    The Informant™ 2 1. OVERVIEW 1.1. Introduction The Informant 2 Dual Refrigerant / Combustibles Leak Detector (Figure 1) is a portable, battery powered instrument designed to pinpoint the location of either refrigerant or combustible-gas leaks using separate, interchangeable sensors. The type of gas detected depends on the sensor installed.

  • Page 6: Features

    The Informant™ 2 1.2. Features • Detects the presence of either refrigerants or combustible gases (with appropriate sensor installed) • Sensors that represent the latest advancements in sensor technology • Microprocessor-controlled circuitry that guarantees accuracy and reliability • Dual bar-graph LEDs provide visual indication of the refrigerant/combustibles level from a wide variety of viewing angles •...

    The Informant™ 2 2. OPERATION 2.1. Battery Installation WARNING: Explosion hazard. To reduce the risk of igniting a flammable atmosphere, batteries must only be changed in an area known to be non-flammable. NOTE: To maintain agency approval, use only the following types of ‘AA’...

  • Page 10: Refrigerant Sensor Installation

    The Informant™ 2 NOTE: For dual detectors, the red probe tip will not screw onto a probe that has a refrigerant sensor installed. This feature safeguards against the possibility of an operator mistakenly thinking that a detector with a refrigerant sensor is configured to detect combustibles.

  • Page 11: Combustibles Sensor Installation

    The Informant™ 2 2.4. Combustibles Sensor Installation Install the combustibles sensor, filter, and “red” probe tip onto the end of the detector’s flexible probe as shown in Figure 3b. Observe the red color coding on both the sensor and probe tip. NOTE: The Informant 2 is intrinsically safe only when its combustibles sensor is installed.

  • Page 12: Low Battery Indication

    The Informant™ 2 NOTE: During the warm-up period, the detector has zeroed out any background concentration of vapors or gases that were present in the area. After the detector is turned on and allowed to warm up, it is ready to perform leak testing as described in Section Procedure for Locating a Gas Leak.

  • Page 13: Locating A Gas Leak

    The Informant™ 2 2.8. Locating a Gas Leak After the detector is turned on and allowed to warm up, observe that none of the gas-level LEDs should be glowing. Also note that both the probe tip should be blinking and the audible indicator ticking once per second.

  • Page 14: Sensor Failure Indication

    The Informant™ 2 CAUTION: When using the refrigerant sensor, note that exposing this sensor to a steady stream of highly concentrated refrigerant will severely reduce sensor life or damage the sensor. Sensor life is directly proportional to the amount of refrigerant that passes through the sensor.

  • Page 15: Refrigerant Sensor Flooding Indication

    The Informant™ 2 • use the detector in windy areas, • move the probe tip back and forth faster than 2" per second, • allow the probe tip to contact a hot surface. 2.11. Refrigerant Sensor Flooding Indication When the refrigerant sensor becomes flooded with a high concentration of gas, observe that the gas-level LEDs quickly light full scale and then all turn off, leaving both the audible tick rate and probe tip blink rate at elevated levels.
  • Page 16 The Informant™ 2 • Always follow the refrigerant system around in a continuous path so that no areas of potential leaks are missed. If a leak is found, always continue to test the remainder of the system. • At each area checked, the probe shall be moved around the location, at a rate no more than 25 to 50 mm/sec (1 to 2 in./sec), and no more than 5 mm (0.2 inch) from the surface completely around the position.
