not exist in the case of fire or explosion.
• The detector is not a toy and should be kept out of reach of children.
• The gas detector must not be installed in the following places:
o outside of buildings, near open gas bottle cases;

o in areas where dirt or dust can disturb the gas detector or where it could be accidentally damaged or knocked
down.
• The detector is not suitable for commercial, industrial use, as well as for primary explosion protection.
• Due to the sensitivity of the gas detector a false alarm caused by other gaseous substances, such as e.g.
aerosols, hair sprays, propellants, cigarette smoke, etc., can not be excluded.
• The influence of strong, static, electronic or high-frequency fields, such as discharges, cordless phones, radio

liability for resulting damages.
3. Installation
• Before you start, please enquire directly at your utility provider what type of gas it is and what characteristics it
has. In the case of tank gas systems you should get information whether the gas is lighter or heavier than air and
where the best place is to install the gas detector.
• Do not operate the device via an extension cable or a distributor, since the gas detector might be discontinued
from the mains during reconnection of other devices.
