SPECIFICATIONS:

• Material: Steel
• Compatibility: Designed for use with Tracerline 8 oz (237 ml) BigEZ™ dye cartridges.
• Included in Product when purchased: TP9749 EZ-Shot™ caulking gun-style dye injector assembly. (Note: Hoses, couplers, adapters, and dye cartridges are typically sold separately or as part of complete kits like the TP9790-BX).

HOW TO USE:

1. Prepare the Injector: Unscrew the cap from the Tracerline EZ-Shot TP9749 injector assembly.
2. Load Dye Cartridge: Insert a compatible 8 oz (237 ml) Tracerline BigEZ™ dye cartridge into the injector body, ensuring it is seated correctly.
3. Attach Hose (If applicable): If not already assembled, attach the appropriate A/C system hose and coupler (e.g., R-134a or R-1234yf) to the injector.
4. Connect to A/C System: Connect the hose/coupler to the vehicle’s low-side service port of the A/C system. Ensure a secure connection.
5. Inject Dye: Squeeze the trigger of the injector handle to dispense the fluorescent dye into the A/C system. Continue until the recommended amount of dye has been injected for the system’s capacity.
6. Disconnect and Cap: Once dye injection is complete, disconnect the hose/coupler from the A/C service port and replace any protective caps on the injector and service port.
7. Run System: Allow the A/C system to run for a period (as specified by dye instructions, usually 5–20 minutes) to allow the dye to circulate and mix with the refrigerant.
8. Inspect for Leaks: Use a UV leak detection lamp to scan the A/C components for glowing fluorescent dye, indicating leak points.
