Installation information
• Cover can be turned up to ± 5° (to provide com-
pensation if housing is inserted at too much of
an angle). If installing on a wall, ensure that the
Maico name is in the bottom right.
• If the housing edge is flush with the plaster, use
central screw, M6 x 16 mm, to secure the
cover.
• With a plaster overshoot of up to 20 mm to the
housing edge, use spacing frame DR 60/100
between the wall and cover. The customer
should provide a longer screw (M6 fillister head)
to secure the cover.
• If the housing is plastered in too deep, com-
pensate for this with a two-part wall frame ER-
MR (can be adjusted between 50...100 mm).
This prevents air from being drawn in from the
shaft. Use the supplied screw to fix the cover.
1. Fold up cover at the recessed grip, place on
the housing and secure with the central screw.
2. If necessary, first fit a spacing or wall frame.
3. With second room extraction, insert regulating
plate below locking tabs at the side on the in-
take grille of the cover, insert filter mat.
4. Lock cover. The lock must engage audibly.
5. Switch on mains fuse, remove warning sign.
6. Undertake initial commissioning and function
test.
