ATEX
RGK 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 dampers in any way, the
ATEX approval becomes null and void. It is important to ensure
that the damper and additional equipment are installed in
compliance with zoning requirements.
In principle, avoid all damage caused by external influ-
ences. Never lift dampers by the slats or the outer
linkages. Dampers with a maximum weight of 50 kg
can be lifted by the C-profile frame. With heavier dam-
pers, use at least four points at the corner angles as
suspension points. Do not use individual slats under
any circumstances as footholds during installation.
Report any damage, e.g. deformation of slats, dents,

impacts or warping of the C-profile frame etc. imme-
diately to the supplier or manufacturer. This may im-
pair the proper functioning of the damper and at best
cause dangerous circumstances to occur.
ATEX:
Under no circumstances may ATEX dampers be
fitted after a fall or impact with visible or concealed
damage.
Mount the dampers warp-free, tension-free, on a flat
surface and without any angular errors in the damper
frame. When mounting, use the 4 corner holes provid-
ed as standard. With larger dampers, fit additional
flange couplings at spacings of 200 - 500 mm. This is
the responsibility of the planning engineer or fitter.
When installation is complete, check the angle of the
damper frame. It must be exactly 90°. Correct any
deviations immediately. In addition check the free
movement of the slats, linkage and gear wheels. Avoid
as far as possible any reduction in freedom of move-
ment on customer premises when installing insulation
materials, installation ducts, auxiliary structures etc. If
this is not observed, it can lead to considerable disrup-
tions in operation, e.g. slats rub against the damper
frame, increased damper torque, damper fails to open
or close, reduced leak tightness, fatigue fractures on
the axles etc.
Only dampers which are equipped with collar bushings
can be fitted with vertical slats (also called standing
slats). In addition, make sure with this damper appli-
cation that additional bolts or reinforcements are
affixed with dampers larger than 1000 x 1000 mm. The
lower frame profile on which the entire slat weight
rests must also be supported by the customer. Sagging
can lead to damper damage and plant outages.
On models with side seals (Di, DIN, CEN, S etc.) protect
the units from impurities of all kinds during the instal-
lation phase. Drilling swarf and concrete chips can
damage the side seals. Before starting up the dampers,
wipe the side seals thoroughly until they are dry.
