MAINTENANCE INSTRUCTIONS
Other parts of the ventilation system
Ductwork
In blocks of flats and terraced houses, the housing company takes care
of the maintenance and cleaning of the ductwork in accordance with
the regulations and instructions. In detached houses, the owner takes
care of the cleaning.
Valves
The valves may be gently cleaned on the surface. It is forbidden to
remove the valves and to change their adjustment values. Room dust
may also gather around the supply air filter. The easiest way to remove
it is to vacuum the valve with a brush nozzle. Dirt does not come from
the ductwork with ventilation, but consists of dust in indoor air. This dust
sticks to the ceiling or the wall caused by the flow coming from the
valve.
Cooker hood
(connected to the ventilation unit)
The most important object of maintenance is the grease filter. To
ensure sufficient absorption capacity it needs to be cleaned sufficient-
ly frequently, once or twice a month. The filter can usually be cleaned
in a dishwasher for example. It is also important to keep the whole
cooker hood clean. Neglecting the cleaning of the filter reduces the
abatement of fumes and may cause a risk of fire. For more detailed
maintenance instructions for instance on the changing of lamps, see
the instructions of the cooker hood.
Cooker hood
(with an integrated fan)
Follow the same instructions as for the cooker hood connected to the
ventilation unit. For special instructions, see the instructions of the
cooker hood.
NOTE! It is absolutely forbidden to flambé under the cooker hood.
VALVE OPERATION
Dusty indoor air sticks to
the ceiling drawn by
clean air.
