17.2.5 Maintenance and Cleaning
„ The sampling line of the sidestream CO
2
module is disposable and cannot be
disinfected for reuse.
„
In case of an exception in the sampling system of the CO
2
module, check for
entanglement of the sampling line. If the sampling line is not entangled, remove
it from the water trap. In this situation, if the screen displays a prompt
information indicating the CO
2
sampling line is abnormal, the water trap must
have been blocked, and you must replace it with a new one. If no prompt
information is given, the sampling line must have been blocked, and you should
replace with a new sampling line.
„ Routine calibration of the sidestream CO
2
module is not required. But the
calibration must be performed every year, or when great inaccuracy of
measurement is found.
