Maintenance 

Agilent Sample Introduction Pump System SIPS 10/20 User’s Guide 

71 

Switch off the mains power to the control module on the rear of the 
instrument. Check that the control module is firmly seated in the 
ventilation slots on the rear of the instrument. Check that the 
connecting cable from the power module to the SIPS pump module is 
secured. If not, disconnect and refit. When complete, switch the 
power back on again. 

Touch up any scratches on the epoxy painted surfaces. Use a cotton 
bud (Q Tip) or small brush to apply a small amount of color matched 
automotive touch-up paint to seal the scratch and prevent corrosion
