could you explain that a little more please?
could you explain that a little more please?
so your saying namplate means nothing?
how would normal symptoms of overcharge not apply?
like i said .. LITERALLY 10 sec. or even less and the compressor goes off on high pressure .. and its seem to equalize quite quickly after power is disconnected. so a clog seems too far fetched and overcharge seems that way also ..
uh.huh.. thanks.
I'd probably install a schrader fitting just before the evap to make sure it was the evap coil or manifold header that was restricted, and no the condenser coil.
Im not saying its overcharged but it sure sounds like a overcharged micro channel.
Had a lennox a week ago do the exact same thing. Trip almost instantly on HP becausebI fot distracted while adding 410.
It doesnt sound like a compressor issue. It can pump to over 600 psi.
Starting off with a partial charge is a good idea.
SIX.. are you saying that the 410a that came with unit was too much?
circut 2 is on plate for 7lb
i pulled out total 6.10...
replaced lldryer .. blew nitro... vacuumed 500. microns...
charged at plate...it was exact same situation.
what exactly was the charted you pulled out.?
can i ask for anyone to help me with the parts manifest for this unit ..
i am having trouble finding it on the trane website..
ycd240f3haaa
i prefer not to give serial.
and no .. i didn't steal it. haha
i cant give this situation a rest..
f@#$ing spending my sunday basically still working , trying to find anything thats gonna help
thanks.
don't know yet ..
i was hoping to find some kind of breakaway diagram.
the tech from trane said that the orifice's are in the evap. and that there is no other metering device..
i just wanna see for myself ..
Carrier had a similar problem. They had issues with driers clogging on 410 systems, luckily they were using standard coils.
You probably have a case of poor workmanship at the factory. The system may have been open for a while during assy.
The poe oil probably coagulated and is blocking the condenser.
The only way for pressure to climb that fast is from a discharge blockage.
If you have a port on the liquid line and one on the discharge, I would be looking at the pressure difference between the two. They should be within 10 psi from one another.
If there is no liquid port, I'd add one.
My hunch says you will be replacing the condenser coil.
thank you veryvery much jim..
i owe you a beer
No. If its got a micro channel and orifices it wouldn't take much to overcharge.
But since you weighed everything back in then this doesn't sound like a overcharged unit.
I would be welding in taps on the liquid line if it doesn't already have them. That way you can confirm pressure drops through the condenser coil.
