Charge with 134a between 70-80% of the original R12 charge amount. Note: Hot gas valve will need to be adjusted during the charging process to properly adjust the low side by-pass pressure to 20psi. Replace any O-rings with 134a compatible.
Can I replace R12 with r600?
R600a is a good replacement for R12 With regard to R600a, it has a lower molecular weight, 58.1 kg/kmol in comparison to R134a, 102 kg/kmol, which results in a lower charge for Isobutane. R600a also has lower operating pressures than R134a, improving reliability and extending life of the compressor.
