Air filter

CAUTION: Never operate the ventilation unit without an air filter → Ventilation unit and pipelines get dirty, unfiltered substances can enter the rooms. Only use original air filters with prescribed filter class → In case of non-compliance, risk to health due to harmful substances that can accumulate in the air filter. Pay attention to the filter change indicator. Change the air filters regularly, after six months at the latest. Replace the air filters even after the ventilation unit has not been used for a longer period of time.

DANGER: Before changing the filter, risk of burns from hot surfaces, e.g. on the heat register. Before the filter change, disconnect the unit at all poles from the power supply (switch off mains fuse), secure against being accidentally switched back on and fit a visible warning sign.
