If your unit is equipped with an optionnal wall control (C12 / CM or C34 / CMR)
you should perform this maintenance when the Filter Maintenance light stays
ON. Otherwise, this maintenance must be performed once a year to ensure your
unit proper operation for years to come. Proceed as the Biannual Maintenance
(Section 6.1), but instead of replacing the prefilter (point 4), discard the complete
HEPA Filter cartridge (including prefilter). Install a new HEPA filter cartridge (or a
new pleated filter cartridge) with a new prefilter on it.
NOTE: If you are using a washable foam filter, just do the same operations as the
Biannual Maintenance (Section 6.1).

Use the master reset only if you replace the filters before the annual maintenance
indicator is on. By inserting a small rod (eg: paper clip end) during 5 seconds and
more into the reset filter hole of the optional wall control, a master reset will be
done and both biannual and annual maintenance filter are reset.
C12 / CM Control: The filter maintenance indicator will flash 1/4 second.
C34 / CMR Control: If the wall control is in ”Off” position, “Fresh air” light indicator
will flash for 1 second.
If the wall control is in ”Normal” or “Boost” position, the unit
motor, the “Fresh air” light indicator and speed light indicator
(“Normal” or “Boost”) will turn off for 3 seconds.
If the wall control is in ”Recirculation” position, the “Recirculation”
light indicator and the unit motor will turn off during 3 seconds.
