I. GENERAL
Description
Damper characteristics
■Tested in accordance with EN 1366-1, Type B for 120 minutes.
■External Casing leakage class B, Internal leakage min. class 3 acc. to EN 1751
■Please Note: The damper will require a Flamebar BW11 or BW18 coating to achieve fire resistance to BS EN 1366-1.
Working conditions
■Exact damper function is provided under the following conditions
■maximum air velocity 12 m/s
■underpressure max. -1500 Pa or overpressure max. 500 Pa
■Dampers are installed with the horizontal or vertical axis of the blades.
■Dampers are suitable for systems without abrasive, chemical and adhesive particles.
■Dampers are designed for macroclimatic areas with mild climate according to EN IEC 60 721-3-3 ed.2., class 3K22.
■Temperature in the place of installation is permitted to range from -20°C to +50°C.
The Mandik VCDM is a volume control damper suitable for
use at high temperatures.
The VCDM can be used to control and balance the airflow
through connecting ductwork and has been tested for high
temperature applications.
The VCDM is available in sizes from 200x200 to 1200x1200 as
a single unit.
The damper comes equipped with a manual handle which can
be sent incrementally to set the position of the blades.
An extended spindle allows for the damper to be insulated to
meet the requirements of the ductwork.

III. MATERIAL, FINISHING
Material
■Damper casing and damper blade are made of galvanized sheet metal without any other surface finish.
■Fasteners are galvanized.
■According to the customer's requirements, damper can be made of stainless material.
Specifications for stainless-steel models – classification of stainless steel:
■Class A2 – Food-grade stainless steel (AISI 304 – EN 17240)
■Class A4 – Chemistry-grade stainless steel (AISI 316, 316L – EN 17346, 17349)
The respective stainless steel is the material for all components present or accessing the damper interior; components
outside the damper body are typically from galvanised sheet metal.
The following components, including the fasteners, are made from stainless steel at all times:
■Damper body and all components permanently attached
■Blade´s holders, including pins, metal parts of blade
Plastic, rubber and silicon components, sealants, foaming bands, glass-ceramic seals, housings, brass bearings of the blade,
actuators, and end switches are identical for all material variants of the dampers.
Some fasteners and components are available in one class of stainless steel; the type will be used in all stainless-steel
variants.
Any other requirements for the design shall be considered atypical and shall be addressed on an individual basis.
IV. INSPECTION, TESTING
■The appliance is constructed and preset by the manufacturer, its operation is dependent on proper installation and
adjustment.
V. TRANSPORTATION AND STORAGE
Logistic terms
■Dampers are delivered on a pallets. As standard, the
dampers are wrapped in plastic foil for protection during
transport and must not be used for long-term storage of
the equipment . Changes in temperature during transport
may cause condensation of water vapour inside the
packaging and thereby condisitions may arise inside the
packaging that are suitable for corrosion of materials used
in the equipment (e.g. white corrosion on zinc-coated
items or mould on calcium silicate). Therefore, it is necess-
ary to remove the transport packaging immediately after
unloading to allow air to circulate around the product.
■The equipment must be stored in clean, dry, well
ventilated and dust-free environment out of direct sun-
light. ensuring protection against moisture and extremes
of temperatures (minumum temperature +5°C) the equip-
ment must be protected against mechanical and accid-
ental damage prior to installation.
■Another required packaging system should be approved
and agreed by manufacturer. Packaging material is not
returnable in case that another packaging system
(material) is required and used and it is not included into
final price of damper.
■For unloading and further manipulation with the damper
is necessary to use appropriate tooling (forklifts) due to
damper weight. Dampers are fragile.
■Dampers are transported by box freight vehicles without
direct weather impact, there must not occur any shocks
and ambient temperature must not exceed +50°C.
Dampers must be protected against impact when
transported and manipulated. During transportation, the
damper blade must be in the "CLOSED" position.
■Dampers are stored indoor in environment without any
aggressive vapours, gases or dust. Indoor temperature
must be in the range from -30°C to +50°C and maximum
relative humidity 95% (avoid condensation on the damper
body). Dampers must be protected against impact when
transported and manipulated.

VI. ASSEMBLY, ATTENDANCE AND MAINTENANCE
Assembly
■Assembly, maintenance and damper function check can
be done only by qualified and trained person, i.e.
“AUTHORIZED PERSON” according to the manufacturer
documentation. All works done on the fire dampers must
be done according international and local norms and laws.
■All effective safety standards and directives must be
observed during damper assembly.
Entry into service and revisions
■Before entering the dampers into operation after
assembly and after sequential revisions, checks and
functionality tests. After entering into operation, these
revisions must be done according to requirement set by
national regulations.
■In case that dampers are found unable to serve for their
function for any cause, it must be clearly marked. The
operator is obliged to ensure that the damper is put into
condition in which it is ready for function.
Spare parts
■Spare parts are supplied only on basis of an order.
