Maintenance instructions 

DucoBox Energy Comfort

In order to ensure that the ventilation system will operate correctly, the unit must be inspected and maintained at periodic inter-

vals at a number of points. A well-maintained unit has a positive impact on efficiency, runs quieter and boasts a longer service life. 

Please contact your installer in the event of any irregularities.

Always pull the plug out of the power socket or isolate the unit from the power supply before carrying out mainte-

nance or repairs.
