ateX DRK and RSK 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 lin-
kages. 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-
shiPment
installation
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
These dampers can be fitted or removed to or from a
wall or an air conditioning system, or integrated in a
duct section. First make sure the air flow is in the pro-
per direction as indicated by the red arrow on the
damper housing. Mount the dampers warp-free, ten-
sion-free, on a flat surface and without any angular
errors in the damper frame. When mounting, use the
4 corner holes provided as standard. With larger dam-
pers, fit additional flange couplings at spacings of
200-500 mm. This is the responsibility of the planning
engineer or fitter. During installation, make sure that
the slats are exactly horizontal. The damper must be
adjusted exactly vertically (for horizontal air flow) or
exactly horizontally (for vertical air flow).
When installation is complete, check the angle of the
damper frame. It must be exactly 90°. Correct any de-
viations immediately. In addition check the free move-
ment of the slats, linkage and tripping mechanism.
Avoid as far as possible any reduction in freedom of
movement on customer premises when installing insu-
lation materials, installation ducts, auxiliary structures
etc. If this is not observed, it can lead to considerable
disruptions in operation, e.g. slats rub against the dam-
per frame, different tripping pressure, damper fails to
open or close, reduced leak tightness, etc.
On models with side seals (Di, DIN, CEN 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.

ateX: All relevant national and international stan-
dards and regulations for Ex zones must be observed.
On dampers with ATEX functionality in particular, the
damper 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 (motors, limit switches,
etc.) to the damper if they have not been analyzed for
ignition risk by the appropriate manufacturers or ap-
proved for ATEX zones. It is prohibited to drill holes or
fit bolts or screws in the interior of the dampers. This
could lead to damage or disturb damper operation. If
there is a risk at the factory that foreign bodies may
enter the movement area of the slats, prevent them by
suitable means (filters or catchment grills). This pre-
vents the slats from sticking and the possibility of
frictional heat developing.
rsK: Back-draught dampers have no specified open-
ing pressure.
drK: The tripping pressure is adjusted according to
customer specifications on a test stand at the manu-
facturer›s factory. After installation, the tripping pres-
sure may be readjusted within a limited range as
required. This occurs by sliding the tripping weight on
the lever and refixing it in the required position. If the
weights are arranged above a passageway, it is impe-
rative to install a suitable catchment device.
Depending on the degree of soiling of the medium,
carry out a dry clean from time to time; the seals in
particular must be cleaned at regular intervals. In addi-
tion, operate the dampers at regular intervals to test
for their operability depending on the specific plant
conditions. This prevents the adjacent slats from sti-
cking. The slide bearings can be blown off using com-
pressed air as required, although they are basically
maintenance-free (lubrication). Otherwise the DRK
models operate maintenance-free.
Only LUCOMA genuine spare parts may be used for all
repair and maintenance work.
ateX: All relevant national and international stan-
dards and regulations for Ex zones must be observed.
Before using LUCOMA dampers in areas with increased
requirements, report the prevailing conditions to the
manufacturer so that the correct damper materials
can be selected. The correct damper materials are
especially important in factories with chemically laden
atmospheres, electroplating shops, battery rooms etc.
When installed and operated properly, the warranty
according to the Swiss Code of Obligations is 2 years.
ateX: Dampers operated in ATEX zones should be
replaced every 10 years for safety reasons.

DRK and RSK basically function without a motor. How-
ever, for special applications, a motor may be fitted
using a special bracket. When fitting motors, always
comply with the maintenance and fitting instructions
of the motor manufacturer. With lift motors, pay spe-
cial attention to power transmission at right angles to
ensure trouble-free operation of the damper. Especially
with drive motors which have high closing speeds, pay
special attention to adequate protection of the move-
ment areas (slats and linkages) to prevent reaching
into the mechanisms. Responsibility lies with the ope-
rator.
ateX: All relevant national and international stan-
dards and regulations for Ex zones must be observed.
In particular, only drive motors, limit switches etc. with
special approval for use in ATEX zones are allowed.
Responsibility lies with the operator.
