4.4.4 Connecting the CO
2
measuring tube
Requirement • The ventilation hose is connected to the device.
• The measuring circuit connector is connected to the device.
1. Connect the water filter to the CO
2
measuring tube.
2. Connect the CO
2
measuring tube with water filter to the
measuring circuit connector.
Material damage due to lack of a water filter!
If CO
2
is measured without a water filter, the device can suck
in dirt and become damaged.
 Always use a water filter for CO
2
measurement.
The water filter loses efficiency after approx. 8 hours of
continuous operation, depending on the temperature, humidity
and any coarse particles such as mucus. If the effectiveness of the
water filter declines, the device displays the alarm CO
2
occlusion
and issues a medium priority audible alarm. Replace the water
filter after a maximum of 8 hours of continuous operation.
