4. Setup Instructions
Follow these steps to set up your LH-85 vacuum pump:
- Unpacking: Carefully remove the pump from its packaging. Inspect for any visible damage during transit.
- Placement: Place the pump on a stable, level surface in a well-ventilated area. Ensure there is adequate space around the pump for air circulation.
- Connections:
- Connect the appropriate vacuum tubing to the pump's inlet port. Ensure all connections are secure and airtight to prevent vacuum leaks.
- If using for pressure applications (on models with this dual function), connect tubing to the outlet port.
- Power Connection: Ensure the power switch is in the 'OFF' position. Connect the power cord to the pump and then to a grounded electrical outlet with the correct voltage.

5. Operating Instructions
To operate the LSLSL LH-85 vacuum pump:
- Power On: Flip the power switch to the 'ON' position. The pump will begin to operate.
- Vacuum/Pressure Adjustment: If your model includes an adjustable valve, slowly turn the valve to achieve the desired vacuum level or pressure. Monitor the integrated gauge for readings.
- Monitoring: Observe the pump's operation and the vacuum/pressure gauge to ensure it is functioning as expected for your application.
- Power Off: When finished, turn the power switch to the 'OFF' position.
- Ventilation: Allow the system to vent to atmospheric pressure before disconnecting any tubing.
6. Maintenance
The LSLSL LH-85 Oilless Diaphragm Vacuum Pump is designed for low maintenance. Regular checks will ensure optimal performance and longevity.
- Cleaning: Keep the exterior of the pump clean and free from dust and chemical spills. Use a soft, damp cloth for cleaning. Do not use abrasive cleaners or solvents.
- Air Vents: Ensure the air vents are clear and unobstructed to prevent overheating.
- Tubing and Connections: Periodically inspect all tubing and connections for wear, cracks, or leaks. Replace damaged components immediately to maintain vacuum integrity.
- Diaphragm Replacement: While designed for durability, the diaphragm may eventually require replacement. Refer to the manufacturer's guidelines or contact support for diaphragm replacement procedures.
- Storage: When not in use for extended periods, store the pump in a clean, dry environment.
7. Troubleshooting
If you encounter issues with your LH-85 vacuum pump, refer to the following troubleshooting guide:
| Problem | Possible Cause | Solution |
|---|---|---|
| Pump does not start | No power supply; Power switch off; Faulty power cord. | Check power connection and outlet; Ensure switch is ON; Replace power cord if damaged. |
| Low vacuum or no vacuum | Leaky connections; Damaged tubing; Clogged inlet filter; Worn diaphragm. | Check and tighten all connections; Replace damaged tubing; Clean or replace inlet filter; Contact support for diaphragm replacement. |
| Excessive noise or vibration | Pump not on a level surface; Internal component issue. | Ensure pump is on a stable, level surface; Contact support if noise persists. |
| Pump overheats | Obstructed air vents; Prolonged operation in high ambient temperature. | Clear air vents; Ensure adequate ventilation; Allow pump to cool down. |
If the problem persists after attempting these solutions, please contact LSLSL customer support for further assistance.
