5 Maintenance
Zehnder recommends you to get a maintenance
contract with an expert company. Some installers
provide a maintenance contract in which the user
maintenance can be integrated. Contact the supplier
of the unit for a list of registered installers nearby.
Do not disconnect the power of the unit, unless
told otherwise in the manual of the unit. This
can lead to a build-up of moisture and result in
problems with mould.
Do the maintenance tasks within the given
periods. If not, the performance of the ventilation
system will decrease.
