Cleanser for the cell
In order to keep the ventilation unit functioning properly, the heat recovery cell needs to be cleansed regularly. Use only suitable cleaning products, when cleaning the cell. We recommend Likavex- cleanser, which is safe to use for cleansing of ventilations but also other places in the house.
The recommended interval for filter changes is 2–3 times a year. In connection to the filter change, clean the ventilation unit and remove possible loose dirt, for example by using a vacuum cleaner. You should also check the condition of the heat exchanger and clean it if necessary with suitable detergent.
