QUICK GUIDE
CO2 Guard 10
Enclosure, Mounting
Putting into Operation
The CO2 Guard 10 shows the carbon dioxide (CO
2
) concentration in the ambient air as the measure for the indoor air
quality (IAQ) and can indicate the need for ventilation for instance by opening the windows. Air exchange based on the
actual CO
2
concentration can significantly reduce energy costs.
Opening the enclosure:
Press latch A gently until front cover can be
opened.
Closing the enclosure:
Set front cover into flute B and move it to direction
C until latch A snaps in.
Wall mount:
Fix the back cover onto the wall using the screws
in the scope of supply and the D holes. See
packaging for drill pattern.
Ideal height above the floor 1.20…1.50 m (4…5 ft)
Scope of Supply
Insert the batteries observing the right polarity. This may require some pressure. To make safe contact with the terminals of
the battery holder, the batteries may need to be slightly moved or rotated. Close the enclosure (see above).
The CO2 Guard 10 shall be placed far from the windows and min. 1.50 m (5 ft) from people.
When employing rechargeable batteries, it is obligatory to remove the rechargeable batteries from the CO2 Guard 10 and use
an appropriate battery charger (not in the scope of supply).
This device is not appropriate for safety, emergency stop or other critical applications where device malfunction or failure
could cause injury or damage to human health.
For disposal, the individual components of the device must be separated according to local recycling regulations. Especially
the batteries shall be disposed of correctly.
Battery Replacement
All LEDs flashing together indicate weak batteries. For replacement use alkaline batteries type AAA 1.5 V or rechargeable
batteries of type AAA 1.2 V only. Open/close the device as described above.
The LEDs show the actual CO
2
range in a traffic light style which indicates an IAQ rating as shown in the table:
LED flashes
1)
CO
2
range [ppm]
2)
Indoor air quality (IAQ)
Red 2 Higher than 3000 Very bad
Red 1 2000...3000 Bad
Yellow 2 1400...2000 Acceptable
Yellow 1 1000...1400 Average
Green 2 800...1000 Good
Green 1 Lower than 800 Very good
1) All LEDs flashing together: Weak batteries
Red 2 continuously on: Error
2) Note: The outdoor CO
2
concentration is approx. 400 ppm

Tabletop adapter:
Assemble according to sketch
and place the device on it.
The device beeps decently as soon
as the next lower air quality level
(the next higher CO
2
range) is reached.
