4.3 DECOMMISSIONING 

 

 

All work on the dryer may only be carried out by specialist personnel! 
Follow this procedure if you need to shut down the dryer: 
 

 

Stop the device and permanently isolate it from the electricity mains; 

 

Disconnect the power cable; 

 

Take pressure off the air circuit; 

 

Empty the tank and the internal cooling medium circuits; 

 

If the device has to be dispatched, use the original or similar packaging and keep the device in an up-right position. 

 
Before carrying out any work on the electrical parts, make sure that the main switch interrupts the electricity supply to the 
dryer  and then affix appropriate warning signs to avoid the machine being reconnected to the electricity mains! 
 
Please consult the contents and the safety instructions in the relevant sections of these instructions for details of the correct 
handling  and  storage  of  the  drer.  Remove  any  residual  cooling  medium  from  the  dryer  in  a  manner  appropriate  to  its 
properties and in accordance with the legislation in force. 
 
If the device has to be demolished: Never open the sealed cooling assembly (compressor, evaporator and condenser) if 
there may be any refrigerant or lubricating oil present! 
 
Send the dryer to an approved waste disposal company in accordance with current environmental protection legislation. The 
other materials/waste constituents must be treated in line with the provisions of the valid legislation.
