SYSTEM 25
1. CONTROL
DESCRIPTION OF THE CONTROL USING THE CHAIN:
The blind is lifted and lowered using the chain. Drawing is always achieved by one chain in a
downward direction.
By drawing both chains at the same time, it can be damaged or can the body of the blind be pulled
out from the holders. The tilting of lamellas and regulation of light is performed by fi ne manipulation
with the chain. The lifting height of the lamellas is secured by catching the chain in the holder. For
versions of the blind fitted with a brake, the lifted lamellas are held in any position without the need
to secure the chain in the holder.
DESCRIPTION OF THE CONTROL USING CORD AND DRAWBAR:
The blind is lifted and lowered using the cord. First, release the brake by drawing the cord to the
center of the blind. The blind is lowered by releasing the cord; lifting into the requested position is
achieved by drawing in the cord. By drawing the cord into the center, the consequent release will fi x
secure the brake.
Tilting of lamellas and regulation of light is achieved by turning the draw bar. Recommendation:
when lifting and lowering the blind, tilt the lamellas into the open position.
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 manipulation, return the bar to the original position.
DESCRIPTION OF THE CONTROL USING THE ELECTRIC ENGINE:
The blind can be lifted or lowered by the electric drive, using the remote control or the switch. To set
the electric control of the blinds, follow the manual for this device that was delivered by the supplier.
