7. Cleaning, maintenance

7.1 Safety instructions

● Disconnect the ventilation unit from the
power before removing the internal cover.
Position a visible warning notice at the fuse
box to avoid the unit being accidentally
switched back on.
● Never operate the ventilation unit without
an air filter. These have to be exchanged
for new ones regularly.

7.2 Changing the air filter

Change the air filter when the filter change
display lights up. Only use original spare
filters (→ Chapter 12).
When operating with room air control
● RLS 4-1,"F" flashes in the display
● RLS 5, "Change air filter" is displayed.
Operating knob, red backlit, flashing.
 Remove the 2 cross-headed screws in the
internal cover and remove the internal cover.
 Take both air filters [1] and [2] out of the
(RLS 5)
ventilation unit. Dispose of these according
to local regulations.
 Clean the inside of the unit and the internal co-
ver with a damp cloth and leave them to dry.
 Insert the new air filter in the ventilation
unit.
 Position the internal cover correctly and fix
it in place with the two cross-headed
screws.
This process causes settings to
be irretrievably lost.
