5. Estimated End Time: when the vacuum is stable, it shows the estimated job completion time including holding time.

6. Vacuum Reading Display: Vacuum readings shows when the vacuum of the  system in real-time is below 8000Pa. The waiting time for the vacuum reading is longer for a larger system.
   Note: The vacuum reading varies due to the sensor placement different. The reading  variances is caused by the uneven air flow during the vacuuming process. The farther the air from the pump, the higher the air density is thus the vacuum reading is higher

7. Leakage level: when the vacuum is stable, check the leakage possibility from 0 to
   100 levels. 0 represent uncertain leakage. The larger the number, the greater the
   possibility of the leakage

If temperature exceeds the offline alarm temperature, the temperature alarm icon ” ” will be displayed on the top of the vacuum pump screen, the motor operation will not be affected.

5. After using the vacuum pump

1. Close the valve between the pump and the pumped container.
2. Turn off the power switch on the pump, unplug the power plug, and remove the connecting pipe.
3. Finally, close the air inlet cap to prevent dirt or floating particles from entering the pump cavity.

Care And Maintenance Precautions

1. When the vacuum is started, the air pressure is relatively high and the pump exhaust volume is large, thus oil mist will be overflowing with a large amount of This is a common phenomenon for a rotary vane vacuum pump. When the vacuum drops to a very low level, the pump exhaust volume is small, and there will be no oil mist. Therefore, user should regularly monitor the oil level via the oil window to avoid running out of oil.

2. During operation, storage and transportation, keep the vacuum pump clean to prevent pollutants such as water, mechanical impurities, etc. from entering the pump so as not to affect the service life of the vacuum pump and the normal operation of the

3. The oil in the pump should be drained if it is not used for a long Store the pump in a dry and clean environment.

4. The diameter of the pipe is larger than the inner diameter of the air inlet to avoid affecting the pumping speed.

5. Check the tightness of the pipe connection to prevent Recommend using the vacuum grease on the connection and clamp it with a clamp to ensurethe seal.

6. Do not use the pump to pump out gases which contain high level of oxygen, metal corrosive and explosive In addition, do not pump in any gases that react with pump oil and containing large amount of water vapor.

7. It is recommended to clean the catcher once every half year.

How to replace the vacuum pump oil

1. Run the pump for about 3-5minutes until it is warmed up to runs out the pump oil.

2. When the pump is running, open the air inlet port at the same time to let the oil flow back to the oil tank. The pump must stop when replacing the oil.
   Stop the pump and open the oil drain plug. Then open the catcher to speed up the process of oil exhausting.

3. Tilt the pump body to completely drain the residual oil, and tighten the drain plug.

4. Open the catch device and add the new pump oil.

5. Cover the air inlet cap and start the pump to run-check the oil level after one
   minute. If the oil level is below the lower limit, slowly add the oil until it reaches the normal oil level. Finally, screw on the catcher.

Troubleshooting Guide
