Maintaining the System 
CAUTION 
 
Maintain the system strictly as instructed by this manual. Inappropriate 
maintenance may lead to unreliable results, or even equipment damage 
and personal injury. 
To wipe off dust from the system surface, use a soft, clean and wet (not 
too wet) cloth, soaked with mild soap solution if necessary, to clean the 
surface. Do not use such organic solvents as ethanol for cleaning. After 
cleaning, wipe the surface with dry cloth. 
Switch off all the powers and unplug the power cord before cleaning. 
Take necessary measures to prevent water ingression into the system, 
otherwise it may lead to equipment damage or personal injury. 
Replacement of such major parts as lamp assembly must be followed 
by a calibration. 
Check the pump tubing for leakage as needed and replace the tubing in 
time. Otherwise, the normal aspiration of the system might be affected. 
It is recommended that the inner system tubing should be replaced 
every 24 months to avoid possible blockage or invalidation brought 
about by aging.
