4. Cleaning extract louvers and inlet diffusers
The system supplies fresh air to your home and extracts the used indoor air via the duct system and
diffusers/louvers. Diffusers and louvers are mounted in ceilings/walls in bedrooms, living room,
wetrooms, WC etc. Remove diffusers and louvers and wash in hot soapy water as required (Fig.6).
(Diffusers/ louvers must not be exchanged).

5. Checking the fresh air intake (at least twice a year)
Leaves and pollution could plug up the air intake grille (Fig.7) and reduce the capacity. Check the air
intake grille, and clean as necessary.

6. Checking the duct system (every 5 years)
Dust and grease settlements may, even if required maintenance such as changing of filters is being
carried out, build up in the duct system. 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/ louver openings or special inspection
hatches in the duct system (if fitted) (Fig.8).

NOTE! In addition roof cowl must be checked once a year and cleaned as necessary.
