I have defrosted the coil and checked pressures on start-up and I found that the pressures do not equalize between the high and low sides. I should have included that tid-bit in my first post. The high side reading corresponds with the 404a at room temperature, but the low side pressure corresponds with the 404a being well below freezing.Pressure regulator KVP-16% Check dimensioning 4.

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 ...R600A is a refrigerant grade Iso-Butane that is available as a natural refrigerant. The refrigerant is used in a wide array of applications and is the perfect replacement for harmful refrigerants, such as R12, R22 and other CFCs and HCFCs. R600A is gaining popularity over the years, given its low Global Warming Potential (GWP).High School or GED. 3,469 satisfied customers. Whirlpool 4 door, freezer working, making ice, refrigerator.

ANSWER :B. direct tv stock R-404A rose to prominence in the late 1990’s with the phasing out of CFC and HCFC refrigerants like R-12 and R-502. There had to be a replacement for the Ozone damaging refrigerants of the past and the successor was the HFC R-404A that we all know of today. 404A’s reign however was short lived.Items Displayed in Black shows pressure in pounds per inch gauge.
