Electronic Leak Detection

1. Refer to: Air Conditioning (A/C) System Health and Safety Precautions (100-00 General Information, Description and Operation).

2. WARNINGS:

  • Before starting leak detection, make sure that the area where it is to be done is well ventilated. If the surrounding air is contaminated with refrigerant gas, the leak detector will indicate this gas all the time. Odors from other chemicals such as antifreeze, diesel fuel, disc brake cleaner, or other cleaning solvents can cause the same problem.

    Prevent air movement while performing leak detection.

  • The refrigerant identification equipment must be used before attaching the manifold gauge set. Otherwise the manifold gauge set may become contaminated. Contaminated refrigerant must be disposed of as special waste.

    Follow the manufacturer's instructions when working with the service unit.

NOTE: At 24C with the engine switched off, both manifold gauges should show 4.1 to 5.5 bar.

Attach the manifold gauge set to the service gauge port valves.

3. For the leak test, close the manual valves on the gauge set.

4. If little or no pressure is indicated, charge the system with approx. 300g of refrigerant. Refer to: Air Conditioning System - Evacuate and Refill.

5. Use the R-134a Automatic Calibration Halogen Leak Detector to leak test the refrigerant system.

Follow the instructions included with leak detector for handling and operation techniques.

6. If any leak is found, extract the refrigerant under suction. Refer to: Air Conditioning System - Evacuate and Refill.
