1. Introducció
This manual provides essential instructions for the safe and effective operation and maintenance of your ATD-3410 Air Operated Vacuum Pump. This tool is designed for automotive air conditioning systems, compatible with R-134a and R-12 refrigerants. It operates using compressed shop air to create a vacuum, which is crucial for evacuating moisture and non-condensable gases from A/C systems before recharging.
Please read this manual thoroughly before using the product to ensure proper function and to prevent damage or injury.
2. Informació de seguretat
Always observe the following safety precautions when operating the ATD-3410 Air Operated Vacuum Pump:
- Protecció ocular: Always wear ANSI-approved safety goggles or a face shield when operating or servicing the vacuum pump.
- Protecció auditiva: Use hearing protection in noisy environments, especially when operating air compressors.
- Protecció respiratòria: Avoid inhaling refrigerant vapors. Work in a well-ventilated area or use appropriate respiratory protection.
- Seguretat de l'aire comprimit: Ensure your air compressor is properly maintained and equipped with a pressure regulator. Never exceed the maximum recommended air pressure for the vacuum pump.
- Manipulació de refrigerants: Handle refrigerants with care. Refer to local regulations and safety data sheets (SDS) for specific handling procedures. Avoid skin contact with liquid refrigerant, as it can cause frostbite.
- Pressió del sistema: Ensure the A/C system is depressurized before connecting the vacuum pump.
- Condició de l'eina: Inspect the vacuum pump and all hoses for damage before each use. Do not use damaged equipment.
- Ventilació: Operate the vacuum pump in a well-ventilated area to dissipate any refrigerant vapors.

4. Configuració
Proper setup is crucial for the efficient operation of the vacuum pump.
- Requisits del compressor d'aire: Ensure your air compressor is rated for at least 4.2 CFM (Cubic Feet per Minute) at 90 PSI (Pounds per Square Inch). The pump requires a minimum of 75 PSI and a maximum of 180 PSI for optimal performance. A larger compressor with a high volume tank is recommended to maintain consistent airflow.
- Connecteu el subministrament d'aire: Connect your shop air line to the "Air In" port on the vacuum pump. This port is typically a brass fitting.
- Connect to A/C System: Connect a service hose from your A/C manifold gauge set to the "Vacuum" port on the front of the vacuum pump. Ensure all connections are tight to prevent air leaks.

5. Instruccions de funcionament
Follow these steps to evacuate an automotive A/C system:
- Prepare A/C System: Ensure the A/C system is completely depressurized and any remaining refrigerant has been recovered according to environmental regulations.
- Connect Manifold Gauges: Connect your A/C manifold gauge set to the high and low-pressure service ports of the vehicle's A/C system.
- Connect Vacuum Pump: Connect the center service hose from your manifold gauge set to the vacuum pump's "Vacuum" port.
- Vàlvules obertes: Open both the high and low-side valves on your manifold gauge set.
- Activate Air Supply: Turn on the air compressor and ensure it is supplying air to the vacuum pump within the specified pressure range (75-180 PSI). The vacuum pump will begin to operate, drawing a vacuum on the A/C system.
- Monitor de buit: Observe the vacuum gauge on your manifold set. The pump is capable of pulling a vacuum of up to 28.3 inches of Mercury (inHg) at sea level with 90 PSI air supply. Allow the pump to run until the desired vacuum level is reached and held for a specified period (typically 30-60 minutes, or as recommended by the vehicle manufacturer).
- Isolate System: Once the desired vacuum is achieved, close the high and low-side valves on your manifold gauge set. Then, turn off the air supply to the vacuum pump.
- Comproveu si hi ha fuites: Monitor the vacuum gauge for at least 15-30 minutes. If the vacuum level drops, it indicates a leak in the A/C system or connections. Identify and repair any leaks before proceeding.
- Desconnectar: After confirming the system holds vacuum, disconnect the vacuum pump and manifold gauge set from the vehicle. The system is now ready for recharging.
6. Manteniment
The ATD-3410 Air Operated Vacuum Pump is designed for minimal maintenance due to its air-operated nature. It does not require oil or specific lubrication.
- Neteja: Keep the exterior of the pump clean and free from dirt and debris. Use a damp drap per netejar.
- Emmagatzematge: Store the vacuum pump in a clean, dry environment when not in use.
- Inspecció: Periodically inspect the air inlet and vacuum ports for any obstructions or damage. Ensure all fittings are secure.
