Maintenance and care
!
Damage to the appliance and envi-
ronment
Maintenance work, such as checking the
electrical safety, must only be carried out by
a qualified contractor.
 Protect the appliance from dust
and dirt ingress during building
work.
» A damp cloth is sufficient for cleaning all
plastic and sheet metal parts. Never use
abrasive or corrosive cleaning agents.
» Every month, check that the condensate
drain is working correctly (visual inspec-
tion). When doing so, check whether water
is collecting below or next to the appliance.

We recommend an annual inspection (to es-
tablish the current condition of the system),
and maintenance by a contractor if required
(to return the system to its original condition).
