3. Maintenance instructions
3.1. Filters
When the filter guard (option) indicator lights up, check the cleanliness
of the filters. Outdoor air is filtered in the unit with two kinds of filters. A
G3 class coarse filter (A) filters off insects, heavy pollen and other dust.
An F7 class fine filter (B) filters off fine dust invisible to the eye. Extract
air is filtered with a similar G3 class filter as outside air.
T
Clean the coarse filters (A) by e.g. vacuuming them 2 to 4 times a year
and whenever the filter guard indicates a need for maintenance. When
you open the door of Vallox132 E, the security switch (T) turns voltage
off. You can also wash the filters with +25...30 °C warm water and
washing-up liquid, pressing them smoothly. Do not handle the filters with
force. When washing is done properly, filters stand cleaning a few times.
In other words, you have to replace them at least once a year or when
needed.
The fine filter (B) is not washable. Clean it at the same time as the G3
class filters by vacuuming it with a brush nozzle. When cleaning, be
careful not to break filter material. To ensure good supply air quality,
replace the filter when needed, at least at one-year intervals, depending
on local air quality. It is recommended to replace filters in autumn. This
way the filters stay cleaner through the winter and can effectively filter off
dust in the following spring.
When cleaning the filters, it is also advisable to check the cleanliness of the heat recovery
cell (C) every two years or so. Grab the ears at the ends of the cell and pull the cell out
of the unit. If the cell is contaminated, soak it in a solution of water and washing-up liquid.
Rinse the cell clean with a jet of water. When all the water has drained from between the
laminas, push the cell back so that the seals next to the sliding surfaces are in place and
the "up" sticker at the end of the cell points to the corner next to the upper support.
