REMEMBER:
Clean the filters at least twice a year. Define the
maintenance reminder interval to suit your
needs; see the instruction in section 3.3.21.
(The interval is dependent on the purity of out-
door and indoor air).
The fine filter (B) cannot be cleaned with water. Clean it in connection with the cleaning
of the G3 filters, vacuuming it with a brush roll. When cleaning, take care not to break
the filtration 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 the filters in the
autumn. In this way, the filter will stay fresh during the winter and will efficiently filter dust
in the following spring.
It is advisable to check the cleanliness of the heat recovery cell (C) about every two years,
in connection with the cleaning of the filters. Holding the ears at the end of the cell, pull
the cell out of the unit. If the cell is dirty, wash it by sinking it to water containing washingup
liquid. Rinse the cell clean by showering it with water. When water has flown from between
the sheets, push the cell back into the unit, making sure the sealings against the slide surfaces
are in place and that the "this side up" label at the end of the cell points to the corner
against the upper support.
4. MAINTENANCE INSTRUCTIONS
4.1. Filters
When the maintenance reminder or the filter guard light the indicator
lamp, check the cleanliness of the filters. Outdoor air is filtered in the unit
with two kinds of filters. The G3 coarse filter (A) filters insects and coarse
pollen and dust. The F7 fine filter (B) filters fine dust that is not discernible
to the eye. Extract air is filtered with a similar G3 filter as outdoor air.
Clean the coarse filters (A) when needed i.e by washing them 2 to 4 times
a year and whenever the filter guard indicates a need for maintenance.
When you open thedoor of VALLOX DIGIT SE, the safety switch (T) turns
the unit off. Clean the filters with 25…30
°
C water and washing-up liquid,
pressing them lightly. Do not handle the filters with force. When properly
cleaned, the filters stand cleaning 3 to 4 times. This means
they have to be
replaced every two years or when needed.
The filters and the heat recovery cell. Units are
either right- or left-handed. In the right-handed
model (R) outdoor air comes to the unit from
the right side of the center line as in these
instructions. In the L model, outdoor air comes
from the left side of the unit. The filters, summer
/ winter damper and heating radiator are also
on opposite sides as compared to the R model.
4.1.1 Preheating filter
If the system has been equipped with optional preheating for preventing
the heat recovery cell from freezing, it needs to be serviced at least twice
a year. The heater (A) has been installed in the outdoor air duct (B).
Remove the plug (C) and inner part (D) of the heater. After this, you can
pull out the filter (E) and its frame (F). Remove the filter from the frame.
You can vacuum the filter or carefully wash it in water under 40
°
C and
a detergent. If the filter is damaged, replace it with a new one. Only use
original filters in the heater.
USING THE HEATER WITHOUT FILTER IS PROHIBITED
.
Clean the heater of litter and insects at the same time.
