Tracer EZ-JECT, MiniEZ M-L AM11035 (Was A04027-2) - Manual

EZ-Ject™ Multi-Dose and Mini-EZ™ A/C Dye Injection Systems
U.S. Patent Nos. 6,056,162 and 6,050,310
Fluoro-Lite/P ® (for R-134a/PAG systems) and Fluoro-Lite/E ® (universal for R-12 and
R-134a systems) dyes meet or exceed SAE standard J2297 for the stability and
compatibility of UV-fluorescent dyes for refrigerant leak detection in R-134a/PAG
A/C systems.
CAUTION
Since the use of a fluorescent leak detection dye requires the addition of a chemical
substance into the A/C system which may or may not be compatible with the system,
such dyes should not be used unless they are either expressly endorsed by the A/C
system and/or vehicle manufacturer or meet the requirements of SAE J2297.
DYE INJECTION CAUTIONS
• Do not operate the A/C system while the EZ-Ject or Mini-EZ dye injector is
being connected or used.
• Do not connect the EZ-Ject dye injector to a system that is evacuated.
• The system must contain enough refrigerant to operate the compressor and
circulate the dye in order to find leaks.
• Wear protective glasses or goggles while using the EZ-Ject or Mini-EZ dye
injector and working on any vehicle system.
IMPORTANT
The EZ-Ject and Mini-EZ dye cartridges contain dye that fluoresces under ultraviolet
or UV/blue light when mixed with A/C lubricant. For best inspection results, use a high-
intensity Tracerline
® leak detection lamp and wear fluorescence-enhancing glasses to
protect your eyes and to make leaks clearly visible.
EZ-Ject and Mini-EZ hose assemblies must be purged and fully charged with dye
before they are used.
1. Completely unscrew the handle on the injector and screw the cartridge into it.
2. Holding the cartridge vertically with the small cap on top, remove the cap and screw
the cartridge firmly to the check valve on the hose assembly.
3. Insert the adapter/purge fitting into the quick coupler on the hose.
4. Turn the handle to advance the plunger until a small amount of dye exits the
assembly. Remove the adapter/purge fitting. The hose assembly is now purged,
ready for use and will remain full of dye. NOTE: If the dye charge is lost, repeat
steps 3 and 4.
5. a. R-134a SYSTEMS—Connect the R-134a quick coupler at the end of the hose
assembly to the appropriate service port on the vehicle.
b. R-12 SYSTEMS—
• When using the TP-9870 EZ-Ject or TP-9875 Mini-EZ universal dye cartridges,
screw the adapter/purge fitting to the low side service port on the vehicle and
connect the quick coupler attached to the hose assembly.
• When using the TP-9850 EZ-Ject mineral oil cartridge, connect the TP-9846
R-12 hose assembly to the low side access fitting on the vehicle.
6. Turn the plunger to inject the dye. See "Dye Dose" below.
7. Disconnect the hose assembly from the service port and wipe both clean.
8. Start the engine and run the A/C system on maximum for 5 to 10 minutes to
circulate the dye.
9. Turn the engine OFF. Inspect possible leak areas with the lamp. Leaks will glow a
bright yellow-green in R-12/mineral oil systems or green in the R-134a/ester and
R-134a/PAG systems. The fluorescence will be brightest under low light conditions.
10. To find smaller leaks, operate the A/C system over the next 24 to 48 hours and
reinspect.
DYE DOSE
Each EZ-Ject dye cartridge can dose 7 full-size vehicles or up to 14 compact vehicles.
Use the amount of A/C system lubricant, if known, to determine dye dose.
Each 0.25 oz Mini-EZ dye cartridge can dose one full-size vehicle
Do not mix dyes. Always use the dye cartridge with its designated hose
assembly. The hose assembly can be stored containing dye.
• Use TP-9850 EZ-Ject cartridge for R-12/mineral oil systems
• Use TP-9860 EZ-Ject or TP-9865 Mini-EZ dye cartridges for R-134a/PAG systems
• TP-9870 EZ-Ject or TP-9875 Mini-EZ universal dye cartridges are compatible with all
refrigerants and lubricants
CLEANUP/REINSPECTION
After the leaks are repaired, clean the remaining dye from the leak sites with a cloth and
a shop cleaner. Check with the lamp to be sure all dye residue is removed. Residual
dye could give a false leak indication. Run the A/C system another 5 to 10 minutes and
reinspect with the lamp. No glow means that all leaks have been repaired.
