DA 3800 Flange Inlet
16 Mounting Guide
3.4.3 Mounting inlet in wall
Make sure that the inlet flap is closed.
In the case of sloping walls, make sure not to tighten the
screws too much so that the inlet frame becomes
oblique, preventing the inlet flap from closing tightly. See
section
Oblique walls [
}
18] .
Place the inlet in the middle of the hole. Avoid pushing
the inlet into place during mounting.
Mount the inlet on the wall using screws.
Remember to use a spirit level.
Please make sure not to over-tighten the screws as they
are tightened directly against plastic.
To open the inlet, the differential switch on the flap must
be turned counterclockwise.
