Tim,

 

Not sure about the condensor, but you can use the sight glass method to make sure there are no air bubbles in the system when charging. Make sure you replace the receiver/dryer if converting over and the system should be evacuated properly before recharging.

You can use the same condensor and using the sight glass method may overcharge the system when converting over to R-134a.

 

Determine the correct charge for the system being upgraded to R134a use. In most cases, the R134a charge will be 10% less than the R12 charge.
