Maintenance 

Safety 

 

CAUTION! 

The installation, adjustment, maintenance and any repairs must be carried out by 

qualified  personnel  informed  of  the  risks  related  to  the  operations  of  equipment  supplied 
from high voltage and high temperature.

 

 

CAUTION! 

The power supply is constantly present in the switch for the unit. Risk of electric 

shock.

 

 

CAUTION! 

After  a  power  failure  the  dehumidifier  may  restart  automatically.  Turn  off  the 

main switch and always padlocked supply before performing any maintenance work

. 

 

 

 

PLEASE NOTE!  For any maintenance or repair:  

 

 

Wait 15 minutes after turning off the dryer before opening any service panelin order to 
allow for the cooling of the reactivation coil.

 

 

Electrically disconnect the dehumidifier via the main switch

 

Disconnect the power plug

 

 

The  maintenance  intervals  depend  on  the  environment  which  the  dehumidifier  is  installed  in.  The 
frequency  of  these  intervals  may  differ  from  one  installation  to  another.  Improper  maintenance  can 
result in decreased performance.

 

 

Filters 

The  dehumidifier  is  equipped  with  two  separate  filters,  one  for  the  process  air  and  one  for  the 
reactivation  air.  The  filters  are  placed  on  the  inputs  airflows  of  the  dehumidifier.  Cleaning  or  filter 
replacement intervals will be determined by the amount of dust and air particles where you installed 
the dehumidifier. 
The filters should be checked at least once a month. 
The unit can be equipped with the differential pressure gauges to check the pressure drop through the 
filters. Do not leave the dehumidifier in operation without the filters: the rotor could be ruined. 

Rotor 

The  rotor  doesn’t  need  maintenance.  However  you  may  need  to  clean  it  very  delicately  with 
compressed air. If it is very dirty, the rotor can be washed with water but before you do this, contact 
your  local  distributor  because  it  is  not  a  routine  operation.  Check  once  a  year  the  bearings  and  the 
surface of the rotor.

 

Electric engines 

The  electric  engines  are  equipped  with  ball  bearings.  Maintenance  operations  of  the  bearings  aren’t 
necessary. Check the engine and any noise once a year
