ATEX
RGK dampers are only approved in specific designs and with appropriate iden-
tification for Zones 1, 21 or 2, 22 according to Atex Directive 2014/34/EU.
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 addition-
al equipment are installed in compliance with zoning requirements.
Shipment
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 dampers, use at least
four points at the corner angles as suspension points. Do
not use individual slats under any circumstances as foot-
holds during installation. Report any damage, e.g. defor-
mation of slats, dents, impacts or warping of the C-profile
frame etc. immediately to the supplier or manufacturer.
This may impair 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.
Installation
Mount the dampers warp-free, tension-free, on a flat sur-
face and without any angular errors in the damper frame.
When mounting, use the 4 corner holes provided as stand-
ard. 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 com-
plete, check the angle of the damper frame. It must be
exactly 90°. Correct any deviations immediately. In addi-
tion check the free movement of the slats, linkage and
gear wheels. Avoid as far as possible any reduction in free-
dom of movement on customer premises when installing
insulation materials, installation ducts, auxiliary structures
etc. If this is not observed, it can lead to considerable dis-
ruptions 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 application that
additional bolts or reinforcements are affixed with damp-
ers larger than 1000×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 installation
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 standards
and regulations for Ex zones must be observed. On damp-
ers with ATEX functionality in particular, the damper hous-
ing 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 com-
ponents (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 in-
terior of the dampers. This could lead to damage or dis-
turb damper operation. If there is a risk at the factory that

Installation, Operation and Maintenance Instructions

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, motors and electronic
accessories
Motors and electronic accessories must be fitted in com-
pliance with the relevant regulations of the appropriate
manufacturers.
Install the motors according to the relevant regulations of
the appropriate manufacturers. Comply with the mainte-
nance and installation instructions of the corresponding
manufacturers.
With lift motors, pay special attention to power transmis-
sion 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 protec -
tion 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 manufac-
turer 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 standards
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.
Dampers with electric heating
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 rout-
ing to the damper and do not manipulate the cable brack-
ets. Any change or damage may lead to partial interrup-
tions 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 condensate can dry off be-
fore 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 cov-
ered 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 manufacturer for wiring
and fusing the heating strip.
ATEX: All relevant national and international standards
and regulations for Ex zones must be observed. Responsibility
lies with the operator. Due to the stricter safety require-
ments in ATEX zones, the operator must inspect the func-
tion of the heating cable once a year. Here we recom-
mend temperature measurements directly on the heating
strip using a tested measuring instrument.
The specifications below are for verifying the heating ca-
pacity of the heating strip:
Ambient temperature Cable temperature
15 °C bis 1 °C > 30 °C
0 °C bis -20 °C > 20 °C
-21 °C bis -50 °C > 10 °C
Maintenance
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 according to the
plant-specific conditions. This prevents the slat seals from
sticking in closed state. The slide bearings can be blown
off using compressed air as required, although they are
basically maintenance-free (lubrication). Otherwise the
RGK models operate maintenance-free.
Only LUCOMA genuine spare parts may be used for all
repair and maintenance work.
ATEX: All relevant national and international standards
and regulations for Ex zones must be observed.
Special instructions
Before using LUCOMA dampers in areas with increased
requirements, report the prevailing conditions to the man-
ufacturer so that the correct damper materials can be
selected.
The correct damper materials are especially important in
factories with chemically laden atmospheres, electroplat-
ing shops, battery rooms etc.
Warranty
When installed and operated properly, the warranty ac-
cording to the Swiss Code of Obligations is 2 years.
ATEX: Dampers operated in ATEX zones should be re-
placed every 10 years for safety reasons.
