DANGER
Adiabatic compression (explosion hazard)!
In case of adiabatic compression, high gas temperatures may occur. The operator is re-
sponsible to consider this situation.
Make sure to obey the allowed technical specifications and ambient conditions (see data
sheet), take special attention to the media temperature with respect to temperature
class T3 or T4. These vary in addition to gas composition and ambient conditions. Where
necessary, the operator must install temperature sensors for monitoring and must auto-
matically shut down the sample gas pump should the temperature exceed the limits.
CAUTION
Tilting risk
Damage of the device
Secure the device against any sudden translocation during maintenance.
DANGER
DANGER - Explosion danger in case of high temperatures
Temperature of the device depends on the medium temperature. Correlation between
medium temperature and
temperature classes
is given in the data sheets.
Observe maximum temperature classes T3 or T4 for the pumps and the allowed ambient
temperatures and medium temperatures.
CAUTION
Hot surface
Burning hazard
According to the product type and operation conditions, the temperature of the housing
may exceed 50 °C during operation.
Depending on the conditions at the installation site it may be necessary to provide these
areas with appropriate warning signs.
