Existing Systems
Most R-12 systems can be easily converted to Forane® 134a with little modification due to the close characteristics of these two refrigerants.
Retrofitting car air conditioning systems
Technicians should check with the particular equipment manufacturer before performing a retrofit. The following instructions should provide a general overview for retrofitting an R-12 system to Forane® 134a.
-
Inspect the mobile A/C system, checking for leaks, component problems, etc.
-
Recover the existing R-12 charge.
-
Recover the existing lubricant to a level satisfying the equipment manufacturers recommendations.
-
Replace the filter drier.
-
Evacuate the system.
-
Charge the system with a lubricant compatible with Forane® 134a (Usually POE or PAG oil).
-
Charge the system with Forane® 134a with approximately 80-90% of the original R-12 charge weight.
-
Inspect system for leaks.
-
Identify the system indicating it has been retrofitted to Forane® 134a.
-
Verify the system performance.
Using Forane® 134a provides the user with the most efficient and cost effective refrigerant choice in mobile air conditioning applications.
