Maintenance and care

Preventive maintenance is necessary at regular intervals if the unit is to operate efficiently
and optimally without unintended stoppages, and to ensure the expected service life of at
least 10 years.
It is important to notice that intervals between filter maintenance can vary according to the
specific environment, and that moving parts are wearing parts, and will need replacement
when worn.
The factory warranty only applies if it can be documented that regular preventive main-
tenance has been carried out as prescribed. The documentation can be a written logbook
containing a company stamp or equivalent.
The purpose with the filters is to remove dust and other impurities from the outside air before
it is supplied into the house, and to protect both the heat exchanger and the fans from any
dirt and impurities coming from the house.
As a standard the unit is delivered with G4 filters on both the supply air and the extract air
sides. It is possible to buy F7-pollen filters (accessories) for the supply air, which strains even
more, especially suited for people with pollen allergy.
The filters must be changed at regular intervals, more information regarding change of filters
in the section "Preventive maintenance", on page 14.
The filters are the only parts that the user can maintain himself.
Maintenance of the filter must as a minimum be carried out as shown here:

Other components must be inspected at least every second year by trained professionals (see
page 39). Remember to contact a trained professional for a service check regularly.
The unit has a built-in timer for its filter alarm (every six months as standard). The timer period
for the filter alarm can be changed via the remote control or PC Tool, or it can be reset via the
alarm button
When the timer expires, a filter alarm is triggered. A buzzer will sound and the LED "!" will light
up orange. (if the LED lights up red, please see Troubleshooting section on page 52.
