Flame Type (Halide) Leak Detectors

FLAME TYPE (HALIDE)

When using flame-type detectors, avoid inhaling fumes produced by burning refrigerant. Do not use this type detector where concentrations of combustible or explosive gases, dusts or vapors may exist.
1. Adjust detector flame as low as possible to obtain maximum sensitivity. Be sure copper element is cherry red and not burned away. The flame will be almost colorless.
2. Slowly move detector along areas of suspected leaks. A slight leak will cause the flame to change to a bright yellow-green color. A significant leak will be indicated by a brilliant blue flame. Position detector under areas being tested as refrigerant gas is heavier than air. The presence of dust in the pickup hose may cause a change in the color of the flame. If not recognized, a false diagnosis could be made. Store leak detector in a clean place and ensure hose is free of dust before leak testing.
3. Check for leaks in the manifold gauge set and hoses, as well as the rest of the system.
4. Use a small fan to ventilate areas where the leak detector indicates refrigerant constantly. These areas are contaminated with refrigerant and must be ventilated before leak can be pinpointed.
