Cleaning, care, maintenance

WARNING: Before cleaning tasks and maintenance tasks, disconnect fan at all poles from the power supply, secure it against being accidentally switched back on and position a visible warning sign.
Cleaning is carried out as required. Cleaning intervals are to be determined by the operating company – frequency depends on ambient conditions and expected impairments.
Maintenance: The fan is maintenance-free. Nevertheless, check the fan from time to time for bearing noises, damage and disproportionate vibrations. In the event of a fault, contact an authorised specialist installer.

CAUTION: Specialist knowledge is needed for proper cleaning and maintenance of the fan. Have the fan cleaned and serviced every two years, by a specialist installer, so that the fan operates hygienically.
