PURPOSE
Plastic wind-powered turbine vent for roofs
Turbine vent a.k.a. nanodeflector Dalap Dorn is an aerodynamic device for natural ventilation with the aid of wind and
is installed at the output of ventilation ducks. The device is designed for commercial, industrial and residential
buildings, cells, garage premises and other smaller enclosed spaces without requirements for total air purification,
specific air exchange or where it is possible to range the air exchange depending on weather conditions.
Nanodeflector Dalap Dorn uses wind energy providing air rarefaction in a ventilation shaft and increases air exhaust
intensity. Thanks to its spherical shape, the direction of wind does not impact its functionality, it prevents back draught
and protects ventilation ducks from small dirt particles and precipitations.
Dalap Dorn is made of high-quality ABS-plastic resistant against corrosion, UV light and weather conditions.
MOUNTING
1) Unpack the device.
2) Hold the device by its base and put it at the end of ventilation duck output.
3) Check with the construction level implemented in the head that the device is
vertically straight.
4) Fix the device to the ventilation duck with 3 pcs. 25 mm long self-tapping screws.
SAFETY REQUIREMENTS
Please read the instructions carefully. Pay particular attention to the operating requirements.
Operational temperature is between -60 °C and +70 °C.
This device cannot serve as a main ventilation source.
This device cannot be installed at chimneys or vent duck outputs of gas-boiler equipment.
This device is not intended to be used for air exhaust solely in the premises with specific ventilation demands, such as
medical laboratories, chemical and explosion hazardous production facilities etc.
Do not install the device at roof sloping points or other places with high water level. There may not be any water
concentration.
Do not install the pipe near the objects, which can have a negative influence on colour or proper functioning of the
device.
When mounting the devices at the roof surface, it is obligatory to follow safety rules and act with due care.
The device is not intended for use by persons (including children) with reduced physical, mental capacity, or mental
abilities or lack of experience or knowledge, unless they are supervised or instructed to use the device by a person
responsible for their safety. Children should be supervised to ensure that they do not play with the device.
ATTENTION!
In order to avoid precipitation intrusion, the device must be installed over the ventilation duct (its outer diameter).
Do not knock or press on the rotating part of the device in order to avoid disbalancing
The device is not aimed to be installed at dynamic or movable surfaces. Check the immobility of the surface before
installation. Fasten and immobilize it if needed.
The device is not to be installed in wind shadow areas to prevent operation failures.
Installing the device using a at base, snow layer height is to be taken into consideration. Nanodeflector must be
installed over the average rate of the snow layer height (depending on the region and weather area). If there're no
special requirements, the minimum rate is considered to be no less than 300 mm.
