1. OVERVIEW
The Informant™ 2
1.1. Introduction
The Informant 2 Dual Refrigerant / Combustibles Leak Detector
(Figure 1) is a portable, battery power ed instrument design ed to pinpoint
the location of either ref r ige rant or c ombustible-gas leak s us ing s ep arate,
interchangeable sensors. The type of gas detected depends on the
sensor installed.
The detector is design ed to be qu ickly responsive, even when high levels
of background vapors or gases are present. No manual sensitivity
adjustments are necessary during the inspection process.
The Informant 2 is suitable for HVAC Service Technicians, Gas Utility
Personnel, Automotive Service Facilities, and Plant Maintenance

2. OPERATION
2.1. Battery Installation
The Informant™ 2
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’ batteries: Energizer E91; Duracell MN1500;
Rayovac 815; and Panasonic AM-3PI.
1. See Figure 2. Using a #1 Phillips screwdriver, first loosen the battery
door screw located at the rear of the detector; then remove the door.
2. Install four ‘AA’ alkaline batteries into the detector, observing the
polarity markings that are molded on the side of the case.
3. Reinstall the battery door and tighten its screw.
Figure 2. Battery Installation
2.2. Sensor Installation Overview
Before leak testing can begin, the appropriate sensor must be installed. If
you have a combustibles-only or refrigerant-only detector, then simply
install the sensor that was supplied with the detector. If, however, you
have a dual detector, then install the sensor that corresponds to the gas
that will be detected during the inspect ion proc es s.
For the detector to maintain agency approval, the blue probe tip must be
used with refrigerant sensor 0019-0510, while the red probe tip must be
used with combustibles sensor 0019-0499.
The color-coded probe tips allow an operator to easily identif y which
sensor is installed — “blue” for refrigerants, and “red” for combustibles.
0019-9211 Rev 9 5
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. See the WARNING below.
2.3. Refrigerant Sensor Installation
Install the refrigerant sensor, filter, and “blue” probe tip onto the end of
the detector’s flexible probe as shown in Figure 3a. Observe the blue
color coding on both the sensor and probe tip.
WARNING: Explosion hazard. DO NOT use the Informant 2 with
its refrigerant sensor installed in an area that is classified by the
National Electrical Code as being a hazardous location where a
potential for explosion or fire exist because of flammable gases or
vapors in the atmosphere.
COMBUSTIBLE REFRIGERANT GAS WARNING: For your
safety, DO NOT use the Informant 2 with the refrigerant sensor to
detect refrigerants which are rated as combustible/flammable
gases (e.g. ASHRAE - A2 or A3 rated refrigerants). Use with
combustible/flammable refrigerant gases can cause an explosion
resulting in death or severe injury.
Figure 3a. Sensor Inst allation (Refrigerant Sensor)
6 0019-9211 Rev 9
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.
The Informant™ 2
NOTE: The Informant 2 is intrinsically safe only when its
combustibles sensor is installed.
Figure 3b. Sensor Installation (Combustibles Sensor)
2.5. Turning the Detector On and Off
See Figure 4. The detector is toggled ON and OFF by pressing the
POWER
button.
When first turned on, observe that the Power LED glows and that all
other LEDs are tested by being turned on for 1 second.
The detector requires 10 seconds to warm up. After which time all LEDs
should be off except for the Power LED, along with the probe tip blinking
and audible indicator ticking at approximately once-per-second.
0019-9211 Rev 9 7
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.
Figure 4. Controls and Indicators
2.6. Low Battery Indication
A low-battery condition is indicated when the
LO BATT
LED glows.
There will be approximately 20 minutes of full operation time remaining
from the time this LED first turns on; after which, the intensity of all LEDs
and audible output will graduall y dim inish.
When a low-battery indication occurs, replace the batteries as described
under the previous Section Battery Installation.
2.7. Audible Indicator Mute
The audible indicator’s ticking sound is toggled on and off by pressing
the
button. Observe that the
MUTE
button’s amber LED glows
MUTE

8 0019-9211 Rev 9
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. All of these indicators show that the detector is currently not
detecting a change in gas concentration.
The Informant™ 2
IMPORTANT: The detector’s function is to detect a change
in gas levels, and not to make a quantitative measurement of
the level. The technique of locating a leak by detecting a
change in level allows an operator to quickly locate the
source of a leak without making manual sensitivity
adjustments, or being concerned about the background
vapor or gas level in the surrounding area.
Leak testing can be performed with the probe either “docked” in its
storage position for close-up leak testing, or unfolded to its maximum
length of 20 inches (508 mm) for locating leaks in hard-to-reach areas.
Begin leak testing by slowly moving the probe toward the area to be
tested. If surfaces are dirty or wet, wipe them off with a clean shop towel
to prevent the filter from clogging. Avoid allowing water to enter the
probe tip.
When the detector first “sees” an increased gas level, all gas-level LEDs
immediately glow along with the probe tip blinking and audible indicator
ticking at a very rapid rate. If movement of the probe is stopped for more
than 10 seconds, the detector’s automatic self-zero feature will cause all
gas-level LEDs to turn off, along with decreasing the blinking and tick ing
rate of the probe tip and audible indicator, respectively.
Once the presence of gas has been determined and the detector allowed
to self zero, moving the probe toward the source of the leak will once
again cause the detector to respond in a positive manner. After which, if
the probe is moved away from the leak source, the detector will respond
with a lower gas-level indication.
0019-9211 Rev 9 9
The Informant™ 2
CAUTION:
When using the refrigerant sensor, note
Use the following general procedure to pinpoint the source of a leak:
1. Move the probe tip along the lines that are carrying gas and around
2. Continue moving in the same direction as long as the detector’s gas-
3. Once the source of the leak has been passed, the detector’s gas
2.9. Sensor Failure Indication
A sensor failure is indicated by the middle gas-level LED on both
displays glowing steady. Refer to the Troub les ho oti ng Guide Section of
this manual for information on how to clear this condition.
2.10. False Refrigerant Indication
False refrigerant indications are usually caused by abnormal changes in
sensor temperature. These temperature changes are typically due to a
sudden change in air flow past the sensor, or the sensor being heated by
an outside source. To avoid false refrigerant indications, DO NOT . . .
10 0019-9211 Rev 9
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.
As for the combustible sensor, exposing it to a high
concentration of combustible gas may temporarily make the
detector less responsive to lower gas levels. If this occurs,
move the detector to an area of fresh air for several minutes
to purge the sensor of gas.
the fittings until the detector responds in a positive manner.
level LEDs remain at full scale. This indicates that the gas
concentration is increasing.
level indicators will all begin to decrease. At this point, reverse the
direction of probing. As the probe tip is moved back and forth across
the leak, the detector will autom atically adjust its sensitivity to allow
the user to pinpoint its source.

•
allow the probe’s filter to become covered with water,
•
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 t he ga s -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. When this condition occurs, move the detector to an
area of fresh air until all indicators return to their idle state.
The Informant™ 2
2.12. SAE Refrigerant Leak Detection Tips
The following was derived from SAE Surface Vehicle Standard J1628,
Technician Procedure for Using Electronic Refrigerant Leak Detectors for
Service of Mobile Air-Conditioning Systems:
• The electronic leak detector shall be operated in accordance with the
equipment manufacturer’s operating instructions.
• Leak test with the engine not in operation.
• The air conditioning system shall be charged with sufficient refrigerant
to have a gauge pressure of at least 340 kPa (49 psi) when not in
operation. At temperatures below 15 °C (59 °F), leaks may not be
measurable, since this pressure may not be reached.
• Take care not to contaminate the detector probe tip if the part being
tested is contaminated. If the part is particularly dirty, it should be
wiped off with a dry shop towel or blown off with shop air. No cleaners
or solvents shall be used, since many electronic detectors are sensitive
to their ingredients.
• Visually trace the entire refrigerant system, and look for signs of air-
conditioning lubricant leakage, damage, and corrosion on all lines,
hoses, and components. Each questionable area shall be carefully
checked with the detector probe, as well as all fittings, hose-to-line
couplings, refrigerant controls, service ports with caps in place, brazed
or welded areas, and areas around attachment points and hold-downs
on lines and components.
0019-9211 Rev 9 11
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.
Slower and closer movement of the probe greatly improves the
likelihood of finding a leak.
• An apparent leak shall be verified at least once by blowing shop air into
the area of the suspected leak, if necessary, and repeating the check
of the area. In cases of very large leaks, blowing out the area with
shop air often helps locate the exact position of the leak.
• Leak testing of the evaporator core while in the air conditioning module
shall be accomplished by turning the air conditioning blower on high for
a period of 15 seconds minimum, shutting it off, then waiting an
additional 15 seconds minimum for the refrigerant to accumulate in the
case, then inserting the leak detector probe into the blower resistor
block or condensate drain hole if no water is present, or into the
closest opening in the heating/ventilation/air conditioning case to the
evaporator, such as the heater duct or a vent duct. If the detector
activates, a leak apparently has been found.
• Following any service to the refrigerant system of the vehicle, and any
other service which disturbs the refrigerant system, a leak test of the
repair and of the service ports of the refrigerant system shall be done.
12 0019-9211 Rev 9
3. MAINTENANCE
3.1. Introduction
The Informant™ 2
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 short en
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).
0019-9211 Rev 9 13
The Informant™ 2
Material Required:
• Probe Filter (refer to Section Replacement Parts)
Procedure:
1. Turn OFF detector.
2. Unscrew probe tip.
3. Remove filter following the appropriate procedure below:
a. Refrigerant Sensor — Remove filter from top of sensor.
b. Combustibles Sensor — Remove filter from probe tip (use a
straightened paper clip to poke out filter).
4. Insert replacement filter.
5. Reinstall probe tip.
3.4. Sensor Replacement
Over time a sensor will become less response to gas as it nears the end
of its useful life. (The combustibles sensor has a life expectancy of
approximately 5 years. The refrigerant sensor’s life expectancy is
approximately 150 hours or 1 year of normal use, but will var y dependin g
on the amount of refrigerant that passes through the sensor.)
Replace the sensor as follows (refer back to Figures 3a and 3b).
Material Required:
• Sensor (refer to Section Replacement Parts)
Procedure:
1. Turn OFF detector.
2. Unscrew probe tip.
3. Pull out sensor from its socket and discard.
4. Plug in new sensor, making sure its tab lines up with notch in sensor
housing.
5. If necessary, install a new filter per Section Probe Filter
