At the conclusion of a test series, it is highly recommended to “purge” the console plumbing by drawing
in clean, ambient air for 10 minutes or greater. This process will extend the life of the internal tubing,
fittings and dry gas meter. The purge can be conducted by turning the sample pump (internal or
external for certain options) on and opening the valves to draw air through the inlet of the sample port
on the front of the console when it is not connected to other equipment or a sample train.
Maintaining the cleanliness of the console will also extend the life of its components. The outside of the
case and console can be cleaned with a non-abrasive, weak degreaser or soapy water. Ensure that
exposed electrical components are not sprayed during this process.
Never clean the console while it is connected to power or powered on.
Periodically inspect components of the console to ensure everything is in working order and nothing is
exhibiting a sign of future issues. Check for things such as exposed or frayed wires, melted or
damaged electrical components, discolored or cloudy tubing, and any sign of oil or moisture. The
console can be safely vacuumed out while disconnected from power in a dry location. Vacuuming the
internals of the console will remove any dust or particulate buildup that could cause issues in the long
term. Any signs of damage to the internal or external components of the console should be replaced
immediately.

4.3.2 Cleaning
4.3.3 Inspections
All components of the console should be audited and evaluated on a semi-annual schedule (once a
quarter or every six months). This comprehensive procedure should include audits of the dry gas meter
thermocouples and electrical components. Post-test calibrations and audits satisfy this suggestion.
Apex Instruments highly recommends that the console be returned to Apex Instruments on an annual
basis. The Technical Services Group will perform an evaluation of all components of the system
including functionality and build-integrity checks. All sensors and the dry gas meter can also be
calibrated at this time.
