Preventative maintenance
Preventative maintenance is necessary at regular intervals if the unit has to function ecient-
ly and if you want to ensure the expected lifetime of minimum 10 years.
Check the uid level every week and top up as needed (see detailed procedure in section
“Check the uid level” on page 7).
The air inlet lter of the room unit and the inside of the heat exchanger must be kept clean
in order to ensure best performance. Check once a month and clean as needed. Follow this
procedure to perform the monthly service:
