4.2 Replacing the Ventilator Filter

The CNF 4 ventilation unit has a filter that can be checked and if required cleaned or replaced. The cover of the

ventilator cover (black part in picture below) can be removed by just pulling it down from the CNR 4. The filter

needs to be checked for dust and particles every 6 – 12 months. It can be cleaned by simply washing it in clean

water or it can be replaced by a new one. To remount the cover and filter just click it back on the ventilator.
