Safety

Observe the safety instructions and the technical data. Mounting, adjustment or cleaning is only permitted by specialised installers. Observe the applicable technical standards, EU directives, EU regulations, accident prevention regulations and occupational health and safety measures.

The outside air opening must not be used in the following situations under any circumstances.

• In the case of outside air containing pollutants (e.g. in the case of a burning smell). Danger from exhaust fumes. Close the inner cover by hand, to prevent the pollutants potentially entering the interior rooms.
• In case of incorrect installation position. If sloped towards the interior wall, any condensate produced may run into the interior of the building. This can lead to damage. Observe the correct installation position. Operation is only permitted with correctly fitted covers.

Risk to health if filters are not replaced or if there are no air filters. Very dirty air filters can accumulate harmful substances (mould, germs etc.).

• Only operate the outside air opening with regular air filter changes and never without an air filter.
• Only use original air filters with the prescribed filter class.
• Clean the air filter every 3 months, replace it after one year at the latest. Replace the air filter even after the outside air opening has not been used for long period of time.

Adaptations to structural conditions are permitted as described in these instructions. Other modifications or alterations to the outside air opening are not permitted and release Maico from any guarantee and liability.
