Accessories and consumables 

The following parts are available as accessories and consumables for CTR A: 

 

 

Fault tracing 

Fault symptom 

Probable cause 

Actions 

Premises not 

dehumidified/low 

capacity.  

 

 

 

 

 

 

 

 

 

 

 

 

Depending on the situation, 

the cause of the problem 

could be incorrect 

installation, e.g. because of 

obstructed wet air hose, 

clogged filter, incorrect 

settings on the machine or 

machine fault. 

 

 

 

 

 

 

Perform fault tracing as follows until the 

problem has been identified: 

 

Check the installation - check that the wet 

air hose is not obstructed, that the dry air 

damper is in the correct position and that 

the hose used on the dry air side is not 

trapped or clogged. Ensure that the air flow 

is correct. 

If the air flow is weak, check the process air 

filter and replace if necessary.  

 

 

 

The drier does not 

start. 

The drier is set to Hyg. 

without the hygrostat 

connected. 

 

Connect a hygrostat, or switch to Man. 

mode. 

 

 

 

The rotor rotates 

anti-clockwise (seen 

through the dry air 

outlet) or not at all. 

Fault with rotor motor or 

motor capacitor. 

Contact the dealer for repair.  

 

 

 

No air flow, low air 

flow  

Fault with fan or fan 

capacitor.
