to assemble the filter before operating the unit; replace a new filter after max 3 cleaning cycles. In case of soft bag filte r 
(option), replace it when dirty. 
 

Condensation discharge 

 
Remove side panel and clean, if necessary, the dirt and impurities that have formed in the condensation tray. Also check 
the efficiency of the trap. 
 

Water coil 

 
Check that the coil exchanger (optional) is clean and in perfect state to guarantee the normal levels of performance. 
 

Yearly maintenance 

 
Check that all the electrical equipment, in particular the fixing of the electrical connections. 
Check  the  tightness  of  all  nut,  bolts,  flanges  and  hydraulic  connections  that  the  vibrations  of  the  machine  may  have 
loosened.
