7.2. Filter replacement

7.2.1. General

When the filter has been used for 6 months, the control box displays
Replace filter. This is the time for your installation to undergo its annual
maintenance.
Get in touch with us, by using the telephone number shown on your
control box, to obtain a new filter. Please do not use any other type of
filter as this could damage the appliance.
This is the procedure to follow :

7.2.2. Opening the cover

The appliance automatically stops as soon as the cover
is opened.
Hold the cover and unscrew the adjusting knob on the front side to
release the cover, which can then be gently tipped down. It is held by
a hinge.
If there are any deposits take the opportunity to clean inside the cover
and the air inlet duct : unscrew the two locking wing screws and
remove the protection screen.
Advice: Vacuum to eliminate any dirt. Then wipe with a damp cloth to
remove the dust. Dry with a dry cloth.
Remember to replace the screen, as this is useful for ensuring items,
such leaves or other objects do not prematurely block the filter.
Take the opportunity to clean the outside screens and diffusers inside.
7.2.3. Remove the old filter and put in a new one
The filter is held by spring tabs, which can be released by pulling on the
filter, so no dismantling is involved.
Reminder : It is important to use the right filter categories
so as not to damage the unit or cause any incidents.
Insert the new filter until it reaches the bottom of its housing.
Close the cover again.

7.2.4. Calibrating the new filter

Once the appliance has been dealt with, return to the control box :
Answer YES to the question New Filter? displayed on your control box.
The ATU then launches the calibration procedure to optimise its opera-
ting efficiency and it can therefore operate normally once more.
N.B. : Each time you open the cover, the control box asks if the filter has been replaced.
Answer YES only if you have put in a new filter, otherwise you could seriously disrupt
the appliance !
