R410A pressure

[Acrisoft]

Anybody knows the average pressure of a R410A mini SPLIT pipes when the system is OFF
in a sunny day ?

Look it up on a pressure temperature chart, what i might think an average summer day would be different to you in Brazil!

Hi

Here is 28 c approx. 85 F. In table saturation pressure at this temperature is 280PSI.
But i need to know the pressure with system OFF with both sides equalized.

Turn off the system and connect gauges and wait for it to equalize.Record pressure ,job done!!
You really need to clarify the refrigerant involved is it R410A as stated in the thread name OR is it R404A as stated in the first post??

Not to mention the fact that the pressure when the system is off is useless as a measurement of anything useful...

It's R410A. I correct the first post. Thank you.

I was curious about static pressure because the R410A busted the connection flare.

Now I wonder if a normal R410A pressure would be able to do it or only presence of air inside of system
could be able to do it ?

Neither would be able to bust a properly made flare on the correct pipework.

Bearing in mind that it should been tested at 1.5 X Maximum Operating pressure...
