The Informant Refrigerant Leak Detector
Maintenance
Maintenance
By following the procedures outlined below, The Informant Leak Detector
will provide many years of trouble-free and dependable operation.
Routine Maintenance
• Replace the batteries per Section
Battery Installation
when the
LO BATT
LED glows.
• Periodically check the detector’s sensitivity by exposing it to a source
of refrigerant gas. DO NOT check sensitivity 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 sen-
sor.
• Routinely check the probe
fi
lter. A dirty
fi
lter will lengthen the detec-
tor’s response time, or prevent the detection of gas if the
fi
lter has
become clogged with dirt or covered with water. A dirty
fi
lter will also
shorten the life of the sensor, as the result of not allowing enough air to
pass over the sensor to keep it cool. Replace a dirty or clogged
fi
lter per
Section
Probe Filter Replacement
.
• Keep the detector case and probe clean by wiping them with a shop tow-
el. 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.
