To  ensure  continued  full  efficiency  of  the  dehumidifier,  maintenance 
procedures should be performed as follows: 

 

    We  recommend  that  the  filters  are  checked  at  least  once  a  month. 

Intervals  for  cleaning  or  replacement  of  filters  will  depend  on  the 
installation 

    Never  operate  the  dehumidifier  without  the  filters, as  the  rotor  can  be 

damaged by dust. 

To carryout the following, it is necessary to remove the side panels. 

This  machine  should  be  serviced  by  qualified  Ebac  Industrial  Products  Ltd 
personnel  or  other  persons  having  technical  competence  in  servicing 
electrical equipment following the instructions in this Service Manual. 

    The  rotor  is  maintenance  free.  However,  should  it  be  necessary  to 

clean  the  rotor,  compressed  air  should  be  used  to  carefully  blow  dirt 
from the rotor.  

    The heaters are maintenance free. However should it be necessary to 

clean the heaters, compressed air should be used to carefully blow dirt 
from the heaters.  

    Check that the fans are firmly secured and that the fan rotates freely.   

    Check all wiring connections. 

    Check the belt tensioning at regular intervals. 

    The overheat protector is located inside the control panel. To reset this
