Changing G4 and F7 unit filters

If Level 3/Nominal ventilation flashes on the operating unit (only when the status display is activated), a filter change is due. Additionally, the LED lights up white on the operating unit.

Recommendation: Change all unit filters at the same time.

1

Housing cover

1.1

Screws for housing cover (10x)

2

Fastening tab, can be bent out

G4

Air filter for outside air (AUL) / exhaust air (ABL)

F7

Fine dust filter for outside air (optional)

Note the supplementary sheet Safety instructions before opening the unit.

  1. APA/UPA/UPGA units: Remove front cover (design/glass).
  2. Remove the filter cover(s).
  3. Pull the unit filter out of the ventilation unit.
  4. Carefully slide new filter into filter shaft. Do not press filter in (cellulose). Only press in at reinforced corners. Make sure that the air direction arrow is facing downwards.
  5. APA/UPA/UPGA units: Insert the design or glass cover at the bottom into the guide of the AP metal shell sheet or UP shell tray and engage it at the top with the locking lever. Ensure that the cover is also correctly engaged. If necessary, turn the locking lever as far as it will go.
  6. Acknowledge the filter change on the RLS G1 WS operating unit. To do so, press the and buttons at the same time for 3 seconds (flashing stops). Also confirm a premature filter change. If resetting prematurely, press the and buttons at the same time for 10 seconds. The LED flashes briefly.
    Alternatively, reset the filter change interval in the AIR@home app/ the AIR@home web tool.
  7. Dispose of the air filter according to local regulations.
