- Ensure that the sealing strip is flush all the way round at end of fluid distributor and at end of extension. This must not have any holes or tears to prevent incorrect air from infiltrating the wall sleeve.
- Slide extension into wall sleeve with centring ring(s) up to stop of external cover. Ensure that the side with the gasket is facing the external cover and that the centring ring is positioned as far inside as possible. If using a long extension (> 200 mm), use two centring rings
- Slide slide-in module into wall sleeve up to stop of extension (motor connection cables must be at the top). Gasket on fluid distributor must make full contact with the extension.
- Screw down slide-in module with internal cover (4 screws).
- Plug in plug (8-pin) of both fan connection cables directly on circuit board and guide cables into the grooves and/or channels provided for this purpose. With PPB 30 K, ensure that the humidity sensor is exposed.
