Spirit level
Place the wall/ceiling holders to the assembly surface.
Use the upper holes for ceiling mounting, and the rear
holes for wall mounting.
The box must be perfectly horizontal, and therefore
make sure whether the wall/ceiling holders are properly
aligned.
To do this, use a tube spirit level and a plumb line, or ano-
ther suitable tool.
The wall/ceiling holders must be installed 40–100 mm
from the box sides. Any additional holders are to be in-
stalled evenly distributed along the box width and they
are intended to prevent arching of wider boxes.
Step 2: Installing the box to the wall/ceiling holder
1. Fit the box to the wall/ceiling holders.
2. Make sure the box is correctly fitted to all holders.
3. Fit and push the safety locks; they must click to correct
position.
Installation of ALFA PLUS screen roller blind:
There are several methods of roller blind installation depending on the installation situation.
Variant A: Using the wall/ceiling holders
Method 1. Attaching the box using wall/ceiling holders, sliding the guide rails on the side piece pin, and securing the gui-
de rails by bolts.
Method 2. Placing the complete assembly of the box and guide rails in or above the window opening and securing by
bolts (used where there is insufficient space for sliding the guide rails on the side piece pin, for example due to the presen-
ce of a window sill).
