CONTROL AND MAINTENANCE MANUAL
* IN CASE OF EXTERIOR INSTALLATION, IT IS STRONGLY RECOMMENDED TO ROLL UP THE BLIND TO THE BOX IN
CASE OF ADVERSE ATMOSPHERIC CONDITIONS. FOR MOTORISED ROLLER BLINDS, IT IS RECOMMENDED TO USE
THE WIND SENSOR FOR AUTOMATIC BLIND ROLLING UP TO THE BOX.
DESCRIPTION OF ELECTRIC MOTOR CONTROL:
Screen roller blinds may be rolled down and up using an electric motor drive with a remote controller or a switch. With electric
drives, it is possible to use automatic control according to weather, such as the wind and sun sensors. In this case, a motor
with a remote controller is necessary. The electrical installation, assembly, and maintenance may only be performed by
qualified personnel, authorised and competent for the respective works.
The motor switches may be adjusted in two ways, either by a switch, or using a programme set (on request). Instructions for
the end switch programming and setting are specified in an individual manual.
2. MAINTENANCE
The product does not require extraordinary maintenance and lubrication of control mechanisms. For normal soiling, regularly
use soft brushing, hand-held vacuum cleaner set to low power, moistened soft textile fabric / sponge, or wash the surface with
clean water. Only use soap water solutions without chemical additives, up to 30 ºC (lightly soiled: 5% soap water solution,
water temperature up to 20 ºC; medium or heavily soiled: 10% soap water solution, water temperature up to 30 ºC). Do not use
aggressive cleaning agents like organic thinners, solvents, abrasive sand, cleaning pastes, steam generators and strong
alkaline cleaning agents.
We recommend performing regular checks and maintenance of the roller blinds. Before and after the season (spring, autumn),
we recommend:
Checking whether the roller blind rolls down and up correctly;
Checking proper function of the end switches;
Checking the condition of the cover –fabric, followed by cleaning, if necessary.
ATTENTION:
Always clean carefully to prevent damage to the frame and fabric. When cleaning the windows, always place the product in a
position that prevents damaging the product and does not preclude cleaning. Protect the product against soiling during
construction work and decorating.
3. SAFETY INSTRUCTIONS
Do not block the roller blind when moving. Remove your hands from the vicinity of the product before controlling.
Do not allow children to play with the control devices. Keep the remote controllers out of reach of children.
Regularly check the roller blind for deformation, excessive wear, or other damage.
Do not operate the roller blind during any maintenance works (such as window cleaning).

CONTROL AND MAINTENANCE MANUAL
If automatic control systems are used (like the sun / wind sensors), disconnect power supply before performing any
activities or maintenance.
Forced operation is likely to damage the roller blind.
Regularly check correct operation of the roller blind.
Do not use the roller blind if maintenance of the product is necessary.
Do not handle the product with force if its movement is prevented by an obstacle.
Do not hang any objects on the product and its control mechanisms.
Prevent mechanical stress and damage to the product.
The surroundings must be free of sharp objects or projections capable of damaging the fabric by tearing.
In case of cord-operated products, always keep the cords out of reach of small children to prevent entangling or choking.
Handle the product with care, especially during cleaning.
Never roll up wet fabric.
Immediately roll up the blind in case of change in the weather (announced or approaching storm, strong winds).

Do not allow children to play with the control devices. Keep the remote controllers out of reach of children.
Regularly check the installation for wear or damage to the supply cables.
Before performing any checks or maintenance of electric parts, always disconnect the product from electricity in a reliable
manner.
End switches may only be set up by persons who follow instructions for the motor operation.
Person who sets up the end switches must hold a certificate for electrical installation works, be skilled and experienced.
The operating time of the electric motor is strictly limited and must not exceed 4 minutes (= 20% of the cycle). The
remaining 80% of the cycle (approx. 16 minutes) is the period of mandatory motor cooling. Exceeding these conditions may
lead to permanent damage to the electric motor.
