Inspection of the suction function
Warning
Use sterile water for inspection of the suction function. Failure to do so may pose a risk of
infection.
Note
Before inspecting the suction function, close the cap of the inlet seal (OF - B190). Failure to do so
may result in a decrease in suction strength.
1. Turn on the suction source and adjust it to a moderate suction setting.
2. Insert the distal end of the endoscope into a container filled with sterile water and press the suction
control valve (OF - B120). Check that water is being suctioned up.

3. Check that when the suction control valve is released, it smoothly returns to the initial position and the
suctioning stops.

4. Repeat steps 2 and 3 several times to check that there is no water leakage from the suction control
valve or the inlet seal.
5. Pull the distal end of the endoscope out of the container. Press the suction control valve, and suction
air in order to remove the water remaining inside the instrument channel.
