Setup

Follow these steps to prepare the oil injector for use:

1. Ensure the A/C system is depressurized or properly evacuated before connecting the injector.
2. Unscrew the top cap of the injector barrel.
3. Fill the injector barrel with the required amount of POE oil (up to 1/2 ounce).
4. Re-attach the top cap securely, ensuring a tight seal.
5. Connect the low-side R-1234yf service coupler to the vehicle's low-side A/C service port. Ensure a secure connection.

Operating Instructions

To inject POE oil into the A/C system:

1. With the injector connected to the low-side service port, ensure the vehicle's A/C system is running and the compressor is engaged.
2. Slowly depress the plunger to inject the POE oil into the A/C system. Inject gradually to allow the oil to be drawn into the system.
3. Once the desired amount of oil has been injected, fully retract the plunger.
4. Close the valve on the service coupler (if applicable) and disconnect the injector from the vehicle's A/C system.
5. Replace the service port cap on the vehicle.

Maintenance

Proper maintenance ensures the longevity and performance of your injector:

• After each use, clean the injector thoroughly to prevent contamination.
• Disassemble the injector and clean all components with an appropriate A/C system cleaner.
• Inspect O-rings and seals for wear or damage. Replace if necessary to ensure a leak-free operation.
• Store the injector in a clean, dry place away from direct sunlight and extreme temperatures.

Troubleshooting

Refer to the following for common issues:

• Issue: Oil not injecting smoothly.
  Solution: Check for blockages in the injector or hose. Ensure the A/C system is operating and creating sufficient vacuum/pressure differential to draw in the oil.
• Issue: Leaks at connections.
  Solution: Verify all connections are tight. Inspect O-rings and seals for damage and replace if needed.
