Introduction
Operation in winter (product with control system)
Products operated by a control system may start moving
at any time and without prior notice. After an impact with
condensation water, rain or snow the product can freeze up
with low temperatures. Operation of the product may cause
damage.
When using a control system without an ice alarm, the
automatic control mode should be switched off in winter.
Malfunction due to leaves or foreign objects
External sun shading systems are exposed to weather
and environmental influences. Depending on the location,
leaves and other foreign objects can cause the product to
malfunction.
Remove leaves and other foreign objects from the
beams, the inspection openings for the integrated
awnings and the awning fabrics.
Special feature of fabric (if present)
Fabrics can become electrically charged. Contact with
people or objects may result in an electrostatic discharge
from charged fabric.
Risk of damage to the product
An additional load can damage the product and/or cause it
to detach from its mount.
Improper handling may damage the product.
Do not hold onto the product or hang any objects on it.
It is not permitted to step on the product.
Never cover the radiant heater (e. g. with a towel, sheet,
etc.).
Do not touch the heating element of the radiant heater
with bare hands.
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 locations that frequently experience icy conditions,
the installation of an antifreeze device (e. g. gutter
heating) is recommended in gutters and/or pipes.
soiled drainage (for slat roof)
Gutters may clog with leaves, moss and dirt. This may
cause the gutters to overflow when it rains.
Gutters without or with an insufficient gradient must be
inspected and cleaned more frequently.

Product information
2.1
Intended use
The following details apply to the following product: slat roof
Lamaxa L60/L70
The product is a weather-proof, large-area external sun
shading system that may be used for protection against
heat and weather and for glare control. The product is used
to shade residential and commercial areas.
The rotatable slats can be used to reduce or prevent direct
sunlight from the top.
When closed, water is drained to one side via the slats and
is drained away via the drainage gutters on the beams and
into the poles. For structural reasons, the drainage gutter
does not have a slope and water may remain in the gutter
for extended periods.
Raindrops can enter the interior under the following
circumstances.
Heavier rain events than examined by WAREMA.
*
When the slats are opened after a downpour.
Rainwater splashing out of the drainage gutter.This can
be largely prevented by splash guards, but cannot be
avoided entirely.
Condensation that can form under the slats depending
on the weather.
Strong or changeable gusts of wind
Droplets can form on the frame and on the poles.
*
Examined rain event;
Lamaxa withstands a medium rain event
that occurs every 2 years for 5 minutes
[(350 l/(s*ha) equivalent to 126 l/(h*m²)]
Lamaxa withstands rain class 2 [56 l/(h*m²)]
Requirements:
a) 1 drainage present for a large Lamaxa
(order width x order length)
≤
16 m².
b) 2 drainages for a large Lamaxa (order width
x order length) > 16 m².
c) Free-standing slat roof Lamaxa. When
connected to the wall, facade water may
also be an issue, increasing the quantity
of water to the point where the tested rain
event is exceeded.
Inappropriate use may result in significant danger.
All closures and awnings intended for external use
are designed to handle a wind load of 1.1 kN/m² when
retracted.
The directive entitled "Wind loads for construction of
closures and awnings when retracted – Section 5.1.1"
defines the positions at which these products can be
installed without requiring special precautions [published
by the Bundesverband Rol Sonnenschutz e. V. and
ITRS Industrieverband Technische Textilien - Rollladen -
Sonnenschutz e. V.].
