Operation and maintenance 

NEW EcoHeater 

DSEH200301.01.EN

Continuous product development may give rise to specification changes without notice.

6.4  Damper (code EMT-01)

The purpose of the dampers is to regulate the air flow. Faulty function gives rise 

to disturbances that may result in serious problems.

If the damper does not: 

 open completely, the air flow is  

reduced (leaks) leading to increased energy use.

 Inspection

1.  Check the function of the damper actuator.
2.  Check that damper tightens when closed. If they are not sealed, adjust the 

damper actuator to make the damper tight.

3.  Check the sealing strips.
4.  If the damper is not working, check that there are no screws penetrating the 

drive mechanism/damper blades to interfere with damper function.

 Cleaning

Clean the damper blades with a cloth. In the event of heavy soiling, an 

environmentally friendly degreasing agent can be used.
