11 Maintenance 

The measurement quality of the combustion calorimeter can only be ensured if the 
maintenance intervals are adhered to. 
 

 

 

DANGER

 

 

By an improper maintenance can be the device damaged, destroyed or be 
affected in the functioning. Improper maintenance inevitably leads to the loss 
of explosion protection.  

 

Work on the system, must be carried out by trained and authorized staff or by 
the specialists of UNION Instruments service team. 

 

Comply with relevant safety precautions when working in hazardous areas. 

 

The ex-protection function of the enclosure and the flame arresters can only 
be guaranteed can only be ensured in compliance with the maintenance 
intervals. 

 

 

11.1  Preparations 

The feed lines to linked system components can be closed for servicing purposes. 
Once operation has been resumed, they need to be reopened. 
 

 

 

DANGER

 

Serious risk of injury from electricity. 

 

The parts of the combustion calorimeter identified by the adjacent symbol 
may still be live even when the main switch has been turned off. If necessary, 
disconnect combustion calorimeter from the voltage mains!  

 

Turn off main switch, disconnect from power supply if necessary and secure 
against turning on again! 

 

Only a trained electrician may work on the electrical equipment of the 
combustion calorimeter!
