Tips to Discharge an Automotive Air Conditioner
Tips to Discharge an Automotive Air Conditioner
Instructions
1. Determine that the car's air-Cooling system contains pure refrigerant before discharging, or evacuating the system of refrigerant. Use a refrigerant purity indication tool for this task. This is an electronic tool that connects to the air Cooling service port and reads a small sample of refrigerant. Although most automotive refrigerant is pure, some facilities not qualified to work with air-conditioning may have added refrigerant a contaminated or even flammable system. Recover contaminated refrigerant in a separate container so that it is not re-used. Use a filter in your recovery equipment designed to separate sealers put in the system to stop leaks. These materials can damage recovery equipment.
2. Connect the air-conditioning recovery and recharge machine to the air-conditioning service ports. The low pressure side connector is indicated with a blue cap, and a red cap covers the high pressure side. The hoses on the machine are color-coded the same way. Connect the hoses to the corresponding ports. Note any pressure readings in the system on the recovery machine's gauges.
3. Start the evacuation process. Many air-conditioning service machines are automatic, and you just have to push one button or turn a knob. The pump inside of the machine will start, moving the refrigerant into the machine's internal tank. The pressure gauges will drop as the refrigerant is recovered.
4. Allow the air-conditioning service machine to draw the system down so that a vacuum exists, as shown on the gauges. When the gauges reach zero, the recovery process from the vehicle is complete, and there is no more refrigerant in the system.

5. Allow the system to hold a vacuum for at least 10 minutes. If the vehicle is unable to maintain a vacuum on the gauge, the air-conditioning system has a leak, which must be repaired before the system is recharged with refrigerant. Program the machine to dispense the amount of refrigerant required by the vehicle's system. This is usually indicated on a sticker under the hood. Start the charging process by setting the machine to start. When the process is finished, check the air-conditioner for correct function.
Tips & Warnings
If the air-conditioner is cold, but not as cold as it should be, you can add a small amount of refrigerant using cans sold at auto parts stores. Some of these cans also include a fluorescent dye, which will show up as a bright green color when illuminated by a special lamp. This helps show where the system is leaking.
Do not discharge the system by loosening a hose fitting or removing a hose. This is illegal, and refrigerant fumes can be harmful if inhaled. Do not service an air-conditioning system unless you are EPA certified to do so.
