OUTSIDE ROLLER-BLINDS –VIVERA, HELUZ
1. CONTROL
Handle Strap/Cord Engine
DESCRIPTION OF THE CONTROL USING THE LEVER:
Grasp the lever, hold the lower part for better control and tilt the whole lever away from the wall. The blind
is lifted by turning the lever in an upward direction and downward in the opposite direction. After the blind
reaches the lower position, the lower bar is supported by the windowsill. After manipulation, put the level
into the original position and fix the lever into the holder.
DESCRIPTION OF CONTROL USING THE STRAP/CORD:
The blind is lifted by drawing the strap/cord in a downward direction to the roller. The strap/cord is
automatically wound into the winding unit by the spring. The blind is lowered by drawing the strap/cord
perpendicularly from the winding unit in the inward direction. The light holes are opened by slightly drawing
the strap/cord into the winding unit.
DESCRIPTION OF THE CONTROL USING THE ELECTRIC ENGINE:
Blinds can be lowered and rolled using the electric drive with the remote-control unit or the switch. In the
case of an electric drive, it is possible to use automatic control, such as the wind and solar sensor, depending
on the weather. In this case, an engine with a remote control is required. To set the electric control of the
blinds, follow the manual for this device that was delivered by the supplier.

Duration of the motor run
The motors used are not intended for long, uninterrupted
operation. The integrated thermal protection will deactivate the
motor after approx. 4 minutes.
The motor will return to the stand-by mode in 10–15 minutes.
Incorrect control
Do not control the shutter in a manner other than specified in
this technical manual.
NOTE:
Never attempt operating the shutter manually by force. This is
likely to cause permanent damage to the shutter.
Shutter movement
It is necessary to ensure the shutter area is free of any objects
and other obstacles that would prevent free downward and
upward movement of the shutter.
Operation in strong winds
Close the windows in strong wind conditions. Prevent draught,
especially if you are not present.
NOTE
The shutters are designed to withstand the expected wind
intensity without permanent damage. Both the window and the
shutters must be completely closed in strong wind conditions,
otherwise there is a risk of permanent damage to the shutters.

Operating the shutter at high temperatures
Sufficient ventilation of the curtain must be ensured if the
shutter is used as sun protection. In this case, lighting openings of
the shutter must be left open to prevent overheating, otherwise
there is a risk of permanent damage, especially in case of plastic
slats.
Operating the shutter at low temperatures
During cold seasons of the year and depending on current
weather conditions, the curtain may freeze onto the lower end
rail and/or lateral guide rails due to penetration of water during
thawing or rain/snow at low temperatures.
NOTE
In such cases, do not attempt to move the shutter by force. This
may lead to faulty function or permanent damage of the shutter.
Operating the shutter in the winter
If there is a risk of freezing onto surfaces, deactivate automatic
controls of the shutter.
EXCEPTION:
There is no need to deactivate shutter drives equipped with
overload sensors. If there is a risk of damage, they will deactivate
automatically.
Operating the insect screen
When releasing the insect screen in the upward direction, hold
the screen by both hands.
This will prevent damage by fast movement of the screen or by
hitting the stops.
