Thermo Fisher Scientific
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.
σ
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.
Use the following leak test procedure to verify that there are no system leaks.
1. Set the sample and air regulators for zero pressure.
2. Replace the tubing from the EXHAUST bulkhead on the left side of the
instrument with a plug.
3. Adjust the auxiliary air regulator for 20 psig pressure.
4. Turn the auxiliary air regulator fully counterclockwise to close the supply
flow.
5. Watch the analyzer pressure for 15 minutes.
6. If the pressure drops significantly, perform the following to locate the
leak:
a. Adjust the sample and air regulators for 20 psig pressure.
b. Check the system fittings with a liquid or electronic leak detector.
c. Correct any leakage.
d. Repeat the leak test.
7. When the system passes the leak test, adjust the sample and air regulators
fully counterclockwise to close supply flows.
