MAINTENANCE INSTRUCTIONS

13

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 no to break filter material.

To ensure good supply air quality, replace the filter preferably every year, and at least every two years
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 cell (C) every two years or so. In this case the lower door must also
be removed. Pull the cell out of the unit by first removing the clamping screws from the
upper weather strip of the cell. 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.

4. Maintenance 

instructions

4.1. Filters

When the maintenance reminder or filter guard turns on the indicator lamp
in the control panel, 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. A F7 class fine filter (B)
filters off fine, invisible dust. Extract air is filtered with similar G3 class
filters as outside air. Clean the coarse filters (A) by washing them at least
twice a year and whenever the filter guard indicates a need for maintenance.
When you open the upper door of VALLOX 180, the security switch (T)
turns voltage off.
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 3 to 4 times. In other words, 

you

have to replace them at least every two years or when needed.

4.2. Fans

Check the cleanliness of the fans in connection with the maintenance of the filters
and heat recovery cells. If needed, clean them. Before cleaning remove the fans from
the unit.

Removing of fans in AC model (alternating current fans)

In order to remove the fans, first remove the heat recovery cell. Remove the supply
air fan from its fixing plate by opening the four clamping screws. After that remove
the electrical connector of the fan cable, the clip plate of the electrical connector
and the clip plate of the fan. Remove the fan from the unit through the space
normally occupied by the heat recovery cell.
Remove the extract air fan from its fixing plate by opening the four clamping
screws. After that, remove the electrical connector of the fan cable. Remove the
fan from the unit through the space normally occupied by the heat recovery cell.

Removing of fans in DC model (direct current fans)

Remove the fans from their fixing plate by opening their mounting nuts. After that,
remove the electrical connectors of the fan cables. Remove the fans from the unit.

Clean the fan blades with compressed air or with brush. Each blade has to be so
clean that the fans stay balanced. Do not remove the balancing pieces attached to
the fan blades.

If you use water in cleaning the unit or its parts, do not let it flow to the electrical parts.

REMEMBER!

Clean the filters at least twice a year. Set the
maintenance reminder interval according to
your needs. See the instructions in 3.3.18.
(dependent on the cleanliness of outdoor and
indoor air).

VALLOX 180 filters and heat recovery cell. The
