Operation in the event of a power supply failure
An electrically-operated product cannot be operated without
power. A lowered/extended product may be subjected to
impermissible loads when bad weather fronts pass over
and during power failures. This may also result in serious
injury to persons and/or damage to the product.
Manual emergency operation or an emergency power
supply should be considered for windy regions with
frequent power failures.
Accessing the operating element (electrically operated
product)
The operating element is not intended for children to use.
Children are unable to recognize the danger associated
with the product. Persons can become injured from
careless use.
Do not allow children to play with the locally installed
control system or operating element.
The hand-held transmitter must be kept out of the reach
of children.
Operation in wind
The product is only able to withstand the loads associated
with the specified wind resistance class.
The product must be retracted when the specified wind
resistance class is exceeded.
The product should not be moved in any other way
under heightened wind loads.
Operation in icy conditions/winter (general procedure)
Operating the product at temperatures at or below the
freezing point may result in malfunctions and/or damage
if the installation and building situation is unfavourable.
Moisture on the product due to dew, rain or snow can cause
the product to freeze up at low temperatures.
Before operating the product, it should be cleared of
snow and ice so that it can move freely.
Before operating the product, the grooves of the guide
rails should be freed of snow and ice so that the product
can move freely.
Do not operate the product under icy conditions.
Operation in winter (product with control system)
Products operated by means of a control system may start
moving at any time and without prior notice. Moisture on
the product due to dew, rain or snow can cause the product
to freeze up at low temperatures. Operation of the product
may cause damage.
When using a control system without an ice alarm, the
automatic function should be switched off in winter.
Risk of damage to the product
An additional load can damage the product and/or cause it
to detach from the wall.
It is not permitted to hold onto the product or to lean
objects against it.
Freezing of drainage channels in winter
In winter, snowfall may occur. Heat from the sun will begin
to melt the snow. In cold and shady areas, melt water will
refreeze. Down pipes may freeze and burst open.
In areas where temperatures are frequently below
freezing, the installation of an antifreeze device (e.g.
gutter heating) is recommended in gutters and/or pipes.
Dirty drainage pipes
Gutters may clog with leaves, moss and dirt. This may
cause the gutters to overflow when it rains.
Installation of a leaf guard is recommended to prevent
the accumulation of debris in the down pipe.
Gutters without or with an insufficient gradient must be
inspected and cleaned more frequently.
