6. Maintenance and care
!
Appliance and system damage
Maintenance work, such as checking the electrical safety,
must only be carried out by a qualified contractor.
A damp cloth is sufficient for cleaning all plastic and sheet metal
parts. Never use abrasive or corrosive cleaning agents.
We recommend an annual inspection (to establish the current con-
dition of the system), and maintenance by a qualified contractor if
required (to return the system to its original condition).
