Flame-Type (Halide) Leak Detectors

Avoid inhaling fumes produced by burning refrigerant when using flame type detectors. Use caution when using detector near flammable materials such as interior trim components. Do not use flame type detector where concentrations of combustible or explosive gases, dusts or vapors may exist.

1. Light leak detector and adjust flame as low as possible to obtain maximum sensitivity.
2. Allow detector to warm until copper element is cherry-red. Flame should be almost colorless.
3. Test reaction plate sensitivity by passing end of sensor hose near an opened can of refrigerant. Flame should react violently, turning bright blue.
4. If flame does not change color, replace reaction plate following manufacturer's instructions.
5. Allow flame to clear, then slowly move sensor hose along areas suspected of leakage while observing flame.
Position sensor hose under areas of suspected leakage, as R-12 refrigerant is heavier than air.
6. Move sensor hose under all lines, fittings and components. Insert hose into evaporator case, if possible, and check compressor shaft seal.
7. The presence of refrigerant will cause flame to change color as follows: pale blue, no refrigerant; yellow-yellow/green, slight leak; bright blue-purple/blue, major leak or concentration of refrigerant.
8. If detector indicates a large leak or heavy concentration of refrigerant, ventilate area using a small fan in order to pinpoint leak.
9. Repair leaks as needed, evacuate and recharge system, then recheck system for leaks.
