Which circle should I watch with R22 plus, and which lap should I watch with the additional 410A?
The temperature of R22 looks at the red inner ring,The pressure of the R22 value corresponding to see the outer black value (35kg/cm - =3.5MPa is 10 times),The pressure values are all on the outermost ring, regardless of the medium;There are four kinds of media in the red circle and blue circle, which are the temperature of the corresponding medium under the same pressure.
Are you sure there is a 410A display? You can't see it on the meter. R22 just look at the outer ring.
Look at the same place! Just the pressure is different! R410A pressure is higher than R22! Look at the outermost black circle! R22 from 4.5 to 5Kgcm2. R410A added 7.5 to 8KG/cm2 is almost the same!! No matter what refrigerant is different, only the pressure will not change.
