INSTALLATION

 

• After removing the product from its packaging, verify its conditions. Do not leave packaging within the reach of children or people with disabilities.
• Beware of sharp edges. Use protective gloves.
• The device should not be used as an activator for water heaters, stoves, etc., nor should it discharge into hot air/fume vent ducts deriving from any type of  

combustion unit or tumble dryer. It must expel air outside via its own special duct.

• If the environment in which the product is installed also houses a fuel-operating device (water heater, methane stove etc., that is not a “sealed chamber”  

type), it is essential to ensure adequate air intake, to ensure good combustion and proper equipment operation.

• The electrical system to which the device is connected must comply with local regulations.
• Before connecting the product to the power supply or the power outlet, ensure that: 

- the data plate (voltage and frequency) correspond to those of the electrical mains 
- the electrical power supply/socket is adequate for maximum device power

• For installation an omnipolar switch should be incorporated in the fixed wiring, in accordance with the wiring rules, to provide a full disconnection under  

overvoltage category III conditions (contact opening distance equal to or greater than 3mm). 

USE

• The device should not be used for applications other than those specified in this manual.
• The device is not intended for use by persons (including children) with reduced physical, sensory or mental capacities or those with a lack of experience and   

knowledge, unless they have been given supervision or instruction concerning use of the device from a person responsible for their safety. Children should 
be supervised to ensure that they do not play with the device.

• Do not touch the appliance with wet or damp hands/feet.
• The device is designed to extract clean air only, i.e. without grease, soot, chemical or corrosive agents, or flammable or explosive mixtures. 
• Do not use the product in the presence of inflammable vapours, such as alcohol, insecticides, gasoline, etc.
• 

The system should operate continuously, and only be stopped for maintenance/service.

• Do not obstruct ducts or grilles to ensure optimum air passage.
• Do not immerse the device or its parts in water or other liquids.
• Operating temperature: 0°C up to +40 °C. 

SERVICE

• Although the mains supply to the unit has been disconnected there is still risk for injury due to rotating parts that have not come to a complete standstill. 
• Beware of sharp edges. Use protective gloves. 
• Use original spare parts only for repairs.
