Maintenance by the user
For the user, maintenance of the ventilation unit and system is limited to changing the filters periodically and cleaning
the supply and extract air valves. The filters should be inspected every three months. Filter replacement should be
carried out as necessary, but no later than once every six months. As part of this process, please inspect the other
filters in the ventilation system and change them if necessary. The filter mats should be replaced or cleaned on the
extract air valves (e.g. bathroom, kitchen, WC) every 2–3 months or when checking the degree of contamination at
one's own discretion.
If the maintenance work is not carried out regularly, this will affect the functionality of the comfort
ventilation system in the long run!
Replacing the unit filters
The system must not be operated without filters. During filter replacement and maintenance work, the
ventilation unit must remain switched off!
Two high-quality original filters from the manufacturer are installed in the FOCUS unit. The filters inside the FOCUS
unit must be inspected whenever the control panel signals that this is necessary. In doing so, proceed as follows:
1. Disconnect the unit from the mains power supply.
2. Press the two snap fasteners

on the bottom of the unit.
