Robinair 16356 Universal A/C Dye Cartridges Instruction Manual

1. Introduction

The Robinair 16356 Universal A/C Dye Cartridges are designed to assist in the detection of leaks within automotive air conditioning systems. This product contains a fluorescent dye that, when introduced into the A/C system, will escape at the point of a leak, becoming visible under ultraviolet (UV) light. Each package contains four 1 oz (30 ml) twist-on cartridges, providing enough dye for up to 20 applications. This dye is OEM approved and SAE certified, ensuring compatibility and reliability.

2. Safety Information

Always prioritize safety when working with automotive systems and chemical products. Failure to follow safety precautions may result in injury or damage.

• Eye Protection: Always wear appropriate eye protection, such as safety glasses or goggles, to prevent contact with the dye.
• Skin Protection: Wear protective gloves to avoid skin contact. In case of contact, wash thoroughly with soap and water.
• Ventilation: Use in a well-ventilated area.
• Flammability: Keep away from open flames, sparks, and hot surfaces.
• Storage: Store cartridges in a cool, dry place, away from direct sunlight and out of reach of children and pets.
• Disposal: Dispose of empty cartridges and any contaminated materials according to local environmental regulations.

3. Package Contents

Verify that all items are present upon opening the package:

• Four (4) Robinair 16356 Universal A/C Dye Cartridges (1 oz / 30 ml each)

4. Setup

These dye cartridges are designed for use with compatible Robinair A/C dye injection kits, such as models 16350, 16380, and 16355. Refer to your specific injection kit's manual for detailed instructions on attaching the dye cartridge.

1. Ensure the A/C system is depressurized before connecting any equipment, following proper A/C service procedures.
2. Select one 1 oz (30 ml) dye cartridge.
3. Remove the cap from the dye cartridge.
4. Carefully twist the dye cartridge onto the appropriate fitting of your Robinair dye injection tool. Ensure a secure, leak-free connection.

5. Operating Instructions

Follow these steps to effectively introduce the dye into the A/C system and detect leaks:

1. Connect Injection Tool: Connect the dye injection tool, with the dye cartridge attached, to the low-side service port of the vehicle's A/C system.
2. Inject Dye: Follow the instructions for your specific dye injection tool to inject the entire contents of the 1 oz (30 ml) dye cartridge into the A/C system. This amount is typically sufficient for one application.
3. Circulate Dye: Start the vehicle engine and turn on the A/C system to its coldest setting with the fan on high. Allow the system to run for at least 15-30 minutes to ensure the dye circulates thoroughly throughout the system. For intermittent leaks, longer circulation times or driving the vehicle may be necessary.
4. Inspect for Leaks: After circulation, turn off the engine. Using a UV leak detection lamp and yellow-tinted glasses (often included with leak detection kits), systematically inspect all A/C components for fluorescent dye traces. Pay close attention to common leak points such as compressor seals, hose connections, condenser, evaporator (check drain tube), and service ports.
5. Clean Up: If any dye has spilled during the injection process, clean it immediately with an appropriate cleaner to prevent false readings during inspection.
6. Apply Service Sticker: Once the dye has been added, apply one of the included service stickers to a visible location under the hood, indicating that dye has been added to the A/C system.

6. Maintenance

Proper handling and storage will ensure the longevity and effectiveness of the dye cartridges.

• Storage: Store unused cartridges in their original packaging in a cool, dry, and dark environment.
• Sealing: Ensure caps are tightly sealed on any partially used or unused cartridges to prevent contamination or evaporation.
• Shelf Life: While dye typically has a long shelf life, refer to any expiration dates on the packaging.

7. Troubleshooting

If you encounter issues during the leak detection process, consider the following:

• Dye Not Visible:
  • Ensure your UV lamp is functioning correctly and has fresh batteries.
  • Confirm you are using yellow-tinted glasses, which enhance dye visibility.
  • Allow more time for the dye to circulate through the A/C system.
  • Inspect in a dark environment for optimal visibility.
• No Leak Found, but Refrigerant Still Low:
  • Some leaks may be very small or intermittent, requiring longer observation periods or re-inspection after several days of vehicle use.
  • Consider other diagnostic methods if the dye does not reveal a leak.
• Dye Injection Difficulty:
  • Verify that the dye cartridge is correctly threaded onto the injection tool.
  • Ensure the A/C system pressure is within the acceptable range for dye injection.
