Government Decree No. 481/2012 Coll. (Regulation of the European Parliament and of the Council No. 2014/35/EU,
Regulation of the European Parliament and of the Council No. 2011/65/EU).
Government Decree on restriction the use of some hazardous materials found in electrical and electronic products.
Observe generally applicable national provisions and other related regulations. Unplug the curtain from mains before any service
intervention. Connection and earthing of the electric device or components thereof must be in line with laws applicable in the
country of use. Only qualified staff may carry out any electric service works.
Observe applicable laws, in particular:
on safety of electric and thermal appliances,
on central heat distribution systems,
on fire safety,
do never exceed working pressure and temperature specified in the production label.
Follow standards and rules applicable in the country of use, in particular the fire safety of appliances and heat sources, and the
fire technical properties of materials - flammability levels. Place the curtain 150mm from B, C1, C2 level flammable materials, and
400mm and 1000mm for C3 level easily flammable materials in the radiation direction (air flow from the curtain).
4. Basic information about the curtain and its use
An air curtain is a device, which produces a natural air barrier against penetration of cold air into heat environment (in summer,
it operates as a protection against penetration of hot summer air to the spaces being either cooled or air conditioned). These
devices are suitable for basic and non-aggressive environment. The permitted temperature range in the space is 5–40 °C.
For the curtaining purposes, either circulation air of the environment temperature or the circulation air heated by hot-water or
electric heater may be used. The use of the device can save high cooling costs in the air conditioned spaces. Full performance of
the curtain may be provided only when maintenance is regular and proper. All controls are accessible and well maintained.
Technical conditions for curtain operation:
max. media working temperature 90°C/pressure 1.6MPa – unless specified otherwise,
hot water working voltage –230V/50Hz, electric heater curtain working voltage - 400V/50Hz,
max. surrounding temperature 40 °C,
IP rating of hot water curtain - IP 20/IP rating of electric heater curtain - IP 20,
the curtain is intended for basic and non-aggressive environment,
minimum pressure difference 23kPa must be provided for use of a 2W valve (applies only to a
pressure-independent valve).
