Duct system maintenance

6.8.1

Cleaning extract louvres and supply air diffusers

The system supplies fresh air to your home and extracts the used indoor air via the duct system and diffusers/louvres.
Diffusers and louvres are mounted in ceilings/walls in bedrooms, living room, wet rooms, WC etc. Remove diffusers
and louvres and wash in hot soapy water as required (diffusers/louvres must not be exchanged). Cleaning of diffusers/
louvres can be done as necessary.
6.8.2

Checking the outdoor air intake

Leaves and pollution could plug up the air intake grille and reduce the capacity. Check the air intake grille, and clean as
necessary. It is recommended to do this at least twice a year.
6.8.3

Checking the roof cowl (if fitted)

The roof cowl (if fitted) connected to the exhaust air duct needs to be checked at least twice a year and cleaned if
necessary.
6.8.4

Checking and cleaning the duct system

Dust and grease deposits may build up in the duct system, even if required maintenance such as changing of filters is
being carried out. This will reduce the efficiency of the installation.
The duct runs should therefore be cleaned/changed when necessary. Steel ducts can be cleaned by pulling a brush
soaked in hot soapy water through the duct via diffuser/louvre openings or special inspection hatches in the duct sys-
tem (if fitted).
It is recommended to do this every 5 years and is normally carried out by authorized companies specialized in this area.
