Maintenance by the operator
Maintenance of the ventilation device and plant by the operator is limited to the periodic change of the filters and
cleaning of the supply and extract air valves. The filter must be checked every 3 months and changed if necessary,
however, at least every 6 months.
In this context, also check other filters available inside the ventilation plant and change them if necessary. A
replacement or cleaning of the filter mats at the extract air valves (e.g. bathroom, kitchen, W.C.s) should be carried
out every 2 – 3 months or at your own discretion when checking the degree of soiling.
If maintenance work is not carried out regularly, this impairs the functioning of the comfort
ventilation in the long term!
Replacement of the filter
The plant must not be operated without filter. During filter replacement and maintenance work, the
ventilation device must be switched off!
Two high-quality original filters of the manufacturer are installed inside the CLIMOS. After the corresponding
message of the control panel or after visualisation of a programmed digital output signal, the filters in the CLIMOS
shall be checked. In order to do so, proceed as follows:
1. Switch the device to standby mode or disconnect it from the power supply.
2. If applicable, pull the red design filter cover

out of the casing cover’s holder.
3. Grasp into the recessed grip

of the filter compartment.
Perhaps the EPP-filter covers are very tight during the first filter change. Using a blunt
object (e.g., the handle of a spoon) the EPP-filter cover can be levered.
