber plug from a piece of acr copper stuck right before the EEV!!!!!!!!!!!!!!!!!!!!!!!!!

not so easy to find!!!!!!!!!!!!!!!!!!!

ofcourse first i replaced the EEV!!!!!!!!!!!!!!!!!!!

[supertek65]

i was told this is the biggest motor in the world???

has anybody worked on one bigger???
