Read this manual carefully before using the product and keep it in a safe place for
reference.
This product was constructed up to standard and in compliance with regulations relating
to electrical equipment and must be installed by technically qualified personnel.
The manufacturer assumes no responsibility for damage to persons or property resulting
from failure to observe the regulations contained in this booklet.
Precautions For installation, use and Maintenance
• The device should not be used for applications other than those specified in this manual.
• After removing the product from its packaging, verify its condition. In case of doubt,
contact a qualified technician. Do not leave packaging within the reach of small
children or people with disabilities.
• Do not touch the appliance with wet or damp hands/feet.
• This appliance can be used by children aged from 8 years and above and persons with
reduced physical, sensory or mental capabilities or lack of experience and knowledge
if they have been given supervision or instruction concerning use of the appliance
in a safe way and understand the hazards involved. Children shall not play with the
appliance. Cleaning and user maintenance shall not be made by children without
supervision.
• Do not use the product in the presence of flammable vapours, such as alcohol,
insecticides, gasoline, etc.
• If any abnormalities in operation are detected, disconnect the device from the mains
supply and contact a qualified technician immediately. Use original spare parts only
for repairs.
• The electrical system to which the device is connected must comply with 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. If not,
contact a qualified technician.
• 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. It must expel air outside via its own special duct.
• Operating temperature: 0°C up to +50°C.
• 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 leave the device exposed to atmospheric agents (rain, sun, snow, etc.).
• Do not immerse the device or its parts in water or other liquids.
• Turn off the main switch whenever a malfunction is detected or when cleaning.
• For installation an omnipolar switch should be incorporated in the fixed wiring,
in accordance with the wiring regulations, to provide a full disconnection under
overvoltage category III conditions (contact opening distance equal to or greater
than 3mm).
• If the supply cord is damaged, it must be replaced by the manufacturer, its service
agent or similarly qualified persons in order to avoid a hazard.
• Do not obstruct the fan or exhaust grille to ensure optimum air passage.
• Ensure adequate air return into the room in compliance with existing regulations in
order to ensure proper device operation.

• 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.
• Install the product so that the impeller is not accessible from the air outlet side as
verified by contact with the Test Finger (test probe "B" of the norm EN61032) in
compliance with the current safety regulations.
introduction
QB is an axial fan designed to ensure air extraction in small rooms such as bathrooms
e toilets. Suitable for air discharge directly to the outside or in the presence of short
linear duct (less than 1.5m). Wall or ceiling installation.
technical sPeciFications
• High efficiency aerodynamic fan with "winglet" blades to optimise quietness and
efficiency.
• Single phase induction motor with integral thermal protection.
• The fan is double insulated: no earth connection is required.
• Power supply 220V to 240V~ 50/60Hz.
• IPX4 wall installation / IPX2 ceiling installation.
Versions
standard
The fan is operated using a separate ON/OFF switch or via a light switch (fig. 10A).
With tiMer (over-run )
The fan is provided with a timer circuit which is adjustable from aprox. 1 minute to 25
minutes via trimmer (fig. 11B).
Operation: connected according to the diagram in fig. 11A, after the light is switched
on, the fan activates with a delay of max 1.5 seconds. After the light is switched off, the
fan continues to function for a pre-set period of time.
