5. Instrucciones de configuración
- Desembalaje e Inspección: Carefully remove the compressor and all accessories from the packaging. Inspect for any visible damage.
- Llenado de aceite: Before initial use, replace the oil suction device and fill the compressor with the appropriate oil (refer to the oil type specified in the separate oil instructions or product labeling). Ensure the oil level is correct.
- Cooling Water System Setup:
- Place an external bucket of clean water near the compressor.
- Connect the provided water pump to the water hose and submerge the pump in the bucket.
- Connect the other end of the water hose to the compressor's water inlet.
- Ensure the water pump is powered and circulating water through the compressor's cooling system before starting the compressor.
- Filtration System Connection: Connect the blue oil and water filter with its hose to the designated port on the compressor. This two-stage filtration system helps ensure cleaner air output.
- Inflation Nozzle Connection: Attach the 8mm quick connector inflation nozzle to the air outlet of the compressor.
- Conexión de energía: Connect the power cord to the compressor and then to a standard 110V household power outlet.

6. Instrucciones de funcionamiento
- Comprobación previa a la operación: Verify all setup steps are complete, including oil level, cooling water circulation, and secure connections.
- Establezca la presión deseada: Use the adjustable pressure gauge to set the desired shut-off pressure. The compressor will automatically stop when this pressure is reached.
- Conectar dispositivo: Connect the device to be filled (e.g., scuba tank, paintball tank) to the 8mm quick connector inflation nozzle.
- Iniciar compresor: Encienda el interruptor de encendido. El compresor comenzará a funcionar.
- Operación del monitor: Continuously monitor the pressure gauge and the digital thermometer for the cooling system. Ensure the cooling water is circulating effectively and the compressor does not overheat.
- Cierre automático: Once the set pressure is reached, the compressor will automatically shut off.
- Liberar presión: After the compressor stops, slowly open the release valve to vent any residual pressure in the hose before disconnecting the filled device.
- Desconectar dispositivo: Once pressure is released, disconnect the filled device from the inflation nozzle.
- Apagado: Turn off the compressor's power switch and disconnect from the main power supply.
Typical Inflation Times:
- Filling a 0.5-liter water tank from 0-300 bar: Approximately 3 minutes.
- Filling a 6.8-liter water tank from 0-300 bar: Approximately 45 minutes.
7. Mantenimiento
Regular maintenance is crucial for the longevity and safe operation of your compressor.
- Oil Checks and Changes: Regularly check the oil level using the oil level line. Change the compressor oil according to the manufacturer's recommendations or after a specified number of operating hours.
- Reemplazo del filtro: The built-in two-stage water-oil filter and any external filters should be inspected and replaced periodically to ensure optimal air quality. Use the provided replacement filter material.
- Mantenimiento del sistema de enfriamiento: Ensure the cooling water is clean. Periodically clean the water pump and hoses to prevent blockages.
- Draining Water/Oil: After use, especially in humid conditions, drain any accumulated water or oil from the appropriate outlets to prevent corrosion and maintain performance.
- Limpieza general: Mantenga el exterior del compresor limpio y libre de polvo y residuos.
8. Solución de problemas
If you encounter issues with your compressor, consider the following common troubleshooting steps:
- El compresor no arranca: Check power connection, ensure the power switch is on, and verify the circuit breaker has not tripped.
- El compresor funciona pero no genera presión: Check for leaks in connections, ensure the release valve is closed, and verify the inflation nozzle is properly connected to the device.
- El compresor se sobrecalienta: Ensure the cooling water system is functioning correctly, the water pump is circulating water, and the water level in the external bucket is sufficient. Operate in a well-ventilated area.
- El apagado automático no funciona: Verify the pressure setting on the adjustable gauge. If the issue persists, contact customer support.
- Air quality issues (e.g., moisture in air): Replace the water-oil filter elements. Ensure proper draining of water/oil after use.
For persistent issues or problems not covered here, please refer to the support section.
