Assembly of the ALFA-ZIP and ALFA PLUS-ZIP screen roller shutters
There are several methods of roller blind installation depending on the installation situation.
Note: For the self-supporting version of the screen roller shutter assembly, please refer to Variant A,
Method 2.
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 guide 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 presence of a window sill, or for the self-supporting
version of the screen roller shutter).
METHOD 1. Attaching the box using wall/ceiling holders, sliding the guide
rails on the side piece pin, and securing the guide rails by bolts.
Step 1: Drilling the holes for the wall/ceiling holders
1. Place the wall/ceiling holders to the assembly
surface. Use the upper holes for ceiling
mounting, and the rear holes for wall
mounting.
2. 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 another suitable tool.
3. The wall/ceiling holders must be installed 40–
100 mm from the box sides. Any additional
holders are to be installed 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. Remove the front cover of the box.
2. Fit the box to the wall/ceiling holders.
3. Make sure the box is correctly fitted to all
holders.
4. Fit and push the safety locks; they must click
to correct position.

Step 3: Centring the fabric in the box
1. Unroll the fabric completely from the roller (the fabric remains slid in the roller groove). Doing
this, prevent soiling of the fabric and damage to the lower profile.
2. Centre the fabric in the roller so that it is in the centre of the box (not in the centre of the
roller).
3. Check whether the fabric rolls up evenly → perform 2–3 control cycles. (CAUTION! End
positions of the motor have not been set yet!)
End the check by moving the lower rail approx. 15 cm under the box.
Step 4: Drilling holes for the guide rails
Guide rails A839, A829:
1. Indicate holes to be drilled to the wall or another assembly surface.
2. Use predrilled guide rails to do this.
3. A indicates holes for attaching the guide rails (see Fig. below).
4. B indicates holes for the holders (see Fig. below).

Step 5: Installing the guide rails
Guide rails A839, A829:
1. Attach the holders to the assembly surface.
2. Click the guide rails to the holders head-on.
3. Slide the guide rails to the side piece pins and make sure whether the bottom slat end pieces
fit properly in the guide rail slots and whether the fabric zipper fits in the plastic insert in the
bottom slat.
4. Attach the guide rails to the assembly surface through holes A.

Step 6: Attaching the front cover
Reinstall the box front cover.
Step 7: Adjusting the motor
Set the end positions of the motor depending on the motor type (see manuals for motors).
Step 8: Checking the assembly
Always make sure the roller blind is properly
installed:
1. First, check horizontality of the box.
2. Check whether both guide rails are parallel to
one another and, at the same time,
perpendicular to the box.
3. Measure and compare the diagonals
accurate to the nearest millimetre.
If the box and guide rails are not installed correctly,
the bottom slat will wind into the box at an angle,
causing the fabric to crinkle or pull out from the
plastic insert in the guide rail.

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 presence of a window sill or for the self-supporting version
of the screen roller shutter).
Step 1: Drilling the holes for the wall/ceiling holders
1. Place the wall/ceiling holders to the assembly
surface. Use the upper holes for ceiling mounting,
and the rear holes for wall mounting.
2. The box must be perfectly horizontal, and
therefore make sure whether the wall/ceiling
holders are properly aligned. To do this, use a

3. The wall/ceiling holders must be installed 40–100
mm from the box sides. Any additional holders are
to be installed evenly distributed along the box
width and they are intended to prevent arching of
wider boxes.
For the self-supporting version, skip Step 1 and continue
to Step 2.
Step 2: Drilling the holes for the guide rails
Guide rails A839, A829:
1. Indicate holes to be drilled to the wall or another
assembly surface. Use predrilled guide rails to do
this.
2. A indicates holes for attaching the guide rails (see
Fig. below).
3. B indicates holes for the holders (see Fig. below).

Step 3: Sliding the guide rails on the side piece pins
1. Place the roller blind box on the cardboard packaging
(take care not to damage the surface treatment).

with at least two other persons depending on the box
width.
2. Place the complete assembly to the window opening.
