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.

HEATING
Motors and electronic accessories must be fitted in
compliance with the relevant regulations of the appro-
priate manufacturers.
Install the motors according to the relevant regula-
tions of the appropriate manufacturers. Comply with
the maintenance and installation instructions of the
corresponding manufacturers.
With lift motors, pay special attention to power trans-
mission at right angles to ensure trouble-free opera-
tion of the damper. Especially with drive motors which
have high closing speeds, pay special attention to
adequate protection of the movement areas (slats and
linkages) to prevent reaching into the mechanisms.
Responsibility lies with the operator.
RGK models close clockwise as standard.
Only use electrical accessories such as monitoring
sensors, limit switches etc. in the areas specified by the
manufacturer and under specified conditions with our
products. This type of component may only be installed
on separate brackets designed for this. It is prohibited
to drill holes or fit bolts or screws in the damper
frames.
ATEX: All relevant national and international stand-
ards and regulations for Ex zones must be observed. In
particular, only drive motors, limit switches, sensors
etc. with special approval for use in ATEX zones are
allowed. Responsibility lies with the operator.
ATEX: All relevant national and international stand-
ards 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
approved 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 fac-
tory that foreign bodies may enter the movement area
of the slats, prevent them by suitable means (filters or
catchment grills). This prevents the slats from sticking
and the possibility of frictional heat developing.

INSTALLATION, OPERATION AND MAINTENANCE INSTRUCTIONS
RGK REGLAIR PRECISION CONTROL DAMPERS
The standard version of the control damper with
electric heating is designed for temperatures down to
-20 °C; special versions are available for temperatures
down to -60 °C.
When installing, make sure no mechanical damage is
made to the heating strip. Do not change the cable
routing to the damper and do not manipulate the
cable brackets. Any change or damage may lead to
partial interruptions in heating or the total failure of
the heating strip. Damaged cables must be replaced by
the manufacturer.
The operator is responsible for wiring, controlling and
monitoring the heating strip and this may only be
carried out by qualified staff. The trace heating must
switch off at +3 °C at the latest so that any conden-
sate can dry off before the outside temperature drops
any further. Do not expose the dampers to the weather
when operated under -20 °C. In this case, the sides of
the dampers must be covered to protect the damper
axles from the effects of the weather.
In addition, a weather-proof louvre with additional
trace heating can be installed on the weather side.
Observe the instructions of the appropriate manufac-
turer for wiring and fusing the heating strip.
ATEX: All relevant national and international stand-
ards and regulations for Ex zones must be observed.
Responsibility lies with the operator. Due to the stricter
safety requirements in ATEX zones, the operator must
inspect the function of the heating cable once a year.
Here we recommend temperature measurements
directly on the heating strip using a tested measuring
instrument.
The specifications below are for verifying the heating
capacity of the heating strip:
Ambient temp. Cable temperature
15 °C bis 1 °C > 30 °C
0 °C bis -20 °C > 20 °C
-21°C bis -50 °C > 10 °C

MAINTENANCE
SPECIAL
INSTRUCTIONS
WARRANTY
Depending on the degree of soiling of the medium,
carry out a dry clean from time to time. In addition
operate the dampers at least four times a year accord-
ing to the plant-specific conditions. This prevents the
slat seals from sticking in closed state. The slide bear-
ings can be blown off using compressed air as required,
although they are basically maintenance-free (lubrica-
tion). Otherwise the RGK models operate mainte-
nance-free.
Only LUCOMA genuine spare parts may be used for all
repair and maintenance work.
ATEX: All relevant national and international stand-
ards 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, elec-
troplating 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.
