Checking the fan
Even if the required maintenance, such as changing of filters is carried out, dust and grease may slowly build up inside
the fan. This will reduce the efficiency.
The fan may be cleaned with a cloth or a soft brush. Do not use water. White spirit can be used to remove accumula-
tions which are otherwise difficult to remove. Allow drying properly before use.
The fan can easily be taken out, by removing 4 screws (pos 1) shown in figure 3 and disconnecting the fast couplings
to the electric wires.

Cleaning louvers and diffusers
Check the louvers and diffusers at least twice a year, and clean if necessary.
The system supplies fresh air to the building via the duct system and diffusers/louvers. Diffusers and louvers are
mounted in ceilings/walls.
Remove diffusers and louvers and wash in hot soapy water as required. (Diffusers/louvers must be put back with their
original settings and positions in order not to unbalance the system).
5.4
Checking the outdoor air intake
Leaves and pollution could plug up the air intake grille and reduce the capacity.
Check the air intake grille at least twice a year, and clean if necessary.
5.5
Checking the duct system
Dust and grease settlements may build up in the duct system even if filters are changed regularly. 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).
Note:
In addition the roof cowl must be checked once a year and cleaned as necessary.
