1. General information
1.1. Introduction
- This document "Installation and Operating Manual" is intended for the Wind air curtain (hereinafter the
"curtain"), which is used to separate the interior from the external environment by a stream of air and for
hot-air heating of the required space. Detailed familiarisation with this document is important for the
correct and safe installation and functioning of the curtain. Failure to follow the conditions in this document
may result in malfunction of the unit.
- The curtain may only be installed and connected by a trained person with the appropriate authorization
to connect electrical equipment, which has available suitable tools and means. During the assembly, it is
necessary to observe all the instructions and recommendations in this manual.
- For the correct operation and long-term service life of the unit, it is necessary to prevent access to
unauthorised persons and to train operators according to this document and applicable legislative
regulations.
- The documentation must always be available at the place of installation for any service intervention. It is
forbidden to interfere in any way with the internal connection of the curtain, which does not correspond to
the instructions given in this manual. Due to the continuous development of our products, we reserve the
right to change this manual without prior notice.
1.2. Use of the unit
- The Wind air curtain is designed to separate the interior from the environment by a stream of air. This
prevents the internal air from leaking out of the internal environment to the external environment when
the doors, gates, etc...are open. Other function of the curtain when the doors or gates are closed is to heat
the internal space by hot-air heating. When purchasing accessories – filter, the curtain also serves to filter
the air in the inner environment.
- The curtain is intended mainly for entrances to industrial halls, warehouses, sports facilities, workshops,
smaller facilities and commercial premises.
- The curtain is designed for indoor covered and dry areas with ambient temperatures between 5°C and
+40°C.
- The curtain may also be used for environments with a higher non-condensing humidity corresponding to
the protection class IP54 and IP44 according to EN 60529, depending on the type of curtain. However, the
maximum allowed humidity is 80%. The curtain may also be used in corrosive environment C2 according to
EN ISO 9223. The curtain must not be operated in an environment with the risk of explosion and increased
dustiness.
- Neither the manufacturer nor the supplier is liable for damage caused by improper use of the curtain. The
risk is borne by the user alone.
- The curtain must not be operated during finishing construction activities, especially during activities that
create excessive dustiness, e.g. by grinding concrete, plasterboard, etc...
1.3. Transport, inspection of delivery and storage
- Before starting the installation and before unpacking the unit from the box, it is necessary to check for any
traces of damage on the packaging. In case of damage to the packaging, please contact your carrier.
- Check if the product ordered by you is in agreement. After unpacking, check that the unit and other
components are intact. Please report any non-conformity with the order to the supplier immediately.
If an order complaint is not made immediately after delivery, it will not be taken into account later.
- If you do not install the unit immediately after purchase, it must be stored in an indoor, non-
condensing environment at temperatures in the range of 5 to 40°C. If the product has been
transported at temperatures below 5°C, it must be stored after unpacking for at least 2 hours in the
working environment where it will be installed.
- Use adequate tools to prevent damage to the goods and to avoid health and safety risks of persons.

2. Technical parameters
2.1. WIND air curtain design
2.1.1. AXIAL EC FANS
The maximum operating temperature of the fan motor is + 60°C, operating humidity 0-90% non-condensing,
protection class IP54 and IP44 according to the selected curtain type, and the motor insulation class B. The fan and
its board are treated with powder coating RAL 9005.
2.1.2. WATER EXCHANGER
Maximum permissible temperature/pressure of heating medium 120°C / 1.6MPa. The exchanger consists of
an aluminium - copper structure. Water exchanger is connected by connectors with mail thread 1". The
exchanger is equipped with a venting valve on both collectors.
2.1.3. CURTAIN CASING
The sheet metal casing of the curtain consists of two parts. The rear part towards the fan is in RAL 9005
colour. The front part towards the exhaust lamellas is in RAL 7016 colour.
2.1.4. EXHAUST LAMELLAS
The exhaust lamellas are designed from aluminum profiles, which are provided against corrosion and
mechanical damage by "anodizing" (artificial corundum). They are not used to deflect the air stream. The air
flow redirection is tackled in Chapter 3.7.

3. Installation – installation of air curtains in the working position
3.1. General information, recommendations and safety during installation of the Wind air curtain
3.1.1. Electrical safety when installing the curtain
- Before starting any assembly works, it is necessary to switch off the power supply to the prepared
electrical installation for subsequent activation of the unit. During installation, the switch must be
secured against being switched on again.
3.1.2. Modification of existing heating distribution systems
- It is appropriate to use filters for rough impurities in the heating systems to protect the water exchanger
from possible damage from the existing distribution systems.
3.1.3. Load bearing capacity of the assembly site
- The selected assembly site must be suitable for the permanent load by the curtain. In case of doubt, the
load capacity of the wall/walls must be verified by a structural engineer or other responsible person.
3.1.4. Minimum assembly distances
- The minimum intake distance (fan) of the curtain from the wall/ceiling is 0.3 m.
- The minimum distance between the side of the curtain and the wall is 0.1 m (assess a suitable distance
from the side of the exchanger outlets to allow easy connection).

- If this distance is not observed, the curtain may not work properly and the fans may be damaged or the
noise of the unit may increase. The curtain exhaust must be set in such direction that there is no draft in
the heated space, and, at the same time, for the best separation of spaces – to shield the inner space from
the external influence. The air flow exiting the exhaust grid must not be directed directly to walls, beams,
shelves, machines, etc.
3.1.5. Minimum safety distance from flammable substances
- The minimum safety distance from flammable substances is at least 0.1 m from the side of the curtain
(assess a suitable distance from the outlet of the exchangers due to easy connection) and 0.5 m in the
direction of suction of the curtain. Adjust the distances according to the layout of the space.
3.1.6. Operation environment of the curtain
- The curtain must be located / operated in an inner dry space with temperatures range from 5°C to +40°C
(the conditions must avoid water freezing in the exchanger – there is a risk of damage to the curtain) and
non-condensing humidity corresponding to protection class IP 54 and IP 44, according to the selected type
of curtain.
3.1.7. Levelling of the curtain
- The curtain must be always levelled – with spirit level in the appropriate plane in which it is operated!
3.2. Ceiling installations
- The curtain must stand on a flat, coherent and solid surface.
- The correct height of the curtain must be at least 100 mm longer than the actual height of the curtained
hole. If the height of the opening is greater than or equal to the height of the curtain, you must attach an
additional curtain, see Point 3.3.
3.2.1. Positioning the curtain in the working position
- Place the unpacked curtain in its working position.
- Place it close to the hole that should be curtained in such a way that:
o The edge of the exhaust curtain closer to the wall must be flush with the door frame hole, at a
minimum distance from the wall (see paragraphs 3.1.4. and 3.1.5.)
o Turn the curtain at 10° with the exhaust pointing out.
Curtain pre-blow setting - important for correct operation of the curtain
3.2.2. Fixing the curtain to the floor
- The curtain is fixed to the floor using the "WIND-HOLDER" (must be ordered as accessories).
- Screw the holder to the curtain with 6 screws M6x20 (a part of the packing of the “WIND-HOLDER”).
- Mark the center of the drilled holes in the four grooves for anchoring to the floor. The centre of the drilled
holes must be in the end positions of the anchoring grooves, for the possibility of increasing the curtain pre-
blow (even greater turning of the curtain out). The holder installed in this way allows an increase of the pre-
blow by up to 20°, i.e. the curtain may be rotated from 10° to 30°.
- Select suitable anchoring material and tools according to the floor material and type. Anchoring material is
not part of the delivery.

POSSIBILITY OF ROTATION UP TO 20 °
- The diameter of the anchoring material (clamps, bolts into dowels) must be 10 mm. A washer shall be
placed under the head of the anchoring screws/nuts to better distribute the curtain weight.
- Screw the holder into the floor in such a way that the anchoring screws are in the end positions of the
anchoring grooves for the subsequent possibility of increasing the pre-blow of the curtain. The curtain
should be automatically rotated 10° outwards. Final fine-tuning – the curtain rotation is dealt with in point
3.7.
- Tighten the holder to the floor.
3.3. Vertical installation - curtain chaining
- Chaining – connecting the curtains to one another makes it possible to create an ideal assembly for proper
clearance of the required opening according to its dimensions.
- The correct height of the chained assembly must be at least by 100 mm longer than the actual height of the
construction opening.
- The curtains are chained on each other using the "WIND-CONNECT" connecting piece (it is necessary to order
the pieces as accessories).
3.3.1. Chained curtain mounting
- Install the "WIND-CONNECT" connection piece onto the top of the anchored curtain, so that 1/2 of the
connection piece projects over the anchored curtain. Use 6 screws M6x20 (part of the connecting piece
packing) to install the connection part.
- Lift up the curtain to be connected to the lower anchored curtain with appropriate lifting devices.
- Ensure compliance with all safety principles resulting from handling the curtain to prevent any damage to
the property and health of persons.
- Insert the curtain into the prepared /mounted connection piece and secure with 6 screws M6x20 (part of the
fitting package).
