How do you actually do the retrofit with the Interdynamics kit?
• EVACUATE the R-12, if there is any left in the system. This must be done without venting (releasing the gas into the atmosphere) by a certified mechanic using approved R-12 Recovery equipment. Many installers will do this without charge, because the R-12 they recover from your system is valuable. • Attach Adaptor to the low-pressure port: [photo]The low-pressure port usually has a blue or black dust cap and is located on the larger diameter tubing that runs between the evaporator (in the dashboard) and the compressor (see question above, “How do I find the low-pressure port?”). Remove the dust cap . Attach the adapter to the low-pressure port. • Charge the System: [photo]Assemble the hose and refrigerant can. Be sure the engine is operating and the A/C is set to maximum cooling. Proceed to charge the system. • Check Pressure & Attach Label:Measure the system pressure at any time by closing the can valve. Refer to the pressure gauge chart for refrigerant level. Confirm proper pressure
