MAINTENANCE AND REPAIRS
Heat exchanger
The secondary air drawn in is filtered before flowing through the heat exchanger, so no significant soiling should occur if
the filter is changed regularly. Clean the heat exchanger carefully with a brush if it does become soiled. Ensure that the
aluminium fins are not bent out of shape during cleaning!
Fan
The fan is maintenance-free. If you nonetheless detect any soiling of the fan impeller surface during the visual inspection,
you can wipe it with a damp cloth. The fan must be replaced in the event of damage.

Replacement and repairs may only be performed
by authorised personnel. We recommend that
you contact our customer service department
before replacing individual defective or damaged
components.
If any damage is detected on the housing or other
supporting components, the defective unit must be
replaced completely.
The unit must be isolated from the power supply
across all poles for this purpose.
