My 535 is not blowing cold. I checked the "codes" - and I have an 801225 code saying "Compressor : shutdown due to low pressure in the refrigerant circuit".

I realize that it likely has a leak somewhere, but was looking into recharging it for the short term.

The hood label indicates it's 134a refrigerant, but it seems we can't buy any longer in Canada. They do have R12a (the "a" being significant), and they say that it's a direct replacement for 134a, but I also read that it operates at a lower pressure. I am wondering it that might cause an issue with the pressure monitoring and could cause a problem with the compressor (and it being shutdown if the pressure is lower than anticipated with 134a).

Any knowledge out there would be appreciated.
