VIII. Regular Maintenance

1. Because during operation, the Kjeldahl Distillation Unit will perform the distillation process
that generates heat, a good ventilation and heatsink are required.
2.  Wash  away  the  sediments  in  the  alkali  solution  bottle  and  boric  acid  bottle  and  clear
them up regularly.
3.  Wipe  out  and  clean  the  slot  located  in  front  of  the  instrument,  in  which  the  liquid  may
accumulate.
4. Water scale may accumulate in the distilling bottle after a long time, which can influence
the heating efficiency. Follow the procedures listed below to remove it: Firstly, turn off the
instrument  and  disconnect  the  power  cord;  secondly,  screw  the  plug  out  from  the  distilling
bottle and insert a small funnel in; thirdly, pour in the scale remover or glacial acetic acid to
remove the scale; After the cleaning is done, open the discharge valve located behind the
instrument to discharge the waste water completely and rinse the instrument repeatedly with
the distilled water.
