Flow measuring device

4.2 Preventive maintenance

The oven design is specifically designed to eliminate the need for extensive and complex maintenance. Where preventive
maintenance procedures require particular time frames or intervals, maintain an inspection log and inspection data. Figure 4.1
lists inspection routines, with recommended time intervals for each routine. In addition, verify analyzer using a validation
sample periodically to ensure operating efficiency.
To aid in preventive maintenance, keep reference chromatograms for comparison and assisting with early
detection of issues as described in the Troubleshooting section.

4.2.1 Gas cylinder replacement

When you use two cylinders to supply a gas, connect the cylinders in an automatic switchover configuration to ensure
continuous flow to the analyzer when replacing an exhausted cylinder. In this configuration, the second cylinder switches in
automatically when the first cylinder is exhausted (100 psig or less). When your inspection indicates an exhausted cylinder,
replace the cylinder with another containing the specified gas.

Perform a visual inspection of the analyzer and sample system.
Check:
• Instrument air supply
• Sample system flows and pressures
Cylinder gas pressures; replace as necessary
•
Verify calibrate and calibrate as necessary.
Compare resultant chromatograms with those in Data Package.
Check/set analytical flows and pressure as necessary per factory data
package.
Backup controller tables after calibration and/or any changes to system
operational parameters.
Check carrier line dryers; change as necessary to prevent pressure drop.
Check all filters; clean or replace as necessary.
Inspect analytical valves for wear and proper operation; replace as
necessary.
Check physical condition of analyzer for corrosion, rust, etc.; take
corrective action as necessary.
