- Connect the Collection Bottle: Ensure the liquid collection bottle is securely attached to the unit. Verify all seals are tight to prevent leaks and maintain suction.
- Attach Suction Tubing: Connect one end of the suction tubing to the appropriate port on the collection bottle. The other end will be connected to the suction catheter during operation.
- Connect Power: Plug the power cord into the unit's power inlet, then into a grounded electrical outlet (AC 220V / 50Hz).
- Initial Check: Before first use, turn on the unit briefly to ensure it powers on and the pump operates.
5. Operating the Suction Unit
- Prepare for Suction: Ensure the patient is in a comfortable and appropriate position for suctioning. Have all necessary suction catheters and sterile water/saline ready.
- Power On: Press the power switch to turn on the unit. The indicator light should illuminate.
- Adjust Suction Pressure: Use the pressure regulating knob to set the desired negative pressure. The pressure gauge will display the current setting. Start with a lower pressure and adjust as needed, following medical guidelines. The regulating range is 0.02 MPa to 0.075 MPa.
- Connect Catheter: Connect the appropriate suction catheter to the free end of the suction tubing.
- Perform Suctioning: Insert the catheter as instructed by medical professionals. Apply suction by occluding the control port on the catheter (if applicable) or by using the foot pedal (if equipped).
- Monitor Collection: Observe the liquid collection bottle during suctioning. Do not allow it to overfill.
- Power Off: After suctioning is complete, turn off the unit using the power switch.
Note: Always follow specific medical protocols and physician's orders for suctioning procedures.

7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Unit does not power on. | Power cord not plugged in; power outlet malfunction; unit switch off. | Ensure power cord is securely plugged in. Test outlet with another device. Turn unit switch to ON position. |
| No or low suction. | Collection bottle not sealed; tubing kinked or blocked; filter clogged; pressure knob set too low. | Check bottle seal. Inspect and clear tubing. Replace filter. Adjust pressure knob to a higher setting. |
| Excessive noise during operation. | Unit not on a stable surface; internal component issue. | Place unit on a flat, stable surface. If noise persists, contact customer support. |
| Liquid overflow in bottle. | Bottle not emptied regularly; overflow protection malfunction. | Empty bottle before it reaches maximum capacity. If overflow protection fails, discontinue use and contact support. |
If troubleshooting steps do not resolve the issue, do not attempt to repair the unit yourself. Contact qualified service personnel or the manufacturer.
