Important safety information for users
Dear MHZ Customer,
Congratulations on choosing your new, high-quality MHZ product.
When it comes to safety, MHZ metal blinds are state of the art. How-
ever, we feel it is our duty to ensure you are familiar with the safety
information given here. Follow the operating instructions and your
product will continue to serve you well for many years to come
1. Reading the operating instructions
You must read the operating instructions before using the
 metalblindforthersttime.Itisimportanttofollowthese
instructions to ensure people’s safety.
Any failure to do so absolves the manufacturer of any liability.
All instructions are to be kept by the customer for future refer
ence and must be passed on to the new owner if the metal
blind is sold.
2. Safety and warning notes for the operating instructions
Safety notes can be found throughout the text. They are
marked with various symbols and text:
Important safety note:
Notes that are important for the functioning of the product and
can result in serious injury or death if they are not observed are
marked with this warning triangle.
Important safety note:
Notes that represent a risk of electrocution that can result in
serious injury or death if they are not observed are marked with
this warning triangle.
3. Product identication
EveryoneofourmetalblindsisidentiedbyaCElabel.
The label forms part of the product and must not be removed
as it may be required to identify the product at a later date.
See Point 18 “Explanation of the CE label”. It is attached to the
inside of the drop bar.
4. Intended use
The metal blind is a sun protection unit that must only
be used as intended to protect against the sun. Misuse can
lead to considerable danger.
 Changes,suchasattachmentsandmodications,notintended
by the manufacturer may only be carried out with the manufac
turer’s written consent.
Applying additional loads to the metal blind by attaching ob
jects or through cord tensioning can result in it becoming dam
aged or falling down and is therefore not permitted.
5. Operation
Children and people who cannot accurately assess the
risks of incorrect or improper use must never operate the
metal blind. Store remote radio controls in a place that is out
of their reach.
When retracting or extending the metal blind, make sure
there are no people or obstructions blocking its path of travel
or touching it. When retracting or extending the unit, there are
crush and shear zones around the drop bar and the side guide
rails (caution – risk of injury).
Refer to the separate adjustment and operating instruc
tions issued by the motor, switch and control manufacturers
and enclosed with the metal blind before you use it for the
 rsttime.
Never push the metal blind up by hand, as this can cause
irreparable damage to the blind.
6. Automatic control
A metal blind must never be extended unsupervised.
An automatic control may fail under extreme conditions (e.g.
power failure, defects, sudden storms). There is a risk of the
metal blind becoming damaged or falling down.
The automatic control must be set to manual operation during
frosty periods.
Recommendation: Set the automatic control to manual opera-
tion and retract the metal blind whenever you are going out.
7. Use in windy conditions
The metal blind meets the requirements of the wind resist
 anceclassspeciedintheenclosedCEconformitymark(see
Point 19 “CE conformity mark”).
The wind resistance class achieved after installation depends
largely on the type and number of fasteners and the sub-con
struction.
The metal blind must only be used up to the wind resistance
class declared by the installation company.
 Thismaynotbethesameasthewindresistanceclassspecied
by the manufacturer.

8. Use in snow and ice
Do not extend the metal blind during snowfall or when
there is a risk of frost. There is a risk of the metal blind becom
ing damaged or falling down.
If condensation has formed on the metal blind when it
is retracted or extended, the blind may freeze up at temper-
 aturesaroundfreezing(≤4°C).Ifablindthathasfrozenupis
retracted or extended by pressing the switch or by a command
from the automatic control, this will inevitably damage the
metal blind beyond repair.
The automatic control must always be switched off when
 thereisariskoffrostandduringwinter(≤4°C).
9. Leaves and debris
Remove any leaves and other debris that has accumulat-
ed on the unit immediately. There is a risk of the metal blind
becoming damaged or falling down (switch the controls off).
10. Obstructions
There must be no obstructions within the metal blind’s
range of extension. They would pose a risk of people being
crushed or the metal blind becoming damaged beyond repair.
This applies to access doors and windows with protruding sills
in particular.
11. Cleaning and maintenance work within the metal blind’s range
of extension
Motor-operated metal blinds may start up unintentional
ly. Make sure the metal blind is disconnected from power (e.g.
by taking out the fuse) when performing any cleaning or main
tenance work (such as cleaning glass surfaces).
If the metal blind is operated by several users, a priority locking
system (externally controlled circuit breaker) must be used,
which makes any retraction and extension of the metal blind
impossible during cleaning and maintenance work.
12. Care and cleaning
Frame:
All aluminium parts are powder-coated and therefore weath
er-resistant. We still recommend cleaning the aluminium parts
with water and a commercially available cleaning agent at
regular intervals (do not use aggressive agents).
Metal blind
Depending on where they are installed, the surface of our
metal blinds can easily become soiled due to external environ
 mentalinuencesandexhaustgasesfromindustryandroad
 trafc.Thissurfacesoilingdoesnotimpairthetechnicalfunc
tion of our product.
We recommend cleaning the blind at least once a year.
We recommend taking the following steps to prevent soiling
on windows and facades:
First use a dry, soft brush to remove dirt and contamination,
then follow up with a damp, soft sponge. We recommend using
pH-neutral water to prevent water spots forming on the surface
of the blind.
n Use a dry, soft brush to remove coarse surface dirt
(do not rub or scratch).
n Clean the outside of the blind by working horizontally
from top to bottom.
n Then dry the outside of the blind.
n Never clean with chemical or abrasive agents, or with
very hard tap water.
n Clean using moderate pressure (never use high-pressure
cleaners).
n Never clean when there is a risk of frost.
n The manufacturer cannot accept any liability for improper
cleaning.

13. Maintenance
Safe and reliable use of the metal blind can only be
guaranteed if the unit is checked and maintained on a regular
basis. The maintenance instructions and maintenance intervals
must be observed.
The general safety regulations regarding personal protective
equipment (PPE) and the use of ladders must be observed.
Only use approved climbing aids (ladders).
The following should be carried out regularly, but at least
once a year:
n Visually inspect the blind for any damage
n Inspect the top and bottom end positions of the blind.
The end positions may need to be adjusted at the motor.
n Inspect the installation of the guide rails as well as the foot
and installation brackets.
n Inspect the drop bar to ensure it is positioned centrally.
The drop bar must not be pushed right up against the
guide rail on one side or the other. You may need to use
the adjusting device on the top bearings to align the
roller blind tube.
n Inspect the side guides and gliders for signs of wear.
 n Inspect the power cable for damage and wear.
If damage is detected, the specialist retailer or a
suitable service company must be commissioned to carry out
the repairs. Retract any metal blinds in need of repair and do
not use them (switch automatic controls off).
14. Spare parts
Only use spare parts authorised by the manufacturer.
15. Taking down and disposal
To take the metal blind down and dispose of it, follow the
installation instructions in reverse order. Please note that the
 blindisheavy(approx.5.2kg/m²).CommissionanMHZspecial

Example: s_enn
Maximum permissible wind speed at which the unit can be used
Resistance to wind load
ThewindclassesdenedbyDINEN13659donotpermitanycon-
clusionstobedrawnonusability(extending/retracting,intermedi-
ate positions, etc.) under actual wind loads. The manufacturer must
thereforedenethemaximumspeedabovewhichthemetalblind
must be retracted taking into consideration the installation situation
and the blind clearance. This wind speed must be stated in the tech-
nical documentation (e.g. operating instructions). The conditions to
becompliedwithtoensurethattheperformancespecicationsare
fullledarebasedonstaticloadsanddonottakeaccountofany
dynamic effect of repeatedly applied loads (turbulence) to which
the metal blind and frame are exposed during actual use. The static
pressure can therefore not be used to determine how to anchor the
metal blinds to the building.
Thesubstructure/distancetothefacade/height/cornersituationalso
hasaninuenceonthemaximumpossiblewindspeedandisnot
taken into account in the standard (DIN EN 1932:2013-09 External
blinds and shutters – Resistance to wind loads – Method of testing
andperformancecriteria)althoughthesefactorshaveasignicant
impact on the product’s resistance to wind loads.
Note regarding applicability
The wind speeds used in the following table only apply with win-
dows closed and not in corner situations. Similarly, the positioning
and number of wind monitors used are of vital importance in se-
lecting the appropriate wind speed for the building in question. In
particular, the building’s geometry and location must be taken into
consideration. For this reason, it is essential to consult the specialist
planner in such situations.
