Post Likes. also keep in mind that with a/c you are dealing with pretty much set conditions, outside 70- 100F , inside 70- 80F. in ref. outside -15--to 100 F, inside -20to 50 f ( typical for my neck of the woods). you really cant just say low temp xxx psi low temp xxx psi. we have to use the pt chart. Reply.Trying to find out the correct way to charge a walk in cooler with 404a. I charged the system to clear the sight glass and then add 4 percent of the total I have put in on top for low ambient but the condenser is inside the kitchen so not sure that really mattered. I have my boss tellino me to charge the system to 20 super heat and 20 subcool. · Re: 404a cool room operating pressures. If it was a 22 system then the Cap, if it is a capillary system, will be sized for R22, not R404a. That's always assuming that it's not a TX system, in which case the TX valve will have to be changed for a R404a valve. Your best bet would have been to drain the poe oil and replace it with the same volume ...Yeah I've got 120 from 1 to 4 on the defrost clock (an 8145-20 Paragon) but 0V from N to 4?
