2. Changing air filter
It is required to change air filter with the one produced by us in case of foam or dusts fully ac-
cumulated in the air filter, which leads to gradually darkening of the color of filter diaphragm and
obviously reducing or even disappearing of suction force at the inlet of tube while the negative
pressure indicated on the vacuum meter climbs up to 300 mmHg or more.
Note 1: The suction force will diminish or disappear, and the negative pressure ascend if the
overflow device is closed, and the tube blocked in the process of
application. Please refer to "Trouble Shooting".
Note 2: Necessary to frequently change air filter and destroy it centrally.
3. Changing the fuse tube
The fuse tube is mounted at the rear of the base. Switch off the power supply, and turn it counter-
clockwise and open, then, start changing the tube
4. Maintenance
• It is recommended to have the suction tube suctioned small amount of clean water for cleaning
up the inner wall;
• After use, empty the holder, clean up dirt on the holder and plug with soft brush or rag, flush it
with water and conduct sterilization. (including the overflow device, the seal ring and various
tubes. Unscrew the overflow device, and separate the float from its support for completely clean-
ing up, if necessary. (Note: The rubber valve clack shall not be separated from the float.)
• Use the physiological saline to clean out the residual strong phlegm and mucus in the tube after
used. Replace the suction catheter if not smooth. It is recommended to adopt one-time suction
catheter;
• Place the holder, cover and all tubes into the disinfectant compounded with the Kangweida
disinfector tablets (0.5 g per tablet) in 1:500 concentration for 1 hour
Note: Keep the glass holder away from any sharp utensils to avoid drop in the process of cleaning
and application.
• Wipe the case outer surface with lightly wet rag already soaked in the disinfectant, and prevent
any liquid seeping into the pump. Never wipe the places marked with letters and patterns;
• Place the machine in dry and clean places, and periodically start running once a time (normally
one time every 6 months).
Note: Install the overflow device, conductor and other tubes as per the connecting mode before
re-use.
