6 Safety instructions regarding in-
stallation, operation, cleaning and
maintenance
DANGER Risks for children and people
with reduced physical, sensory or mental cap-
abilities or a lack of knowledge.
Unit may only be installed, commissioned,
cleaned and maintained by persons who can
safely recognise and avoid the risks associated
with this work.
DANGER Danger of electric shock from
operating the unit when not fully mounted.
Electric components are a potential source of
electric shock.
If the unit is open, all off the supply circuits must
be switched off (mains fuse off), secured against
being accidentally switched back on and a visible
warning sign must be attached.
Only operate the unit when it is completely in-
stalled.
DANGER Danger if the relevant regula-
tions for electrical installations are not ob-
served.
Before removing the housing cover or removing
the fan insert and before installing the electrics,
switch off all supply circuits, switch of mains fuse
and secure it against being accidentally switched
back on again. Attach a warning sign in a clearly
visible place.
Be sure to observe the relevant regulations for
electrical installation; e.g. DIN EN 50110-1. In
Germany, particularly observe VDE 0100, with
the corresponding sections.
Unit may be energized even when at a standstill
and may switch on automatically due to sensors
(time delay, humidity etc.). Maintenance and fault
finding only permissible when carried out by qual-
ified electricians.
The degree of protection stated on the rating
plate is only guaranteed if installation is under-
taken correctly and if the connecting cable is cor-
rectly guided through the stepped grommet (The
grommet must completely enclose the cable
sheathing). The fan insert must also be engaged
and the housing cover installed.
WARNING Risk to health if filters are not
replaced or if there are no air filters.
Heavily soiled or moist air filters can accumulate
harmful substances (mould, germs, etc.). This
may also happen if the unit is shut down for an
extended period. If the air filter is missing, the
unit and air ducts become soiled.
Never operate the unit without air filters.
Only use original filters.
Regularly change air filter when a filter change is
indicated (LED or TimeStrip).
If the unit has not been used for a long time, al-
ways replace the air filters.
WARNING Risk of injury when working at
heights.
Use appropriate climbing aids (ladders).
Stability should be ensured, if necessary have
the ladders steadied by a 2nd person.
Ensure that you are standing securely and can-
not lose your balance and that there is no one
under the unit.
