Troubleshooting, Cleaning
Cleaning
· Dusty detectors have to be cleaned.
Dust deposits in the air inlets of the detector can be vacuumed or blown out.
· If necessary, you can remove the dust with a brush.
· The surface can be cleaned using a cloth lightly moistened with soapy water.
· Do not allow water to enter the inside of the device!
· Do not clean the device in a dishwasher!
· Do not use sharp, pointed, abrasive, or corrosive cleaning materials or hard
brushes!
· Do not use chemicals and do not clean the detector with highly flammable
liquids!
5. Manual calibration
→ Fresh and dry outdoor air is required for manual calibration when the CO
2
value is approx. 500 ppm. Do not calibrate the detector in the rain.
High humidity increases the CO
2
content in the air. When calibrating
manually, keep the detector away from areas where there are many people
or objects that
could emit CO
2
, such as ventilation pipes, chimneys or cars.
To calibrate manually, place the detector outdoors and press the three
buttons
simultaneously. "CO2" will flash during calibration,
which lasts approx. 16 minutes until the flashing stops. Calibration is
completely automatic.
