Consult the maintenance recommendations in the manufacturer usage instructions
regarding the periodicity for replacing the filter unit. The ventilator should not venti -
late when the air filter is not in optimal conditions.
It is also recommended to take the following cautions in order to ensure the proper
working of the filter:
• Always keep the device in an upright position.
• If necessary, use a hose connected to the drain outlet in order to collect the con -
densation water in a bowl. Take care that the hose dimensions are correct. An
excessive length may increase the drain resistance unnecessarily.
• If a water-catcher hose is used, check to see that this does not stretch in an
upward direction, as this may hinder the drainage.
The fuse box is found near the main power source input. Located in the rear panel
are two F 2L 250V fuses (Ø 5 mm x 20 mm - 250 V / 2 A). In the case of their repla-
cement being necessary, use fuses of the same characteristics.

The scheduled maintenance is performed every 5000 hours of usage, or every
year, whichever comes first. This is a procedure performed in the factory or by an
authorized service technician.
When the computer is sent out for maintenance, include a note explaining the aty-
pical events which may have occurred. Thus, the assessments will also take these
peculiarities into consideration.
When the 5000 hours of usage are met, the necessity to perform this maintenance
is alerted by an icon, which will appear on the upper right-hand side of the screen.
This icon will be deleted by the service technician once the maintenance protocol
has finished, and will appear again after another 5000 hrs of usage, or after one
year has elapsed since the last service.
The following list summarizes the verification of parts, accessories and consuma -
bles which are executed during a scheduled maintenance of the equipment.
