Operational Guidelines

To ensure optimal performance and longevity, follow these key operational instructions:

• Oil Requirements: Use only oil specifically refined for deep vacuum pumps. The pump ships with trace oil and requires filling to the marked level (250 ml) before operation. Failure to add oil will damage the pump and void the warranty.
• Oil Level Monitoring: Check the oil level via the sight glass after running the pump for two minutes with the intake capped. Add oil if below the marked line.
• Gas Ballast Valve: Open the valve 1/4 turn during the initial evacuation to reduce moisture and extend pump life. Close it after two minutes for maximum vacuum.
• Oil Maintenance: Change oil after every evacuation if contaminated, or if the pump has been idle for over a month. Dispose of used oil according to local regulations.
• Safety Precautions: Wear safety glasses, avoid contact with hot surfaces, and do not operate in the presence of flammable gases. Keep the pump indoors to avoid electrical hazards.
