Chapter 8: Maintenance & Troubleshooting
Caution Some internal components can be damaged by small amounts of static
electricity. Take appropriate precautions (use a properly grounded antistatic
wrist strap) when handling electronic boards and components.
To avoid damaging internal components, follow these precautions when
performing any service procedure:
Wear an antistatic wrist strap that is properly connected to earth ground. If an
antistatic wrist strap is not available, be sure to touch a grounded metal object
before touching any internal components.
Handle all printed circuit boards by the edges.
Carefully observe the instructions in each procedure. ▲

Frequency Tasks
Monthly Calibrate the analyzer (see Calibration).
Every three months Replace the injection valve rotors according to
Every six months Visually inspect and clean the instrument.
Check the instrument flow rates as explained later in this chapter.
Replace the valve body according to
Annually Test the instrument for internal leaks as explained later in this chapter.
Every 18 months Replace the pyrolyzer heater as explained later in this chapter.
The analyzer should be inspected occasionally for obvious visible defects, such
as loose connectors, loose fittings, cracked or clogged Teflon lines, and excessive
dust or dirt accumulation. Dust and dirt can accumulate in the instrument and
can cause overheating or component failure. Dirt on the components prevents
efficient heat dissipation and may provide conducting paths for electricity.
Warning Remove all instrument power before cleaning electronics. ▲
The best way to clean the inside of the instrument is to first carefully vacuum
all accessible areas and then blow away the remaining dust with low-pressure
compressed air. Use a soft paintbrush or cloth to remove stubborn dirt.
