Leak Test

WARNING: WHEN HANDLING REFRIGERANT (R-12):
- Always wear eye protection.
- Do not let refrigerant get on your skin or in your eyes. If it does:
- Do not rub your eyes or skin.
- Splash large quantities of cool water in your eyes or on your skin.
- Rush to a physician or hospital for immediate treatment. Do not attempt to treat it yourself.
- Keep refrigerant containers of (R-12) stored below 104°F (4O°C).
- Keep away from open flame. Refrigerant, although nonflammable, will produce poisonous gas if burned.
- Work in well-ventilated area. Refrigerant evaporates quickly, and can force all the air out of a small, enclosed area.

IMPORTANT: Do not vent refrigerant to the atmosphere. The chlorofluorocarbons (CFCs) used in conventional refrigerant (R-12) may damage the earth's ozone layer. Always use UL-listed, Refrigerant Recovery/Recycling System equipment to extract the refrigerant before you open an A/C system to make repairs. Follow the equipment manufacturer's instructions.

PROCEDURE
1. Connect an Air Conditioning Service Station as shown.

NOTE: Connect the high-side adapter to the high pressure hose first, then connect the hoses to the car as shown. When testing is completed, disconnect the high-side adapter from the high-side fitting; do not disconnect the hose from the adapter, or refrigerant may escape from the system.

2. Open high pressure valve to charge the system to about 100 kPa (1.0 kg/cm2, 14 psi), then close the supply valve.
3. Check the system for leaks using a leak detector.
4. If you find leaks that require the system to be opened (to repair or replace hoses, fittings, etc.), recover in the system according to Refrigerant Recovery procedure.
5. After checking and repairing leaks, the system must be evacuated.

CAUTION: Use only a R-12 refrigerant Air Conditioning Service Station.
