Specified Use 

Specified Use 

The SCC-S sample gas feed unit is designed for continuous dosed sample gas 
feeding. 

The SCC-S sample gas feed unit with Peltier cooler is additionally designed for 
cooling the sample gas and separating and removing the condensate. 

Any other application is not compliant with the specified use. 

Observation of this operator's manual is also part of the specified use. 

The SCC-S sample gas feed unit must not be used 

For feeding mixtures of gas/air or gas/oxygen that are capable of ignition

during normal service,

For feeding flammable gas which may form an explosive mixture with air or

oxygen, and

In a potentially explosive atmosphere or in hazardous areas.
