Filter replacement procedure
 Before starting the filter replacement procedure make sure the unit is in Filter replace-
ment mode. You can activate it only via unit display by selecting and confirming the
appropriate option
01 Press the decorative
cover downwards with both
hands until it reaches its
lower end position and
check the message on the
display. Follow the instruc-
tions on the screen.
02 Pull the corresponding
filter stopper out of the unit
body as shown in the picture
above. Pull out the old filter
by its strap and insert a new
one. Mind the correct posi-
tion of the insertion accord-
ing to the instructions on the
filter. Return the stopper as
far to the back as it fits.
03 Confirm the comple-
tion of the replacement
procedure on the display
keyboard as instructed. The
unit will resume its opera-
tion.
04 Use both hands to
push the decorative cover
upwards. The cover will au-
tomatically move into its up-
per end position.
Cleaning the air diffusers
Air diffusers optimise the direction and flow of intake and exhaust air. For better air permea-
bility, it is required to provide periodic cleaning of both interior and exterior air diffusers at
least once per 6 months. To do so wipe the edges and insides of the diffusers and remove any
sediment dirt with a dry cloth. Avoid using water and chemicals unless absolutely necessary.
Problem solving
In case of an error contact WAFE customer service immediately at +420 273 139 700 .
For easier problem identification, note the error code number (displayed on the unit display)
and the type of your unit (see the nameplate on the side of the unit).
While the unit is not operating due to the error, your home is left without ventilation. This
results in the reduction of indoor air quality and can lead to increased humidity or moulding.
Avoid prolonged shutdowns of your ventilation system.
 During shorter periods of absence, it is appropriate to leave the unit in Intelligent
mode . During longer breaks leave the unit in Holiday mode [Out].
