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.
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.
1.4. Transport, Delivery Control, and Storage
1.4.1. Transport
- During transport, keep the product in the position indicated by the symbol on the packaging.
- The packaging must not be loaded with a weight higher than that permitted by the manufacturer.
- The packaging must not be exposed to environmental influences.
- The transport air temperature must range between -25 to 55 °C,
- The transport relative humidity must range between 10 % and 90 % non-condensing.
- Use adequate tools to prevent damage to the goods and threats to the health and safety of persons.
- In the case of further transport without original packaging or with changed original packaging, it must be
ensured that the equipment is optimally secured and protected against damage.
1.4.2. Delivery Inspection
- Before starting the installation and before unpacking the product 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.

other components are in order. Please, report any discrepancy with the order to the supplier
immediately. If an order complaint is not made immediately after delivery, it will not be accepted later.
1.4.3. Storage
- If you do not plan to install the unit immediately after purchase, it must be stored in an indoor, non-
condensing environment at temperatures ranging between 5 to 40°C. If the product is transported at
temperatures below 0°C, it must be put into the working environment where it will be installed for at
least 2 hours after unpacking.

1.6. Before Commencing the Installation
- Before commencing the installation, we recommend that you attach the serial plate (by default, supplied
with the package) to the operating documentation (e.g.: equipment operations log, etc.), which is
subsequently kept for a later maintenance records and servicing.
- Before starting any installation or maintenance work, the power must be switched off and
the main switch secured against being switched on again.
- Verify that the electrical supply meets the requirements for the curtain power supply (voltage, current,
etc.) listed on the unit's name plate, see Chapter 3.10.
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...)
