The installation must be performed by a trained installer.
Because a clean, standard-compliant installation to the manufacturer's specifications is indispensable for a flawlessly hygienic ventilation system.
If the system is installed carefully, you can be sure that no dirt will get into it because of issues that arose during the construction phase. The ventilation tubes must remain sealed with caps during the installation phase, for instance, so that no dirt from the building site enters them.
A professional will install the system in such a way that all important system openings remain easily accessible for carrying out maintenance work during subsequent operation.
