Only specialists are allowed to carry out the work specified below on the ventilation unit. Any defects detected
during servicing must be remedied immediately to ensure safe operation of the unit. Only original spare parts may
be used for repairs and replacements.
17. Maintenance and cleaning
Further installation and system components must be maintained and cleaned in compliance with specifications and instructions. Be
acutely aware of hazards and safety when opening the sealing plate or potential covers. If possible, use a vacuum cleaner to remove
dirt and dust. Applying force or using compressed air for cleaning may damage the components and surfaces. Never use aggressive
or solvent-containing cleaning agents. The electrical components must not be exposed to moisture or wet conditions. The safety
information in Section 5 and in particular the item on electrical connections must be observed when performing any electrical work.
17.3. Cleaning the enthalpy exchanger
Annual cleaning
is recommended at the least, depending on the degree of soiling of the enthalpy exchanger. When maintenance
work is performed, the enthalpy exchanger must be carefully removed from the unit. Cleaning is carried out by rinsing with warm
water (maximum temperature 50 °C). By no means blow through the enthalpy exchanger using compressed air. This might damage
the device!
This requires removing the design front and furthermore opening and removing the sealing plate on the screws at the side.
