Replacing the air filter

  1. Change the air filter when the filter change indicator appears. Only use original air filters. If other filters are used, the ventilation system may be damaged. This will render the guarantee null and void!
  2. De-energise the unit.
  3. Open the cover for servicing filters. Pull the two filters out of the ventilation unit. Dispose of them according to local regulations.
  5. Slide the new filters into the ventilation unit. Note air direction.

Only use the reinforced corners to slide the filter into the ventilation unit with the dust air side on the left (see label printed on the filter). To avoid damage to the filter, make sure you do not press it in the middle.

  1. Close the cover by working in reverse order.
  2. On the control panel, reset the timer for the filter change interval to zero. The filter runtime is reset on the RLS 1 WR control panel by pressing the two buttons at the same time (5 sec). The LED for ventilation level 2 stops flashing.
