4. Use

4.1 Ventilation positions

The system can be switched into the following positions using either the three-
position switch (if fitted) in the kitchen or the non-powered extractor hood:
Position 1 low
In this position, the air supply and exhaust fan is set at minimum. This
position can be activated during long-term absence and possibly at night.
Position 2 medium
In this position, the air supply and exhaust fan is set at a normal rate of
revolutions.
Position 3 high
In this position, the air supply and exhaust fan is set at a high rate of
revolutions. Select this position when cooking or showering.
Do not fit a powered extractor hood to this system
The plug should always remain in the socket unless the unit has to
be deactivated due to a serious malfunction or another matter of
urgency. If the plug is removed, mechanical ventilation of the home
will cease and moisture or mould problems may occur in time.
Therefore, you should avoid switching the unit off for longer periods.
Contact your installer in the case of any malfunction. If a malfunction code
can be seen on the display, please contact the installer.

5. User maintenance

5.1 General

Maintenance by the user is limited to periodic cleaning of the filters and
air intake and exhaust valves and replacing the filters annually. Twice a
year, the display on the operating panel will show alternating texts "Fil"
followed by "tER" as a reminder that the filters must be cleaned. It is
recommended that all valves be cleaned at the same time as the filters.
The installation must not be used without filters.
Check the free flow of the condensation drain in and outside the
unit, and the siphon, once a year.
