Generally A ventilation unit from Nilan can last for many years if it is properly serviced and maintained. Ventilation units are often hidden away, and they are therefore rarely given attention in everyday life. But just as you maintain your car, your ventilation unit will need servic- ing regularly to keep it functioning properly.

Annual maintenance General cleaning The ventilation unit should be cleaned on the inside once a year. Dust may escape through the filters and potentially mix with moisture from the extract air. WARNING Stop the ventilation unit on the control panel and switch off the power supply for the ventilation unit before you open the front door to the unit.
Heat exchanger The counterflow heat exchanger is a central part of the ventilation unit. It heats up the cold outdoor air with energy from the warm ex- tract air. To maintain a high level of heat recovery, it is important that the heat exchanger is not clogged with dirt. Experience indicates that it should not be necessary to lift out and clean the heat exchanger every year.
