Maintenance and care
To keep the unit into specifications, preventive maintenance has to be carried out, with
specific intervals to avoid breakdown, inefficient operation and to maximize the expected
lifetime, of 10 years or more.
It is important to notice, that intervals between filter maintenance can vary depending on the
specific environment. Moving parts are wearing parts, that needs replacements when worn
down, dependent on the specific environment.
The factory warranty is only valid if documented preventive maintenance has been carried
out. The documentation could be in form of a written log.

Check or replace filters when the filter alarm sounds, and flashes on the remote control. Al-

information.
Filter intervals can be adjusted to adapt pollution level in the house, and outdoor air particle
content. See how in "User interaction" on page 27
Filters must, however, be checked every six months. Dantherm always recommends replac-
ing filters at least once a year. When checking the filters, clean the unit externally around the
filter openings with a damp cloth, to maintain good hygiene.
