CAUTION Never leave the gas analyzer running without the watertrap attached, as sucked in dust or cleaning
agents may irreparably damage the instrument. Ideally, switch off the gas analyzer or go into Standby
mode when cleaning the instrument.
Replace PM Parts
Every 12months the following PM parts should be replaced:
• fan filter
• watertrap manifold seals
Replacing the Fan Filter
1 Pull out the fan filter towards you from the fan and replace it with a new one.
Replacing the Watertrap Manifold Seals
1 Pull out the two seals from the tubing connectors of the manifold using pointed tweezers; slide one
side of the tweezers between the seal and the connector, then grasp and pull.
2 Take a new seal in the tweezers and press it onto the fitting in the tubing connector. Push down on
the seal using the handle of the tweezers (or another blunt instrument), taking care not to damage
the seal, until it sits properly. Repeat with the second seal.
