R22 low side pressure at 70 degrees.
MO99 Retrofit guide. The low side pressure with MO99 will be a couple of psi lower than R-22 while the high side (cond) will be slightly higher than R-22. The MO99 retrofit guide has a lot of useful information, including proper setting of superheat and subcool. It seems 15°of SH and 5-7° SC would be adequate.

All buses work at 70 psi low side. How do they make it happen, thanks. Reply: Matthew: The low side pressure when the compressor is running is a feature of the compressor's own pumping power combined with the properties of whatever device is being used to meter refrigerant into the system. That creates the pressure drop between high and low sides.
*Red Italics Indicate Inches of Mercury Below Atmospheric Pressure Saturation Pressure-Temperature Data for R407C (psig)*The needle valve may also get stuck partially open from grit or a sludging condition in the oil. This will cause high pressure to go directly into the compressor's crankcase causing high low-side pressures and low high-side pressures.
