1.3. Using the curtain
- The Breeze air curtain is designed to separate the indoor from the outdoor environment by air flow. With
this function, the curtain prevents the indoor air from escaping from the indoor environment to the
outdoor environment when the door, gate, etc. is open... If the curtain is equipped with a water or electric
heat exchanger, the curtain can heat the indoor space in which it is installed when the door is closed.
Temperature control is provided by a wireless room thermostat (included). The curtain can be installed
both in vertical position - by adjusting down, up (depending on the connection possibilities) - and in
horizontal position.
- The curtain is intended primarily for entrances to commercial premises (e.g. shops, restaurants...) and
smaller premises where the installation conditions can be met.
- The curtain is designed for indoor and dry areas with an ambient temperature of +5°C to +40°C. With a
maximum relative humidity (non-condensing) of 80%.
- The operating environment of the curtain must correspond to the curtain ingress protection of IP 20.
- The curtain must not be operated in an environment with explosion or combustion hazards and increased
dustiness. Especially when finishing construction activities, which cause excessive dust, e.g.: grinding
concrete, plasterboard, etc.
- Neither the manufacturer nor the supplier is liable for damage caused by improper use of the curtain.
The user bears the risk.

2. Technical parameters
2.1. Breeze air curtain design
2.1.1. AC axial fan
- Metal fan in Al/Zn socket. Maximum operating temperature of the fan motor is + 60°C, operating
humidity 0-90% non-condensing, degree of protection IP20 according to the selected type of curtain,
motor insulation class F.
2.1.2. Water heat exchanger - BR1-xx-ACV1S-xxx
- Maximum permissible temperature/pressure of the heating medium 120°C / 1,6 MPa. 1-row heat
exchanger consists of an aluminium-copper structure. The water heat exchanger is connected by means
of connection collectors terminated with 1/2" male thread.
2.1.3. Electric bodies – BR1-xx-ACE1S-xxx
- The electrical bodies are designed with PTC cells. This means that the body adapts its power depending
on the heat removal from its surface. The surface temperature of the body is always the same and is
independent of the temperature of the blowing air. This ensures approximately the same Δtregardless of
the set flow rate. Each electrical unit assembly is equipped with safety thermostats (with automatic reset
at 50°C and manual reset at 75°C) to provide protection against overheating, whereby if necessary the
electrical exchanger will be disconnected
2.1.4. Curtain shroud
- The curtain shroud is made of galvanized sheet metal with a thickness of 0.8 mm powder coated with RAL
9003 or RAL 7016 - depending on the selected colour variant of the curtain.
2.1.5. Curtain sidewall / regulation cover
- The sidewall of the curtain is made of galvanized sheet metal with a thickness of 0.8 mm, powder coated
with RAL 9003 or RAL 7016 - depending on the selected colour variant of the curtain. The sidewall located
at the main switch is also a regulation cover (marked with a "lightning” warning sign)
2.1.6. Intake cover / filter
- The intake cover is made of galvanized perforated (expanded) sheet metal powder coated with RAL 9003
or RAL 7016 - depending on the selected colour variant of the curtain. The inlet cover also acts as a coarse
pre-filter to capture large dust particles, thus protecting the internal components of the curtain (heat
exchanger, fans...)

3.1.2. Modification of heating distribution system
- it is advisable to use filters for coarse dirt particles in the heating distribution system to protect the water
exchanger from possible damage from the existing pipes.
3.1.3. Load capacity of the installation site
- the selected installation site must be suitable for the permanent load by the curtain. In case of doubt, the
load-bearing capacity must be checked by a structural engineer or other responsible person.
3.1.4. Minimum mounting clearances
- the minimum distance of the curtain inlet (fan) from the wall or ceiling is 0.2 m.
- the minimum distance between the side of the curtain and the wall is 0.1 m (consider a suitable distance
from the side of the heat exchanger outlets for easy connection)
- If this distance is not observed, the curtain may not work properly and the fans may be damaged or the
noise level of the curtain may be increased. The curtain exhaust must be adjusted so that there is no
draught in the heated space and at the same time the indoor space is completely separated - shielded
from the outdoor space.
3.1.5. Minimum safety distances from combustible substances
- the minimum safety distance from combustibles is at least 0.1 m from the side of the curtain (consider a
suitable distance from the side of the heat exchanger outlets for easy connection) and 0.5 m in the
direction of the curtain inlet. If necessary, adjust the distances according to the site layout.
3.1.6. Curtain operating environment
- The curtain must be placed - operated in covered and dry indoor areas with ambient temperature from
+5°C to +40°C (conditions must be ensured against freezing of water in the heat exchanger - a risk of
damage to the curtain). With a maximum non-condensing relative humidity of 80%.
3.1.7. Curtain alignment
- The curtain must always be aligned - in the spirit level to the relevant operating plane!
3.1.8. Unpacking the curtain - preparation before installation
- Unpack the curtain only from the top (the curtain is shipped in the horizontal position) as follows:
o remove wooden crating
o remove plastic wrappings and tapes

Please, return all unwanted or obsolete products and packaging to the relevant recycling
sites where they will be disposed of professionally. Dispose of the parts of the product
that cannot be utilised to a controlled landfill. Only a product recycled in this way can be
reused properly and returned to the utility.
3.2. Vertical installation
- The curtain must sit on a clean, level, consistent and solid surface.
- The correct curtain position is at least 100 mm higher than the height of the curtain itself.
- When installed vertically, the curtain cannot be chained
- The curtain exhaust must be placed as close as possible to the shielded opening
- Pay particular attention that the inlet and exhaust of the curtain is not obstructed by any obstacle and
that it does not restrict the operation of the technical equipment of the building (security system, fire
protection system...etc.)
3.2.1. Fixing the curtain base to the floor
- Fix the curtain to the floor using the "BREEZE-BASE" base (to be ordered separately as an accessory. The
base has the same layout dimensions as the curtain.
- Determine the location (floor, ceiling) of the curtain connection to the main electrical supply and the
piping (depending on the version chosen) within the layout possibilities where the curtain is installed.
3.2.1.1. Top curtain connection - from the ceiling - base (curtain regulation at the top - at the ceiling)
a) Place the base at the opening you want to shield as follows:
o The edge of the curtain base closer to the wall must be in line with the frame of the opening to
be curtained at a minimum distance from the wall (see 3.1.4. and 3.1.5.)
o Rotate the base outwards by 10° - rough adjustment - important for future correct operation
of the curtain
b) Mark the centre of the drilled hole in the four grooves for anchoring to the floor. The centre of the
drilled hole must be at the extreme positions of the anchor grooves, to allow for the possibility of a
higher pre-blow of the curtain (even more outward rotation of the curtain). The base installed in this
way allows a pre-blow adjustment of ±10°, i.e. the curtain can be rotated from 10° to 30°.
c) Select the appropriate anchoring material and tools according to the material and type of floor. The
anchoring material is not part of the supply.
d) The diameter of the anchoring material (anchors, screws for dowels) must be 8 mm (hole dia. in
the base 10 mm). Washers must be placed under the head and nut of the anchor bolt to better
distribute the weight of the curtain.

e) Mount the base to the floor so that the anchor bolts are at the extreme positions of the anchor slots
for a possibility of later increasing of the curtain pre-blow. The curtain should be automatically
rotated outwards by 10°. Make the final rotation of the curtain pre-blow according to local
conditions.
f) Re-tighten the base to the floor.
3.2.1.2. Bottom curtain connection - from the floor - base (curtain regulation at the bottom - at the
floor)
- The base mounting procedure is the same as for the top connection (see Chapter 3.2.1.1.)
3.2.2. Placing the curtain in the working position
3.2.2.1. Top curtain connection - from the ceiling (curtain regulation at the top - at the ceiling)
a) Place - set the unpacked curtain in the working position
b) Slide the curtain onto the base guide rails
c) Secure the curtain to the base with 6 self-tapping screws Ø3.5x9.5 (included in the "BREEZE-BASE"
base package) against falling.

3.3. Vertical installation - chained curtains
- Vertical chaining of curtains is allowed up to a maximum height of 4 m
- By chaining - connecting the curtains to each other, it is possible to create an optimum assembly for the
correct shielding of the required opening based on its dimensions.
- The correct height of the chained assembly must be at least 100 mm longer than the actual height of the
shielded opening.
- The curtains are chained using the "BREEZE-CONNECT" connecting part (to be ordered as an accessory).
3.3.1. Installation of chained curtains
- Vertically chained curtains shall have the orientation of the media facing away from each other to
ensure access to the media after the curtains are installed.

ORIENTATION OF THE CONNECTING PERIPHERY
- Install the curtain base for the bottom connection according to Chapter 3.2.1.2.
- If you want to control the chained curtains with 1 wireless thermostat, perform the pairing according to
Chapter 4.2.4.
- Install the bottom curtain according to Chapter 3.2.2.2
- Install the "BREEZE-CONNECT" connecting piece onto the top of the anchored curtain so that ½ of the
connecting piece protrudes above the anchored curtain. Use 4x self-tapping screws 3.5x9.5 (included in
the connecting piece package) to mount the connecting piece.
- Lift the curtain to be connected to the lower anchored curtain by appropriate lifting equipment.

- Make sure that the curtain is oriented within the correct position range of the connecting periphery to
the supply media - top curtain connection, see Chapter 3.2.2.1.
- Ensure that all safety principles arising from the handling of the curtain are observed to prevent
damage to property and personal health.
Secure the top curtain with 4x 3.5x9.5 self-tapping screws (included in the connecting piece package).
3.4. Side anchoring of the chained assembly
- When chaining curtains, it is necessary to anchor each successive curtain from the side to maintain the
stability of the whole assembly.
- The side anchorage must always be made at the top curtain, at the curtain joint and at the highest point
of the chain assembly.
- Use the "BREEZE-HINGE" accessory set for side anchorage of the assembly
o Always install the "BREEZE-HINGE" set (included in the curtain package) to the top curtain in all 4
anchor points.
- Choose the appropriate method and fasteners for anchoring the curtain according to the situation at the
installation site
- Make sure that all bolted connections are tightened correctly so that the installed curtain cannot
become loose and fall down, causing damage to property and health.
- For better securing of the bolted connections, we recommend to use a lock nut M6 (not included in the
delivery of BREEZE-HINGE accessories).
3.5. Vertical installation - increasing the shielding effect
- To increase the shielding effect, the curtain can be installed on both sides of the opening
- The curtains are installed the same way as described in Chapter 3.3.

3.6. Horizontal installation
- The surface (e.g.: wall) and auxiliary structures that are needed to anchor the curtain must have an
adequate load capacity based on the weight of the selected curtain type. Anchoring material and
auxiliary structures are not provided by the supplier. Provided by the user according to local conditions.
See Chapter 3.4.1 for installation examples.
- For the proper function of the curtain (shielding the opening), the curtain must be at least 100 mm longer
on each side than the width of the opening to be shielded. If the curtain width is greater than or equal to
the curtain length another curtain should be added
3.6.1. Selecting the installation location
- Select the location for the installation of the curtain; the exhaust of the curtain must be aligned with the
frame of the opening to be shielded at a minimum distance from the wall (see 3.1.4. and 3.1.5.). If this is
not possible, the general rule for correct placement and subsequent rotation of the curtain (pre-blow
setting) is that the corner of the curtain exhaust must always be tangent to the shielded opening. For
further explanation, see Chapter 3.7.
3.6.2. Auxiliary anchoring structures
- Prepare suitable auxiliary anchoring structures (brackets, threaded rods, etc.) according to the weight of
the curtain, the surface to be anchored to, and the chosen method of mounting (ceiling, wall, etc.).
Breeze air curtain weight table:
- Select the length of the threaded rods you use for hanging so that they allow you the standard curtain tilt
by approx. 10° towards the shielded opening (basic pre-blow) and then to increase the pre-blow according
to the local conditions at the installation site.
- The length difference of the threaded rods for the 10° basic pre-blow adjustment is approx. 50 mm.
- The spacing of the anchor threaded rods on which the curtain is to be hung should comply with 2.2.
3.6.3. Installation of the curtain in a horizontal position
- For the correct determination of the curtain angle, it must be observed that the corner of the curtain
exhaust is always tangent to the shielded opening.
- The curtain can be hung with the use of:
o M6 nuts located in the sidewall of the curtain.
- RECOMMENDED - BREEZE-HINGE accessory set - single hinges for attachment to the press-fit M6 nuts
located in the sidewall of the curtain

3.6.4. Examples of hanging the curtain - horizontal installation
3.6.5. Mounting-hanging the curtain in the working position
- Screw the mounting lugs with external thread M6 (part of the "BREEZE-HINGE” accessory - installation kit)
into the 4 prepared M6 nuts located on the sides of the curtain
- Install the mounting lugs with M6 female thread (part of the "BREEZE-HINGE" installation kit) on the
prepared threaded rods (in the ceiling or in the brackets - on the wall).
- Make sure that all bolted connections are tightened correctly so that the installed curtain cannot
become loose and fall down, causing damage to property and health.
- For better securing of the bolted connections, we recommend to use a lock nut M6 (not included in the
delivery of BREEZE-HINGE accessories).
- Lift the partially unpacked curtain according to 3.5.1. with suitable handling equipment (e.g.: forklift truck)
to the prepared installation location. Partial packaging (pallet, protective polystyrene) serves as a
protection against damage - scratching of the product.
- When handling the curtain, take into account the weight of the curtain and ensure that all safety
precautions are taken to avoid damage to property and personal health.
