Maximum permitted wind strength

The sun protection system has been constructed so that the largest size meets the
minimum requirements for wind resistance class 2 in the CE conformity classification
(see table 1.4). Depending on the projection, it may also meet resistance class 3. The
wind resistance class after the system has been installed depends largely on the type and
quantity of fixing materials used and the surface it is installed upon. The sun protection
system may only be used up to the wind resistance class declared by the installer.

2.0 General operation

• There should be no people or obstacles in the way of the sun protection system when
it is being extended or retracted. Never let children operate the sun protection system
or any control unit. The operator must be able to see the sun protection system while
operating it.
• For manual operation, the shaft of the operating handle must be used in the same
direction as the gearbox ring when extending or retracting the sun protection system.
Force should not be used to retract sun protection systems with operating handle
drives. Do not continue to turn the operating handle when the end position has been
reached.
• Moving parts of the sun protection system must not be touched when it is being ex-
tended or retracted.
• To prevent damage, the sun protection system should not be used if it snows, because
of the load, or is icy or frosty.
• No additional weights, such as hanging clothes or flower pots, should be placed on the
sun protection system.
