Installation, Operation and Maintenance Instructions
Weather-proof louvre, horizontal,
WSG-H3 for flat roof
Depending on the degree of soiling, clean the louvre at
regular intervals to remove leaves and similar deposits.
WSGs may be cleaned using compressed air, leaf blowers
or brushes. Make sure that as few solid particles (leaves,
twigs, etc.) pass through the top mesh grids. During clean-
ing work, it is absolutely forbidden to walk on the blades.
With very large and poorly accessible WSG-H3, we recom-
mend covering the louvre with a wooden board or similar.
Please make sure that the wooden board is long enough
and contacts the louvre frame on both sides and does not
rest on the blades. The wooden board can be positioned
so that it can be walked on during cleaning work. Suitable
safety measures must be taken to safeguard the cleaning
personnel (e.g. fall protection). This is the responsibility of
the operator.
ATEX:
Compliance is mandatory with all relevant inter-
national and national standards and regulations for Ex
zones.
These installation, operation and maintenance instruc-
tions are not a binding installation document for horizon-
tal weather-proof louvres and mounting frames. However,
possible flat roof connection examples are published
based on conventional flat roof structures.
The specifications contained in this document were com-
piled to the best of our knowledge based on current
knowledge and experience. LUCOMA reserves the right
to make changes at any time to match the current state
of production practice. These planning documents make
no claim to completeness. No legally binding obligation
can therefore be derived from them. Compliance is man-
datory with the local construction laws, standards and
regulations for design, component dimensioning, material
selection, laying, and governing heat, moisture, noise and
fire protection.

8 Exemption from liability
Safety checkpoint
– Ring screws are tightened firmly and aligned correctly
(avoid lateral pull)
– Ring screws are undamaged (corrosion, deformation, etc.)
– The slings have sufficient load bearing capacity and
they are undamaged
– The slings cannot come loose on their own from the at-
tachment point
– Additional restraints to secure the load are present
– Load must never be suspended over people
– The executing employee has received the needed training
These safety checkpoints are intended as guidance, and
they are not exhaustive. Regarding the safety regulations,
the local requirements must be observed. Lucoma AG
does not accept any liability for the load-bearing capacity
of the screws and the consequences of improper handling.
We recommend securing the loads additionally.
