Changing unit filters

Change the unit filters when the filter change indicator is on.

A pending filter change is displayed on a main control unit (if the status display is switched on under basic settings). On the RLS 1 WR control unit, the LED of ventilation level II flashes regularly at longer intervals.

Recommendation: Change the unit filters together.

  1. Take filter covers out of the ventilation unit. CAUTION: Risk of injury from falling filters. When working at height, observe applicable accident prevention requirements.
  2. Pull the air filter/pollen filter out of the ventilation unit.
  3. Carefully slide the new filters into the filter shaft. NOTICE: Do not press the filters in (cellulose). Only press in at reinforced corners. Make sure that the air direction arrow is facing downwards.
  4. Close filter openings with the filter covers. Ensure correct installation.
  5. Reset filter change interval. To do this, click on the message on the RLS T2 WS screen and confirm the filter change with changed. Also confirm a premature filter change with "changed". For systems with a single RLS 1 WR, press the two arrow keys on the control unit together for 2 seconds. The 3 LEDs flash briefly. If resetting prematurely, press the keys at the same time for 10 seconds.
  6. Dispose of used filters in accordance with local regulations.
