It is not a drop in replacement on R-22 machines. If you wish to use this product you will need to vacate all of the old R-22 out of the system. This is due to the R-22 systems using mineral oil and this HFC blend using POE oil.

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.

The refrigerant 'starts' as a low-pressure gas and then transitions into a high-pressure liquid as it absorbs the heat from the indoor space. R22 is then sent to the outside part of the unit, where it releases the heat, cools down, and turns back into a gas. R22 has been used in the air-conditioning industry since the 1930s.end), to cut-off at 70 degrees, stage subsequent fans to cycle off at 10 degree intervals, (ex. 60, 50, 40, 30). set all thermostat differentials to 5 degrees. pressure control; fan # 1; (compressor end fan); cut-off @ 175 p.s.i.g.; cut-in at 235 p.si.g.. make sure that this fan cycles off just above the point whereI have a 3 ton condenser. my low side pressure is 85psi/50 degree temp., high side is 415psi/156 degree temp., its r-22 system my wet bulb is 71 degrees, my air temp. at the condenser is 98 degrees,temp. is 72 degrees at the vapor line. that gives me the propper subcooling but the pressures and temps. are too high. 415psi is too high so is ...The main reasons your compressor will have simultaneously low head pressure and high suction pressure is due to: Bad or leaky compressor valves.
