Fig. 6 Remove/mount the inner front
The inner front is mounted with four screws. Loosen the screws and pull the
inner front towards you.
Mount the inner front and tighten the mounting screws properly to prevent
air leakage.
Note:
When mounting the inner front, note the two guide screws at the
bottom of the inner front. These screws shall be fitted into the
two slots in the inner hatch support bracket.
5.4 To change filters
The filters cannot be cleaned and must be changed as necessary. This is nor-
mally done 1–2 times per year depending on the air pollution at the installa-
tion site.
It is very important to change filters regularly for performance and energy ef-
ficiency of the unit.
Each filter has a label with an part number for identification. Provide this
number when ordering new filters.
When it’s time to change the filters an alarm is shown on the control panel display. When this occurs do the following:
1. Stop the unit by disconnecting the mains.
2. Open the front hatch. See chapter 5.3.
3. Pull out the filters towards you. Some force may be needed.
4. Insert the new filters. Make sure that the correct filter types are inserted.
5. Close and lock the front hatch and connect the unit to mains.
6. Reset the filter time. See chapter 5.4.1.
