7. Instruccions de funcionament
- Comprovació prèvia al funcionament:
- Verify oil level is correct.
- Assegureu-vos que totes les connexions siguin segures.
- Confirm the power supply matches the pump's requirements (220V/50Hz).
- Inici de la bomba:
- Turn the power switch to the "ON" position. The pump should start running smoothly.
- Allow the pump to run for a few minutes to warm up and circulate the oil.
- Evacuation Process:
- Open the valve on the system being evacuated to allow the pump to draw a vacuum.
- Monitor the vacuum gauge (if connected to your system) to observe the evacuation progress.
- The pump will continue to pull a vacuum until the desired level is reached or the system is fully evacuated.
- Aturar la bomba:
- Once evacuation is complete, close the valve on the system to isolate the vacuum.
- Turn the power switch on the pump to the "OFF" position.
- Desconnecteu la mànega de buit de la bomba.
8. Manteniment
El manteniment regular és crucial per a la longevitat i el rendiment òptim de la bomba de buit.
- Canvi d'oli:
- Vacuum pump oil should be changed regularly, typically after every 10-20 hours of operation, or if it appears cloudy or discolored.
- Assegureu-vos que la bomba estigui apagada i freda.
- Place a suitable container under the oil drain plug (usually at the bottom or side of the oil reservoir).
- Remove the drain plug and the oil fill cap to allow the oil to drain completely.
- Replace the drain plug and refill with new, clean vacuum pump oil as described in the "Setup" section.
