3. Package Contents

The package contains:

• 1 x Vintage Air #8-90DEG A/C Hose End (Model 35532-VUG)

4. Installation (Setup)

Installation of A/C system components requires specialized knowledge and tools. Professional installation by a certified automotive technician is highly recommended to ensure proper function and safety.

Safety Precautions:

• Always disconnect the vehicle's battery before beginning any work on the A/C system.
• Wear appropriate personal protective equipment, including eye protection and gloves.
• Refrigerant is under high pressure and can cause injury. Ensure the A/C system is properly discharged by a professional before disconnecting any lines.

General Installation Steps:

1. Prepare Hose: Cut the A/C hose to the required length, ensuring clean, square cuts.
2. Attach Crimp End: Insert the hose into the crimp-style end of the #8-90DEG fitting. Use a specialized crimping tool to securely attach the fitting to the hose according to the crimp tool manufacturer's instructions. Proper crimping is critical for a leak-free seal.
3. Connect Threaded End: Thread the hexagonal nut onto the corresponding A/C component (e.g., compressor, condenser, evaporator). Hand-tighten first, then use an appropriate wrench to tighten to the manufacturer's specified torque. Do not overtighten.
4. System Evacuation and Recharge: After all connections are made, the A/C system must be evacuated to remove air and moisture, then recharged with the correct type and amount of refrigerant. This process requires specialized equipment and should be performed by a qualified technician.
5. Leak Test: Perform a thorough leak test using an appropriate leak detection method to ensure all connections are sealed.

5. Operation

Once correctly installed, the Vintage Air #8-90DEG A/C Hose End functions as a permanent, sealed connection within your vehicle's air conditioning system. It facilitates the flow of refrigerant and maintains system integrity. No user interaction is required for its operation beyond initial installation.

6. Maintenance

Regular maintenance for this component involves periodic inspection of the A/C system for any signs of leaks or damage around the hose end connections. Ensure all connections remain secure. If any leaks are detected, professional service is recommended immediately to prevent further system damage or refrigerant loss.

7. Troubleshooting

If the A/C system is not functioning correctly after installation, or if refrigerant leaks are observed, consider the following:

• Check Connections: Verify that the threaded connection is tightened to the manufacturer's specifications and that the crimped connection is properly sealed. Improper crimping is a common cause of leaks.
• Inspect for Damage: Look for any visible damage to the hose end, the connected hose, or surrounding components that could compromise the seal.
• Professional Diagnosis: If issues persist, or if you are unsure about the cause of a problem, consult a qualified automotive A/C technician for diagnosis and repair. Attempting repairs without proper knowledge and tools can lead to further damage or injury.
