10.5 Cleaning the CL500
Flush the system as mentioned in section 10.1 Maintenance Schedule. When the flushing
is finished, press the SEVICE button wait until the display reads HOLd.
As a mater of safety, always disconnect any power source to the CL500 prior to
attempting any cleaning. It is recommended that the source water is also shut off.
Isopropyl alcohol (rubbing alcohol) on a soft cotton cloth works very well in removing
reagent stains from plastic parts, the key pad and the display. Use care when cleaning
around electrical components. Do not use any harsh cleaning agents as these may cause
damage to the instrument components.
Ensure that the system is dry prior to applying power.
