MAINTENANCE INSTRUCTIONS
MAINTENANCE
In blocks of flats and terraced houses, the maintenance of the unit is taken care
of by a property maintenance company or the user, depending on the contract.
Before starting maintenance activities, stop the machine either at the ON/OFF
switch or by removing the fuse from the fuse panel of the dwelling. The safety
switch also turns the unit off when the door is opened.
FILTERS
Outdoor air is filtered in the unit with two types of filters. A G4 class
coarse filter (A) filters off insects, rough pollen and other dust. An F7
class fine filter (B) filters off invisible dust. Extract air is filtered with a
similar G4 class filter as outside air.
Clean the coarse filters (A) by washing them at least two to four times
a year (and more often if needed). Wash a coarse filter with
+25…30
°
C warm water and washing-up liquid, pressing it smoothly.
Do not handle the filters with force. Filters stand cleaning when it is
done properly. They have to be replaced at least every year or when
needed.
The fine filter (B) is not washable. Clean it at the same time as the
coarse filters, using the brush nozzle of a vacuum cleaner. When
cleaning, be careful no to break filter material. To ensure good supply
air quality, replace the filter when needed, preferably 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.
In connection with the cleaning of the filters, it is also advisable to check
the cleanliness of the heat recovery cells (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 sealings 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.
In addition, check in autumn and spring the position of the summer /
winter damper and the leaving of condensing water from the unit as
well as the position of the post-heating radiator thermostat.
Filter guard
VALLOX 70 COMPACT can be equipped with an
optional
filter guard.
The filter guard indicator lights up at speeds 3 and 4 when the filters
are clean; this is normal and does not call for any maintenance activities.
If the indicator does not light up at speed 4, the pressure in the ventilation
ductwork of the building differs from the factory setting. When needed,
an expert may change the setpoint.
If the filter guard symbol already lights
up at fan speed 1 or 2, the filters need cleaning
. If they are clean, the lighting
up may be caused by a clogged up dense mosquito net installed against
mounting instructions in the external grille or by the closing of the supply
air valves in the rooms.
