50 isn't cold!

If you warm the refrigerant container to 70 or so, you will not have a problem. You may not have trouble anyway but it speeds the process if the container is warm. The unit will take it because the low side is probably only running around 60 psi anyway.

I would just like to add that you warm the container using a heater blanket sold at HVAC wholesalers for that purpose. You DO NOT heat the container with your torch rig.

If your EPA and been at it for a time. You should know how you can charge a unit by liquid on the suc. or low side and not blow the compressor. The bottle wont get cold this way so you dont have to heat the bottle. ED
