1 Safety
1.1 Correct use
Type AKK shut-off dampers are used to shut off the
volume flow rate in ventilation systems within closed
rooms.
In kitchen exhaust air systems, the shut-off damper
may only be used if it is ensured that the extract air
is cleaned as well as possible by highly effective aerosol
separators, see VDI 2052.
Type AKK shut-off dampers can especially be used in
ventilation systems with chemical contamination (e.g.
point extraction or extract air from laboratory fume cup-
boards).
Incorrect use
WARNING!
Danger of injury or risk of damage to property
due to incorrect use!
Misuse of the unit can lead to dangerous situations.
Never use the unit:
– in areas with potentially explosive atmospheres
(EX)
– in aircraft
– outdoors without sufficient protection against the
effects of weather
– In wet areas
– for areas of application that are not described in
this manual
Modifying the unit or using replacement parts that have
not been approved by TROX is not permitted.
1.2 Dangers when handling the unit
The unit is a state-of-the-art product and meets current
safety requirements. Residual risks cannot be excluded,
however, and you should proceed with caution. This
section describes the residual risks that have been iden-
tified in a risk assessment.
Always follow the safety notes in this manual to reduce
health hazards and prevent any hazardous situations.
1.2.1 Electric shock hazards
Electric current
DANGER!
Danger of death due to electric current!
Contact with live parts poses an immediate danger
to life due to electric shock. Damaged insulation or
damaged parts are a life threatening hazard.
– Work on the electrical system must only be car-
ried out by skilled qualified electricians.
– If the insulation is damaged, disconnect the
power supply immediately and have the insula-
tion repaired.
– Before you start working on electric systems and
equipment, switch off the supply voltage and
secure it against being switched on accidentally.
Comply with the following safety rules:
– Switch off the supply voltage.
– Secure it against being switched on acciden-
tally.
– Ensure that no voltage is present.
– Connect to the earth; short circuit connection.
– Do not bypass or disable any circuit breakers. Be
sure to maintain the correct current rating when
you replace a circuit breaker.
– Ensure that live parts do not come into contact
with moisture. Moisture can cause a short circuit.
1.2.2 Dangers due to stored energy
DANGER!
Risk of injury due to stored energy.
Pneumatic actuators are pressurised and can cause
the damper to move abruptly:
– Only qualified personnel may work on the pneu-
matic actuator.
– Switch off the compressed-air supply before
working on any pneumatic equipment.
– After switching off the compressed-air supply,
trigger the actuator to discharge the stored
energy.

1.3 Qualified staff
WARNING!
Danger of injury due to insufficiently qualified
individuals!
Incorrect use may cause considerable injury or
damage to property.
– Only specialist personnel must carry out work.
The following degrees of qualification are required for
the work described in the operating manual:
Skilled qualified electrician
Skilled qualified electricians are individuals who have
sufficient professional or technical training, knowledge
and actual experience to enable them to work on elec-
trical systems, understand any potential hazards related
to the work under consideration, and recognise and
avoid any risks involved.
1.4 Personal protective equipment
Personal protective equipment is equipment that pro-
tects the user against health or safety risks at work.
Personal protective equipment must be worn for var-
ious types of work; the protective equipment required
is listed in this manual together with the description of
each type of work.
Description of personal protective equipment
Safety shoes
Safety shoes protect the feet against crushing, falling
parts, and slipping on slippery ground.
1.5 Repair and replacement parts
The devices must be repaired by qualified personnel
using genuine replacement parts only. This particularly
applies to work on the electrical equipment. For safety
reasons, defective devices should therefore be repaired
by the TROX Technical Service, linktarget [Kundendienst Betrieb]
doesn't exist but @y.link.required='true'.
1.6 General safety measures

2.2 Functional description
Type AKK shut-off dampers are intended to be used for
the low-leakage shut-off of volume flows in ventilation
systems with circular ducts. The damper is used to iso-
late parts of the ventilation system.
A duct section is closed off by means of a damper blade
via manual actuation (standard construction) or optional
actuators with electric or pneumatic signalling. Actua-
tors are available in various constructions with regard
to power supply, safe position (in a de-energised or
depressurised condition) and auxiliary switches for the
electrical monitoring of the damper blade position.
The actuator of a damper blade must be controlled by a
customer-side circuit and then moves the damper blade
to the OPEN or CLOSED position.
2.3 Display of the damper blade posi-
tion
The damper blade position corresponds to the mark on
the shaft and is thus recognisable from the outside.

2.4.2 CE marking / declaration of incorpo-
ration
The AKK unit complies with the Machinery Directive
2006/42/EC as partly completed machinery, as it does
not fulfil an independent function on its own. A CE mark
and a Declaration of Conformity are therefore not per-
mitted in accordance with the Machinery Directive.
In accordance with the Machinery Directive, partly com-
pleted machinery obtains a Declaration of Incorporation.
This Declaration of Incorporation confirms that the basic
safety aspects of the Machinery Directive and any other
directives are observed.
The Declaration of Incorporation can be accessed via
the QR code on the rating plate. You can download the
document on the Internet at www.troxtechnik.com .

3.1 General installation information
Select the installation location such that the unit,
inspection accesses and the actuator remain acces-
sible for the following work:
– Wiring
– Adjustment work (service socket if necessary)
– Inspection and maintenance, e.g. for replacing
the actuator.
For information on space requirements, see product
data sheets.
Installation in extract air systems in commercial
kitchens is only permitted if the extract air has
already been cleaned with aerosol separators, see
VDI 2052.
3.1.1 Installation of sound attenuators
Circular silencers are usually installed between the
shut-off damper and the room. The circular silencer, e.g.
CAK (same nominal size) can be installed adjacent to or
behind a shut-off damper.
3.2 Fixing/suspension
General installation information
When designing and constructing ventilation and air
conditioning systems, take into account the require-
ments of VDI 6022, in particular:
– Hygienic, clean installation of all components
and their air distribution surfaces.
– Planning inspection/cleaning openings in the
ducting system.
– Avoidance of leaks.
Affix the unit proficiently and only to load-bearing
components.
Load suspension systems only with the weight of
the unit. Adjacent components and connecting ducts
must be supported separately.
Only use approved and sufficiently dimensioned
suspensions for fixing. Secure screw connections
against self-loosening, e.g., by locking them. Fixing
material is not included in the supply package.
Only use the shortest possible drilling screws for
fixing into place; these screws must not be screwed
into the movement and sealing area of the damper
blade.

3.3 Connecting the air duct
When connecting the ducting, the customer must
ensure that the connection points are installed as air-
tight as possible in order to avoid negative influences
from leakages such as air volume deviations, power
consumption, etc. Unless otherwise stated, the con-
necting material is not included in the supply package.
In the case of one-sided connection of the ductwork,
intervention in the damper blade is to be prevented by
suitable measures (for example, grilles).
Before connecting the ducting:
Check the inside of the unit for damage and loose
parts.
Remove any contamination from the ducting.

5 Commissioning and opera-
tion
5.1 Requirement for commissioning
Contamination, e.g. dust, can adversely affect the func-
tionality of the shut-off damper.
Therefore, the ventilation and air conditioning system
and its components may not be put into operation for
the first time until the rooms connected to the ventila-
tion system have been cleaned of any contamination
resulting from construction work. Contamination of the
ventilation system by construction dust and sucked-in
dirt particles must be eliminated. In the case of systems
that are heavily contaminated due to construction activ-
ities, the system may need to be cleaned before com-
missioning.
5.2 Commissioning
Code of good practice for commissioning
Commissioning is governed by the standard "DIN
EN 12599 Testing and measuring procedures for the
transfer of installed ventilation and air conditioning
systems", and, if applicable, contractually agreed
services between HVAC contractors, system owners
and installation engineers. The standard describes
the essential commissioning steps of the complete-
ness check, function check, function measurement
as well as report generation and handover.
5.2.1 Installation and connection
Once the electrical connections have been correctly
installed and made, the shut-off damper is ready for
operation.
5.2.2 Settings by others
Setting of the auxiliary switch
For actuators with auxiliary switches, set the switching
points.
Special version
Bus-compatible actuators may require integration into
the building's network infrastructure to be performed
by others (network commissioning, e.g. setting the sub-
scriber address and communication parameters). Man-
ufacturer-specific tools such as adjustment devices or
software packages and associated interface adapters
may be required for this.
5.2.3 Functional test
Prerequisites for the functional test
Electrical or pneumatic connections have been cor-
rectly installed and tested.
Ventilation and air conditioning system is in opera-
tion (fans running).
Supply voltage or the compressed air supply is
switched on.
1. Check damper blade positions:
Door open
Door closed
Intermediate position (only for variable actua-
tors)
2. Check the auxiliary switch positions.
5.3 Operation
Once commissioning has been completed, the shut-off
damper will operate in a self-powered manner and
require no intervention from the system owner.
In case of a malfunction, decommission the shut-off
damper and have it repaired before commissioning it
again.
