• If you have reason to assume that safe operation is no longer possible, disconnect the prod-
uct immediately and secure it against accidental operation. A safe operation can no longer be
assumed, if:
- the product shows visible signs of damage,
- the product ceases to function
- the product was stored for a longer period of time in unfavourable conditions
- it was exposed to heavy loads during transport.
• In commercial institutions, the accident prevention regulations of the Employer’s Liability
Insurance Association for Electrical Systems and Operating Materials are to be observed.
• Carbon dioxide (CO
2
) is a transparent and odourless gas. Pay attention to your own safety
during all measurements. To protect the life of humans and animals, this device must not be
used in areas where high concentrations of carbon dioxide are used industrially.
If in doubt about how to connect the device correctly, or should any questions arise that are not answered
in these operating instructions, please contact us or another specialist.

INSTALLATION
Place the ambient air indicator so that suf
fi
cient ambient air can
fl
ow through it. The air
fl
ow for measure-
ment enters the device at the back. Avoid narrow spaces, such as between books, etc., in order to prevent
any effects on the measured results. Choose a place where a mains socket is available close by.
With the hanging eyes (1) on the back, the device can easily be hung on two screws, nails, or wall hooks
(distance between eyes: 160 mm). Hanging on two thin steel cables is also conceivable.
Because of the heavy weight, make sure the mounting is stable!

AMBIENT AIR INDICATOR CO-500
Item no. 10 13 01
INTENDED USE
The ambient air indicator “CO-500” is a stationary measuring device for determining the concentration of
carbon dioxide (CO
2
) in the ambient air with NDIR measuring methods (non-dispersive infrared absorption
measurement) that are more exact and more stable over time.
The meter is intended for monitoring the carbon dioxide level in the room air in order to take appropriate
early measures for ventilation. An increased CO
2
level leads to fatigue, lack of concentration and loss of
ef
fi
ciency and performance.
The quality level is displayed by means of a traf
fi
c light indicator (green/yellow/red). The air temperature
and humidity are measured at the same time. All three values are indicated on the display at the same
time.
The device operates on a power supply (included).
Any use other than that described above could lead to damage to this product and involves the risk of short
circuits,
fi
re, electric shock, etc. The safety instructions and all other information must be followed at all
times!
This product complies with the applicable national and European regulations.
