R-12 Freon is a refrigerant for your motorcar's A/C action.
Provided your vehicle was manufactured before 1993, its air conditioning step feasible uses Freon as a refrigerant. Over extent, Freon can leak from the air conditioning operation, causing your A/C to closing working. When this happens, your method needs to be recharged with refrigerant. The Environmental Safeguard Agency strictly controls the sale and handling of R-12 Freon. Handlers must be certified by the EPA to obtain or stock R-12 Freon. Before you can recharge your own R-12 transaction, you must attain a licence from the EPA showing you carry been trained to employ R-12 Freon.
Instructions
1. Compass a licence from the Environmental Safeguard Agency certifying you to pay for and hilt R-12 Freon. A list of certification programs is on the website of the United States Environmental Protection Agency. Choose one in your neighborhood that suits your schedule. Complete the certification program. Take your license to an approved R-12 reseller and purchase Freon as needed.
2. Park your vehicle, and open the hood. Locate the R-12 service fittings. The R-12 low-side fitting is a 7/12-inch threaded pipe near the refrigerant hose that connects the accumulator to the compressor. The R-12 high-side fitting is a 3/8-inch threaded pipe near the refrigerant hose that connects the compressor to the condenser.
Store the Freon in a safe location for your next use. Close the valve to prevent refrigerant from leaking from the service hose. Attach the opposite end of the service hose to the R-12 low-side fitting on your vehicle. Turn on your ignition, and set your air conditioning system to maximum settings.
4. Position the Freon can so it is upright, and fully open the valve on the service hose. Monitor the pressure gauge on your recharge service hose. Close the valve on the service hose once the pressure gauge reaches an appropriate reading. The R-12 low-side reading should be between 25 and 40 PSI.
6. Disconnect the service hose from the high-side service fitting. Do not release any R-12 Freon into the atmosphere -- this is illegal. Turn off your ignition. Monitor the pressure gauge on your recharge service hose. Close the valve on the service hose once the pressure gauge reaches an appropriate reading. The R-12 high-side reading should be between 200 and 225 PSI.
5. Disconnect the service hose from the low-side service fitting. Connect the service hose to the high-side service fitting. Open the valve on the service hose to allow Freon to flow into the high-side fitting.3. Connect the recharge service hose to the can of Freon. Open the valve on the Freon to allow a small amount of refrigerant to fill the service hose.
