* Clip mounting
These guide rails have two small L-shaped notches on the back. These are either used for clipping the guide rails to the
window frame, using the provided clips, or they are fitted with sealing strips.
The clips must be screwed on each side of the window frame in one straight and vertical line.
** Sealing strips
When the screen is mounted to a window frame on which the surfaces for the two guide rails are not flush, the resulting
gaps between the guide rails and the window frame can be sealed with sealing profiles.
These sealing profiles must always be secured by a screw at the top and the bottom of the guide rail. Be careful when
tightening the fasteners, because overtightening can permanently damage the sealing profiles.
In the interest of safety, it is important that each guide rail be additionally secured to the window frame at the top,
middle and bottom with a sheet metal screw to prevent the guide rail from sliding and the clips from detaching
from the screen.
*** Distance supports
For guide rails with a mounting flange (type 828), distance supports can be used for mounting the guide rails.
**** Cover cap
For each of the guide rails of the type referred to above, use a cover cap at the bottom end. This will prevent the bottom
slat from dropping out of the guide rails.
U-shaped guide profile:
A plastic screen guide profile fits into the U-channel of each guide rail, which accommodates the zipper on the fabric.
(At the top end of this extrusion, the black rubber part is cut away at an angle over a length of 70 mm.
Make sure the guides are positioned with these cut-aways at the top. The screen guide profiles for the left and right sides
differ.)
2.5. PIN MOUNTING
In this installation the box is mounted onto the guide rails by sliding the pivots on each of the side consoles into the
corresponding hole chambers on the guide rails.
To make some of the following steps easier, it is recommended that you unroll the screen a bit so the bottom slat extends
a few centimetres from the box. To do so, use a test cable to briefly operate the motor or operate the manual gearbox with
a crank handle attached to a square rod inserted through the opening in the box.
Based on the installation situation, there are several ways the screen can be installed:
Method 1. Affix the box using the mounting brackets, then slide the guide rails onto the console pivot and secure the guide
rails with screws.
Method 2. Place the complete box / guide rail assembly in or against the window opening and screw them in place.
Mehtod 3. Screw the guide rails in place. Then push the box onto the guide rails and secure it in place.

Step 2: Installing the box on the mounting brackets
One mounting bracket per console, as close as possible to the console.
Any additional brackets are mounted in the middle of the box, evenly spaced across its width, and are intended to prevent
wider boxes from sagging.
(1) Push the box upwards into the mounting brackets.
(2) Feed the motor cable through to the inside. Then push the box into the brackets so the slots in the back of the box
engage with the L-profiles.
(3) Next tighten the Allen screws of each bracket. The screws should grip in the slots at the top of the front of the box.
Step 3: Drilling the mounting holes for the guide rails
Mark the holes to be drilled on the wall or on the
mounting surface. Use the pre-drilled lateral guide rails
for this procedure. Drill the holes in the wall (Ø6 mm)
or in the window frame (Ø3.2 mm).
For installation to the wall, insert S6 plugs into the
holes.
Step 4: Installing the guide rails
(1) Affix the clips to the mounting surface. Next slide the guide
rails onto the guide rail pivots of the side consoles. Make
sure the sliding blocks of the bottom slat enter the guide rail
slots correctly and the zipper on the fabric slides into the U-
shaped part of the plastic guide profile.
(2) Screw the guide rails to the mounting surface.

Make sure the box is always securely mounted. See section „Installation of controls“.
2.6. CHECKING FOR SQUARENESS
Always make sure the screen is installed perfectly level and square.
There is only one way to check and correct this.
1. First check whether the box is mounted perfectly level.
2. Check whether the guide rails run parallel to each other and
perpendicular to the box. Measure the diagonals to the
nearest millimetre. Start directly beneath the box. Deviations
of more than 2 mm may cause the fabric and/or bottom slat to
get stuck or the fabric to hang loosely.
3. Next measure the diagonals to the nearest millimetre.
If the box and guide rails are not mounted properly, the bottom slat will
always roll into the box at an angle, resulting in diagonal creases in the
fabric.
Once the screen has been accurately positioned and mounted, any small gaps between the guide rails and wall (box and
wall) can be sealed with silicon caulk.

3. GENERAL INFORMATION
3.1. CHECKING THE INSTALLATION
The installation is checked by testing its functionality. The screen is lowered and raised again. This should proceed
smoothly, and no creases should develop during lowering.
3.2. MOUNTING THE BOX
This can be done in several ways:
Secure the box by hanging it from the mounting brackets (see method 1), or
- Open the box. Remove the fabric roll from the box by tapping upwards on the fabric roll so the end pops out of the
click-in retainer. Affix the box to the mounting surface with the extra pan head screws (through the back or the top of
the box). Do this for each console and in the centre. Re-install the fabric roll and the box cover.
3.3. FINISHING
Space between screen box and wall
Apply a small amount of silicon caulk in the gap between the screen box and mounting surface in order to prevent any
potential movement.
To fill the gaps at the top and the sides (between the screen box and the mounting surface when mounting brackets
are used), you can use joint sealing strip or the special U-profile (see points G3 and G4) which is available separately..
Space between guide rails and wall
Apply a small amount of silicon caulk in the gap between the guide rails and mounting surface in order to prevent any
potential movement.
DVC/DVS
When installing DVC/DVS linked screens, it is recommended that one person be available to push each guide rail onto
the console pivot, the bottom slat into the guide rail and the zipper into the grey U-shaped part of the plastic guide
profile.
4. INSTALLATION OF CONTROLS
4.1. ELECTRICAL CONNECTIONS
Note: The connections must be made by a qualified installer (refer to guarantee card 2.1). Electrical installation and
connection diagrams must be followed correctly. The electrical accessories employed must comply with the current
standards and/or requirements.

4.2.1. WIRING DIAGRAM FOR A SINGLE POLE SWITCH
The motor has 4 wires. Yellow/green (earth), blue (neutral), brown and black (up and down control). There should be three
wires available from the protected mains circuit. Yellow/green (earth), blue (neutral) and phase wire. Connect the wires
according to the diagram. The phase wire from the electrical mains is connected to terminal L. If necessary, exchange the
brown and the black wires from the motor at the switch so that the arrows on the switch correspond to the up and down
movement of the screen. The two earth wires are connected together by means of separate wire clamps. The same
applies for the two neutral wires.
Connecting and installing the motor:
Lead the motor cable to the control switch until it is out of sight where
possible.
Connect the motor cable and the power supply to the single pole
switch. See above.
Exchange the brown and black wire if necessary so the arrows on the
switch correspond with the movement.
When two or more motors are connected to a single switch, use of
one or more relay boxes is required. Refer to diagram RI2 for making
the connections.

Remark concerning the motor:
If the motor is of the standard LT type, you can continue following the instructions in this manual. For the LS motor, the
stop positions are not set with push buttons but rather with Allen key setting pins (consult the accompanying manual).
If an Altus RTS type is used, consult the instructions that accompany the motor.
4.2.2. CALIBRATING THE MOTOR –LIMIT SWITCHES
Temporarily connect the test cable to the motor.
4.2.2.1. LOWERING THE SCREEN WITH THE MOTOR –SETTING THE END POSITION
DOWN
Lower the screen with the motor. Make sure it stops at the correct point and not past the lower stop position, as the screen
could otherwise be rolled up in reverse, causing damage.
The motor limit switches have not been calibrated. Both buttons on the motor have been completely pushed in at the
factory (or press them both in if that is not the case). As a result, the motor will not stop on its own.
Lower the screen until the desired bottom position has been reached. Then put the switch in its neutral position.
Now push the white button (or yellow button, depending on the orientation of the motor) so the button pops out slightly.
The lower stop position has now been set.
4.2.2.2. RAISING THE SCREEN WITH THE MOTOR –SETTING THE END POSITION UP
Now raise the screen with the motor. Make sure it
stops in time, just below the upper stop position.
Then put the switch in its neutral position.
Now push the yellow button (or white button,
depending on the orientation of the motor) so the
button pops out slightly. The upper stop position has
now been set.
The two stop positions have now been set.
If it becomes necessary to calibrate the motor stop
positions again, the procedure can be repeated by
simply pushing in both buttons. This clears the stop
position settings so new settings can be made by
following the instructions beginning at 4.2.2.
Why use an RI2 relay box?
If several LT or LS motors are operated using the
same switch, you must always use a relay box. If
relay boxes are not used, the system will oscillate
and the resulting high inductive and capacitive

voltages will burn out the switches inside the motor housing.
Thus heed the following advice: Always use the relay boxes and switches supplied by us, to control two or more motors
with a single switch.
The same applies when using an wind/sun automatic controller.
4.2. FITTING THE CRANK HANDLE LEAD-THROUGH, INDOORS –FOR CRANK
HANDLE OPERATION
Push the supplied crank handle lead-through with the 6x6 mm square rod through the previously drilled opening until the
rod is pushed far enough to engage with the gearbox. Determine the required length of the rod and shorten it if necessary
by sawing off the surplus length.
Position the lead-through in such a way that the rod will not rub against the opening anywhere along its length. Also make
sure the rod goes straight through the opening and is neither bent nor twisted. Drill the holes (Ø3.2 mm) and fasten the
lead-through to the mounting surface.
Push the crank handle over the spherical part of the lead-through and insert the split pin or solid pin to join the two parts.
Slide the locking bush over the pin.
Determine where the magnetic holder should be positioned on the window frame or the wall and screw it in place. Make
sure the metal part of the unfolded crank handle contacts the magnetic holder.
If you are installing a detachable rod with a rod coupling: the detachable crank handle is fitted with a cone-shaped end
piece. A split pin is then inserted into the free-hanging spherical part of the lead-through. The crank can then be attached
or detached from the crank handle with a twist of the handle.

4.3. CRANK HANDLE OPERATION WITH EYE –FOR OUTDOOR OPERATION
In this case, the screen box is fitted with a long, metal eye. A crank handle rod with a hook can be hooked onto this to
operate the screen.
After operating the screen, unhook the crank handle rod and store it indoors in a dry area.
5. INSTALLATION OPTIONS
5.1. FITTING THE U-CHANNEL 10X10X10X1.5 MM, HORIZONTAL
If a loose U-channel is supplied, it can be used to conceal the electrical
cable for the motor so that the cable can run on top of or behind the
box from one side to the other. Press the cable into the U-channel and
apply a thin layer of silicone caulk to one side of the U-channel, then
press the side of the channel with the caulk flat against the top of the
box, neatly aligned and parallel to the rear edge of the box.
5.2. FITTING THE U-CHANNEL 10X10X10X1.5 MM,
VERTICAL
To fill the gap behind the box in line with the guide rails, you can use a
U-channel that is available separately.
Attach the U-channel to the back of the box with caulk, with the back of
the profile in the same plane as the console.
5.3. FITTING THE 30X20X2 MM ANGLED PROFILE
