Dear all,

What is the working pressure of R407C compared to R22? ...

For R22, the discharge side is 240psi and suction side is 70 psi. Is it similar for R407C? ...

It depends on the temperature of the refrigerant, check your Pressure/Temperature tables.

ive found the running pressures different. suction pressure 50 psi and discharge 220 psi. but from what ive been told its quite an unstable refrigerant.
