• Disconnect the analyzer unit from the gas preparation system.
• Blow out the gas lines with compressed air or clear them mechanically.
• Change the filter elements and packings.
• Check gas line seal integrity.
• Disconnect the analyzer unit from the gas preparation system.
• Check the analyzer unit gas lines for crimping or loose connections.
• Check the integrity of the analyzer unit gas paths (see page 44 for instructions).
• The outlet pressure should be equal to atmospheric pressure.
• Exhaust gases should be routed to the atmosphere or to an exhaust pipe
directly or via the shortest possible large-diameter line.
• Do not route exhaust gases via flow reducers or shutoff valves.
• Take measures to reduce vibration.
• Increase the time constant (see page 28).
• Check the integrity of the analyzer unit gas paths (see page 44 for instructions).
• Check sample component drift reading (status messages 5 and 6, see page 46).
• Have the emitter and modulator assembly checked by the service department.
