• Ensure the pump is connected to a grounded power outlet with the correct voltage (110V/60Hz).
• Do not operate the pump without sufficient oil in the reservoir. Check the oil level before each use.
• Avoid touching hot surfaces during and immediately after operation. The pump can become hot.
• Keep the pump away from moisture and flammable materials.
• Disconnect power before performing any maintenance or repairs.
• Do not use the pump for purposes other than its intended use (HVAC evacuation, wine degassing, etc.).

Setup

1. Add Vacuum Pump Oil: Remove the oil fill cap and pour the provided vacuum pump oil into the reservoir until the level is between the "MIN" and "MAX" marks on the sight glass. Do not overfill.
2. Secure Connections: Ensure all connections to the system being evacuated are tight and leak-free. The pump features 1/4" flare intake ports.
3. Power Connection: Connect the pump to a standard 110V/60Hz electrical outlet.

Operating Instructions

Follow these steps for general operation of the vacuum pump:

1. Verify the oil level is correct before starting.
2. Ensure all valves on the manifold gauge set (if used) are closed.
3. Connect the vacuum pump to the system using appropriate hoses.
4. Turn on the vacuum pump using the ON/OFF switch.
5. Slowly open the manifold gauge set valves to begin evacuation.
6. Monitor the vacuum gauge until the desired vacuum level is reached (e.g., 37.5 microns or 5 Pa).
7. Once the desired vacuum is achieved, close the manifold gauge set valves, then turn off the vacuum pump.
8. Disconnect the hoses from the system.

Maintenance

• Oil Level Check: Regularly check the oil level through the sight glass. Maintain the oil level between the MIN and MAX indicators.
• Oil Change: Change the vacuum pump oil regularly, especially if it appears cloudy or discolored. To change oil, place a suitable container under the oil drain valve, remove the oil drain plug, and allow the old oil to drain completely. Replace the plug and refill with new vacuum pump oil through the oil intake.
• Cleaning: Keep the pump exterior clean and free from dust and debris to ensure proper heat dissipation.
