General Procedures

Automatic Calibration Halogen Leak Detector
Manifold Gauge Set
Refrigerant Identifier
WARNING:
WARNING:Good ventilation before leak detection is necessary in the area where it is to be performed. 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. While leak detection air movement must be prevented.
  1. CAUTION:
    CAUTION:The refrigerant identification equipment must be used before the manifold gauge set is installed, otherwise the manifold gauge may become contaminated. Contaminated refrigerant must be disposed of as special waste. The manufacturer's instructions must be followed when working with the service unit.
    NOTE:
    NOTE:Both manifold gauges should indicate 4,1-5,5 bar at 24°C with the engine off.
    Attach the manifold gauge set to the service gauge port valves.
    1. For the leak test, close the manual valves on the gauge set.
    1. If little or no pressure is indicated, charge the system with approx. 300g of refrigerant.
      For additional information, refer to Air Conditioning (A/C) System Recovery, Evacuation and Charging in this section.
  1. Use 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.
  1. If a leak is found, recover the A/C system.
    For additional information, refer to Air Conditioning (A/C) System Recovery, Evacuation and Charging in this section.
