Maintenance of the ventilator means regular cleaning of the ventilator surfaces of dust and cleaning and replacement of the filters. To
enable access to the main units, follow the procedure described below. The ventilator must be previously turned off using the remote
control or the buttons on the indoor unit. Then turn off power supply completely.
