Checking the condensate drain 

 

·

 

Open the unit door. 

·

 

Remove the 
condens hose and 
make sure the hose 
is not blocked. Even 
make sure that the 
hose connection to 
the unit not is clogged.  

·

 

If the drain is clogged, try to remove the 
obstruction.If need be, call a plumber. 

·

 

Reconnect the hose. 

·

 

Close the unit door. 

 

 

Cleaning the air diffusers 

 

The building's air diffusers must be 
cleaned regularly in order to maintain 
correct ventilation.  Use a dry cloth 
and/or a small brush to reach inside the 
opening of the diffuser.  It can also be 
taken down if that makes cleaning 
easier.  Use a duster or a dry cloth to 
remove possible dirt marks in the ceiling 
around the device.   
NOTE!  The air diffuser's setting must not be 
changed.  If taken down, each diffuser must be 
returned to its original place. 
 
 

 

Cleaning the duct system

 

 

The exhaust air 
ducts - and 
sometimes the 
supply air ducts as 
well - may need 
cleaning at long 
intervals. Dust and 
dirt will deteriorate 
the capacity of the 
AHU if not removed. 
 
 

 
 
Authorized ventilation cleaners should carry out the 
cleaning.  However, you yourself can easily clean 
the part of the duct which is close to the air 
diffusers. 
Take down the diffuser.  Use a vacuum cleaner or 
duster to clean the inner part of the duct as far as 
you can reach.  Refit the diffuser, making sure the 
setting is not changed.

 

 
 

Checking the outdoor air intake 

 

Once a year the outdoor air intake should be 
checked.  Make sure it is not clogged by for 
example leaves, snow or ice.

 

 
 
Service 

 

Service and repairs, beyond normal maintenance, 
should be carried out by professionals in the 
ventilation field, or - if electricity is involved - by an 
authorized electrician. 
 

 
    The electric panel must not be opened by 
other than authorized specialist. 
 
    Interferance with

 

the AHU system

 

 may affect 

the warranty terms. 
  

    

Use original spare parts only. 

 
 

Disposal 

 

Prevent accidents when the AHU is disposed of.  
Remove the cable from the wall socket and cut it as 
close to the unit as possible.  Store and transport 
the waste unit lying down.   
Please leave the unit to be recycled where such 
facilities exist. Check with your local authority for 
recycling advice.
