INSTALLATION, OPERATION AND MAINTENANCE INSTRUCTIONS
WSG GRILAIR WEATHER-PROOF LOUVRES
In principle, avoid all damage caused by external influ-
ences. Do not lift the louvres by the slats. Louvres with
a maximum weight of 50 kg can be lifted by the
C-profile frame. With heavy louvres use the ring bolt
suspensions provided. Do not use individual slats under
any circumstances as footholds during installation.
Any damage, e.g. deformation of the slats, dents, im-
pacts, frame warpage etc. can lead to insufficient
water drainage and undesired flow generated noise.
Report all damage immediately to the supplier or
manufacturer.
PRODUCT DESIGNATION

TECHNICAL SPECIFICATIONS
Max. size W x H: 1-part max. 4000 x 8000 mm (subject to shipping)
ATEX WSG dampers are only approved in specific designs and with
appropriate identification for Zones 1, 2, 21 and 22 according
to ATEX Directive 94/9/EC.
If the fitter or operator changes the louvres in any way, the
ATEX approval becomes null and void. It is important to ensure
that the louvres and additional equipment are installed in
compliance with zoning requirements.

INSTALLATION
Damage may impair the proper functioning of the
louvre and at best cause dangerous circumstances to
occur.
ATEX: Under no circumstances may ATEX louvres be
fitted after a fall or impact with visible or concealed
damage.
WSG-50 &WSG-75: These louvres are only suitable
for vertical applications. The louvres must be adequa-
tely sealed to fixtures and in the area of flanges. This is
the responsibility of the planning engineer or fitter.
WSG-h &WSG-SDf &WSG-SDs: These WSG mo-
dels require a base frame construction which must be
produced by the customer. With louvres which are
larger than 4 m² or with multipart louvres, the custo-
mer must produce additional support structures in the
area of the surrounding water duct. The planning
engineer or fitter is responsible for sufficient support.
The louvre is placed and fixed to the structure men-
tioned above. Make absolutely sure that all the sur-
rounding flanges are seated properly after the louvre is
positioned. To ensure drainage of water from the lower
slats, the louvre must be installed with a slight inclina-
tion in the direction of the slats.
The louvre is then ready to operate after an air duct
and water drains are connected without warpage.
ATEX: All relevant national and international stan-
dards and regulations for Ex zones must be observed.
On louvres with ATEX functionality in particular, the
louvre housing must be earthed using the earthing
braids attached by the manufacturer. No mechanical
changes may be made to the product. In addition do
not attach any components (frost monitors, tempera-
ture sensors, etc.) to the louvres if they have not been
analyzed for ignition risk by the appropriate manufac-
turers or approved for ATEX zones.
