4. Remove the filter carefully from the filter compartment.
5. Insert the new filter; note that the filter is not forced into the case. Inset the filter covers again such that
the filter slot is also filled uniformly.
6. Proceed in the same way for the upper device filter.
7. Switch on the device again.
2.4.2 Resetting the filter run-time
After the filter change, the counter is to be reset for the filter runtime. For this purpose, the filter message can
again be deleted by pressing the control panel for 5 seconds. The white LED on the control panel shuts off.
2.4.3 What should be done in the case of a failure?
Contact the installer in the case of a failure. Note the type of your ComfoAir 70; for this purpose, refer to the
type plate under the design-cover hood of the device.
The mains connection must always be available, unless the ComfoAir 70 must be put out of operation due to
a serious failure, maintenance work or for other imperative reasons.
As soon as there is a power disconnection, the residence is no longer mechanically
ventilated. There can thereby be damp problems and mould problems in the residence.
Switching off ComfoAir 70 for long is thus to be avoided!
According to DIN 1946-6, the decentralized ventilation device must be in full operation, except
during maintenance and repair works. For the period of absence, the plant should be
operated at the lowest fan speed or in the un-occupied mode!
