Recommendations for 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 air conditioner
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 air conditioner.
• The manufacturing number (stated on the
nameplate of the unit).
• The installation date.
• The symptoms or malfunction, and details of the
defect.
