9.5.1 Recommended maintenance and inspection
Since dust collects when using the unit for several years, performance of the unit
will deteriorate to some extent. As taking apart and cleaning interiors of units
requires technical expertise and in order to ensure the best possible maintenance
of your units, we recommend to enter into a maintenance and inspection contract
on top of normal maintenance activities. Our network of dealers has access to a
permanent stock of essential components in order to keep your unit in operation
as long as possible. Contact your dealer for more information.
When asking your dealer for an intervention, always state:
▪ The complete model name of the unit.
▪ The manufacturing number (stated on the nameplate of the unit).
▪ The installation date.
▪ The symptoms or malfunction, and details of the defect.
