Operating Instructions and Parts Manual 24510
A/C REFRIGERANT
LEAK DETECTOR
• Always perform vehicle service in a properly
ventilated area. Never run an engine without proper
ventilation for its exhaust. Stop work and take
necessary steps to improve ventilation in the work
area if you develop momentary eye, nose, or throat
irritation as this indicates inadequate ventilation.
• Engine parts that are in motion and unexpected
movement of a vehicle can injure or kill. When
working near moving engine parts, wear snug fit
clothing and keep hands and fingers away from
moving parts. Keep hoses and tools clear of moving
parts. Always stay clear of moving engine parts.
Hoses and tools can be thrown through the air if not
kept clear of moving engine parts. The unexpected
movement of a vehicle can injure or kill. When
working on vehicles always set the parking brake or
block the wheels.
• Be alert for hot engine parts to avoid accidental
burns.
• When under pressure, refrigerants become liquid.
When accidentally released from the liquid state they
evaporate and become gaseous. As they evaporate,
they can freeze tissue very rapidly. When these
gases are breathed in, the lungs can be seriously
damaged. If sufficient quantities are taken into the
lungs, death can result. If you believe you have
exposed your lungs to released refrigerant, seek
immediate medical assistance. Refrigerants can
cause frostbite and severe burns to exposed skin.
Refrigerants are under pressure and can be forcibly
sprayed in all directions if carelessly handled. Avoid
contact with refrigerants and always wear protective
gloves and make certain other exposed skin is
properly covered. Refrigerants can also severely
injure or cause permanent blindness to unprotected
eyes. Avoid contact with refrigerants and always
wear safety goggles.
• Avoid accidental fire and/or explosion. Do not smoke
near engine fuel and battery components.
• The warnings, precautions, and instructions
discussed in this manual cannot cover all possible
conditions and situations that may occur. The
operator must understand that common sense and
caution are factors which cannot be built into this
product, but must be supplied by the operator.
• The manufacturer declines any and all responsibility
for damage to vehicles or components if said
damage is the result of unskillful handling by the
operator or of failure to observe the basic safety
rules set forth in the instruction manual.
DISPOSAL
• At the end of the useful life of the A/C Refrigerant
Leak Detector, dispose of the components according
to all state, federal, and local regulations.
• All technicians opening the refrigeration circuit in
automotive air conditioning systems must now
be certified in refrigerant recovery and recycling
procedures to be in compliance with Section 609
of the Clean Air Act Amendments of 1990. For
information on certification call MACS Worldwide at
(215) 631-7020.
• The 1990 amendments to the United States Clean
Air Act mandate that all personnel who service
refrigerant systems must be trained and certified.
Fines are in place for violations and compliance is
now being monitored by the U.S. EPA.
• Do Not Vent Refrigerant to the Atmosphere. Use
Appropriate Recovery Equipment.

PURPOSE
The purpose of this tool is to allow the user to perform
electronic leak detection of refrigerant gas from A/C
Systems.
APPLICATIONS
The 24510 Leak Detector can also be used in:
- Other systems and storage/recovery containers
- The unit responds to all halogenated (with Chlorine
and Fluorine included) refrigerants. This includes,
but is not limited to: CFCs R12, R11, R500, R503,
HCFCs R22, R123, R124, R502, HFCs R34a, R404a,
R125.
- Detect Ethylene Oxide gas leaks in hospital sterilizing
equipment (it will detect the halogenated carrier gas)
- Detect SF-6 in high voltage circuit breakers.
- Detect most gases that contain Chlorine, Fluorine,
and Bromine (halogen gases)
- Detect cleaning agents used in dry cleaning
applications such as perchloroethyl.
- Detects halogen gases in fire-extinguishing system.
OPERATING INSTRUCTIONS
Read the ENTIRE IMPORTANT INSTRUCTIONS
AND SAFETY RULES section at the beginning of this
document including all text under subheadings therein
before set up or use of this product.
1. To turn the unit on, long press the Power Key,
all LED’s should come on for 3 seconds and
the detector will automatically reset to ambient
conditions. After the auto-reset, only the first
LED will be left on. (Green, Batteries OK, Orange,
Batteries weak and will need to be replaced soon,
Red, Batteries need to be replaced before using)
2. The default sensitivity level is 4. You will hear a
rapid, steady beep sound. The sensitivity can be
adjusted by pressing Sensitivity or Sensitivity
, according to your requirement.
3. Begin searching for leaks. When a leak is detected,
the rate of the beep will increase noticeably and
the Indicator Lights will progressively turn on.
4. Sensitivity can be adjusted at any time using the
or .
5. If a leak is detected before reaching the leak
source, press the Reset Key to reset the Leak
Detector to the ambient conditions, and then try
again.
6. Press the Mute key to stop the beeping sound and
use the lights only for detecting, press it again to
turn the sound on.
DETECTION METHOD
1. Visually examine the refrigeration system. The oily
and dirty spots, valves, coils, connections, fitting
and lines are the area’s most likely to leak.
2. Start leak detecting at a speed of 1cm/second and
a distance of 1-3 cm from the suspected leak area.
3. When an alarm is triggered, it may indicate a leak
is close by. Detect around that area again to see
if the alarm is repeatable. If a leak is confirmed,
pinpoint the leak source by moving slowly from the
non-leaking area and back to the leaking area from
different directions.
4. Additional work may be needed to eliminate
possibility of false detection. Be aware that
contaminants can cause false detection, it may
be necessary to blow clean dry air into the leaking
area and repeat step 3 above.
5. Evaporator Coil Leaks are more difficult to confirm
that other areas because it is difficult to access the
entire surface of the Coil. You can insert the probe
into the vent, condensation drain (making sure not
to let condensate touch the tip) or other access
point to detect the air inside the Evaporator Case.
Most refrigerants are lighter than air and are likely
to accumulate at the highest spot.
NOTES
1. In order to detect leaks, the system must have
normal operating pressure.
2. Leaking areas are usually contaminated with dirt
and oil, be sure to not let the tip come into contact
with these contaminants.
3. In areas with a large leak, it may be necessary to
press the Reset Key to reset the Leak Detector to
the ambient conditions to prevent a continuous
sounding of the alarm.
4. To prevent false alarms, be sure to prevent contact
of the Sensor Tip with any moisture or solvents.
