3. MAINTENANCE
3.1. Introduction
By following the procedures outlined below, The Informant 2 Leak
Detector will provide many years of trouble-free and dependable
operation.
3.2. Routine Maintenance
• Replace the batteries per Section Battery Installation when the
LO BATT LED glows.
• Periodically check the detector’s sensitivity by exposing the sensor to a
source of its corresponding gas (either a refrigerant or combustible
gas). DO NOT, however, check the sensitivity of the refrigerant sensor
by cracking open a bottle of refrigerant or Schrader valve and exposing
the sensor to a stream of pure refrigerant. This will severely reduce
sensor life or damage the sensor.
• Routinely check the probe filter. A dirty filter will lengthen the detector’s
response time, or prevent the detection of gas if the filter has become
clogged with dirt or covered with water. A dirty filter will also shorten
the life of a refrigerant sensor, as the result of not allowing enough air
to pass over the sensor to keep it cool. Replace a dirty or clogged filter
per Section
Probe Filter Replacement .
• Keep the detector case and probe clean by wiping them with a shop
towel. If necessary, moisten the towel with a mild detergent solution.
Avoid using any type of solvents that may either attack the detector’s
ABS plastic case, or leave behind a hydrocarbon residue that may
desensitize the sensor.
3.3. Probe Filter Replacement
The probe filter is designed to keep dust, dirt, and water from entering
into the sensor area.
Replace the filter whenever it becomes clogged as evidenced by the
detector not responding in a positive manner to a known source of gas. If
the filter is covered with water, simply remove the filter and dry it off.
Replace the probe filter as follows (refer back to Figures 3a and 3b).
