1. MEASUREMENT
The blind can be positioned into or in front of the hole (on the ceiling or the wall).
THE WIDTH AND HEIGHT ARE MEASURED IN THE FOLLOWING MANNER:
Š.... (width)
a) fitting into the hole
The real width of the hole is measured, the value less than 5 mm than the real width of the hole is recorded in the order
sheet.
b) fixation on the hole
The width greater than the real width of the hole by 200 mm is written into the order sheet.
V .... (height)
The total height, including the upper profile, is measured.

ADDITIONAL INFORMATION
Determination of the maximum roller blind dimensions (width, height, area) depends on the type of fabric used (or on its
weight and dimensions).
The exact guaranteed limit dimensions for each type of fabric (by weight) can be found in the detailed table attached to the
order form.

Control lenght: Unless stated in the order otherwise, 2/3 of the height of the blind is selected as the standard variant.
The control length is equal to the desired height of roller blind for DAY/NIGHT fabrics.

2. ASSEMBLY
Assemble exactly according to this manual to prevent redundant assembly errors and other related problems.
AIDS FOR ASSEMBLY:
•tape measure
•spirit level
•electric drill as per the source material
•cordless electric drill
•magnetic adapter, bits PZ2
•hammer
•screws, dowels
INSPECTION:
•Before assembly we recommend inspecting all the parts after the delivery of the goods to prevent any problems. Any
defects or comments concerning the assembly or blinds must be notified to the manufacturer.
ASSEMBLY
•Check that the dimensions of the blind correspond to the width of the hole.
•Mark the place for the fixation of the side assembly consoles of the plastic parts of the blind (two anchoring places per
one part).
•Attach the side brackets by connecting elements and firmly tighten so that the outer distance between the brackets is
the required width of the roller blind.

•To the assembled brackets on the side without the control mechanism, insert the tube pin of the roller blind (for Verra
with marking plastic, for Verra Metal with marking metal).
•Insert the tube with the fabric aside without the control mechanism on the inserted pin, and then insert the side with
control mechanism into the bracket before we hear the click (be careful about the metal / plastic orientation).
•Fit the bracket caps depending on the roller blind type (Verra –plastic cap, Verra Metal –metal cap).
•Set the lower end position using the second chain joint.
•Check the roller blind function and the brake operation.
ASSEMBLY WITH THE MOUNTING PROFILE:
For the Verra and Verra Metal roller blinds with the mounting profile, the roller blind is delivered in assembled condition
from the producer. During the actual assembly, it is only necessary to place mounting clips (into which the roller blind itself
clicks) on the wall or ceiling, at the proper distance, into which the roller blind itself clicks. After that, i tis only left to check
the lower end position and the total functionality of the roller blind.
ATTENTION!
FOR VERRA METAL ROLLER BLIND WITH FABRIC DAY/NIGHT THE ROLLER BLIND IS PROVIDED WITH THE
MOUNTING PROFILE WITH THE MOUNTING CLIPS.
NUMBER OF THE CLIPS:
Roller blind width (mm)
Clips number (pc)

The first clip must be always placed at a distance 40 –50 mm from the edge of the roller blind.

ATTENTION!!!
Pursuant to the EN 13120:2014 standard, window blinds shall be installed in
accordance with the following instructions:
In the case of a disintegrating coupling, the chain length
must be liminited as follows.
1) If assembly height (H0) is not specified, the
chain length (H2) shall be less than or equal to
2/3 of the blind height (see Fig. 1): H2 ≤ 2/3 H.
2) If assembly height (H0) is specified, the
distance from the floor to the bottom part of the
pull cord (H1) shall be at least 0.6 m: H1 > 0.6
m.
A dangerous loop must be eliminated when a mass of 6
kg is applied or within 5 seconds of application.

If the winch is used, the roller blind must meet below mentioned requirements.
In the fully extended position, the length of the cord (cords) must be limited (the winch must be positioned as follows):
If the asembly height H0 is not specified, and
i) if the aperture height H is less than or equal to 2,5 m, the length of the cord (cords) H2 must be less than or equal to (see
picture): H2 ≤ 1 m.
ii) if the roller blind height H is greated than or equal to 2,5 m, the length of the cord (cords) H2 must be less than or equal
to the screen height minus 1,5 m (see picture): H2 ≤ H - 1,5 m.
If the assembly height H0 is specified, the distance from the floor to the bottom of the cord (cords) H1 must be at least 1,5
m (see picture): H1 > 1,5 m.
