Maintenance

It  is  recommended  to  have  the  suction  tube  suctioned  small  amount  of 
clean water for cleaning up the inner wall before switching off the aspirator.
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 cleaning 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 KONVIDA disinfector tablets (0.5 g per tablet) in 1:500 concentration for 
1 hour
Note:  Keep  the  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.

Note: The dismantling & repair on the pump body if fault shall be conducted 
by the specialized worker. Please contact the manufacturer if required.

1)Repair or change the socket
2)Replace the indicator

outlet

1)Empty the 
holder timely

1)After shut-off, turn the 
regulating valve loose 
counterclockwise to release 
negative pressure in tube, 
then re-screw
2)Dredge, clean or replace the 
tube
3)Replace it with air filter 
produced by us.
